Abstract

Three- and four-year-old children were asked predicate-focus questions ('What's X doing?') about a scene in which an agent performed an action on a patient. We varied: (i) whether (or not) the preceding discourse context, which established the patient as given information, was available for the questioner; and (ii) whether (or not) the patient was perceptually available to the questioner when she asked the question. The main finding in our study differs from those of previous studies since it suggests that children are sensitive to the perceptual context at an earlier age than they are to previous discourse context if they need to take the questioner's perspective into account. Our finding indicates that, while children are in principle sensitive to both factors, young children rely on perceptual availability when a conflict arises.

Abstract

Attention-deficit hyperactivity disorder (ADHD) is a common behavioral disorder affecting about 4–8% of children. ADHD persists into adulthood in around 65% of cases, either as the full condition or in partial remission with persistence of symptoms. Pharmacological, animal and molecular genetic studies support a role for genes of the dopaminergic system in ADHD due to its essential role in motor control, cognition, emotion, and reward. Based on these data, we analyzed two functional polymorphisms within the DRD4 gene (120 bp duplication in the promoter and 48 bp VNTR in exon 3) in a clinical sample of 1,608 adult ADHD patients and 2,352 controls of Caucasian origin from four European countries that had been recruited in the context of the International Multicentre persistent ADHD CollaboraTion (IMpACT). Single-marker analysis of the two polymorphisms did not reveal association with ADHD. In contrast, multiple-marker meta-analysis showed a nominal association (P  = 0.02) of the L-4R haplotype (dup120bp-48bpVNTR) with adulthood ADHD, especially with the combined clinical subtype. Since we previously described association between adulthood ADHD and the dopamine transporter SLC6A3 9R-6R haplotype (3′UTR VNTR-intron 8 VNTR) in the same dataset, we further tested for gene × gene interaction between DRD4 and SLC6A3. However, we detected no epistatic effects but our results rather suggest additive effects of the DRD4 risk haplotype and the SLC6A3 gene.

Abstract

Does our perception of others’ emotional signals depend on the language we speak or is our perception the same regardless of language and culture? It is well established that human emotional facial expressions are perceived categorically by viewers, but whether this is driven by perceptual or linguistic mechanisms is debated. We report an investigation into the perception of emotional facial expressions, comparing German speakers to native speakers of Yucatec Maya, a language with no lexical labels that distinguish disgust from anger. In a free naming task, speakers of German, but not Yucatec Maya, made lexical distinctions between disgust and anger. However, in a delayed match-to-sample task, both groups perceived emotional facial expressions of these and other emotions categorically. The magnitude of this effect was equivalent across the language groups, as well as across emotion continua with and without lexical distinctions. Our results show that the perception of affective signals is not driven by lexical labels, instead lending support to accounts of emotions as a set of biologically evolved mechanisms.

Abstract

In the current study we use electroencephalography (EEG) to detect heard music from the brain signal, hypothesizing that the time structure in music makes it especially suitable for decoding perception from EEG signals. While excluding music with vocals, we classified the perception of seven different musical fragments of about three seconds, both individually and cross-participants, using only time domain information (the event-related potential, ERP). The best individual results are 70% correct in a seven-class problem while using single trials, and when using multiple trials we achieve 100% correct after six presentations of the stimulus. When classifying across participants, a maximum rate of 53% was reached, supporting a general representation of each musical fragment over participants. While for some music stimuli the amplitude envelope correlated well with the ERP, this was not true for all stimuli. Aspects of the stimulus that may contribute to the differences between the EEG responses to the pieces of music are discussed.

Abstract

This paper explores the use of demonstratives in non-embedded clausal nominalisations. We present data and analysis from three Papuan languages of the Timor-Alor-Pantar family in south-east Indonesia. In these languages, demonstratives can apply to the clausal as well as to the nominal domain, contributing contrastive semantic content in assertive stance-taking and attention-directing utterances. In the Timor-Alor-Pantar constructions, meanings that are to do with spatial and discourse locations at the participant level apply to spatial, temporal and mental locations at the state or event leve

Abstract

Work on animals indicates that BOLD is preferentially sensitive to local field potentials, and that it correlates most strongly with gamma band neuronal synchronization. Here we investigate how the BOLD signal in humans performing a cognitive task is related to neuronal synchronization across different frequency bands. We simultaneously recorded EEG and BOLD while subjects engaged in a visual attention task known to induce sustained changes in neuronal synchronization across a wide range of frequencies. Trial-by-trial BOLD luctuations correlated positively with trial-by-trial fluctuations in high-EEG gamma power (60–80 Hz) and negatively with alpha and beta power. Gamma power on the one hand, and alpha and beta power on the other hand, independently contributed to explaining BOLD variance. These results indicate that the BOLD-gamma coupling observed in animals can be extrapolated to humans performing a task and that neuronal dynamics underlying high- and low-frequency synchronization contribute independently to the BOLD signal.

Abstract

This study investigates whether or not the representation of lexical stress information can be primed during speech production. In four experiments, we attempted to prime the stress position of bisyllabic target nouns (picture names) having initial and final stress with auditory prime words having either the same or different stress as the target (e.g., WORtel–MOtor vs. koSTUUM–MOtor; capital letters indicate stressed syllables in prime–target pairs). Furthermore, half of the prime words were semantically related, the other half unrelated. Overall, picture names were not produced faster when the prime word had the same stress as the target than when the prime had different stress, i.e., there was no stress-priming effect in any experiment. This result would not be expected if stress were stored in the lexicon. However, targets with initial stress were responded to faster than final-stress targets. The reason for this effect was neither the quality of the pictures nor frequency of occurrence or voice-key characteristics. We hypothesize here that this stress effect is a genuine encoding effect, i.e., words with stress on the second syllable take longer to be encoded because their stress pattern is irregular with respect to the lexical distribution of bisyllabic stress patterns, even though it can be regular with respect to metrical stress rules in Dutch. The results of the experiments are discussed in the framework of models of phonological encoding.

Abstract

Any complete theory of speaking must take the dialogical function of language use into account. Pickering & Garrod (P&G) make some progress on this point. However, we question whether their interactive alignment model is the optimal approach. In this commentary, we specifically criticize (1) their notion of alignment being implemented through priming, and (2) their claim that self-monitoring can occur at all levels of linguistic representation.

Abstract

This study investigates whether or not masked form priming effects in the naming task depend on the number of shared segments between prime and target. Dutch participants named bisyllabic words, which were preceded by visual masked primes. When primes shared the initial segment(s) with the target, naming latencies were shorter than in a control condition (string of percent signs). Onset complexity (singleton vs. complex word onset) did not modulate this priming effect in Dutch. Furthermore, significant priming due to shared final segments was only found when the prime did not contain a mismatching onset, suggesting an interfering role of initial non-target segments. It is concluded that (a) degree of overlap (segmental match vs. mismatch), and (b) position of overlap (initial vs. final) influence the magnitude of the form priming effect in the naming task. A modification of the segmental overlap hypothesis (Schiller, 1998) is proposed to account for the data.

Abstract

To investigate the role of the syllable in Dutch speech production, five experiments were carried out to examine the effect of visually masked syllable primes on the naming latencies for written words and pictures. Targets had clear syllable boundaries and began with a CV syllable (e.g., ka.no) or a CVC syllable (e.g., kak.tus), or had ambiguous syllable boundaries and began with a CV[C] syllable (e.g., ka[pp]er). In the syllable match condition, bisyllabic Dutch nouns or verbs were preceded by primes that were identical to the target’s first syllable. In the syllable mismatch condition, the prime was either shorter or longer than the target’s first syllable. A neutral condition was also included. None of the experiments showed a syllable priming effect. Instead, all related primes facilitated the naming of the targets. It is concluded that the syllable does not play a role in the process of phonological encoding in Dutch. Because the amount of facilitation increased with increasing overlap between prime and target, the priming effect is accounted for by a segmental overlap hypothesis.

Abstract

This study examines the placement of finite and nonfinite lexical verbs and finite light verbs (LVs) in semispontaneous production and elicited imitation of adult beginning learners of German and French. Theories assuming nonnativelike syntactic representations at early stages of development predict variable placement of lexical verbs and consistent placement of LVs, whereas theories assuming nativelike syntax predict variability for nonfinite verbs and consistent placement of all finite verbs. The results show that beginning learners of German have consistent preferences only for LVs. More advanced learners of German and learners of French produce and imitate finite verbs in more variable positions than nonfinite verbs. This is argued to support a structure-building view of second-language development.

Abstract

The study endeavors a detailed and systematic classification of linguistic simultaneity expressions. Further, it aims at a well described survey of how simultaneity is expressed by native speakers in their own language. On the basis of real production data the book answers the questions of how native speakers express temporal simultaneity in general, and how learners at different levels of proficiency deal with this situation under experimental test conditions. Furthermore, the results of this study shed new light on our understanding of aspect in general, and on its acquisition by adult learners.

Abstract

Studying the interaction between brain regions is important to increase our understanding of brain function. Magnetoencephalography (MEG) is well suited to investigate brain connectivity, because it provides measurements of activity of the whole brain at very high temporal resolution. Typically, brain activity is reconstructed from the sensor recordings with an inverse method such as a beamformer, and subsequently a connectivity metric is estimated between predefined reference regions-of-interest (ROIs) and the rest of the source space. Unfortunately, this approach relies on a robust estimate of the relevant reference regions and on a robust estimate of the activity in those reference regions, and is not generally applicable to a wide variety of cognitive paradigms. Here, we investigate the possibility to perform all-to-all pairwise connectivity analysis, thus removing the need to define ROIs. Particularly, we evaluate the effect of nonhomogeneous spatial smoothing of differential connectivity maps. This approach is inspired by the fact that the spatial resolution of source reconstructions is typically spatially nonhomogeneous. We use this property to reduce the spatial noise in the cerebro-cerebral connectivity map, thus improving interpretability. Using extensive data simulations we show a superior detection rate and a substantial reduction in the number of spurious connections. We conclude that nonhomogeneous spatial smoothing of cerebro-cerebral connectivity maps could be an important improvement of the existing analysis tools to study neuronal interactions noninvasively.

Abstract

Local groups of neurons engaged in a cognitive task often exhibit rhythmically synchronized activity in the gamma band, a phenomenon that likely enhances their impact on downstream areas. The efficacy of neuronal interactions may be enhanced further by interareal synchronization of these local rhythms, establishing mutually well timed fluctuations in neuronal excitability. This notion suggests that long-range synchronization is enhanced selectively for connections that are behaviorally relevant. We tested this prediction in the human motor system, assessing activity from bilateral motor cortices with magnetoencephalography and corresponding spinal activity through electromyography of bilateral hand muscles. A bimanual isometric wrist extension task engaged the two motor cortices simultaneously into interactions and coherence with their respective corresponding contralateral hand muscles. One of the hands was cued before each trial as the response hand and had to be extended further to report an unpredictable visual go cue. We found that, during the isometric hold phase, corticomuscular coherence was enhanced, spatially selective for the corticospinal connection that was effectuating the subsequent motor response. This effect was spectrally selective in the low gamma-frequency band (40–47 Hz) and was observed in the absence of changes in motor output or changes in local cortical gamma-band synchronization. These findings indicate that, in the anatomical connections between the cortex and the spinal cord, gamma-band synchronization is a mechanism that may facilitate behaviorally relevant interactions between these distant neuronal groups.

Abstract

In spontaneous, conversational speech, words are often reduced compared to their citation forms, such that a word like yesterday may sound like [’jεsmall eshei]. The present chapter investigates such acoustic reduction. The study of reduction needs large corpora that are transcribed phonetically. The first part of this chapter describes an automatic transcription procedure used to obtain such a large phonetically transcribed corpus of Dutch spontaneous dialogues, which is subsequently used for the investigation of acoustic reduction. First, the orthographic transcriptions were adapted for automatic processing. Next, the phonetic transcription of the corpus was created by means of a forced alignment using a lexicon with multiple pronunciation variants per word. These variants were generated by applying phonological and reduction rules to the canonical phonetic transcriptions of the words. The second part of this chapter reports the results of a quantitative analysis of reduction in the corpus on the basis of the generated transcriptions and gives an inventory of segmental reductions in standard Dutch. Overall, we found that reduction is more pervasive in spontaneous Dutch than previously documented.

Abstract

Gender assignment relates to a native speaker's knowledge of the structure of the gender system of his/her language, allowing the speaker to select the appropriate gender for each noun. Whereas categorical assignment rules and exceptional gender assignment are well investigated, assignment regularities, i.e., tendencies in the gender distribution identified within the vocabulary of a language, are still controversial. The present study is an empirical contribution trying to shed light on the gender assignment system native German speakers have at their disposal. Participants presented with a category (e.g., predator) and a pair of gender-marked pseudowords (e.g., der Trelle vs. die Stisse) preferentially selected the pseudo-word preceded by the gender-marked determiner ‘‘associated’’ with the category (e.g., masculine). This finding suggests that semantic regularities might be part of the gender assignment system of native speakers.

Abstract

Speakers tend to repeat syntactic structures across sentences, a phenomenon called syntactic priming. Although it has been suggested that repeating syntactic structures should result in speeded responses, previous research has focused on effects in response tendencies. We investigated syntactic priming effects simultaneously in response tendencies and response latencies for active and passive transitive sentences in a picture description task. In Experiment 1, there were priming effects in response tendencies for passives and in response latencies for actives. However, when participants' pre-existing preference for actives was altered in Experiment 2, syntactic priming occurred for both actives and passives in response tendencies as well as in response latencies. This is the first investigation of the effects of structure frequency on both response tendencies and latencies in syntactic priming. We discuss the implications of these data for current theories of syntactic processing.

Abstract

The present study investigates the functions of gestures in preschoolers’ descriptions of activities. Specifically, utilizing McNeill’s growth point theory (1992), I examine how gestures contribute to the creation of contrast from the immediate context in the spoken discourse of children. When preschool children describe an activity consisting of multiple actions, like playing on a slide, they often begin with the central action (e.g., sliding-down) instead of with the beginning of the activity sequence (e.g., climbing-up). This study indicates that, in descriptions of activities, gestures may be among the cues the speaker uses for forming a next idea or for repairing the temporal order of the activities described. Gestures may function for the speaker as visual feedback and contribute to the process of utterance formation and provide an index for assessing language development.

Abstract

This article discusses how the Trobriand Islanders speak about body and mind. It addresses the following questions: do the linguistic datafit into theories about lexical universals of body-part terminology? Can we make inferences about the Trobrianders' conceptualization of psychological and physical states on the basis of these data? If a Trobriand Islander sees these idioms as external manifestations of inner states, then can we interpret them as a kind of ethnopsychological theory about the body and its role for emotions, knowledge, thought, memory, and so on? Can these idioms be understood as representation of Trobriand ethnopsychological theory?

Abstract

When we communicate, we communicate in a certain context, and this context shapes our utterances. Natural languages are context-bound and deixis 'concerns the ways in which languages encode or grammaticalise features of the context of utterance or speech event, and thus also concerns ways in which the interpretation of utterances depends on the analysis of that context of utterance' (Stephen Levinson). The systems of deixis and demonstratives in the Oceanic languages represented in the contributions to this volume illustrate the fascinating complexity of spatial reference in these languages. Some of the studies presented here highlight social aspects of deictic reference illustrating de Leon's point that 'reference is a collaborative task' . It is hoped that this anthology will contribute to a better understanding of this area and provoke further studies in this extremely interesting, though still rather underdeveloped, research area.

Abstract

How stable is the lexicon for perceptual experiences? This article presents results on how the Trobriand Islanders of Papua New Guinea talk about color and taste and whether this has changed over the years. Comparing the results of research on color terms conducted in 1983 with data collected in 2008 revealed that many English color terms have been integrated into the Kilivila lexicon. Members of the younger generation with school education have been the agents of this language change. However, today not all English color terms are produced correctly according to English lexical semantics. The traditional Kilivila color terms bwabwau ‘black’, pupwakau ‘white’, and bweyani ‘red’ are not affected by this change, probably because of the cultural importance of the art of coloring canoes, big yams houses, and bodies. Comparing the 1983 data on taste vocabulary with the results of my 2008 research revealed no substantial change. The conservatism of the Trobriand Islanders' taste vocabulary may be related to the conservatism of their palate. Moreover, they are more interested in displaying and exchanging food than in savoring it. Although English color terms are integrated into the lexicon, Kilivila provides evidence that traditional terms used for talking about color and terms used to refer to tastes have remained stable over time.

Abstract

The Trobriand Islanders' eschatological belief system explains what happens when someone dies. Bronislaw Malinowski described essentials of this eschatology in his articles "Baloma: the Spirits of the Dead in the Trobriand Islands" and "Myth in Primitive Psychology" There he also presented the Trobrianders' belief that a "baloma" can be reborn; he claimed that Trobrianders are unaware of the father's role as genitor. This volume presents a critical review of Malinowski's ethnography of Trobriand eschatology - finally settling the "virgin birth" controversy. It also documents the ritualized and highly poetic "wosi milamala" - the harvest festival songs. They are sung in an archaic variety of Kilivila called "biga baloma" - the baloma language. Malinowski briefly refers to these songs but does not mention that they codify many aspects of Trobriand eschatology. The songs are still sung at specific occasions; however, they are now moribund. With these songs Trobriand eschatology will vanish. The e-book is made available under a CC BY-NC-ND 4.0 license. http://creativecommons.org/licenses/by-nc-nd/4.0/

Abstract

A new sign language has been created by deaf Nicaraguans over the past 25 years, providing an opportunity to observe the inception of universal hallmarks of language. We found that in their initial creation of the language, children analyzed complex events into basic elements and sequenced these elements into hierarchically structured expressions according to principles not observed in gestures accompanying speech in the surrounding language. Successive cohorts of learners extended this procedure, transforming Nicaraguan signing from its early gestural form into a linguistic system. We propose that this early segmentation and recombination reflect mechanisms with which children learn, and thereby perpetuate, language. Thus, children naturally possess learning abilities capable of giving language its fundamental structure.

Abstract

Models of speech production disagree on whether or not homonyms have a shared word-form representation. To investigate this issue, a picture-naming experiment was carried out using Dutch homonyms of which both meanings could be presented as a picture. Naming latencies for the low-frequency meanings of homonyms were slower than for those of the high-frequency meanings. However, no frequency effect was found for control words, which matched the frequency of the homonyms meanings. Subsequent control experiments indicated that the difference in naming latencies for the homonyms could be attributed to processes earlier than wordform retrieval. Specifically, it appears that low name agreement slowed down the naming of the low-frequency homonym pictures.

Abstract

Speakers use vocabulary for spatial verticality and size to describe pitch. A high–low contrast is common to many languages, but others show contrasts like thick–thin and big–small. We consider uses of thick for low pitch and thin for high pitch in three languages: Farsi, Turkish, and Zapotec. We ask how metaphors for pitch structure the sound space. In a language like English, high applies to both high-pitched as well as high-amplitude (loud) sounds; low applies to low-pitched as well as low-amplitude (quiet) sounds. Farsi, Turkish, and Zapotec organize sound in a different way. Thin applies to high pitch and low amplitude and thick to low pitch and high amplitude. We claim that these metaphors have their sources in life experiences. Musical instruments show co-occurrences of higher pitch with thinner, smaller objects and lower pitch with thicker, larger objects. On the other hand bodily experience can ground the high–low metaphor. A raised larynx produces higher pitch and lowered larynx lower pitch. Low-pitched sounds resonate the chest, a lower place than highpitched sounds. While both patterns are available from life experience, linguistic experience privileges one over the other, which results in differential structuring of the multiple dimensions of sound.

Abstract

Listeners tune in to talkers’ vowels through extrinsic normalization. We asked here whether this process could be based on compensation for the Long Term Average Spectrum (LTAS) of preceding sounds and whether the mechanisms responsible for normalization are indifferent to the nature of those sounds. If so, normalization should apply to nonspeech stimuli. Previous findings were replicated with first formant (F1) manipulations of speech. Targets on a [pIt]-[pEt] (low-high F1) continuum were labeled as [pIt] more after high-F1 than after low-F1 precursors. Spectrally-rotated nonspeech versions of these materials produced similar normalization. None occurred, however, with nonspeech stimuli that were less speech-like, even though precursor-target LTAS relations were equivalent to those used earlier. Additional experiments investigated the roles of pitch movement, amplitude variation, formant location, and the stimuli's perceived similarity to speech. It appears that normalization is not restricted to speech, but that the nature of the preceding sounds does matter. Extrinsic normalization of vowels is due at least in part to an auditory process which may require familiarity with the spectro-temporal characteristics of speech.

Abstract

This study used an active multiple-deviant oddball design to investigate the time-course of normalization processes that help listeners deal with between-speaker variability. Electroencephalograms were recorded while Dutch listeners heard sequences of non-words (standards and occasional deviants). Deviants were [ɪ papu] or [ɛ papu], and the standard was [ɪɛpapu], where [ɪɛ] was a vowel that was ambiguous between [ɛ] and [ɪ]. These sequences were presented in two conditions, which differed with respect to the vocal-tract characteristics (i.e., the average 1st formant frequency) of the [papu] part, but not of the initial vowels [ɪ], [ɛ] or [ɪɛ] (these vowels were thus identical across conditions). Listeners more often detected a shift from [ɪɛpapu] to [ɛ papu] than from [ɪɛpapu] to [ɪ papu] in the high F1 context condition; the reverse was true in the low F1 context condition. This shows that listeners’ perception of vowels differs depending on the speaker‘s vocal-tract characteristics, as revealed in the speech surrounding those vowels. Cortical electrophysiological responses reflected this normalization process as early as about 120 ms after vowel onset, which suggests that shifts in perception precede influences due to conscious biases or decision strategies. Listeners’ abilities to normalize for speaker-vocal-tract properties are for an important part the result of a process that influences representations of speech sounds early in the speech processing stream.

Abstract

Adult speakers of different free stress languages (e.g., English, Spanish) differ both in their sensitivity to lexical stress and in their processing of suprasegmental and vowel quality cues to stress. In a head-turn preference experiment with a familiarization phase, both 8-month-old and 12-month-old English-learning infants discriminated between initial stress and final stress among lists of Spanish-spoken disyllabic nonwords that were segmentally varied (e.g. [ˈnila, ˈtuli] vs [luˈta, puˈki]). This is evidence that English-learning infants are sensitive to lexical stress patterns, instantiated primarily by suprasegmental cues, during the second half of the first year of life.

Abstract

A quantitative model of human categorization behavior is proposed, which can be applied to 4-alternative forced-choice categorization data involving two binary classifications. A number of processing dependencies between the two classifications are explicitly formulated, such as the dependence of the location, orientation, and steepness of the class boundary for one classification on the outcome of the other classification. The significance of various types of dependencies can be tested statistically. Analyses of a data set from the literature shows that interesting dependencies in human speech recognition can be uncovered using the model.

Abstract

The way a language encodes sensory experiences changes over time, and often this correlates with other changes in the society. There are noticeable differences in the language of perception between older and younger speakers of Cantonese in Hong Kong and Macau. Younger speakers make finer distinctions in the distal senses, but have less knowledge of the finer categories of the proximal senses than older speakers. The difference in the language of perception between older and younger speakers probably reflects the rapid changes that happened in Hong Kong and Macau in the last fifty years, from an underdeveloped and lessliterate society, to a developed and highly literate society. In addition to the increase in literacy, the education system has also undergone significant Westernization. Western-style education systems have most likely created finer categorizations in the distal senses. At the same time, the traditional finer distinctions of the proximal senses have become less salient: as the society became more urbanized and sanitized, people have had fewer opportunities to experience the variety of olfactory sensations experienced by their ancestors. This case study investigating interactions between social-economic 'development' and the elaboration of the senses hopefully contributes to the study of the ineffability of senses.

Abstract

Relying on the methodology of conversation analysis, this article examines a practice in ordinary conversation characterized by the resaying of a word, phrase, or sentence. The article shows that multiple sayings such as "No no no" or "Alright alright alright" are systematic in both their positioning relative to the interlocutor's talk and in their function. Specifically, the findings are that multiple sayings are a resource speakers have to display that their turn is addressing an in progress course of action rather than only the just prior utterance. Speakers of multiple sayings communicate their stance that the prior speaker has persisted unnecessarily in the prior course of action and should properly halt course of action.

Abstract

Each time we take a turn in conversation we indicate what we know and what we think others know. However, knowledge is neither static nor absolute. It is shaped by those we interact with and governed by social norms - we monitor one another for whether we are fulfilling our rights and responsibilities with respect to knowledge, and for who has relatively more rights to assert knowledge over some state of affairs. This book brings together an international team of leading linguists, sociologists and anthropologists working across a range of European and Asian languages to document some of the ways in which speakers manage the moral domain of knowledge in conversation. The volume demonstrates that if we are to understand how speakers manage issues of agreement, affiliation and alignment - something clearly at the heart of human sociality - we must understand the social norms surrounding epistemic access, primacy and responsibilities

Abstract

This study investigates whether spoken sentence comprehension deficits in Broca's aphasics results from their inability to access the subordinate meaning of ambiguous words (e.g. bank), or alternatively, from a delay in their selection of the contextually appropriate meaning. Twelve Broca's aphasics and twelve elderly controls were presented with lexical ambiguities in three context conditions, each followed by the same target words. In the concordant condition, the sentence context biased the meaning of the sentence final ambiguous word that was related to the target. In the discordant condition, the sentence context biased the meaning of the sentence final ambiguous word that was incompatible with the target.In the unrelated condition, the sentence-final word was unambiguous and unrelated to the target. The task of the subjects was to listen attentively to the stimuli The activational status of the ambiguous sentence-final words was inferred from the amplitude of the N399 to the targets at two inter-stimulus intervals (ISIs) (100 ms and 1250 ms). At the short ISI, the Broca's aphasics showed clear evidence of activation of the subordinate meaning. In contrast to elderly controls, however, the Broca's aphasics were not successful at selecting the appropriate meaning of the ambiguity in the short ISI version of the experiment. But at the long ISI, in accordance with the performance of the elderly controls, the patients were able to successfully complete the contextual selection process. These results indicate that Broca's aphasics are delayed in the process of contextual selection. It is argued that this finding of delayed selection is compatible with the idea that comprehension deficits in Broca's aphasia result from a delay in the process of integrating lexical information.

Abstract

This volume on Inuit speech follows the evolution of a native language of the North American Arctic, from its historical roots to its present-day linguistic structure and patterns of use from Alaska to Greenland. Drawing on a wide range of research from the fields of linguistics, anthropology, and sociology, Dorais integrates these diverse perspectives in a comprehensive view of native language development, maintenance, and use under conditions of marginalization due to social transition.

Abstract

The roles which word class (open/closed) and sentential stress play in the sentence comprehension processes of both agrammatic (Broca's) aphasics and normal listeners were examined with a word monitoring task. Overall, normal listeners responded more quickly to stressed than to unstressed items, but showed no effect of word class. Aphasics also responded more quickly to stressed than to unstressed materials, but, unlike the normals, responded faster to open than to closed class words regardless of their stress. The results are interpreted as support for the theory that Broca's aphasics lack the functional underlying open/closed class word distinction used in word recognition by normal listeners.

Abstract

This work presents a salvage grammar of the Biri language of Eastern Central Queensland, a Pama-Nyungan language belonging to the large Maric subgroup. As the language is no longer used, the grammatical description is based on old written sources and on recordings made by linguists in the 1960s and 1970s. Biri is in many ways typical of the Pama-Nyungan languages of Southern Queensland. It has split case marking systems, marking nouns according to an ergative/absolutive system and pronouns according to a nominative/accusative system. Unusually for its area, Biri also has bound pronouns on its verb, cross-referencing the person, number and case of core participants. As far as it is possible, the grammatical discussion is ‘theory neutral’. The first four chapters deal with the phonology, morphology, and syntax of the language. The last two chapters contain a substantial discussion of Biri’s place in the Pama-Nyungan family. In chapter 6 the numerous dialects of the Biri language are discussed. In chapter 7 the close linguistic relationship between Biri and the surrounding languages is examined.

Abstract

The Papuan-Oceanic world has long been considered a hotbed of contact-induced linguistic change, and there have been a number of studies of deep linguistic influence between Papuan and Oceanic languages (like those by Thurston and Ross). This paper assesses the degree and type of contact-induced language change in the Solomon Islands, between the four Papuan languages—Bilua (spoken on Vella Lavella, Western Province), Touo (spoken on southern Rendova, Western Province), Savosavo (spoken on Savo Island, Central Province), and Lavukaleve (spoken in the Russell Islands, Central Province)—and their Oceanic neighbors. First, a claim is made for a degree of cultural homogeneity for Papuan and Oceanic-speaking populations within the Solomons. Second, lexical and grammatical borrowing are considered in turn, in an attempt to identify which elements in each of the four Papuan languages may have an origin in Oceanic languages—and indeed which elements in Oceanic languages may have their origin in Papuan languages. Finally, an assessment is made of the degrees of stability versus change in the Papuan and Oceanic languages of the Solomon Islands.

Abstract

In individuals with ASD, difficulties with language comprehension are most evident when higher-level semantic-pragmatic language processing is required, for instance when context has to be used to interpret the meaning of an utterance. Until now, it is unclear at what level of processing and for what type of context these difficulties in language comprehension occur. Therefore, in the current fMRI study, we investigated the neural correlates of the integration of contextual information during auditory language comprehension in 24 adults with ASD and 24 matched control participants. Different levels of context processing were manipulated by using spoken sentences that were correct or contained either a semantic or world knowledge anomaly. Our findings demonstrated significant differences between the groups in inferior frontal cortex that were only present for sentences with a world knowledge anomaly. Relative to the ASD group, the control group showed significantly increased activation in left inferior frontal gyrus (LIFG) for sentences with a world knowledge anomaly compared to correct sentences. This effect possibly indicates reduced integrative capacities of the ASD group. Furthermore, world knowledge anomalies elicited significantly stronger activation in right inferior frontal gyrus (RIFG) in the control group compared to the ASD group. This additional RIFG activation probably reflects revision of the situation model after new, conflicting information. The lack of recruitment of RIFG is possibly related to difficulties with exception handling in the ASD group.

Abstract

In many areas of language acquisition, researchers have suggested that semantic generality plays an important role in determining the order of acquisition of particular lexical forms. However, generality is typically confounded with the effects of input frequency and it is therefore unclear to what extent semantic generality or input frequency determines the early acquisition of particular lexical items. The present study evaluates the relative influence of semantic status and properties of the input on the acquisition of verbs and their argument structures in the early speech of 9 English-speaking children from 2;0 to 3;0. The children's early verb utterances are examined with respect to (1) the order of acquisition of particular verbs in three different constructions, (2) the syntactic diversity of use of individual verbs, (3) the relative proportional use of semantically general verbs as a function of total verb use, and (4) their grammatical accuracy. The data suggest that although measures of semantic generality correlate with various measures of early verb use, once the effects of verb use in the input are removed, semantic generality is not a significant predictor of early verb use. The implications of these results for semantic-based theories of verb argument structure acquisition are discussed.

Abstract

Right hemisphere dominance for visuospatial attention is characteristic of most humans, but its anatomical basis remains unknown. We report the first evidence in humans for a larger parieto-frontal network in the right than left hemisphere, and a significant correlation between the degree of anatomical lateralization and asymmetry of performance on visuospatial tasks. Our results suggest that hemispheric specialization is associated with an unbalanced speed of visuospatial processing.

Abstract

The present study compares the realization of intervocalic voiceless stops and vowels surrounded by voiceless stops in conversational Spanish and French. Our data reveal significant differences in how these segments are realized in each language. Spanish voiceless stops tend to have shorter stop closures, display incomplete closures more often, and exhibit more voicing than French voiceless stops. As for vowels, more cases of complete devoicing and greater degrees of partial devoicing were found in French than in Spanish. Moreover, all French vowel types exhibit significantly lower F1 values than their Spanish counterparts. These findings indicate that the extent of reduction that a segment type can undergo in conversational speech can vary significantly across languages. Language differences in coarticulatory strategies and “base-of-articulation” are discussed as possible causes of our observations.

Abstract

This study investigates the reduction of vowel /e/ in the French word c’était /setε/ ‘it was’. This reduction phenomenon appeared to be highly frequent, as more than half of the occurrences of this word in a corpus of casual French contained few or no acoustic traces of a vowel between [s] and [t]. All our durational analyses clearly supported a categorical absence of vowel /e/ in a subset of c’était tokens. This interpretation was also supported by our finding that the occurrence of complete elision and [e] duration in non-elision tokens were conditioned by different factors. However, spectral measures were consistent with the possibility that a highly reduced /e/ vowel is still present in elision tokens in spite of the durational evidence for categorical elision. We discuss how these findings can be reconciled, and conclude that acoustic analysis of uncontrolled materials can provide valuable information about the mechanisms underlying reduction phenomena in casual speech.

Abstract

In the interplay between language, culture, and perception, iconicity structures our representations of what we experience. By examining secondary iconicity in sensory vocabulary, this study draws attention to diagrammatic qualities in human interaction with, and representation of, the sensory world. In Semai (Mon-Khmer, Aslian), spoken on Peninsular Malaysia, sensory experiences are encoded by expressives. Expressives display a diagrammatic iconic structure whereby related sensory experiences receive related linguistic forms. Through this type of formmeaning mapping, gradient relationships in the perceptual world receive gradient linguistic representations. Form-meaning mapping such as this enables speakers to categorize sensory events into types and subtypes of perceptions, and provide illustrates how a diagrammatic iconic structure within sensory vocabulary creates networks of relational sensory knowledge. Through analogy, speakers draw on this knowledge to comprehend sensory referents and create new unconventional forms, which are easily understood by other members of the community. Analogy-making such as this allows speakers to capture fine-grained differences between sensory events, and effectively guide each other through the Semai sensory landscape. sensory specifics of various kinds.

Abstract

In sequences such as law and order, speakers of British English often insert /r/ between law and and. Acoustic analyses revealed such “intrusive” /r/ to be significantly shorter than canonical /r/. In a 2AFC experiment, native listeners heard British English sentences in which /r/ duration was manipulated across a word boundary [e.g., saw (r)ice], and orthographic and semantic factors were varied. These listeners responded categorically on the basis of acoustic evidence for /r/ alone, reporting ice after short /r/s, rice after long /r/s; orthographic and semantic factors had no effect. Dutch listeners proficient in English who heard the same materials relied less on durational cues than the native listeners, and were affected by both orthography and semantic bias. American English listeners produced intermediate responses to the same materials, being sensitive to duration (less so than native, more so than Dutch listeners), and to orthography (less so than the Dutch), but insensitive to the semantic manipulation. Listeners from language communities without common use of intrusive /r/ may thus interpret intrusive /r/ as canonical /r/, with a language difference increasing this propensity more than a dialect difference. Native listeners, however, efficiently distinguish intrusive from canonical /r/ by exploiting the relevant acoustic variation.

Abstract

This study investigates the lifespans of lexical traces for novel morphologically complex words. In two visual lexical decision experiments, a neologism was either primed by itself or by its stem. The target occurred 40 trials after the prime (Experiments 1 & 2), after a 12 hour delay (Experiment 1), or after a one week delay (Experiment 2). Participants recognized neologisms more quickly if they had seen them before in the experiment. These results show that memory traces for novel morphologically complex words already come into existence after a very first exposure and that they last for at least a week. We did not find evidence for a role of sleep in the formation of memory traces. Interestingly, Base Frequency appeared to play a role in the processing of the neologisms also when they were presented a second time and had their own memory traces.

Abstract

An event-related brain potential experiment was carried out to investigate the influence of semantic and syntactic context constraints on lexical selection and integration in spoken-word comprehension. Subjects were presented with constraining spoken sentences that contained a critical word that was either (a) congruent, (b) semantically and syntactically incongruent, but beginning with the same initial phonemes as the congruent critical word, or (c) semantically and syntactically incongruent, beginning with phonemes that differed from the congruent critical word. Relative to the congruent condition, an N200 effect reflecting difficulty in the lexical selection process was obtained in the semantically and syntactically incongruent condition where word onset differed from that of the congruent critical word. Both incongruent conditions elicited a large N400 followed by a left anterior negativity (LAN) time-locked to the moment of word category violation and a P600 effect. These results would best fit within a cascaded model of spoken-word processing, proclaiming an optimal use of contextual information during spokenword identification by allowing for semantic and syntactic processing to take place in parallel after bottom-up activation of a set of candidates, and lexical integration to proceed with a limited number of candidates that still match the acoustic input.

Abstract

In normal conversation, speakers translate thoughts into words at high speed. To enable this speed, the retrieval of distinct types of linguistic knowledge has to be orchestrated with millisecond precision. The nature of this orchestration is still largely unknown. This report presents dynamic measures of the real-time activation of two basic types of linguistic knowledge, syntax and phonology. Electrophysiological data demonstrate that during noun-phrase production speakers retrieve the syntactic gender of a noun before its abstract phonological properties. This two-step process operates at high speed: the data show that phonological information is already available 40 milliseconds after syntactic properties have been retrieved.

Abstract

We report on a prospective longitudinal research programme exploring the connection between language acquisition deficits and dyslexia. The language development profile of children at-risk for dyslexia is compared to that of age-matched controls as well as of children who have been diagnosed with specific language impairment (SLI). The experiments described concern the perception and production of grammatical morphology, categorical perception of speech sounds, phonological processing (non-word repetition), mispronunciation detection, and rhyme detection. The results of each of these indicate that the at-risk children as a group underperform in comparison to the controls, and that, in most cases, they approach the SLI group. It can be concluded that dyslexia most likely has precursors in language development, also in domains other than those traditionally considered conditional for the acquisition of literacy skills. The dyslexia-SLI connection awaits further, particularly qualitative, analyses.

Abstract

Synesthesia provides an elegant model to investigate neural mechanisms underlying individual differences in subjective experience in humans. In grapheme–color synesthesia, written letters induce color sensations, accompanied by activation of color area V4. Competing hypotheses suggest that enhanced V4 activity during synesthesia is either induced by direct bottom-up cross-activation from grapheme processing areas within the fusiform gyrus, or indirectly via higher-order parietal areas. Synesthetes differ in the way synesthetic color is perceived: “projector” synesthetes experience color externally colocalized with a presented grapheme, whereas “associators” report an internally evoked association. Using dynamic causal modeling for fMRI, we show that V4 cross-activation during synesthesia was induced via a bottom-up pathway (within fusiform gyrus) in projector synesthetes, but via a top-down pathway (via parietal lobe) in associators. These findings show how altered coupling within the same network of active regions leads to differences in subjective experience. Our findings reconcile the two most influential cross-activation accounts of synesthesia.

Abstract

An introductory study of the perception of stochastically specified events is reported. The initial problem was to determine whether the perceiver can split visual input data of this kind into random and determined components. The inability of subjects to do so with the stimulus material used (a filmlike sequence of dot patterns), led to the more general question of how subjects code this kind of visual material. To meet the difficulty of defining the subjects' responses, two experiments were designed. In both, patterns were presented as a rapid sequence of dots on a screen. The patterns were more or less disturbed by “noise,” i.e. the dots did not appear exactly at their proper places. In the first experiment the response was a rating on a semantic scale, in the second an identification from among a set of alternative patterns. The results of these experiments give some insight in the coding systems adopted by the subjects. First, noise appears to be detrimental to pattern recognition, especially to patterns with little spread. Second, this shows connections with the factors obtained from analysis of the semantic ratings, e.g. easily disturbed patterns show a large drop in the semantic regularity factor, when only a little noise is added.

Abstract

Three experiments investigated the voicing distinction in Dutch initial labial and alveolar plosives. The difference between voiced and voiceless Dutch plosives is generally described in terms of the presence or absence of prevoicing (negative voice onset time). Experiment 1 showed, however, that prevoicing was absent in 25% of voiced plosive productions across 10 speakers. The production of prevoicing was influenced by place of articulation of the plosive, by whether the plosive occurred in a consonant cluster or not, and by speaker sex. Experiment 2 was a detailed acoustic analysis of the voicing distinction, which identified several acoustic correlates of voicing. Prevoicing appeared to be by far the best predictor. Perceptual classification data revealed that prevoicing was indeed the strongest cue that listeners use when classifying plosives as voiced or voiceless. In the cases where prevoicing was absent, other acoustic cues influenced classification, such that some of these tokens were still perceived as being voiced. These secondary cues were different for the two places of articulation. We discuss the paradox raised by these findings: although prevoicing is the most reliable cue to the voicing distinction for listeners, it is not reliably produced by speakers.

Abstract

The monitoring theory of language perception proposes that competing representations that are caused by strong expectancy violations can trigger a conflict which elicits reprocessing of the input to check for possible processing errors. This monitoring process is thought to be reflected by the P600 component in the EEG. The present study further investigated this monitoring process by comparing syntactic and spelling violations in an EEG and an fMRI experiment. To assess the effect of conflict strength, misspellings were embedded in sentences that were weakly or strongly predictive of a critical word. In support of the monitoring theory, syntactic and spelling violations elicited similarly distributed P600 effects. Furthermore, the P600 effect was larger to misspellings in the strongly compared to the weakly predictive sentences. The fMRI results showed that both syntactic and spelling violations increased activation in the left inferior frontal gyrus (lIFG), while only the misspellings activated additional areas. Conflict strength did not affect the hemodynamic response to spelling violations. These results extend the idea that the lIFG is involved in implementing cognitive control in the presence of representational conflicts in general to the processing of errors in language perception.

Abstract

A corpus of Dutch falling-rising intonation contours with early nuclear accent was elicited from nine speakers with a view to establishing the extent to which the low F0 target immediately preceding the final rise, was attracted by a post-nuclear stressed syllable (PNS) in either of the last two words or by Second Occurrence Contrastive Focus (SOCF) on either of these words. We found a small effect of foot type, which we interpret as due to a rhythmic 'trochaic enhancement' effect. The results show that neither PNS nor SOCF influences the location of the low F0 target, which appears consistently to be timed with reference to the utterance end. It is speculated that there are two ways in which postnuclear tones can be timed. The first is by means of a phonological association with a post-nuclear stressed syllable, as in Athenian Greek and Roermond Dutch. The second is by a fixed distance from the utterance end or from the target of an adjacent tone. Accordingly, two phonological mechanisms are defended, association and edge alignment, such that all tones edge-align, but only some associate. Specifically, no evidence was found for a third situation that can be envisaged, in which a post-nuclear tone is gradiently attracted to a post-nuclear stress.

Abstract

I thank the speakers of Yurakaré who have taught me their language for sharing their knowledge with me. I would furthermore like to thank Grev Corbett, Michael Cysouw, and an anonymous reviewer for commenting on earlier drafts of this paper. All remaining errors are mine. The research reported in this paper was made possible by grants from Prof. Pieter Muysken’s Spinoza project Lexicon & Syntax, the University of Surrey, the DoBeS foundation, and the Netherlands Organization for Scientific Research, for which I am grateful. Pronominal affixes in polysynthetic languages have an ambiguous status in the sense that they have characteristics normally associated with free pronouns as well as characteristics associated with agreement markers. This situation arises because pronominal affixes represent intermediate stages in a diachronic development from independent pronouns to agreement markers. Because this diachronic change is not abrupt, pronominal affixes can show different characteristics from language to language. By presenting an in-depth discussion of the pronominal affixes of Yurakaré, an unclassified language from Bolivia, I argue that these so-called intermediate stages as typically attested in polysynthetic languages actually represent economical systems that combine advantages of agreement markers and of free pronouns. In terms of diachronic development, such ‘intermediate’ systems, being functionally well-adapted, appear to be rather stable, and it can even be reinforced by subsequent diachronic developments.

Abstract

As a preliminary to further research on musical consonance an explanatory investigation was made on the different modes of judgment of musical intervals. This was done by way of a semantic differential. Subjects rated 23 intervals against 10 scales. In a factor analysis three factors appeared: pitch, evaluation and fusion. The relation between these factors and some physical characteristics has been investigated. The scale consonant-dissonant showed to be purely evaluative (in opposition to Stumpf's theory). This evaluative connotation is not in accordance with the musicological meaning of consonance. Suggestions to account for this difference have been given.

Abstract

Yurakaré (unclassified, central Bolivia) marks core arguments on the verb by means of pronominal affixes. Subjects are suffixed, objects are prefixed. There are six types of head-marked objects in Yurakaré, each with its own morphosyntactic and semantic properties. Distributional patterns suggest that the six objects can be divided into two larger groups reminiscent of the typologically recognized direct vs. indirect object distinction. This paper looks at the interaction of this complex system of participant marking and verbal semantics. By investigating the participant-marking patterns of nine verb classes (four representing a gradual decrease of patienthood of the P participant, five a gradual decrease of agentivity of the A participant), I come to the conclusion that grammatical roles in Yurakaré can be defined semantically, and case frames are to a high degree determined by verbal semantics.

Abstract

In terms of its linguistic and cultural make-up, the continent of South America provides linguists and anthropologists with a complex puzzle of language diversity. The continent teems with small language families and isolates, and even languages spoken in adjacent areas can be typologically vastly different from each other. This volume intends to provide a taste of the linguistic diversity found in South America within the area of clause subordination. The potential variety in the strategies that languages can use to encode subordinate events is enormous, yet there are clearly dominant patterns to be discerned: switch reference marking, clause chaining, nominalization, and verb serialization. The book also contributes to the continuing debate on the nature of syntactic complexity, as evidenced in subordination.

Abstract

Humans respond to unfair situations in various ways. Experimental research has revealed that non-human species also respond to unequal situ- ations in the form of inequity aversions when they have the disadvantage. The current study focused on play fights in gorillas to explore for the first time, to our knowledge, if/how non-human species respond to inequities in natural social settings. Hitting causes a naturally occurring inequity among individuals and here it was specifically assessed how the hitters and their partners engaged in play chases that followed the hitting. The results of this work showed that the hitters significantly more often moved first to run away immediately after the encounter than their partners. These findings provide evidence that non-human species respond to inequities by trying to maintain their competitive advantages. We conclude that non-human pri- mates, like humans, may show different responses to inequities and that they may modify them depending on if they have the advantage or the disadvantage.

Abstract

Listeners require context to understand the highly reduced words that occur in casual speech. The present study reports four auditory lexical decision experiments in which the role of semantic context in the comprehension of reduced versus unreduced speech was investigated. Experiments 1 and 2 showed semantic priming for combinations of unreduced, but not reduced, primes and low-frequency targets. In Experiment 3, we crossed the reduction of the prime with the reduction of the target. Results showed no semantic priming from reduced primes, regardless of the reduction of the targets. Finally, Experiment 4 showed that reduced and unreduced primes facilitate upcoming low-frequency related words equally if the interstimulus interval is extended. These results suggest that semantically related words need more time to be recognized after reduced primes, but once reduced primes have been fully (semantically) processed, these primes can facilitate the recognition of upcoming words as well as do unreduced primes.

Abstract

Onderzoek naar taal en communicatie heeft zich in het verleden veel te veel gericht op taal als systeem om berichten te coderen, een soort TCP/IP (netwerkprotocol voor communicatie tussen computers). Dat moet maar eens veranderen, stelt prof. dr. Jos van Berkum, hoogleraar Discourse, Cognitie en Communicatie, in zijn oratie die hij op 30 september zal houden aan de Universiteit Utrecht. Hij pleit voor meer onderzoek naar de sterke verwevenheid van taal en gevoel.

Abstract

The present study explored whether language-nonselective access in bilinguals occurs across word classes in a sentence context. Dutch–English bilinguals were auditorily presented with English (L2) sentences while looking at a visual world. The sentences contained interlingual homophones from distinct lexical categories (e.g., the English verb spoke, which overlaps phonologically with the Dutch noun for ghost, spook). Eye movement recordings showed that depictions of referents of the Dutch (L1) nouns attracted more visual attention than unrelated distractor pictures in sentences containing homophones. This finding shows that native language objects are activated during second language verb processing despite the structural information provided by the sentence context. Research highlights We show that native language words are activated during second language sentence processing. We tested this in a visual world setting on homophones with a different word class across languages. Fixations show that processing second language verbs activated native language nouns.

Abstract

The current study investigated the effects of phonologically related context pictures on the naming latencies of target words in Japanese and Chinese. Reading bare words in alphabetic languages has been shown to be rather immune to effects of context stimuli, even when these stimuli are presented in advance of the target word (e. g., Glaser & Dungelhoff, 1984; Roelofs, 2003). However, recently, semantic context effects of distractor pictures on the naming latencies of Japanese kanji (but not Chinese hanzi) words have been observed (Verdonschot, La Heij, & Schiller, 2010). In the present study, we further investigated this issue using phonologically related (i.e., homophonic) context pictures when naming target words in either Chinese or Japanese. We found that pronouncing bare nouns in Japanese is sensitive to phonologically related context pictures, whereas this is not the case in Chinese. The difference between these two languages is attributed to processing costs caused by multiple pronunciations for Japanese kanji.

Abstract

Theories of language production generally describe the segment as the basic unit in phonological encoding (e.g., Dell, 1988; Levelt, Roelofs, & Meyer, 1999). However, there is also evidence that such a unit might be language specific. Chen, Chen, and Dell (2002), for instance, found no effect of single segments when using a preparation paradigm. To shed more light on the functional unit of phonological encoding in Japanese, a language often described as being mora based, we report the results of 4 experiments using word reading tasks and masked priming. Experiment 1 demonstrated using Japanese kana script that primes, which overlapped in the whole mora with target words, sped up word reading latencies but not when just the onset overlapped. Experiments 2 and 3 investigated a possible role of script by using combinations of romaji (Romanized Japanese) and hiragana; again, facilitation effects were found only when the whole mora and not the onset segment overlapped. Experiment 4 distinguished mora priming from syllable priming and revealed that the mora priming effects obtained in the first 3 experiments are also obtained when a mora is part of a syllable. Again, no priming effect was found for single segments. Our findings suggest that the mora and not the segment (phoneme) is the basic functional phonological unit in Japanese language production planning.
