Abstract

An essential phenomenon in the development towards syntactic maturity after early childhood is the increasing use of so-called sentence-combining transformations. Especially by using subordination, complex sentences are produced. The research reported here is an attempt to arrive at a more adequate characterization and explanation. Our starting point was an analysis of 280 texts written by Dutch-speaking pupils of the two highest grades of the primary school and the four lowest grades of three different types of secondary education. It was examined whether systematic shifts in the use of certain groups of so-called function words could be traced. We concluded that the development of the syntactic formulating ability can be characterized as an increase in connectivity: the use of all kinds of function words which explicitly mark logico-semantic relations between propositions. This development starts by inserting special adverbs and coordinating conjunctions resulting in various types of coordination. In a later stage, the syntactic patterning of the sentence is affected as well (various types of subordination). The increase in sentence complexity is only one aspect of the entire development. An explanation for the increase in connectivity is offered based upon a distinction between narrative and expository language use. The latter, but not the former, is characterized by frequent occurrence of connectives. The development in syntactic formulating ability includes a high level of skill in expository language use. Speed of development is determined by intensity of training, e.g. in scholastic and occupational settings.

Abstract

Meermalen is getracht om syntactische formuleenuuirdigheid direct en objectief te meten aan de hand van gesproken of geschreven teksten. Uitgangspunt hierbij vormde in de regel de syntactische complexiteit van de geproduceerde taaluitingen. Dit heeft echter niet geleid tot een plausibele, duidelijk omschreven en praktisch bruikbare index. N.a.v. een kritische bespreking van de notie complexiteit wordt in dit artikel als nieuw criterium voorgesteld de connectiviteit van de taaluitingen; de expliciete aanduiding van logiscli-scmantische relaties tussen proposities. Connectiviteit is gemakkelijk scoorbaar aan de hand van functiewoorden die verschillende vormen van nevenschikkend en onderschikkend zinsverband markeren. Deze nieuwe index ondetrangt de kritiek die op complexiteit gegeven kon worden, blijkt duidelijk te discrimineren tussen groepen leerlingen die van elkaar verschillen naar leeftijd en opleidingsniveau, en sluit aan bij recente taalpsychologische en sociolinguïstische theorie. Tot besluit worden enige onderwijskundige implicaties aangegeven.

Abstract

This study investigates the onset at periodic intervals in the age range of about two to five years of various kinds of recurrent and systematic errors in word choice and/or syntactic structure. Acquisitional processes and their implications are outlined. Sections address: (1) the kinds of processes that can be inferred to underlie errors ("late errors") that do not set in until after a period of correct usage; (2) the currently dominant model of how linguistic forms, meaning, and communication are interrelated in the acquisition of language; (3) challenging problems for this model; (4) a suggestion that the notion of "meaning" in language must be reconceptualized before the problems can be solved; and (5) evidence from several types of late errors that supports the arguments. The error types discussed show the ways in which the relationship between form and meanings can change in the course of language development. These changes occur after the child would ordinarily already be credited with having "acquired" the forms in question. This indicates that achieving fluent, productive use of a form and achieving adult-like knowledge of its structure are not necessarily isomorphic.

Abstract

In an earlier study, it was shown that listeners can use prosodic cues that predict where sentence stress will fall; phoneme-monitoring RTs are faster when the preceding prosody indicates that the word bearing the target will be stressed. Two experiments which further investigate this effect are described. In the first, it is shown that the duration of the closure preceding the release of the target stop consonant burst does not affect the RT advantage for stressed words. In the second, it is shown that fundamental frequency variation is not a necessary component of the prosodic variation that produces the predicted-stress effect. It is argued that sentence processing involves a very flexible use of prosodic information.

Abstract

Reaction time to detect a phoneme target in a sentence was found to be faster when the word in which the target occurred formed part of the semantic focus of the sentence. Focus was determined by asking a question before the sentence; that part of the sentence which comprised the answer to the sentence was assumed to be focussed. This procedure made it possible to vary position offocus within the sentence while holding all acoustic aspects of the sentence itself constant. It is argued that sentence understanding is facilitated by rapid identification of focussed information. Since focussed words are usually accented, it is further argued that the active search for accented words demonstrated in previous research should be interpreted as a search for semantic focus.

Abstract

The process of speaking is traditionally regarded as a mapping of thoughts (intentions, feelings, etc.) onto language. One requirement that this mapping has to meet is that the units of information to be expressed be strictly ordered. The channel of speech largely prohibits the simultaneous expression of multiple propositions: the speaker has a linearization problem - that is, a linear order has to be determined over any knowledge structure to be formulated. This may be relatively simple if the informational structure has itself an intrinsic linear arrangement, as often occurs with event structures, but it requires special procedures if the structure is more complex, as is often the case in two- or three-dimensional spatial patterns. How, for instance, does a speaker proceed in describing his home, or the layout of his town? Two powerful constraints on linearization derive, on the one hand, from 'mutual knowledge' and, on the other, from working memory limitations. Mutual knowledge may play a role in that the listener can be expected to derive different implicatures from different orderings (compare 'she married and became pregnant' with 'she became pregnant and married'). Mutual knowledge determinants of linearization are essentially pragmatic and cultural, and dependent on the content of discourse. Working memory limitations affect linearization in that a speaker's linearization strategy will minimize memory load during the process of formulating. A multidimensional structure is broken up in such a way that the number of 'return addresses' to be kept in memory will be minimized. This is attained by maximizing the connectivity of the discourse, and by backtracking to stored addresses in a first-in-last-out fashion. These memory determinants of linearization are presumably biological, and independent of the domain of discourse. An important question is whether the linearization requirement is enforced by the oral modality of speech or whether it is a deeper modality-independent property of language use.

Abstract

Van den Broeck (1977, 1980) heeft een pragmatische interpretatie voorgesteld voor de verschillende wijzen waarop leden van hogere en lagere sociaal-economische klassen hun taaluitingen syntaktisch struktureren. Ter ondersteuning hiervan presenteerde hij gegevens m.b.t. gemiddelde zinscomplexiteit bij sprekers uit twee sociaal- conomische klassen in formele en informele gesprekssituaties. Het in dit artikel gerapporteerde onderzoek slaagt er niet in van den Broeck's uitkomsten te repliceren. Waarschijnlijk berusten ze op een contaminatie van gesprekssituatie met taalkeuze (standaardtaal vs. lokaal dialekt). Mede op basis van de nieuwe gegevens wordt i.p.v. de pragmatische interpretatie een vaardigheidsinterpretatie voorgesteld. T.g.v. vooropleiding en beroep beschikken leden van verschillende sociaal- economische klassen over uiteenlopende vaardigheidsniveaus in verhalend (narrative) en verklarend (expository) taalgebruik. Dit uit zich in het gebruik van connectieven: funktiewoorden die logischsemantische relaties tussen proposities uitdrukken.

Abstract

Starting with Ross (1970), various proposals have been made to classify elliptical coordinations and to characterize different languages according to the types of ellipses which they admit. Sanders (1977) discusses four of these proposals, shows that they are inadequate on various grounds and proposes a fifth typology whose central claim is 'evidently correct', as he states (p. 258). In the following, I shall briefly outline this typology and then show that it is inadequate, too. Since there is only one language 1 know — German — I will take all my examples from this language. Moreover, all examples will be straightforward and easy to be judged.

Abstract

It is argued that the dominantly successive nature of language is largely mode-independent and holds equally for sign and for spoken language. A preliminary distinction is made between what is simultaneous or successive in the signal, and what is in the process; these need not coincide, and it is the successiveness of the process that is at stake. It is then discussed extensively for the word/sign level, and in a more preliminary fashion for the clause and discourse level that online processes are parallel in that they can simultaneously draw on various sources of knowledge (syntactic, semantic, pragmatic), but successive in that they can work at the interpretation of only one unit at a time. This seems to hold for both sign and spoken language. In the final section, conjectures are made about possible evolutionary explanations for these properties of language processing.

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

It is an important feature of the human sentence production system that semantic and syntactic processes may overlap in time and do not proceed strictly serially. That is, the process of building the syntactic form of an utterance does not always wait until the complete semantic content for that utterance has been decided upon. On the contrary, speakers will often start pronouncing the first words of a sentence while still working on further details of its semantic content. An important advantage is memory economy. Semantic and syntactic fragments do not have to occupy working memory until complete semantic and syntactic structures for an utterance have been computed. Instead, each semantic and syntactic fragment is processed as soon as possible and is kept in working memory for a minimum period of time. This raises the question of how the sentence production system can maintain syntactic coherence across syntactic fragments. Presumably there are processes of "syntactic bookkeeping" which (1) store in working memory those syntactic properties of a fragmentary sentence which are needed to eliminate ungrammatical continuations, and (2) check whether a prospective continuation is indeed compatible with the sentence constructed so far. In reaction time experiments where subjects described, under time pressure, simple static pictures of an action performed by an actor, the second aspect of syntactic bookkeeping could be demonstrated. This evidence is used for modelling bookkeeping processes as part of a computational sentence generator which aims at simulating the syntactic operations people carry out during spontaneous speech.

Abstract

The psychology of language as developed by Wilhelm Wundt in his fundamental work Die Sprache (1900) has a strongly mentalistic character. The dominating positions held by behaviorism in psychology and structuralism in linguistics have overruled Wundt’s language theory to the effect that it has remained relatively unknown. This situation has changed recently under the influence of transformational linguistics and cognitive psychology. The paper discusses how Wundt applied the basic psychological concepts of apperception and association to language behavior, in particular to the construction and production of sentences during unprepared speech. The final part of the paper is devoted to the work, published in 1917, of the Dutch linguistic scholar Jacques van Ginneken, who elaborated Wundt’s ideas towards an explanation of some syntactic phenomena during the language acquisition of children.

Abstract

Two experiments examined the nature of access, storage, and comprehension of idiomatic phrases. In both studies a Phrase Classification Task was utilized. In this, reaction times to determine whether or not word strings constituted acceptable English phrases were measured. Classification times were significantly faster to idiom than to matched control phrases. This effect held under conditions involving different categories of idioms, different transitional probabilities among words in the phrases, and different levels of awareness of the presence of idioms in the materials. The data support a Lexical Representation Hypothesis for the processing of idioms.
