    Abstract

    How do human cultural inventions such as reading result in neural re-organization? Previous cross-sectional studies have reported extensive effects of literacy on the neural systems for vision and language (Dehaene et al [2010, Science], Castro-Caldas et al [1998, Brain], Petersson et al [1998, NeuroImage], Carreiras et al [2009, Nature]). In this first longitudinal study with completely illiterate participants, we measured brain responses to speech, text, and other categories of visual stimuli with fMRI before and after a group of illiterate participants in India completed a literacy training program in which they learned to read and write Devanagari script. A literate and an illiterate no-training control group were matched to the training group in terms of socioeconomic background and were recruited from the same societal community in two villages of a rural area near Lucknow, India. This design permitted investigating effects of literacy cross-sectionally across groups before training (N=86) as well as longitudinally (training group N=25). The two analysis approaches yielded converging results: Literacy was associated with enhanced, mainly left-lateralized responses to written text along the ventral stream (including lingual gyrus, fusiform gyrus, and parahippocampal gyrus), dorsal stream (intraparietal sulcus), and (pre-) motor systems (pre-central sulcus, supplementary motor area), thalamus (pulvinar), and cerebellum. Significantly reduced responses were observed bilaterally in the superior parietal lobe (precuneus) and in the right angular gyrus. These positive effects corroborate and extend previous findings from cross-sectional studies. However, effects of literacy were specific to written text and (to a lesser extent) to false fonts. Contrary to previous research, we found no direct evidence of literacy affecting the processing of other types of visual stimuli such as faces, tools, houses, and checkerboards. Furthermore, unlike in some previous studies, we did not find any evidence for effects of literacy on responses in the auditory cortex in our Hindi-speaking participants. We conclude that learning to read has a specific and extensive effect on the processing of written text along the visual pathways, including low-level thalamic nuclei, high-level systems in the intraparietal sulcus and the fusiform gyrus, and motor areas. The absence of an effect of literacy on responses in the auditory cortex in particular raises questions about the extent to which phonological representations in the auditory cortex are altered by literacy acquisition or recruited online during reading.

    Abstract

    To what extent is visual attention driven by the semantics of individual objects, rather than by their visual appearance? To investigate this we continuously measured eye movements, while observers searched through displays of common objects for an aurally instructed target. On crucial trials, the target was absent, but the display contained object s that were either semantically or visually related to the target. We hypothesized that timing is crucial in the occurrence and strength of semantic influences on visual orienting, and therefore presented the target instruction either before, during, or af ter (memory - based search) picture onset. When the target instruction was presented before picture onset we found a substantial, but delayed bias in orienting towards semantically related objects as compared to visually related objects. However, this delay disappeared when the visual information was presented before the target instruction. Furthermore, the temporal dynamics of the semantic bias did not change in the absence of visual competition. These results po int to cascadic but independent influences of semantic and visual representations on attention. In addition. the results of the memory - based search studies suggest that visual and semantic biases only arise when the visual stimuli are present. Although we consistent ly found that people fixate at locat ions previously occupied by the target object (a replication of earlier findings), we did not find such biases for visually or semantically related objects. Overall, our studies show that the question whether visual orienting is driven by semantic c ontent is better rephrased as when visual orienting is driven by semantic content.

    Abstract

    Prominent theories of predictive language processing assume that language production processes are used to anticipate upcoming linguistic input during comprehension (Dell & Chang, 2014; Pickering & Garrod, 2013). Here, we explored the converse case: Does a task set including production in addition to comprehension encourage prediction, compared to a task only including comprehension? To test this hypothesis, participants carried out a cross-modal naming task (Exp 1a), a self-paced reading task (Exp1 b) that did not include overt production, and a task (Exp 1c) in which naming and reading trials were evenly interleaved. We used the same predictable (N = 40) and non-predictable (N = 40) sentences in all three tasks. The sentences consisted of a fixed agent, a transitive verb and a predictable or non-predictable target word (The man breaks a glass vs. The man borrows a glass). The mean cloze probability in the predictable sentences was .39 (ranging from .06 to .8; zero in the non-predictable sentences). A total of 162 volunteers took part in the experiment which was run in a between-participants design. In Exp 1a, fifty-four participants listened to recordings of the sentences which ended right before the spoken target word. Coinciding with the end of the playback, a picture of the target word was shown which the participants were asked to name as fast as possible. Analyses of their naming latencies revealed a statistically significant naming advantage of 108 ms on predictable over non-predictable trials. Moreover, we found that the objects’ naming advantage was predicted by the target words’ cloze probability in the sentences (r = .347, p = .038). In Exp 1b, 54 participants were asked to read the same sentences in a self-paced fashion. To allow for testing of potential spillover effects, we added a neutral prepositional phrase (breaks a glass from the collection/borrows a glass from the neighbor) to each sentence. The sentences were read word-by-word, advancing by pushing the space bar. On 30% of the trials, comprehension questions were used to keep up participants' focus on comprehending the sentences. Analyses of their spillover region reading times revealed a numerical advantage (8 ms; tspillover = -1.1, n.s.) in the predictable as compared to the non-predictable condition. Importantly, the analysis of participants' responses to the comprehension questions, showed that they understood the sentences (mean accuracy = 93%). In Exp 1c, the task comprised 50% naming trials and 50% reading trials which appeared in random order. Fifty-four participants named and read the same objects and sentences as in the previous versions. The results showed a naming advantage on predictable over non-predictable items (99 ms) and a positive correlation between the items’ cloze probability and their naming advantage (r = .322, p = .055). Crucially, the post-target reading time analysis showed that with naming trials and reading trials interleaved, there was also a statistically reliable prediction effect on reading trials. Participants were 19 ms faster at reading the spillover region on predictable relative to non-predictable items (tspillover = -2.624). To summarize, although we used the same sentences in all sub-experiments, we observed effects of prediction only when the task set involved production. In the reading only experiment (Exp 1b), no evidence for anticipation was obtained although participants clearly understood the sentences and the same sentences yielded reading facilitation when interleaved with naming trials (Exp 1c). This suggests that predictive language processing can be modulated by the comprehenders’ task set. When the task set involves language production, as is often the case in natural conversation, comprehenders appear to engage in prediction to a stronger degree than in pure comprehension tasks. In our discussion, we will discuss the notion that language production may engage prediction, because being able to predict words another person is about to say might optimize the comprehension process and enable smooth turn-taking.

    Abstract

    A substantial body of literature has shown that readers and listeners often anticipate information. An open question concerns the mechanisms underlying predictive language processing. Multiple mechanisms have been suggested. One proposal is that comprehenders use event knowledge to predict upcoming words. Other theoretical frameworks propose that predictions are made based on simple word associations. In a recent EEG study, Metusalem and colleagues reported evidence for the modulating influence of event knowledge on prediction. They examined the degree to which event knowledge is activated during sentence comprehension. Their participants read two sentences, establishing an event scenario, which were followed by a final sentence containing one of three target words: a highly expected word, a semantically unexpected word that was related to the described event, or a semantically unexpected and event-unrelated word (see Figure, for an example). Analyses of participants’ ERPs elicited by the target words revealed a three-way split with regard to the amplitude of the N400 elicited by the different types of target: the expected targets elicited the smallest N400, the unexpected and event-unrelated targets elicited the largest N400. Importantly, the amplitude of the N400 elicited by the unexpected but event-related targets was significantly attenuated relative to the amplitude of the N400 elicited by the unexpected and event-unrelated targets. Metusalem et al. concluded that event knowledge is immediately available to constrain on-line language processing. Based on a post-hoc analysis, the authors rejected the possibility that the results could be explained by simple word associations. In the present study, we addressed the role of simple word associations in discourse comprehension more directly. Specifically, we explored the contribution of associative priming to the graded N400 pattern seen in Metusalem et al’s study. We conducted two EEG experiments. In Experiment 1, we reran Metusalem and colleagues’ context manipulation and closely replicated their results. In Experiment 2, we selected two words from the event-establishing sentences which were most strongly associated with the unexpected but event-related targets in the final sentences. Each of the two associates was then placed in a neutral carrier sentence. We controlled that none of the other words in these carrier sentences was associatively related to the target words. Importantly, the two carrier sentences did not build up a coherent event. We recorded EEG while participants read the carrier sentences followed by the same final sentences as in Experiment 1. The results showed that as in Experiment 1 the amplitude of the N400 elicited by both types of unexpected target words was larger than the N400 elicited by the highly expected target. Moreover, we found a global tendency towards the critical difference between event-related and event-unrelated unexpected targets which reached statistical significance only at parietal electrodes over the right hemisphere. Because the difference between event-related and event-unrelated conditions was larger when the sentences formed a coherent event compared to when they did not, our results suggest that associative priming alone cannot account for the N400 pattern observed in our Experiment 1 (and in the study by Metusalem et al.). However, because part of the effect remained, probably due to associative facilitation, the findings demonstrate that during discourse reading both event knowledge activation and simple word associations jointly contribute to the prediction process. The results highlight that multiple mechanisms underlie predictive language processing.

    Abstract

    I will discuss recent research with illiterates and individuals with dyslexia which suggests that many cognitive ‚defi ciencies‘ proposed as possible causes of dyslexia are simply a consequence of decreased reading experience. I will argue that in order to make further progress towards an understanding of the causes of dyslexia it is necessary to appropriately distinguish between cause and effect.

    Abstract

    Prominent theories of predictive language processing assume that language production processes are used to anticipate upcoming linguistic input during comprehension (Dell & Chang, 2014; Pickering & Garrod, 2013). Here, we explore the converse case: Does a task set including production in addition to comprehension encourage prediction, compared to a task only including comprehension? To test this hypothesis, we conducted a cross-modal naming experiment (Experiment 1) including an object naming task and a self-paced reading experiment (Experiment 2) that did not include overt production. We used the same predictable (N = 40) and non-predictable (N = 40) sentences in both experiments. The sentences consisted of a fixed agent, a transitive verb and a predictable or non-predictable target word (The man drinks a beer vs. The man buys a beer). Most of the empirical work on prediction used sentences in which the target words were highly predictable (often with a mean cloze probability > .8) and thus it is little surprising that participants engaged in predictive language processing very easily. In the current sentences, the mean cloze probability in the predictable sentences was .39 (ranging from .06 to .8; zero in the non-predictable sentences). If comprehenders are more likely to engage in predictive processing when the task set involves production, we should observe more pronounced effects of prediction in Experiment 1 as compared to Experiment 2. If production does not enhance prediction, we should observe similar effects of prediction in both experiments. In Experiment 1, participants (N = 54) listened to recordings of the sentences which ended right before the spoken target word. Coinciding with the end of the playback, a picture of the target word was shown which the participants were asked to name as fast as possible. Analyses of their naming latencies revealed a statistically significant naming advantage of 106 ms on predictable over non-predictable trials. Moreover, we found that the objects’ naming advantage was predicted by the target words’ cloze probability in the sentences (r = .411, p = .016). In Experiment 2, the same sentences were used in a self-paced reading experiment. To allow for testing of potential spill-over effects, we added a neutral prepositional phrase (buys a beer from the bar keeper/drinks a beer from the shop) to each sentence. Participants (N = 54) read the sentences word-by-word, advancing by pushing the space bar. On 30% of the trials, comprehension questions were used to keep up participants' focus on comprehending the sentences. Analyses of participants’ target and post-target reading times revealed numerical advantages of 6 ms and 20 ms, respectively, in the predictable as compared to the non-predictable condition. However, in both cases, this difference was not statistically reliable (t = .757, t = 1.43) and the significant positive correlation between an item’s naming advantage and its cloze probability as seen in Experiment 1 was absent (r = .037, p = .822). Importantly, the analysis of participants' responses to the comprehension questions, showed that they understood the sentences (mean accuracy = 93%). To conclude, although both experiments used the same sentences, we observed effects of prediction only when the task included production. In Experiment 2, no evidence for anticipation was found although participants clearly understood the sentences and the method has previously been shown to be sensitive to measure prediction effects (Van Berkum et al., 2005). Our results fit with a recent study by Gollan et al. (2011) who found only a small processing advantage of predictive over non-predictive sentences in reading (using highly predictable sentences with a cloze probability > . 87) but a strong prediction effect when participants read the same sentences and carried out an additional object naming task (see also Griffin & Bock, 1998). Taken together, the studies suggest that the comprehenders' task set exerts a powerful influence on the likelihood and magnitude of predictive language processing. When the task set involves language production, as is often the case in natural conversation, comprehenders might engage in prediction to a stronger degree than in pure comprehension tasks. Being able to predict words another person is about to say might optimize the comprehension process and enable smooth turn-taking.

    Abstract

    A central claim of embodied theories of cognition is that sensory representations are
    routinely activated and influence language processing even in the absence of relevant
    sensory input (cf. Pulvermüller, 2005; Wassenburg & Zwaan, 2010). We tested the influence
    of color representations during language processing in three visual world eye tracking
    experiments. The method is particularly well suited to investigate this issue because the
    availability of relevant visual input can be manipulated.
    We made use of the phenomena that when participants hear a word that refers to a
    visual object or printed word they quickly direct their eye gaze to objects or printed words
    which are similar (e.g. semantically or visually) to the heard word. We used a look and listen
    task which previously has been shown to be sensitive to such relationships between spoken
    words and visual items. In Experiment 1, on experimental trials, participants listened to
    sentences containing a critical target word associated with a prototypical color (e.g.
    '...spinach...') as they inspected a visual display with four words printed in black font. One of
    the four printed words was associated with the same prototypical color (e.g. green) as the
    spoken target word (e.g. FROG). On experimental trials, the spoken target word did not have
    a printed word counterpart (SPINACH was not present in the display). In filler trials (70% of
    trials) the target was present in the display and attracted significantly more overt attention
    than the unrelated distractors. In experimental trials color competitors were not looked at
    more than the distractors. In Experiment 2 the printed words were replaced with line
    drawings of the objects. In order to direct the attentional focus of our participants toward
    color features we used a within-participants counter-balanced design and alternated color
    and greyscale trials randomly throughout the experiment. Therefore, on one trial our
    participants heard a word such as 'spinach' and saw a frog (colored in green) in the visual
    display. On the next trial however they saw a banana (in greyscale) on hearing 'canary'
    (bananas and canaries are typically yellow), etc. The presence (or absence) of color was
    thus a salient property of the experiment. Participants looked more at color competitors than
    unrelated distractors on hearing the target word in the color trials but not in the greyscale
    trials, i.e. on hearing 'spinach' they looked at the green frog but not the greyscale frog.
    Experiment 3 was identical to Experiment 2, except that the visual display was removed at
    the sentence onset, after a longer preview. This experiment examined whether the continued
    presence of color in the immediate visual environment was necessary for the observation of
    color-mediated eye movements. Eye movements directed towards the now blank screen
    were recorded as the sentence unfolded (cf. Spivey & Geng, 2001). In the filler trials,
    participants looked significantly more at the locations where the targets, rather than the
    distractors, had been previously presented as the target words acoustically unfolded. In the
    experimental trials, the locations where the color competitors had previously been presented
    did not attract increased attention (neither in color nor greyscale trials).
    These data demonstrate that language-mediated eye movements are only influenced
    by color relations between spoken words and visually displayed items if color is present in the immediate visual environment. We conclude that color representations are unlikely to be
    routinely activated in language processing. Our findings provide strong constraints for
    embodied theories of cognition which assume that sensory representations influence language processing even in the absence of relevant sensory input. These results fit best with the notion that the main role of sensory representations in language processing is a different one, namely to contextualize language in the immediate environment, connecting language to the here and now.

    Abstract

    The notion that predicting upcoming linguistic information in language comprehension makes use of the production system has recently received much attention (e.g., Chang et al., 2006; Dell & Chang, 2014; Federmeier, 2007; Pickering & Garrod, 2007, 2013; Van Berkum et al., 2005). So far there has been little experimental evidence for a relation between prediction and production. I will discuss the results of several recent eye-tracking experiments with toddlers (Mani & Huettig, 2012) and adults (Rommers et al. submitted, Hintz et al., in prep.) which provide some support for the view that production abilities are linked to language-mediated anticipatory eye movements. These data however also indicate that production-based prediction is situation-dependent and only one of many mechanisms supporting prediction. Taken together, these results suggest that multiple-mechanism accounts are required to provide a complete picture of anticipatory language processing.

    Abstract

    Recent empirical evidence suggests that language-mediated eye gaze around the visual world varies across individuals and is partly determined by their level of formal literacy training. Huettig, Singh & Mishra (2011) showed that unlike high-literate individuals, whose eye gaze was closely time locked to phonological overlap between a spoken target word and items presented in a visual display, low-literate individuals eye gaze was not tightly locked to phonological overlap in the speech signal but instead strongly influenced by semantic relationships between items. Our present study tests the hypothesis that this behaviour is an emergent property of an increased ability to extract phonological structure from the speech signal, as in the case of high-literates, with low-literates more reliant on syllabic structure. This hypothesis was tested using an emergent connectionist model, based on the Hub-and-spoke models of semantic processing (Dilkina et al, 2008), that integrates linguistic information extracted from the speech signal with visual and semantic information within a central resource. We demonstrate that contrasts in fixation behaviour similar to those observed between high and low literates emerge when the model is trained on either a speech signal segmented by phoneme (i.e. high-literates) or by syllable (i.e. low-literates).
