SUMMARY:Learning new words: Implications for speech processing and for lexical memory by James M. McQueen
DESCRIPTION:Learning new words: Implications for speech processing and for lexical memory by James M. McQueen (Radboud University\, Nijmegen\, The Netherlands)\nlle et al.\, 2012; Schwartze & Kotz\, 2013). I will discuss new empirical and patient evidence (motor-auditory coupling and auditory only) in support of these considerations and present an extended cortico-subcortical framework encompassing action-perception coupling\, perception\, and multimodal speech.\nur\, Aix-en-Provence LPL\nListeners are able to recognise words in spite of considerable variation in how words are realized physically. For example\, Mary may need to recognise an English word spoken by Jacques\, a non-native speaker that Mary has never heard before. Evidence from behavioural (eye-tracking) and neuroscientific (EEG and fMRI) studies on novel word learning will be presented which suggests that listeners cope with the variation in spoken words through abstracting away from the episodic details of particular experienced word forms. This process can be seen in on-line speech recognition: the way a novel realization of a new word is processed is based on phonological knowledge previously abstracted from other words. The need for abstraction also shapes lexical memory: sleep-enhanced memory consolidation processes support the transfer of newly-learned words from episodic memory to long-term lexical memory\, making generalization across modalities possible. Listeners can recognise\, for example\, newly-learned words that they have previously read but that they have never heard before.

SUMMARY:Figures of speech in the brain: The role of metaphoricity\, familiarity\, concreteness\, and lateralization in language comprehension by Bálint Forgács
DESCRIPTION:Figures of speech in the brain: The role of metaphoricity\, familiarity\, concreteness\, and lateralization in language comprehension by Bálint Forgács (Laboratoire Psychologie de la Perception (LPP) Université Paris Descartes)\nDebates are hot regarding how metaphors are related to literal language\, in what steps we understand them\, and how our brains deal with them. In my talk I am going to show fMRI and divided visual half field data arguing against a unique role for the right cerebral hemisphere and literal language in metaphor comprehension. If the relevant psycholinguistic factors are controlled for (such as context\, emotional valence or imageability) classical left lateralized regions seem to compute not just dead\, but even novel metaphors. Moreover\, the latter do not seem to evoke the so called electrophysiological concreteness effect either\, contrary to the claims of the strong version of embodiment. Based on the new evidence I am going to present a novel model of how the neural systems dedicated to language could compute figures of speech so swiftly and quickly\, and why the lateralization debate could be viewed from a different perspective.

SUMMARY:Man and Machine during Natural Language Processing: A Neurocognitive Approach by Chris Biemann and Markus J. Hofmann
DESCRIPTION:Man and Machine during Natural Language Processing: A Neurocognitive Approach by Chris Biemann and Markus J. Hofmann Language Technology\, Universität Hamburg General and Biological Psychology\, University of Wuppertal\nWhile state-of-the-art NLP models lack a theory that systematically accounts for human performance at all levels of linguistic analysis\, Neurocognitive Simulation Models of orthographic and phonological memory so far lacked a level of implemented semantic representations. To overcome these limitations\, the authors of this talk decided to initiate a long-standing cooperation.\n\nIn part 1 of this talk\, we introduce unsupervised methods from language technology that capture semantic information. We present a range of methods that extract semantic representation from corpora\, as opposed to using manually created norms. We show how we applied language models based on n-grams\, topic modelling\, and the word2vec neural model across three different corpora to account for behavioral\, brain-electric and eye movement data. We used a benchmark that has become standard for Neurocognitive Simulation Models in psychology: Thus we reproducibly accounted for half of the item-level variance in the cloze-completion-based word predictability from sentence context\, and the resulting N400-\, and single fixation duration data of the Potsdam sentence corpus.\n\nIn part 2 we discuss how relatively straightforward NLP methods can be used to define semantic processes in a neurocognitive simulation model. To extend an interactive activation model with a semantic layer\, we used the log likelihood that two words occur more often together in the sentences of a large corpus than predictable by single-word frequency. The resulting Associative Read-Out Model (AROM) is an extension of the Multiple Read-Out Model. Here\, we use it to account for association ratings and semantically induced false memories in human performance and P200/N400 brain-electric data. Then\, we present a sequential version of the AROM accounting for primed lexical decision\, and the resulting semantic competition in the left (and right!) inferior frontal gyrus of the human brain. Finally\, we envision two routes of reading\, complementing the form-based aspects of linguistic representations with one of the most defining feature of words: they carry meaning.

SUMMARY:Semantic processing beyond categories: Influences of semantic richness\, associations and social-communicative contexts on language production by Rasha Abdel Rahman
DESCRIPTION:Semantic processing beyond categories: Influences of semantic richness\, associations and social-communicative contexts on language production by  Rasha Abdel Rahman (Humboldt-Universität zu Berlin)\nThe ultimate goal of speaking is to convey meaning. However\, while semantic-categorical relations are well-investigated\, little is known about other aspects of meaning processing during speech planning. In this talk I will present evidence on how message-inherent attributes\, for instance\, the semantic richness or emotional content of the message\, shape language production. Furthermore\, I will discuss the flexible nature of the language production system that can adapt to different contexts from ad-hoc relations to associations and social-communicative situations. Together\, these findings demonstrate a high level of flexibility of the language production system as a basis for intimate - and thus far underinvestigated - relations between language production\, emotion and social cognition.

SUMMARY:Annotating Information Structure in Authentic Data: From Expert Annotation to Crowd Sourcing Experiments by Detmar Meurers\, Kordula De Kuthy (University of Tübingen)
DESCRIPTION:Annotating Information Structure in Authentic Data: From Expert Annotation to Crowd Sourcing Experiments by Detmar Meurers\, Kordula De Kuthy (University of Tübingen)\nWhile the formal pragmatic concepts in information structure\, such as the focus of an utterance\, are precisely defined in theoretical linguistics and potentially very useful in conceptual and practical terms\, it has turned out to be difficult to reliably annotate such notions in corpus data (Ritz et al.\, 2008; Calhoun et al.\, 2010). We present a large-scale focus annotation effort designed to overcome this problem. Our annotation study is based on the tasked-based corpus CREG (Ott et al.\, 2012)\, which consists of answers to explicitly given reading comprehension questions. We compare focus annotation by trained annotators with a crowd-sourcing setup making use of untrained native speakers. Given the task context and an annotation process incrementally making the question form and answer type explicit\, the trained annotators reach substantial agreement for focus annotation. Interestingly\, the crowd-sourcing setup also supports high-quality annotation\, for specific subtypes of data. To refine the crowd-sourcing setup\, we introduce the Consensus Cost as a measure of agreement within the crowd. We investigate the usefulness of Consensus Cost as a measure of crowd annotation quality both intrinsically\, in relation to the expert gold standard\, and extrinsically\, by integrating focus annotation information into a system performing Short Answer Assessment taking into account the Consensus Cost. Finally\, we turn to the question whether the relevance of focus annotation can be extrinsically evaluated. We show that automatic short-answer assessment indeed significantly improves for focus annotated data.

SUMMARY:Perceptual adaptation and speech motor control: A new perspective on some well known mechanisms by Douglas Shiller
DESCRIPTION:Perceptual adaptation and speech motor control: A new perspective on some well known mechanisms by Douglas Shiller (Université de Montréal\, Faculté de médecine)\nAcoustic speech signals are notoriously variable within and between talkers. To aid in the linguistic decoding of such noisy signals\, it is well known that listeners employ a number of perceptual mechanisms to help reduce the impact of linguistically irrelevant acoustic variation. Rapid perceptual accommodation to differences in age and gender is achieved\, in part\, through vowel-extrinsic normalization\, whereby the immediately preceding speech signal provides a frame-of-reference within which talker-specific vowel category boundaries are determined (Ladefoged & Broadbent\, 1957). Listeners also draw upon higher-order linguistic information to facilitate phonetic processing of noisy or ambiguous speech acoustic signals\, as illustrated by the well-known lexical effect on perceptual category boundaries (Ganong\, 1980). \nSince their discovery many decades ago\, these adaptive perceptual mechanisms have been considered primarily as processes supporting the decoding of ambiguous speech signals originating from other talkers. Here\, I will describe two recent studies demonstrating that such adaptive processes can also alter the processing of self-generated speech acoustic signals (i.e.\, auditory feedback)\, and by extension\, the sensorimotor control of speech production. The results provide strong support for the idea that short-term auditory-perceptual plasticity rapidly transfers to the sensory processes guiding speech motor function. The findings will be discussed within the context of current models of speech production\, in particular those that highlight a role for auditory-feedback in the fine-tuning of predictive\, feed-forward control processes.

SUMMARY:Dissociating Prediction and Attention Components in Language by Ruth de Diego-Balaguer
DESCRIPTION:Dissociating Prediction and Attention Components in Language by Ruth de Diego-Balaguer (ICREA Research Professor – Cognition and Brain Plasticity Unit\, Universitat de Barcelona)\nSpeech is composed of sequences of syllables\, words and phrases. These elements unfold in time in specific orders. Thus\, acquiring a language requires not only learning each of these representations but also their temporal organisation. The areas conforming the dorsal stream in language has been proposed to have a role in the processing of sequential information. In this talk I will present novel behavioural\, developmental and neuroimaging evidence indicating that the roles of the fronto-parietal and fronto temporal connectivity within this dorsal stream can be dissociated in language learning. In addition\, I will present data indicating that learning non-adjacent dependencies in language\, a core mechanism for the acquisition of syntactic rules\, involves both the ability to predict forthcoming elements implicitly and to endogenously orient attention based on the predictive cues learned. This type of learning implies the interface between the language and attention networks during the early stages of language acquisition.

SUMMARY:Learning to take turns : The role of linguistic and interactional cues in children's conversation by Marisa Casillas
DESCRIPTION:Learning to take turns : The role of linguistic and interactional cues in children’s conversation by Marisa Casillas (Max Planck Institute for Psycholinguistics)\nChildren begin taking turns with their caregivers long before their first words emerge. But as their turns begin to change from vocalizations to true\, verbal utterances\, children face a major challenge in integrating linguistic cues into their previously functional non-verbal turn-taking systems. I will present an overview of children's turn-taking behaviors from infancy through young childhood and will review recent corpus and experimental work on how children's response timing is affected by linguistic planning and how their spontaneous predictions about upcoming turns change as they develop.

SUMMARY:Analyzing\, Cognitive\, and Neural Modeling of Language-Related Brain Potentials by Peter Beim Graben
DESCRIPTION:Analyzing\, Cognitive\, and Neural Modeling of Language-Related Brain Potentials by Peter Beim Graben (Bernstein Center for Computational Neuroscience Berlin\, Humboldt-Universität zu Berlin)\nHow is the human language faculty neurally implemented in the brain? What are the neural correlates of linguistic computations? To which extent are neuromorphic cognitive architectures feasible and could they eventually lead to new diagnosis and treatment methods in clinical linguistics (such as linguistic prosthetics)? These questions interfacing neurolinguistics with computational linguistics and computational neuroscience are addressed by the emergent discipline of computational neurolinguistics. In my presentation I will give an overview about my own research in computational neurolinguistics in the framework of language-related brain potentials (ERPs). By means of a paradigmatic ERP experiment for the processing and resolution of local ambiguities in German [1]\, I first introduce a novel method to identifying ERP components such as the P600 as ""recurrence domains"" in neuronal dynamics [2]. In a second step\, I use a neuro-computational approach\, called ""nonlinear dynamical automaton"" NDA [1] in order to construct a context-free ""limited repair parser"" [3] for processing the linguistic stimuli of the study. Finally\, I demonstrate how the time-discrete evolution of the NDA can be embedded into continuous time using winner-less competition in neural population models [4]. This leads to a representation of the automaton's configurations as recurrence domains in the neural network that can be correlated with experimentally measured ERPs through subsequent statistical modeling [5\,6]

SUMMARY:Statistical learning as an individual ability by Ram Frost
DESCRIPTION:Statistical learning as an individual ability by Ram Frost (The Hebrew University of Jerusalem – Department of Psychology)\nMost research in Statistical Learning (SL) has focused on mean success rate of participants in detecting statistical contingencies at a group level. In recent years\, however\, researchers show increased interest in individual abilities in SL. What determines individuals' efficacy in detecting regularities in SL? What does it predict? Is it stable across modalities? We explore these questions by trying to understand the source of variance in performance in a visual SL task through a novel methodology. The theoretical implications for a mechanistic explanation of SL will be discussed.

SUMMARY:How do central processes cascade into peripheral processes in written language production ? by Sonia Kandel
DESCRIPTION:How do central processes cascade into peripheral processes in written language production ? by Sonia Kandel (LPNC & Gipsa-Lab Grenoble (Univ. Grenoble Alpes\, CNRS))\nWith the arrival of internet\, tablets and smartphones many people spend more time writing than speaking (email\, chat\, SMS\, etc.). Despite the importance of writing in our society\, the studies investigating written language production are scarce. In addition\, most studies investigated written production either from a central point of view (i.e.\, spelling processing) or a peripheral approach (i.e.\, motor production) without questioning their relation. We believe\, instead\, that central and peripheral processing cannot be investigated independently. There is a functional interaction between spelling and motor processing. Letter production does not merely depend on its shape –and its specifications for stroke order and direction– but also on the way we encode it orthographically. For example\, the movements to produce letters PAR in the orthographically irregular word PARFUM (perfume) are different than in the regular word PARDON (pardon). Spelling processes cascade into motor production. The nature of the spelling processes that are activated before movement initiation will determine the way the cascade will operate during movement production. Lexical and sub-lexical processes do not spread into motor execution to the same extent.\n

SUMMARY:Apes\, Language and the Brain by Bill Hopkins
DESCRIPTION:Apes\, Language and the Brain by Bill Hopkins (Georgia State University)\nFor more than 150 years\, philosophers and scientist have pondered the uniqueness of human language with a particular fascination with the linguistic\, cognitive and neural capacities of great apes. A majority of the scientific work on this topic has come from so-called ""ape-language"" studies With the advent of modern imaging technologies\, the question of human language uniqueness can now be addressed from a neurological perspective. In this presentation\, I discuss the neurobiology of language from the standpoint of comparative studies on the evolution of Broca's and Werncicke's areas in primates\, notably chimpanzees.

SUMMARY:If you talk to a man in a language he understands\, that goes to his head. If you talk to him in his language\, that goes to his heart by Albert Costa
DESCRIPTION:If you talk to a man in a language he understands\, that goes to his head. If you talk to him in his language\, that goes to his heart by Albert Costa\nWe are constantly making decisions of many different sorts. From more mundane decisions such as which clothes to wear every morning or where to go for lunch\, to more relevant ones\, such as whether we can afford the price of a nice holiday on a Pacific island\, or whether an investment plan is too risky; decision making is an everyday life activity. It is well known that our decisions often depart from a purely rational cost benefit economical analysis\, and that indeed they are biased by several factors that prompt intuitive responses that often drive the decision made. In this talk\, I will describe several studies in which there is a pervasive effect of the language in which problems are presented on decision-making. These studies cover economic\, moral and intellectual decisions. Together the evidence suggests that a reduction in the emotional resonance prompted by the problem leads to a reduction in the impact of intuitive processes on decision-making. This evidence not only helps to understand the forces driving decision-making\, but it also has important implications for a world in which people are commonly faced with problems in a foreign language.

SUMMARY:Gesture as a Window Onto Conceptualization. by Gale Stam
DESCRIPTION:Gesture as a Window Onto Conceptualization by Gale Stam (National Louis University)\nAccording to McNeill (1992\, 2005\, 2012) gestures are as much a part of language as speech is. Together gesture and speech develop from a 'growth point' that has both imagistic and verbal aspects. This model for verbal thought is ""a 'language-imagery' or language-gesture dialectic"" in which thought\, language\, and gesture develop over time and influence each other (McNeill\, 2005 p.25). \nResearch on both the perception of speech and gesture (Kelly\, Kravitz & Hopkins\, 2004) and the production of speech and gesture (Marstaller & Burianová\, 2014) have shown that the same areas of the brain are involved in both. In addition\, empirical research (e.g.\, Chase & Wittman\, 2013; Goldin-Meadow\, Wein\, and Chang\, 1992; Goldin-Meadow & Alibali\, 1995; Iverson & Goldin-Meadow\, 2005; McNeill & Duncan\, 2000; Özçalışkan & Goldin-Meadow\, 2005\, 2009; Stam\, 1998\, 2006\, 2008\, 2010b\, 2014) on co-speech gestures indicates that gestures provide information about speakers' thinking and conceptualizations that speech alone does not. Research on the light gestures can shed on the second language acquisition process and second language teaching has been growing (for reviews\, see Stam 2013; Stam & McCafferty 2008). One area in particular where gestures have been shown to provide an enhanced window onto the mind is that of motion events and thinking for speaking (Stam 2007). This talk will discuss how gestures allow us to see speakers' conceptualizations in first language and second language thinking for speaking. It will present evidence from several studies (Stam\, 2010a\, 2015 ;

SUMMARY:Reverse engineering early language learning by Emmanuel Dupoux
DESCRIPTION:Reverse engineering early language learning by Emmanuel Dupoux by (Ecole des Hautes Etudes en Sciences Sociales\, Laboratoire de Sciences Cognitives et Psycholinguistique)\nDecades of research on early language acquisition have documented how infants quickly and robustly acquire their native tongue(s) across large variations in their input and environment. The mechanisms that enable such a feat remain\, however\, poorly understood. The proposition\, here\, is to supplement experimental investigations by a quantitative approach based on tools from machine learning and language technologies\, applied to corpora of infant directed input. I illustrate the power of this approach through a reanalysis of some previous claims made regarding the nature and function of Infant Directed as opposed to Adult Directed Speech (IDS vs ADS). I also revisit current ideas about the learning of phoneme categories\, a problem that has been long thought to involve only bottom-up statistical learning. In contrast\, I show that a bottom up strategy does not scale up to real speech input\, and that phoneme learning requires not only the joint learning of phoneme and word forms but also of prosodic and semantic representations. I discuss a global learning architecture where provisional linguistic representations are gradually learned in parallel\, and present some predictions for language learning in infants.\n

SUMMARY:Do inhibit or not to inhibit during bilingual language control by Mathieu Declerck
DESCRIPTION:Do inhibit or not to inhibit during bilingual language control by Mathieu Declerck (BLRI\, AMU)\nOne of the mayor topics in the language control literature specifically\, and the bilingual literature in general is inhibition\, which entails the reduction of non-target language activation and thus interference resolution. In this talk I would discuss the existing evidence for inhibitory control processes at work during language switching\, a commonly used task to investigate the underlying mechanism of language control. More specifically\, asymmetrical switch costs\, n-2 language repetition costs\, and reversed language proficiency in mixed language blocks will be discussed in relation to inhibition. Finally\, since several models assume little to no implementation of inhibition with highly proficient bilinguals\, the role of language proficiency will also be considered.

SUMMARY:Do visual and attentional factors predict reading skills? by Veronica Montani
DESCRIPTION:Do visual and attentional factors predict reading skills? by Veronica Montani (BLRI\, AMU)\nVisual-attentional abilities have a prominent role in reading. Reading rate is constrained by the number of letters acquired at each fixation\, i.e. the visual span\, that in turn seems to be mainly determined by the effect of crowding. On the other hand\, spatial attention is critically involved in reading process\, in particular for the phonological decoding of unfamiliar strings. I will briefly review studies that investigated the role of low-level processing factors in reading and their possible implication in reading disorders. Furthermore\, I will present new data that show the distinct contribution of different visual-attentional factors on various reading measures\, such as text reading\, word naming and eye movements.

SUMMARY:Probabilistic Graphical Models of Dyslexia by Yaïr LAKRETZ
DESCRIPTION:Probabilistic Graphical Models of Dyslexia by Yaïr LAKRETZ (‘Sagol’ school of neuroscience\, Tel-Aviv University)\nReading is a complex cognitive faculty\, errors in which assume diverse forms. To capture the complex structure of reading errors\, we propose a novel way of analyzing these errors using probabilistic graphical models. Our study focuses on three inquiries. (a) We examine which graphical model best captures the hidden structure of reading errors. (b) We draw on the results of (a) to resolve a theoretical debate on whether dyslexia is a monolithic or heterogeneous disorder. (c) We examine whether a graphical model can diagnose dyslexia closely to how experts do. We explore three different models: an LDA-based model and two Naïve Bayes models which differ by their assumptions about the generation process of reading errors. The models are trained on a large corpus of reading errors. Our results show that the LDA-based model best captures patterns of reading errors and may therefore contribute to the understanding of dyslexia and to the diagnostic procedure. We also demonstrate that patterns of reading errors are best described by a model assuming multiple dyslexia subtypes\, therefore supporting the heterogeneous approach to dyslexia. Finally\, a Naïve Bayes model\, which shares assumptions with diagnostic practice\, best replicates labels given by clinicians and can be therefore used for automation of the diagnosis process.

SUMMARY:The influence of expertise on perception\, cognition\, and brain connectivity by Stefan Elmer
DESCRIPTION:The influence of expertise on perception\, cognition\, and brain connectivity by Stefan Elmer (Universität Zürich)\nA better understanding of the perceptual and cognitive neural underpinnings underlying exceptional behavioural skills has important educational\, societal\, as well as clinical implications (i.e.\, for example in the context of developmental dyslexia\, aphasia\, and foreign language learning). Here\, I will present recent data collected from professional musicians with and without absolute pitch\, as well as from simultaneous language interpreters\, to reveal how expertise and training has an influence on the functional-structural malleability of perceptual and cognitive subdivisions of the human brain. In the same context\, I will also provide some evidence for transfer effects from musicianship to specific aspects of speech processing. Finally\, since currently there is no doubt that perceptual and cognitive functions do not work in isolation but are embedded in neuronal assemblies consisting of networks influencing each other's in a reciprocal manner\, I will propose some novel methodological approaches for evaluating functional and structural connectivity within small-scale perceptual-cognitive networks in musicians with and without absolute pitch.

SUMMARY:Towards an Online Rhyming Dictionary for Mexican Spanish by Alfonso Medina
DESCRIPTION:Towards an Online Rhyming Dictionary for Mexican Spanish by Alfonso Medina\nRhyming dictionaries are a kind of reverse dictionaries. They group words according to rhyming patterns. Rhymes can share exact sequences of vowel and consonant sounds towards the end of a word (consonant rhyme) or just similar vowel sounds (assonant rhyme). Thus\, these dictionaries are based on pronunciation\, not on writing patterns. Also\, since consonance and assonance depend on the stressed syllable\, words which end with a stressed syllable are grouped together\, those whose stressed syllable is the next to last appear together\, and so on.\n\nIn addition\, word pronunciation may vary with time and across geographical and social dialects. In Spanish\, this is particularly clear when word loans (for instance\, Anglicisms and Galicisms) are considered. In fact\, they tend to keep their original writing\, at least in the Mexican variant which is the most spoken one. For example\, the following loan words\, common in Mexican Spanish\, rhyme: flash\, collage\, garage\, cottage\, squash. Their last syllable is stressed and they are ordered in reverse according to their sounds and not their letters: (respectively\, /fláʃ/\, /ko.láʃ/\, /ga.ráʃ/\, /ko.táʃ/ and /es.kwáʃ/).\n\nThe project described takes the current nomenclature of the Diccionario del español de México (http://dem.colmex.mx/) to generate automatically a rhyming dictionary. Also\, since the results of an online query to such a dictionary can be quite large\, a procedure was developed to rank them semantically. The idea is to measure the similarities of the query definition to each of the definitions of the rhyming words. These words are then ordered from highest to lowest similarity to the query.

SUMMARY:The bilingual brain: Plasticity and processing from cradle to grave by Manuel Carreira
DESCRIPTION:The bilingual brain: Plasticity and processing from cradle to grave by Manuel Carreira (Basque Center on Cognition\, Brain and Language\, Donostia-San Sebastian\, Spain IKERBASQUE. Basque Foundation for Science. Bilbao. Spain)\nMost people either learn more than one language from birth or invest quite a lot of time and effort learning a second language. Bilingualism and second language learning is an interesting case for investigating cognitive and brain plasticity. In this talk I will describe behavioral and neuroimaging evidence on the cognitive and brain mechanisms adults and infants (monlinguals\, bilinguals and second language learners) use for processing language. In particular I will address whether proficient second language learners use similar or different brain mechanisms during processing and what are the neural consequences (structural and functional) of dealing with two languages.

SUMMARY:How do central processes cascade into peripheral processes in written language production? by Sonia Kandel
DESCRIPTION:How do central processes cascade into peripheral processes in written language production? by Sonia Kandel (Univ. Grenoble Alpes\, LPNC (CNRS UMR 5105) – Grenoble\, France And Univ. Grenoble Alpes\, GIPSA-LAB (CNRS UMR 5216)\, Dept. Parole & Cognition –Grenoble\, France)\nWith the arrival of internet\, tablets and smartphones many people spend more time writing than speaking (email\, chat\, SMS\, etc.). Despite the importance of writing in our society\, the studies investigating written language production are scarce. In addition\, most studies investigated written production either from a central point of view (i.e.\, spelling processing) or a peripheral approach (i.e.\, motor production) without questioning their relation. We believe\, instead\, that central and peripheral processing cannot be investigated independently. There is a functional interaction between spelling and motor processing. Letter production does not merely depend on its shape –and its specifications for stroke order and direction– but also on the way we encode it orthographically. For example\, the movements to produce letters PAR in the orthographically irregular word PARFUM (perfume) are different than in the regular word PARDON (pardon). Spelling processes cascade into motor production. The nature of the spelling processes that are activated before movement initiation will determine the way the cascade will operate during movement production. Lexical and sub-lexical processes do not spread into motor execution to the same extent.

B 5 avenue Pasteur\, Aix-en-Provence\n9h30-12h30 Salle de conférences B011\, bât. B 5 avenue Pasteur\, Aix-en-Provence\n\nCross-linguistic and neurolinguistic perspectives on reading and speech processing\n\nNeural specialization and reading ability \nFan Cao (Michigan State University) \n\nThe brain becomes specialized with exposure to the environment. One piece of evidence comes from how the language system shapes brain function. In a cross-linguistic developmental study\, we show growing divergence between Chinese reading and English reading from children to adults. We found that specialization is positively correlated with proficiency. For example\, there is reduced specialization in children with reading disability. Another example is proficiency effect in bilinguals\, where we found greater specialization with higher proficiency in a group of late Chinese-English bilinguals. We also found that specialization can be facilitated by providing more effective instruction. In a series of training studies\, we compared writing and visual-only learning in English learners of Chinese\, and we found writing training evoked a more native-like brain network\, suggesting greater specialization and accommodation. In summary\, the brain becomes specialized with language experience and optimal instruction will promote the process of specialization.\n\nHow does learning to read modify speech processing ? Chotiga Pattamadilok (Laboratoire Parole et Langage) \n\nBehavioral and brain imaging studies have demonstrated that learning to read and write changes the way the brain processes spoken language. However\, the cognitive and neural mechanisms underlying such modification are still under debate. Two complementary hypotheses have been proposed. According to the ""online"" account\, strong connections between spoken and written language result in the automatic co-activation of both codes when one processes language\, such that hearing a spoken word activates\, in real time\, its corresponding written form and vice-versa. According to the ""offline or developmental account"" learning to read induces more profound changes withinthe spoken language system itself\, probably by restructuring the nature of the phonological representations. Evidence supporting both hypotheses will be discussed.\n\nA cross-language perspective on reading\, reading development and dyslexia Johannes Ziegler (Laboratoire de Psychologie Cognitive) \n\nMany theories assume that different languages or writing systems afford different reading styles. One idea that has been around since the early 70s is that opaque writing systems favor a ""Chinese"" style of reading (a direct route to meaning) whereas transparent writing systems favor a ""Phoenician"" style (an indirect route that is phonologically mediated). However\, research on reading development and dyslexia across languages draws a different picture\, one in which the core reading processes are very similar across languages. The main differences are related to consistency and orthographic complexity – these variables affect the granularity of the computations rather than the computations themselves.

SUMMARY:Neuroanatomical correlates of developmental dyslexia by Irène Altarelli
DESCRIPTION:Neuroanatomical correlates of developmental dyslexia by Irène Altarelli (Brain and Learning Lab.\, University of Geneva)\nDevelopmental dyslexia is a specific learning disorder that impacts reading abilities\, despite normal education\, intelligence and perception. The aim of the present work is to determine its neuroanatomical correlates\, with the broader goal of identifying associations between genetic variants\, brain anatomy and cognitive impairments. To this end\, three studies were conducted\, comparing magnetic resonance images of dyslexic and control subjects. In a first study\, we analysed a variety of cortical measures with both a region of interest and a global vertex-by-vertex approach. In a second study\, we focused on the ventral temporo-occipital regions\, looking at the structure of functionally defined areas. We defined the subject-by-subject location of cortical regions preferentially responding to written words\, faces or houses. A cortical thickness reduction in dyslexic subjects was observed in the left-hemisphere word-responsive region\, an effect exclusively driven by dyslexic girls. Finally\, in a third study we examined the anatomical asymmetry of the planum temporale\, a region which importance in dyslexia has been widely debated. By manually labelling this structure\, we observed an abnormal pattern of asymmetry in dyslexic boys only. To conclude\, a number of anatomical correlates of dyslexia have emerged from the work presented here\, offering a better characterisation of its brain basis.Importantly\, our results also stress the importance of gender\, a long neglected factor in dyslexia

SUMMARY:Prosodic and Social Dimensions of Entrainment in Dialogue by Julia Hirschberg
DESCRIPTION:Prosodic and Social Dimensions of Entrainment in Dialogue by  (Columbia University)\nWhen people speak together\, they often adapt aspects of their speaking style based upon the style of their conversational partner. This phenomena goes by many names\, including adaptation\, alignment\, and entrainment\, inter alia. In this talk\, I will describe experiments in English and Mandarin prosodic entrainment in the Columbia Games Corpus and in the Tongji Games Corpus\, large corpora of speech recorded from subjects playing a series of computer games. I will discuss how prosodic entrainment is related to turn-taking behaviors and to several measures of task and dialogue success. I will also discuss experiments relating entrainment to several social dimensions\, including likeability and dominance. This is joint work with Stefan Benus\, Agustín Gravano\, Ani Nenkova\, Rivka Levitan\, Laura Willson\, and Zhihua Xia.

SUMMARY:A Vocal Brain: Cerebral Processing of Voice Information by Pascal Belin
DESCRIPTION:A Vocal Brain: Cerebral Processing of Voice Information  (Institut des Neurosciences de La Timone\, Marseille\, France)\nThe human voice carries speech but also a wealth of socially-relevant\, speaker-related information. Listeners routinely perceive precious information on the speaker's identity (gender\, age)\, affective state (happy\, scared)\, as well as more subtle cues on perceived personality traits (attractiveness\, dominance\, etc.)\, strongly influencing social interactions. Using voice psychoacoustics and neuroimaging techniques\, we examine the cerebral processing of person-related information in perceptual and neural voice representations. Results indicate a cerebral architecture of voice cognition sharing many similarities with the cerebral organization of face processing\, with the main types of information in voices (identity\, affect\, speech) processed in interacting\, but partly dissociable functional pathways.

SUMMARY:La Poesie des synapses ou comment les mots nous font plaisir ou peur ? by Arthur Jacobs
DESCRIPTION:La Poesie des synapses ou comment les mots nous font plaisir ou peur ? by Arthur Jacobs (Freie Universität Berlin\, Dahlem Institute for Neuroimaging of Emotion (D.I.N.E.))\nLa lecture n'est pas seulement un processus de traitement d'information\, mais elle comporte des réponses affectives et esthétiques qui vont bien au-delà de ce que les modèles actuels de la lecture décrivent. Des mots peuvent nous plaire ou faire mal\, des textes nous rendre heureux ou faire pleurer. Mais comment des stimuli ""symboliques"" peuvent-ils évoquer des réponses émotionelles? Quels sont les processus neurocognitifs qui les sous-tendent\, et comment les réactions émotionelles à des narrations fictives se distinguent-elles de celles à des narrations factuelles? Dans ce séminaire\, j'aborde ces questions dans le cadre d'un modèle neuropoétique de la lecture littéraire qui intègre des éléments de rhétorique\, d'esthétique et de poétique cognitive avec des concepts de neurolinguistique et de psychonarrotologie (Jacobs\, 2011; 2013). Ces prédictions sont discutées à la lumière des données venant d'études empiriques sur la reconnaissance des mots\, la réception de la poésie\, et de la compréhension des phrases et textes.

SUMMARY:Apprentissage par renforcement (direct et inverse) pour les systèmes interactifs by Olivier Pietquin
DESCRIPTION:Apprentissage par renforcement (direct et inverse) pour les systèmes interactifs by Olivier Pietquin (SequeL team\, University Lille 1\, LIFL CNRS UMR 8022\, INRIA Lille)\nL'apprentissage par renforcement est une catégorie d'apprentissage automatique qui se différencie des autres par le fait qu'elle a pour objectif l'optimisation d'une séquence de décisions\, prenant en compte l'aspect temporel et surtout dirigé par un but du comportement. Cette méthode\, d'inspiration biologique\, est fondée sur l'accumulation par la machine de récompenses numériques distribuées après chaque décision. Le comportement appris est celui qui maximise\, sur le long terme\, l'accumulation de récompenses\, menant à une séquence de décisions optimale. Ce paradigme d'apprentissage a été introduit dans le domaine des systèmes de dialogue parlé il y a une quinzaine d'année afin d'optimiser les stratégies d'interaction. En effet\, ce type de système doit prendre des décisions sur les actes dialogiques à produire à chaque tour d'interaction avec un utilisateur. Ces décisions doivent mener à une interaction la plus naturelle et efficace possible alors que les informations recueillies sont entachées d'erreurs (due à la reconnaissance et la compréhension imparfaites du langage parlé). Il est difficile de définir formellement ce que serait une interaction parfaite\, en revanche un utilisateur peut fournir une évaluation a posteriori de cette interaction servant de signal de récompense. Toutefois\, un certain nombre de problèmes subsistent encore aujourd'hui pour faire un usage performant de ces méthodes dans le cadre de l'interaction homme-machine. Un de ces problèmes est la définition de la récompense à fournir à la machine pour la voir se comporter de manière naturelle. En effet\, l'utilisation de la satisfaction de l'utilisateur a montré quelques limites et est difficile à prédire automatiquement. Dans cet exposé\, nous présenterons le paradigme de l'apprentissage par renforcement inverse\, visant à estimer la fonction de récompense optimisée par un opérateur humain (supposé optimal) et à la transférer à la machine pour obtenir un comportement similaire dans une tâche d'interaction.
