From prelinguistic communication to word use in typically hearing and deaf infants

The involvement of left ventral occipitotemporal cortex in speech processing

Shuai Wang, Postdoc ILCB/LPL

Abstract:
The left ventral occipitotemporal cortex, also named visual word form area, plays a key role in reading. Recent evidence suggests that it is also involved in different levels of speech processing, from phoneme analysis to sentence listening. Yet, little is known about the underlying mechanisms of this cross-modal activation and the communication between this area and the spoken language system. In this talk, we are going to introduce our on-going research that addresses these issues from a network perspective by 1) applying the Graph Theory on fMRI data, and 2) examining the temporal dynamics of the communication between areas within the spoken and written language system using an intracranial EEG protocol.

What we learn and when we learn it: the interaction of maturation and experience in music and language

The impact of training or experience is not the same at all points in development. Children who learn to play a musical instrument or speak a second language early in life are often more proficient as adults. In the domain of music, a wealth of anecdotal evidence suggests that early training is important for musical skill, however, there has been little evidence directly demonstrating the impact of the age of start. To address this question, work in my laboratory has compared behavior and brain structure in early- (<7) and late-trained ( >7) adult and child musicians, showing differences in behavior and brain structure. More recently, we have compared early- and late-trained musicians with simultaneous and sequential bilinguals, showing differential effects of age-of-start in the arcuate fasciculus. I will discuss these findings in the context of our understanding of the interaction between normative development and specific experience, and describe a model of gene-environment interactions that integrates the contribution of age of start.

Using Data Science to Study Children’s Cognitive Development

Abdellah Fourtassi

Following the seminal work of Piaget, the traditional approach in cognitive development has focused on studying the structure of children’s knowledge in controlled situations (e.g., laboratory experiments). While this approach allows for precise inference about how children behave in certain tasks, it cannot provide an understanding of the social context within which knowledge emerges. In fact, it has been known, at least since Vygotsky, that children acquire new skills and concepts with the help of more competent members of society who scaffold the children’s learning, allowing them to attain skills that are just beyond their current abilities. In fact, much of the children’s abstract knowledge about the world, it has been argued, is mediated through discussions with their parents/caregivers.

In this talk, I explain how new advances in Data Science, especially in Natural Language Processing (NLP), allow us to 1) account for what and how information is presented to children by their parents through language, and 2) make precise predictions about the way this information can be used by children in controlled designs. Thus, NLP can create a fruitful synergy between controlled and naturalistic research methods. More generally, I argue that a complete theory of cognitive development requires interdisciplinary research across computer science and psychology.
