Накратко на български

Развитието на речта при бебета и плътоядни гризачи се анализира чрез разликата в обработката на съгласните и гласните звуци. Това помага да се разбере как се усвоява езикът и как да се разпознаят ранни забавяния в развитието на децата.

Speech-sound Processing in Infant Development and Evolution

• What is the problem/issue being addressed? Speech is composed of two categories of sound, i.e. consonants and vowels, which have different properties and serve different linguistic functions. This consonant/vowel asymmetry, which is established in adults, has led to the hypothesis of a division of labor between consonants and vowels present early in infancy would whereby facilitate lexical acquisition thanks to a specific targeting of consonants (i.e. the Consonant bias), thus to acquire language. • Why is it important for society? It is of major importance to science and society to understand how the ability to learn language arises in our children. In addition this research project comprises a significant impact for applied research on impaired language development (e.g. identifying the early signs of speech sound processing delays in babies) and language education (e.g. how exposure to more than one language might impact the use of consonants and vowels). • What are the overall objectives? First, we have explored the developmental validity of this hypothesis by studying its origins and emergence in Spanish infants during the course of the first year (infant studies 1 -3) ; second, we have investigated its evolutionary origins in a non-human animal capable of fine speech processing: Long Evans rats (Rattus Norvegicus; animal study 4).

Цел на проекта

What are the uniquely human mechanisms of language acquisition that enable infants to start discovering the words and structures of their native language by the end of their first year? Language is undoubtedly a specifically human function, but it is crucial to disentangle between human-specific vs. general-processing skills that allow language acquisition. This project aims at exploring the developmental and evolutionary origins of one of the features of speech processing: the ability to assign specific functional roles to the different categories of sounds composing speech. Indeed, there is a Consonant/Vowel functional asymmetry in the world's languages as well as in speech processing, whereby consonants better fit the requirements of lexical processing (e.g. when writing abbreviations we tend to remove vowels and keep consonants to avoid compromising meaning, as in txt msgng), while vowels are better targets for syntax-related processes. It remains unknown where this ""division of labour"" comes from: uniquely human predisposition playing a role in early syntax and lexical acquisition, or consequence of the asymmetry present in the input? In this work we will conduct experiments in infants as well as in rats, to test the hypothesis that the C/V asymmetry : (1) is not the by-product of the physical differences between vowels and consonants, (2) plays a significant role in early language acquisition; (3) derives from more general perceptual biases shared with other species. This interdisciplinary project will use both behavioral and neuroimaging measures in infants and rats to investigate the origins of the C/V asymmetry in language acquisition and evolution.""
