Temario

Part I

The goal of this course is to understand how young infants (between 0 to 24 months) crack the speech code and begin to acquire their native language(s). We will discuss how domain-general learning mechanisms that are already present during the first few months of life (e.g., distributional, categorical, or statistical learning) interact with the acquisition of different linguistic levels (e.g., learning phonetic categories, words, syntax). In addition, we will cover the roles of innate auditory biases, such as sensitivity to linguistic and non-linguistic rhythms during acquisition. Further, we will consider the interaction between functional/structural brain maturation and language development in the first two years of life. Throughout the class, a special focus will be given to bilingual first language acquisition, in addition to monolingual acquisition. Moreover, we will focus on the process of the second language acquisition and phonological development in second language acquisition.

Part II

This course aims to describe the processes involved in recognising words in normal-hearing, adult listeners. In the first part of the course, we look at articulatory and acoustic-phonetic representations of the speech signal, on go on to examine the transformations of speech that occur up to the level of the auditory nerve. The second part investigates the link between sounds and words, presents recent computational models of spoken word recognition, and addressing the challenge of variability. In the final part we look at speech pereption in everyday 'non-ideal' conditions.
