Categorical perception (CP) is likely the single finding from speech perception with the
biggest impact on cognitive science. However, within speech perception, it is widely known …

An early achievement in language is carving a variable acoustic space into categories. The
canonical story is that infants accomplish this by the second year, when only unsupervised …

In the first decades of the 21st century, exemplar theory has fueled an explosion of
theoretical and empirical work in speech production. We review the foundations for this …

Before they even speak, infants become attuned to the sounds of the language (s) they hear,
processing native phonetic contrasts more easily than nonnative ones. For example …

At birth, infants discriminate most of the sounds of the world's languages, but by age 1,
infants become language-specific listeners. This has generally been taken as evidence that …

Infants learn their native language (s) at an amazing speed. Before they even talk, their
perception adapts to the language (s) they hear. However, the mechanisms responsible for …

Before they even produce their first word, infants start develo** a language-specific
perception, recognize the auditory form of frequent words, and develop a rudimentary …

In the first year of life, infants' speech perception becomes attuned to the sounds of their
native language. This process of early phonetic learning has traditionally been framed as …

Most current theories and models of second language speech perception are grounded in
the notion that learners acquire speech sound categories in their target language. In this …

There is a current 'theory crisis' in language acquisition research, resulting from
fragmentation both at the level of the approaches and the linguistic level studied. We identify …
