Emerging preoccupations, developing lexicon

Developing lexicon and phonetic category acquisition 1 Running head: DEVELOPING LEXICON AND PHONETIC CATEGORY ACQUISITION A role for the developing lexicon in phonetic category acquisition

Infants segment words from fluent speech during the same period when they are learning phonetic categories, yet accounts of phonetic category acquisition typically ignore information about the words in which sounds appear. We use a Bayesian model to illustrate how feedback from segmented words might constrain phonetic category learning by providing information about which sounds occur together ...

Developing a Generative Lexicon Within HPSG

Traditionally NLP systems are syntactically centered and tend to use semantics as a complement to syntactic analyses in cases that cannot be handled by syntax alone. It is true that most theoretically oriented approaches to syntax in NLP introduce an abstract level of representation which they label as semantic. This level, however, can hardly be called semantic, if the information that is repr...

Homonymy in the Developing Mental Lexicon

Fast mapping skills in the developing lexicon.

PURPOSE This preliminary investigation was a longitudinal study of fast mapping skills in normally developing children, 16-18 months of age. The purpose was to examine the effects of practice on the accessibility of words in lexical memory. METHOD Eight children were taught the names of 24 unfamiliar objects over 12 weekly training sessions. The amount of practice children had with individual...

Phonological neighbourhoods in the developing lexicon.

Structural analyses of developing lexicons have provided evidence for both children's holistic lexical representations and sensitivity to phonetic segments. In the present investigation, neighbourhood analyses of two children's (age 3;6) expressive lexicons, maternal input, and an adult lexicon were conducted. In addition to raw counts and frequency-weighted counts, neighbourhood size was calcu...
