This paper explores young children’s and parents’ use of color words and animal names in two published studies. The aim is to compare the ranges and kinds of these words in parentchild interaction and to consider the implications of these findings for our understanding of early lexical development. Color term data were drawn from the Gleason corpus in CHILDES: 12 boys and 12 girls ranging in age from 25-62 months, and their parents. Results showed that parents used and emphasized only the same 10 most basic colors, with many teaching episodes. Parents’ most frequent terms, red, blue, and green were also children’s most frequent terms and are the ones acquired earliest according to MacArthur Bates lexical norms. In the second study CLAN programs were used to identify animal names in corpora from a variety of families in CHILDES, with 44 children ranging in age from 1;6-6;2. Children and parents produced a remarkable number and range of animal terms, with individual preschoolers naming as many as 96 different, often rare, animals, such as crocodile and pelican. Parents and children thus attend to the same limited set of basic color terms. By contrast, biophilia, our shared human love of the living world is reflected in children’s extensive animal lexicon.

The goal of the present study was to characterize how neighborhood structure in sign language influences lexical sign acquisition in order to extend our understanding of how the lexicon influences lexical acquisition in both sign and spoken languages. A referentmatching lexical sign learning paradigm was administered to a group of 29 hearing sign language learners in order to create a sign lexicon. The lexicon was constructed based on exposures to signs that resided in either sparse or dense handshape and location neighborhoods. The results of the current study indicated that during the creation of the lexicon signs that resided in sparse neighborhoods were learned better than signs that resided in dense neighborhoods. This pattern of results is similar to what is seen in child first language acquisition of spoken language. Therefore, despite differences in child first language and adult second language acquisition, these results contribute to a growing body of literature that implicates the phonological features that structure of the lexicon is influential in initial stages of lexical acquisition for both spoken and sign languages. This is the first study that uses an innovated lexicon-construction methodology to explore interactions between phonology and the lexicon in L2 acquisition of sign language.
