Jaeger (linguistics, U. of Buffalo, The State U. of New York) presents the first developmental linguistics research volume documenting how on-line processing is revealed in young children, ages 18 months through five years, through their slips of the tongue (SOTs). Coverage includes an overview of SOTs in linguistic research, a detailed description of the model of speech production planning developed by Jaeger for the study, a comparison of children's SOTs to adult errors, and detailed analysis of the study's results in the areas of phonological representations and processing, the lexicon and lexical errors, semantic relationships in lexical errors, and morphology and syntax. All of the child data is included both in the book and on a website hosted by the author, which also includes the adult data. No subject index.
