The proceedings of this Georgetown University Round Table on developmental psycholinguistics are divided into four sections: (1) "Children's Language Acquisition: Linguistic and Psycholinguistic Theory"; (2) "Children's Language Acquisition and Communicative Disorders"; (3) "Developmental Psycholinguistics and Second Language Learning"; and (4) "Developmental Psycholinguistics and Education." The papers in the first section deal with sound patterns, speech, psychologically real grammar, and the acquisition of meaning. The second panel deals with the acquisition of transformations, children's language problems, and postsemantic processes in delayed child language related to first and second language learning. The panel on developmental psycholinguistics and second language learning treats cerebral dominance and language learning, second language learning, approaches to discovering universal strategies of child second language acquisition, and psycholinguistic universals in children's learning of Spanish. The fourth section treats Piagetian equilibration processes in syntax learning, the acquisition of knowledge by children educated bilingually, class inclusion, and men's speech to young children.
