RESEARCH PROJECTS IN PROGRESS AT THE UNIVERSITY OF MICHIGAN'S CENTER FOR RESEARCH ON LANGUAGE AND LANGUAGE BEHAVIOR ARE OUTLINED IN THIS REPORT. EACH PROJECT DESCRIPTION INCLUDES A BRIEF SUMMARY OF THE PURPOSES, SCOPE, AND DESIGN OF THE RESEARCH, AS WELL AS AN ACCOUNT OF THE WORK ACTUALLY UNDERWAY. THE NAMES OF THE PRINCIPAL INVESTIGATORS ARE ALSO…

Children identified as late talkers at 20-34 months of age were followed yearly throughout the preschool period. Data suggest that the longer a language delay persists, the less the chance of spontaneous recovery during the preschool period. Late-talking girls had less chance for spontaneous recovery than did late-talking boys. (Author/JDD)

Reviews research to date dealing with attempts to conceptualize a framework for analysis of communication skills acquired in early childhood years. (MH)

THE RELATIONSHIP OF EDUCABLE MENTAL RETARDATES IN REGULAR CLASSES AND SPECIAL CLASSES WITH RESPECT TO VOCABULARY WAS STUDIED. THERE WERE 49 SUBJECTS TAKEN FROM REGULAR CLASSES AND 45 FROM SPECIAL CLASSES. THE PRIMARY AND ELEMENTARY FORMS OF THE WORD MEANING SECTION OF THE STANFORD ACHIEVEMENT TESTS WERE ADMINISTERED TO EACH SUBJECT BY FOUR PERSONS…

Explores the relations between temperament, communicative competence, and humor expression among four- and five-year-old nursery school children. Shows that ratings of communicative competence and various dimensions of temperament account for a significant proportion of the variance in the reported frequency of children's laughter and verbal and…

Infant's crying may have an important mediating role in the formation of attachment behavior. The earliest vocalizations are discussed in terms of an acoustic communications model in which the baby's vocal repertoire becomes incorporated into a closed-loop, feedback system with his mother. Certain pre-lingual "signals" may be associated with those…

Imitation in the speech of the child serves at least three functions in the development of linguistic competence. Imitation provides auditory feedback for phonological and morpho-syntactic accuracy, produces a model for verification and/or clarification by speakers, and "makes time" for the processing and acquisition of information. Beyond these…

Home and family conditions were found to have an effect on verbal interaction patterns between mothers and persons in the home. (Authors)

Patterns of teacher and student verbal behavior within a framework of reinforcement theory were analyzed through the use of a modified form of the Observation Schedule and Record 4V (OScAR). The study examined the extent to which the rewarding teacher's classroom discourse served as a model for the verbal style of a student among his peers. Data…

Directed both to parents and to professionals, the manual explains factors involved in normal and abnormal language development. Language disorders are discussed, and methods and sources of help are described. (JD)

This paper offers some ideas on the types of behavior that can be considered precursors to language and that also lay the foundations for logic, mathematics, physics, etc. The paper posits the problem of whether a theory of language must be formulated before one can formulate a theory of language acquisition, or whether the reverse is true. The…
