Since general principles of first language acquisition and environmental input have been clarified by research of the last decade, more differentiated questions are explored in the present study. The main goal is the investigation of similarities and differences in the language teaching and learning processes involved in the verbal interactions…

Brown's (1979) assertion that frequency of input is not a significant variable in language acquisition was evaluated through a reanalysis of Brown's data. Frequency of parental speech input was found to be highly related to frequency of production. (Author/AM)

Analyzes language teaching and learning as it transpires during the course of verbal interaction in the home. (DF)

Two children were observed for half a year and specific topics were examined in child communication: how much information is transmitted through various channels of verbal and nonverbal communication? Is specific information transmitted through specific channels? Can relationships between the channels be expressed through some type of formula?…

The behavior of a preverbal infant was analyzed in a search for orderly and systematic patterns. Basic elements of the infant's repertoire were distinguished. A comparison was made between the nonverbal and those verbal structures which appear early. (Author/RM)

This paper examines whether language development can be understood epigenetically in the same manner and based on the same principles with which Piaget has analyzed intellectual-cognitive development generally. The study is subdivided into four parts: (1) some principles in Piaget's system (the epigenetic principle, the genetic circle, and the…

This book provides a summary of past and cutting-edge research on the acquisition of language by young children. It lends support to the behavioralist paradigm of language acquisition, namely, that maternal rewards and corrections should be integrated with perceptual, cognitive, and social learning conceptualizations in a skill-learning approach…
