When the B. F. Skinner Foundation reprinted Skinner's "Verbal Behavior" in 1992, Jack Michael wrote one of its two forewords, a detailed outline of the book's purpose and scope. On the 60th anniversary of the first publication (1957) of "Verbal Behavior", Jack reflects on the book's impact and its importance to the…

This study aimed at investigating the similarities and differences between Vygotsky's perspectives on child language development with nativism and behaviorism. Proposing the idea of the Zone of Proximal Development, Vygotsky emphasized the role of collaborative interaction, scaffolding, and guided participation in language learning. Nativists, on…

Discussed is the language impairment of children with infantile autism. The speech patterns of autistic children, including echolalia, pronomial reversal, silent language, and voice imitation, are described. The clinical picture of the autistic child is compared to that of children with such other disorders as deafness, retardation, and…

THE STUDY INVESTIGATED SOME OF THE RELATIONSHIPS BETWEEN A CHILD'S VERBAL BEHAVIOR AND ENVIRONMENTAL EVENTS NECESSARY IN ACQUIRING LANGUAGE. TWO TRAINABLE RETARDATES (FROM A GROUP OF SIX, AGED 3-6 TO 5) WITH A FUNCTIONAL VOCABULARY OF NO MORE THAN TWO OR THREE WORDS WERE SEEN INDIVIDUALLY IN 20- TO 30-MINUTE SESSIONS TWICE A WEEK DURING A 4-MONTH…

A series of three experiments was conducted with three severely retarded children to investigate the vocalization-producing potential of two antecedent conditions: adult talk (commonly cited antecedent) and adult silence. (Author/CL)

Cultural deprivation has been found to affect the acquisition, development, and utilization of language for the child. The influences of environmental variables on language patterns are discussed as a series of conditioned responses reinforced in the developmental process. (Author)

The paper provides an overview of a prelanguage program that was developed for a low functioning, 7 1/2-year-old congenitally deaf-blind child. It is explained that the program was based on principles and procedures as they related to operant behaviors, that reinforcement techniques were continually applied, and that a great deal of successive…

The mothers and fathers of 11 preschool autistic children were taught operant procedures used in teaching speech to nonverbal children. At posttreatment, the children showed significant gains in pre-speech and speech skills as measured by a 21-step hierarchy of speech behaviors. (Author)

This critical review examines 10 controlled studies in which traditional operant behavioral procedures were compared with normalized interventions for teaching language to young children with autism. It concluded that normalized language training was substantially more effective than discrete-trial training and yielded more positive parental…

The author reviews studies in which operant training techniques were used to develop and remediate the speech and language skills of vocal imitation, functional speech, generative speech, and generalized speech usage in autistic, severely retarded, echolalic, and other nonverbal Ss. (LC)

A highly structured language instruction program was used for 4 months to accelerate the verbal development of 10 Down's syndrome children 4- to 7-years-old. (DB)
