We provide an empirically updated Skinnerian-based account of verbal behavior development, describing how the speaker-as-own-listener capability in children (the capability of children to behave as speaker and listener within their own skin) accrues and how it is pivotal to becoming verbal. The theory grew from (a) findings in experiments with…

Among 128 girls attending a private day school in Australia, it was found that changes in semantic aspects of language which occur at the formal operational stage appear to be related to whether a child is classified at the formal operational level on a pendulum problem. (RH)

It is suggested that because of the tendency of psychologists to characterize behavioral phenomena in distinctive ways, it is frequently difficult to determine if the same label is being used to refer to the same phenomenon by different investigators. One strategy to overcome this problem is to determine if similar conclusions are reached when the…

This study attempted to test the notion that the reinforcing stimuli which maintain high rates of speech may not consist solely of events extrinsic to the person but may involve (sensory) stimulation generated by the behavior itself. (Author)

Examines whether novelty produces more or less attention than familiarity and incongruity, and whether children's learning behavior is related to these differences in attention. Subjects were 43 three- to five-year-old children. (BD)

The verbal interactions of 20 mothers with their children, who were between 1.9 and 5.0 years old, were recorded and analyzed. (SB)

This paper, one in a series investigating day care services, is based on two assumptions concerning verbalizations of preschool children: (1) the complexity of verbalizations is more important than the quantity; and (2) the quality of care is directly related to the occurrence of the complexity of verbalizations. The higher the occurrence of…

In order to test the hypothesis that the ability to form verbal concepts would increase with age, a test for verbal concept formation was developed and administered to 668 children between the ages of 4 and 9. By varying sentences that describe nonsense figures, 4 variables were systematically explored. (MS)

This paper deals with three areas concerning early vocal development: (1) review and critique of existing experimental evidence suggesting that early vocal behavior has the properties of an operant response, (2) speculations concerning the role of non-verbal vocal behavior in early psychological development, and (3) suggestions for future…

This document reports on three years of clinical research involving the development of effective clinical intervention procedures for children with slow language development. The assessment and treatment approaches discussed in the report are based upon the developmental model of grammar described in Developmental Sentence Analysis (DSA), a…

A theoretical distinction is made between the growth of word meaning and the development of word sense in Vygotsky's terms. A recall from semantic memory task and the semantic differential were used to operationalize these two conceptions of meaning in a study of 72 children aged 5 to 10 years. Results replicated typical findings for the growth of…

This research investigated the use of conditional language by students in fifth, sixth, and seventh grades on four types of tasks, and compared this usage with scores on the Cornell Conditional Reasoning Test (CCRT) and with the ability to recall information. One hundred thirty-two subjects were randomly selected from school populations, and…
