Types of private speech produced by hyperactive and nonhyperactive boys.

ABSTRACT

Types and amount of private speech (audible talking that is not addressed to another person) were assessed during the free play of 16 hyperactive and 16 nonhyperactive boys. Verbalizations were coded into nine categories that denoted the boys' level of use of verbal control of their own behavior (Luria, 1961; Kohlberg, Yeager, & Hjertholm; 1968). Differences in amount and type of private speech between hyperactive and nonhyperactive boys were found to indicate that hyperactive boys may be presenting a specific or general cognitive lag in development. Treatment ramifications are discussed.
