Age-related changes in self-definition were examined in 120 students from age 6 to 16 years. It is suggested that with increasing age there is greater self-extension and a reconceptualization of self and not-self relations. (GO)

This paper describes an attempt to incorporate the social psychological phenomenon of trait inference into existing developmental theory - principally the developmental system of Piaget. This goal is accomplished by examining the trait of inferences of children developmentally to establish the structural requirements of the process in terms of…

It was specifically concerned with cognitive tempo--the individual's tendency to be either slow and accurate (reflective) or fast and inaccurate (impulsive). A…

A study involving 31 adults with Down syndrome investigated their ability to reason. Results found they did not differ from typically developing children, matched on expressive and verbal ability, in transitivity and non-verbal analogical thinking; however, they did differ in categorical reasoning, classical verbal analogies, and short-term…

A study examined whether exemplar-specific or prototype representations were primarily used by 28 children (ages 10-12) with mild mental retardation in a categorization task consisting of two groups of make-believe animals whose features were ill-defined.

Many scientists are currently studying the manner in which individuals process social information. The reconstruction of attitudinal and subsequent behavioral information was studied to determine whether information about a person's schema can influence the interpretation of that person's subsequent behavior or whether the behavior itself is more…

This project had as its specific objective the development and field testing of a procedure for identifying the structure of technical concepts possessed by a group of selected quality control specialists. The associative theory of verbal behavior served as the rationale by which conceptual structures depicted by graphical maps of technical…
