Forty-four 7- and 8-year-old boys were classified as having high or low concrete reasoning ability or as being in a transitional state. Findings indicated that frustrated boys exhibit regression more than nonfrustrated boys and that the extent to which they regress is dependent upon cognitive level. (GO)

Evaluates the effects of an intensive period of dramatic play upon the cognitive structures of 12 three- to five-year-old children. (CM)

A Piagetian task of spatial functioning and a modified classification problem (simple intersection) were administered to children to test the degree of relationship between logical and sublogical operations by defining their common cognitive components. (Author/DB)

In order to determine if there are developmental effects on information integration and dispositional attributions, 145 adolescents at two ages (13 and 18) were presented with information about hypothetical peers. (Author/MP)

It was hypothesized that Piaget's argument on behalf of the reorganization of cognitive processes would gain empirical support from a color/form, matching similar objects problem for 52 6-year-olds from a variety of socioeconomic backgrounds. (Author/MS)

This study tested the hypothesis that objective and subjective responsibility responses in moral judgment may be formally equal forms of cognitive organization. Results showed that subjects acting as offenders gave subjective responsibility responses; the same subjects acting as offended gave objective responsibility responses. Thus, subjects'…

Results indicated that progress through adolescence leads to greater differentiation, abstraction, and integration. The emergence of the ability to abstract was considered the most important cognitive development in the adolescent's self-system. Major transformations appeared after age 15. (Author/DB)

A total of 219 male and female college students returned questionnaire measures relating to cognitive complexity, dogmatism, and repression-sensitization. Analyses revealed very complex interactions among the variables. (Author/SB)

The association of locus of cerebral hemispheric specialization of spatial function with identity and equivalence conservation judgments was tested in a group of four- to six-year-old right-handed children (N=31). (Author/MP)

This study attempted to identify the factors of intelligence associated with the solution of a Piagetian task. Liquid conservation and 18 psychometric tests which included subtests from the WISC, ITPA, Raven Matrices, Primary Mental Abilities, and others were administered to 133 first- and second-grade boys and girls. (MS)

Developmental changes in a variety of cognitive processes as a function of age and schooling were examined in 160 rural Guatemalan children aged 5, 7, 9 and 11 years. (BD)

This study examined the hypothesis that perceptual errors on a task requiring subjects to take different viewpoints could be explained in terms of response bias. Results were consistent with response bias hypothesis: making an egocentric error is different from behaving in an egocentric manner. (Author/SB)

An investigation was made of the structure of riddles, riddle content, and the function of riddling among children ages 5 to 14. Interaction data and 1195 items were taped and hand-recorded during riddle sessions with 101 children from kindergarten, second, fourth, fifth, seventh, and eighth grades. (MS)

Preschool children between 3 and 5 1/2 years of age participated in a learning task in which a conditional relational problem was presented in either a blocked or random series. Prior training on the components of the task was also varied. (BD)
