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)

In a task in which 4- and 7-year-old children were asked to select a photograph depicting the visual perspective of a puppet which was placed at various locations around a dollhouse, three types of errors were examined in relation to the shielded vs. nonshielded condition, age, and type of vantage point.

Twenty severely retarded adults performed on the pursuit rotor apparatus in a study of the relationship between intelligence and motor task complexity. (CL)

A developmental reversal in accuracy was obtained for third and sixth graders and adults who judged class membership of patterns presented in a same-different task. Reversal accuracy appeared to result from an increase with age in orientation-free judgments. This hypothesis was confirmed in the subsequent two experiments. (GO)

Investigated the development and fragmentation of categories over chronological and mental age without the requisite of free recall. Kindergarten, fourth grade, ninth grade and retarded students labeled and categorized chromatic slides of picturable objects. (GO)

Stories written by school-age children were examined for sex and age differences in the assignment of emotions and prosocial and aggressive behaviors to the story characters. (Author/ABB)

Concerns the development of children's understanding of representational change and its relation to other cognitive developments. Two experiments involve day care children, aged three, four, and five years. Results suggest that children begin to consider alternative representations of the same object at about age four.

Three groups of elementary school students, matched on reading ability and with similar cognitive profiles, were administered tasks assessing their inventory of reading skills. Results support a developmental lag model of reading problems of nondyslexic children. (Author/RWB)

Examines a general developmental hypothesis concerned with children's understanding of perceptual experience, memory, intentions, and emotions. It is hypothesized that young children view the mind as passive in relation to the external world and regard external events as determining subjective experience, whereas older children know many ways that…

Interpersonal problem-solving skills of 17 mildly retarded students and two groups of nonretarded subjects (Ns=30) matched on mental age (MA) and chronological age were assessed using hypothetical problem solving situations. Results indicated similarities between mentally retarded subjects and MA matched controls in types and number of strategies…

Tests two hypotheses concerning developmental change in the speed of cognitive processes: (1) age differences in processing time reflect changes that are specific to particular tasks, and (2) age differences in processing speed do not reflect task-specific change but are due instead to more general developmental change. (HOD)

This study tested 142 youth 12 through 16 years of age with a special percept-genetic creativity test, a creativity-fantasy scale, and a percept-genetic personality test. Creativity was defined as the inclination to transgress the confines of an established perceptual context. Results are discussed and the development of creativity from preschool…

Describes three themes that have informed research on cognitive development in sub-Sahara Africa over the past 10 years: (1) extending the range of generalizability of Western theories; (2) interpreting the uniqueness of the African situation; and (3) deriving implications for social policy. (Author/AS)

The Situation Scale for Adolescents, an extended version of the Imaginary Audience Scale, was administered to several hundred youngsters in the seventh, ninth, and twelfth grades. The scale, assessing self-consciousness in two types of social situations, proved to be reliable, but yielded confused results regarding age and sex differences.…
