A total of 100 children from divorced and separated families were compared with 100 children from intact families in this investigation of ways in which children handle the concepts of family membership and relationships. Children were given two social and two physical tasks: a family identity task; Piaget's interview for determining the…

This study was designed to determine if: a) attentuation of irrelevant information on a selective attention task would result in increased selective attention, and b) a developmental increase in selective attention would be replicated with the use of a different procedure of data analysis than has been used previously.

Investigated the impact of developmental concerns on 140 college students' self-disclosure using an instrument based on Erikson's psychosocial theory of development. Results indicated two developmental issues were found to be significant predictors of willingness to disclose problems to fathers and to same- and opposite-sex friends. (Author/BL)

Examines the role of basic cognitive-processing efficiency as the source of developmental variance in cognitive performance. Two experimental tasks, memory and visual scanning, were used to investigate age effects on the search-processing parameter. Subjects were 9-, 11-, 13-, and 15-year-old children. (CM)

The use of rules on nonverbal balance scale problems was studied among 5- to 19-year-olds. Latent class analyses indicated that children used rules, that different rules were used by children of different ages, and that both consistent and inconsistent rule use occurred. A model for the development of reasoning about the balance scale task was…

Students (n=150) ages 11, 14, and 17 were asked to explain the meanings of 24 different idiomatic expressions. Performance on the task gradually improved as subject age increased. High-familiarity idioms were easier to explain than moderate-familiarity or low-familiarity expressions. Easier idioms tended to be more transparent. (Author/JDD)

The present study was conducted to examine the development of attentional and oculomotor control. More specifically, the authors were interested in the development of the ability to inhibit an incorrect but prepotent response to a salient distractor. Participants, who ranged in age from 8 to 25 years, performed 3 different eye movement tasks: a…

A proposed study of the differences in the way children perceive, approach, and behave in problem-solving situations is described. The behavioral measure to be used is "glancing," which has been related to outerdirectedness. Children will be given two sets of two puzzles to put together. On the basis of the number of glances and the situation in…

Considers adult educational needs according to the idea of developmental tasks along with changes in adult life cycles and calls for changes in adult education and legislation. (MF)

Perceptions of parents and their adolescent children about a number of developmental tasks were compared for 508 Dutch families. Parents consistently indicated later ages for the achievement of developmental tasks than did adolescents, but they had similar views of the sequence in which achievement of developmental tasks should occur. (SLD)

Investigates the development and production of spatial deictic terms ("this/that", "here/there", "my/your") in the context of a hide-and-seek game using preschool children and college age adults. (Author/ED)

Reports on three studies which investigated the development of the concept of horizontality in subjects from nursey school through college age. Normative data collected allowed for evaluation of Piaget's stages and for differences due to age, sex, and apparatus shape and orientation. (ED)

An investigation of Piaget's theory of object concept development through a series of six tasks administered in a combined longitudinal/cross-sectional design (which incorporated a number of methodological controls). Subjects were 36 infants who received the six tasks during each of three testing sessions over a 6-month period. (Author/ED)
