This article describes tests which examined at what ages children could correctly identify right and left sides of pictures of themselves, another person, or an object. (CD)

Pascual-Leone's neo-Piagetian theory of development is used to predict the pre- and postinstruction distributions of scores on a subject-controlled digit placement task as a function of three parameters dealing with mental strategy and capacity. (Author/ED)

The paper describes "Partners in Child Develoment--A Creative Approach to Parenting," a developmental profile of 160 competencies of children (birth to 5 years) which is designed to be used by parents to chart their child's unique developmental pattern. It is explained that each competency is described, with suggestions for new…

Tested the hypothesis that understanding of the pretend-real distinction develops earlier than understanding of the theoretically related apparent-real distinction. Found 3-year-old children consistently performed better on pretend-real tasks than on apparent-real tasks, even when the tasks were identical except for the distinction tested. (SKC)

The authors report on a study designed to identify developmental tasks experienced by Mexican-American females from 18 to 34 years of age. They state that (1) a stable relationship, (2) education, (3) independence, (4) children, (5) friendships, and (6) community were consistently important. (CH)

Surveyed 485 undergraduate students to determine on which developmental tasks they believed they were currently working. Results indicated students were simultaneously engaged in developmental tasks associated with middle childhood, adolescence, and early adulthood, although they identified themselves as being in early adulthood. Results supported…

Three-, four-, and five-year-olds were given problems to test their ability to recognize absolute number and relative order. Results suggest that children understand number as an absolute amount before they understand it as part of a progressive sequence in contradiction to the "ordinal theory of number." (Author/DST)

The author critically reviews the literature on the developmental approach to mental retardation by examining such aspects as motivation, interrupted tasks, probability learning, institutional effect, statistical problems, and Piagetian tasks; and questions whether there is a substantial body of valid evidence supporting claims of…

Investigated the development of informal addition in Dioula (A Moslem ethnic group from West Africa) from childhood to adulthood and the effect of schooling on mental arithmetic. Compares these data with results from a study of children from the United States. (MK)

Adjustment problems of disabled adolescents and appropriate rehabilitation programs are examined. Specific problems of the disabled are explained for each of the following normal developmental issues: separation, body image, achieving independence, sexual identity, aggression, depression, and problems of educational and vocational development. (DB)

Data evolving from processes which are developmental or hierarchical in nature are often analyzed by using latent class or latent structure models. A procedure for estimating such models when the model is not "identifiable" is presented. (JKS)

Discusses various aspects of adolescents' needs and feelings in relation to their efforts to become competent human beings. (SS)

Suggests some difficulties and challenges in understanding and teaching Piaget's new theory. Outlines some differences between Piaget's new and standard theories, such as the diminished status of the emergent skills that mark the onset of concrete operational thinking and the perception of achievements in concrete operations as empirical…

Four- to 11-year-olds made duration, distance, and speed judgments on Piagetian tasks where cars ran on parallel tracks. Among younger children, duration and distance judgments had approximately the same difficulty. Among older children, distance judgments were easier than duration judgments, and symmetry of effects of temporal and spatial…

As an outgrowth of the theory of flow, looks at some fine distinctions regarding the adolescent's optimal conditions for growth. Points to the importance of the adolescent's ability to reinterpret conflicts which crop up in raw experience, to overcome psychic entropy with long-term challenges or "life themes," and to find new meaning and…
