The majority of 63 elderly women were able to pass tests in the conservation of mass (98 percent), volume (100 percent), and surface area (65 percent). These results conflict with previous research about Piagetian abilities of elderly people. (RL)

Three levels of mathematical concepts and three theoretically corresponding levels of cognitive development were posited. Children's test results were consistent with predictions for each age group, leading to the conclusion that, for concept attainment at each level, a minimum information-processing capacity is a necessary, but not sufficient,…

This investigation attempted to describe the developmental sequence of visual motor short term memory in mentally handicapped boys (mental ages 6, 9, and 12) during conditions of rest and interpolated activity, and to explore their use of spontaneous rehearsal strategies. Results are compared with those for normal boys. (Author/SJL)

Presents a framework and principles for counseling belligerent counselees, integrating moral reasoning and behavior contracting. Counselees move from the punishment stage to a trade-off and socially responsive stages through contracting aimed at improved behavior, recognizing that behavior causes consequences, inducing positive behavior through…

Provides data incongruent with Piaget's idea of a concrete operational stage. Shows no clear-cut termination of preconceptual thinking and no simultaneous conceptual development in the three content areas (number, space, and time). (Author/RL)

Assuming that subject responses rank order stimuli by preference, statistical methods are presented for testing the hypothesis that responses conform to a unidimensional, qualitative unfolding model and to an a priori stimulus ordering. The model is suitable for the analysis of structure in attitude responses, preference data, and developmental…

Investigation of the relationship between maternal employment and behaviors and attitudes of preadolescents and adolescents indicated significant differences only for preadolescents regarding sex role ideology. Results suggest full-time maternal employment has few effects on behaviors and attitudes of school-age children from intact families.…

Investigates causal dynamics underlying the negative relationship between wife's employment and family size. Results indicate that during early stages of marriage and family building the presence of young children consistently exerts a strong negative effect on wife's employment. The effects from wife's employment to her subsequent fertility are…

Within diverse sets of nonmarital relationships it is postulated that similar developmental stages emerge. Delineation of these stages provides a framework for understanding the many complexities of nonmarital interacting systems. Five hypothetical developmental stages are presented and applied to two types of nonmarital dyads. (Author)

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)

Outlines the stages of prosodic development that children follow from the beginning of word acquisition through the end of the second year of life. How these stages can be used to provide a model for treatment when working with children who display delayed phonological development is addressed. (Author/CR)

Age 3 follow-up data are presented for sample of 34 toddlers diagnosed between ages of 24 and 31 months with expressive specific language impairment. Late talkers made more rapid progress in lexical development and in descriptive, explanatory, and definitive use of language than in syntactic and morphological language. Toddlers who'd been more…

Describes the experiences of individuals with Usher Syndrome, discusses the lack of appropriate services and the failure of professionals to provide sufficient information on the condition, and stresses the importance of access to information and the acquisition of new skills before the visual impairment becomes severe. (Author/CR)

Outlines Piaget's late ideas on categories and morphisms and the impact of these ideas on the comprehension of the inclusion relationship and the solution of arithmetic problems. Reports a study in which fourth through sixth graders were given arithmetic problems involving two known quantities associated with changes rather than states. Identified…

This longitudinal study assessed the narrative language development of primary grade children with slow expressive language development (SELD) as toddlers who either had or had not moved into the normal range of expressive language by early school age. Deficits in narrative skills tended to disappear in children with a history of SELD, though…
