There is a great need for theoretical frameworks to generate research that could help to guide the development of teacher education programs. Studies of successful adult functioning in complex careers support the construct validity of developmental stage as predictor. (JN)

A general theory of how children learn conservation concepts is presented. The acquisition process is described at an abstract level in terms of a rule-sampling system, implying a three-state Markov model with identifiable parameters. Three experiments testing the model's quantitative predictions about conservation learning experiments are…

The Matrices and Order of Appearance subtests of a Piagetian test battery were administered to a sample of second-grade children on two occasions under two test conditions: standardized testing and a dialogue between child and examiner. Differences for test condition and time of testing were found. (JKS)

This review presents a developmental analysis of children's capacity for self-evaluation via interpersonal comparisons. It is suggested that only at age eight or nine, when several cognitive concepts are understood, do children realize that similar others provide the most useful comparison feedback. Educational implications are drawn. (Author/SJL)

Discusses the relationship between language impairments and memory. A discovery process that can be used to determine the degree to which children's long-term memories vary across recall content and contexts, and a method for determining which memory facilitation strategies are the most effective are discussed.

Investigates the case of a 7-year-old boy with severe word-finding difficulties. The study used a series of theoretically motivated questions as a framework for psycholinguistic investigation to determine the cause of his difficulties. Findings indicated pervasive deficits in phonological processing, deficits interpreted as a developmental…

The "Ages and Stages Questionnaires," a parent-completed developmental monitoring system, is described, and various strategies for using the system to identify young children with developmental delays are compared. Strategies include mail-out, home visit, on-site (completed by either parent with assistance from service provider),…

Evaluates competing proposals for the underspecification of phonological representations against the facts of phonemic acquisition. Results indicate that context-sensitive radical underspecification provides a plausible account of each developmental stage and the transition between stages with minimal grammar change.

Evaluates the principle of laryngeal-supralaryngeal cyclicity by manipulating the domain cycle and phase relationship of the cycle as independent variables and by monitoring longitudinally the order of emergent phonemic distinctions in the sound systems of seven children with phonological delays as the dependent variable. Findings are discussed.…

Presents data from 4 Inuit children ages 2;0 to 3;6 that shows relatively early acquisition of both simple and complex forms of the passive. Within this age range, children are productively producing truncated, full, action, and experiential passive. Reasons for this precociousness, including adult input and language structure, are explored. (56…

Examines the timing of partners' talk in mother-infant engagements over infant age to determine whether variations occur in the incidence of the alternating mode. Findings reflect the facilitative effects of covocalization in preverbal infants and the need for the alternating mode with older infants. (31 references) (Author/CK)

Offers practical information in chart and list format for presenting literature to infants and toddlers in group settings. Highlights include developmental characteristics; sample book titles to match to age characteristics; strategies for planning and presenting storytimes; related resources; and a bibliography. (Author/LRW)

Structural models were used to examine developmental stages of antisocial behavior and their relation to during-treatment performance of 245 probationers in an inpatient substance abuse treatment program. Separate childhood and adulthood antisocial functioning components predicted psychological functioning and program perceptions during treatment.…

Focal theory is a framework for looking at psychosocial and leisure transitions in middle and later adolescence. Using cross-sectional survey data, found few gender differences in age-related relational transitions, but gender differences were apparent in shifting focuses of leisure involvement with age. Findings suggest a linkage between…

The first of two articles on play reviews the development of play in typically developing infants, toddlers, and young children, including Piaget's observations on the development of play; developmental play research following Piaget (research by Lunzer, Sinclair, Lezine, Lowe, Rosenblatt, Uzgiris and Hunt, Fenson and others, Watson and Fischer,…
