Examines the relations of levels of task engagement to investigation and visual attention in data from 30-month-old children. Finds significant correlations between task and other mastery behavior. Postulates task engagement as valid assessment of mastery behavior. Suggests the motivation for young children's play is acquisition and mastery of…

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 paper discusses problems with traditional definitions of dyslexia and reviews research that suggests a more comprehensive definition, viewing dyslexia as a developmental language disorder that involves a deficit in phonological processing. The disorder is seen as manifesting itself in various phonological difficulties as well as in a specific…

Adulthood for females is a complex maturational process, rooted in the mother-daughter relationship. To investigate the dynamics of the mother-daughter relationship and its influence on maturing, 20 women, ranging in age from 30 to 75, were interviewed for 6 to 8 hours over a 1-month period. The subjects were chosen for their self-reflective…

One of the major developmental tasks of adolescence is establishing a unified self-concept, or identity. Four identity statuses (conceptualized by J. E. Marcia as identity achievement, foreclosure, identity diffused and moratorium) are related to (1) the presence or absence of crisis, and (2) a resulting commitment to goals. To examine the…

Argues that Susan Sugarman's article in this issue contains some valid criticism of assumptions in developmental psychology, but that some of her conclusions regarding other assumptions need to be questioned. Suggests that many problems raised by Sugarman would disappear if developmental psychologists concentrated on children's early achievements…

Tests the claim to comprehensiveness of Bloom's taxonomy of educational objectives by analyzing educational objectives of some freshmen orientation programs and those connected with human developmental tasks. It is concluded that the taxonomy should be enlarged with a fourth domain: actual induction into tasks for which students are being…

Data on 52 individuals with and 62 individuals without autism were analyzed to assess developmental aspects of the DSM-III-R (Diagnostic and Statistical Manual III, Revised) diagnostic system. Findings indicate that DSM-III-R criteria are more developmentally oriented and more behaviorally specific than previous criteria, but the diagnostic…

Adult children who return home are responding to unemployment and financial need, but factors such as dependence, protection needs, and parental happiness appear to be involved in long-term stays. This paper combines survey data to identify factors for successful living arrangements, and areas of conflict and dissatisfaction. (Author/NRB)

The paper notes A. Hore and W. Tryon's support of the developmental position that persons with and without mental retardation of similar mental age show similar cognitive patterns, but suggests that mental age is psychometrically invalid and Piagetian tasks are inappropriate to evaluate this position. An information processing approach is…

Argues that there are significant ways in which neither Piaget nor his successors in developmental psychology have adequately described the child's mind and how it changes. Proposes alternative guidelines for research that aims more directly at identifying essential constituent features of the child's mental reality. (PCB)

The syntactic development of preschoolers (n=22) who later became disabled readers was compared to that of similar children who became normal readers. Expressive and receptive syntactic abilities were examined from age 30 to 60 months. The dyslexic group was poorer on all measures until age five, when both groups exhibited similar syntactic…

The purpose of this paper is to review and synthesize the literature on adult development and to suggest how this information can be applied to the practice of adult education. The first section discusses the nature of adult development, its definition, and key concepts. Sequential patterns of change in adulthood are examined in section 2,…

Reports on a study of young children's abilities to discriminate between two chords played as the accompaniment of a melody and played alone with no melody. Finds that age, type of stimulus, and the interaction of these two variables affected children's performance significantly. (CFR)

Previous research on intelligence and aging has relied on tests developed for younger adults, which often incorporate many factors that could impede optimal performance in elderly populations. To investigate short-term longitudinal changes in memory, intelligence, and perceived competence in everyday situations among older adults, 227 adults were…
