This study investigated young children's ability to solve probability problems and studied the cognitive processes proposed by Piaget and Inhelder as necessary to solve probability problems. The effects of tutorial and self-discovery training were measured and discussed. Results from 168 first-graders in five training conditions indicated that:…

This research deals with the development and relative importance of both the conceptual-cognitive and the aesthetic-affective aspect of the perceptual process at various age levels of children. Three tasks were chosen: (1) sorting drawings of human figures--a task that represents a more conceptual function; (2) expressing preferences for those…

Research is described concerning a factor analytic view of adolescent thought in Piagetian context. Included are a description of Piagetian tasks used for determining stage of mental development, studies concerning Piagetian task factor analysis, and the current factorial structure of adolescent thought.

This paper offers reflections on problematic aspects of the relationship between adolescent mothers and their toddlers. Similarities in the stages of development and the characteristics of both the toddler and the adolescent mother are identified. Both mother and child are seen to be at very vulnerable ages. The adolescent mother's developmental…

The objectives of this research pilot project were (1) to train 3- and 4-year-olds in cognitive and tactile discovery tasks; (2) to provide guidance for parents, enabling them to reinforce and review the concepts taught; and (3) to establish training and employment, as tutors, for central city high school and junior college students. A "discovery…

In a summer program, 351 Head Start children were assessed. Goals of the program were (1) to assess the educability of these children as a group, (2) to identify to public schools the children in need of early special help, and (3) to obtain information germane for future Head Start programs. Children were screened with reference to probable…

A group of 105 lower-lower middle class kindergarten children were tested on a set of single variable classification tasks and related-component tasks dealing with color and number. Children who failed to reach criterion on the classification test were randomly assigned to one of five experimental groups, stratified on the basis of performance on…

Two experiments which investigated the young child's ability to deal with multiplicative classes and relations (considered behavioral indices of concrete operations thought) in double series and cross class matrices are described and discussed. In the initial study, 160 children from preschool through grade 2 received six matrix subtasks…

Analysis of 65 children over a 4-year period on tests of operational and causal thinking offers support for Piaget's notion of stage progression. In kindergarten and grade one, the majority of children in this longitudinal study were between preoperational and the achievement stage of operational thought. By grade two, the majority had attained…

Based largely on research in adult development and aging, these readings and discussion questions pertain to such aspects of development and adjustment in middle life as the following: individual differences in aging; biological changes through the adult years; changes in the physical senses (vision, hearing, taste, smell, touch, and pain)…

The human life course is examined so as to clarify the nature and meaning of age to members of different social classes at different periods of their lives. The author utilizes a developmental framework: life is made up of interlinked role sequences involving cumulative learning. Each stage builds on the previous one. Within this framework, the…

Two experiments investigated developmental aspects of the two components of scientific reasoning: induction and deduction. In the first experiment, 98 subjects, ages 5 through 11, inductively identified four silhouetted pictures by removing, one at a time and in any sequence, as few covering pieces as possible. Results indicated that: (a) the…

Intended for individuals working with the handicapped, the guide provides information about physical fitness tests, perceptual-motor scales, and developmental profiles. Covered in an introductory section are the rationale and relevance of testing, basic concepts about tests, interpretation of test results, adapted physical education programs, and…

Challenges adult educators to provide the educational experiences and resources necessary for adults to handle life tasks. Introduces the "teachable moment", as part of a lifelong curriculum, which relates the tasks associated with each developmental life stage to appropriate adult education program responses and possible outcomes. (TP)

Reviews the history of human development, and of family development and its interdisciplinary nature. Explores variations as well as the universality of the family life cycle and developmental tasks. Presents examples of the applications of family developmental concepts by a variety of practitioners in the family field, offering ideas on research…
