Theorists and researchers have developed abstract divisions in the life span to mark significant stages. To explore the conceptual labels individuals use to make divisions in their life spans, 92 adults, aged 20 to 55 years, marked significant milestones on a lifeline. Participants also completed a demographic questionnaire. Data on the labels…

Family theorists have considered the idea of boundary in terms of the concepts of disengagement and enmeshment. Disengaged families are those having rigid, well-delineated boundaries that are often impermeable. Alternately, enmeshed families have diffuse ego boundaries, acting as if all are part of each other, and are likely to produce an…

Measures designed to test two components of attention (decison making and maintaining attention over time) were studied in 36 educably mentally retarded (EMR) boys at three age levels (10, 13, and 14 years). Multivariate analyses, followed by univariate and paired comparison tests, indicated that both EMR and normal Ss increased in attentional…

The importance of play and its contributions to the intellectual, social, psychomotor, and emotional growth of the child is just now being recognized and day care teachers are regularly required to justify the inclusion of play and games in programs for young children. Two types of justification are commonly heard: the nondescriptive and the…

A discussion of models of intellectual development and their application to education identifies the two major groups of such models and examines recent attempts to combine them. The two types of theories are described as the psychometric models, which see intellectual growth as the incremental amassing and associating of discrete ideas, and the…

Relating disorders to Piaget's and Freud's developmental stages, it is proposed that, in the somatopsychic group, resomatization is associated with primitive modes of thinking and feeling; while in the psychosomatic group, resomatization is connected with an operational type of cognition and emotion. A case history is used as illustration.…

Emphasizes the rich potential of stimulating the growth and development of young children through playing group games. Developmental guidelines for choosing appropriate games are based on Piagetian theory. (CM)

This study attempted to clarify the developmental progression in the understanding of conditional sentences by evaluating the capacity of 71 third, 70 sixth, and 64 ninth graders to learn three interpretations of abstract conditional sentences. (JMB)

Thirty-seven middle-class white children, ages 5-8, were tested on eight Piagetian tasks and the Rorschach test, and divided into preoperational, transitional, and concrete operational groups. Measures of primary process vs. secondary process thinking were found to be related to the Piagetian stages of development. (GDC)

Theoretical concepts from multivariate developmental psychology and systems theory are used to describe qualitative and quantitative change in three cognitive subsystems: perceiving, conceptualizing, and symbolizing.

Two models of intertask relations, Wohlwill's divergent-decalage and reciprocal-interaction patterns, were evaluated for their fit to cross-classification tables which showed the joint classification of 101 children's performance on all possible pairs of eight concrete operational tasks. (SB)

A test of motor stage theory was conducted to screen cross-sectionally for the existence of "horizontal structure" among motor sequences within four movement components of overarm throwing and overarm striking for force. Subjects were 58 preschool and elementary school boys. Findings are discussed. (Author/MT)

Used an event-sampling procedure to determine developmental patterns of sex differences in verbal aggression of 32 nursery school children. Verbal aggression was more common than physical aggression for both sexes. Another study that sampled free speech of first, third, and fifth grade children found only fifth grade boys significantly more…

Five studies investigated children's perception of scale and contour in melodies. It was found that young children can detect key transposition changes in familiar and unfamiliar melodies and are sensitive to melodic contour over transformations that preserve it, yet distinguish spontaneously between melodies with the same contour and different…
