THE PURPOSE OF THIS STUDY WAS TO FIND OUT WHETHER SOCIAL CLASS DIFFERENCES IN INTELLECTUAL DEVELOPMENT ARE PRESENT IF (1) CHILDREN FROM SOCIALLY DISORGANIZED SLUM FAMILIES ARE COMPARED WITH CHILDREN FROM STABLE, LOW INCOME AND MIDDLE INCOME FAMILIES, (2) THE PIAGET OBJECT SCALE, A NEW MEASURE OF COGNITIVE DEVELOPMENT BASED ON PIAGET'S SENSORIMOTOR…

This discussion centers on language development in young children particularly as it relates to Piaget's work. The author believes guidelines are lacking for describing structurally the outcome of the language acquisition process at different stages and that there should be more collaboration between linguists and psychologists in this area.

The study reports the findings of a meta-analysis, the application of statistical methods of data synthesis from individual studies, reviewing 180 studies assessing the efficacy of perceptual motor training. Perceptual motor training was not found to be an effective intervention technique for improving academic, cognitive, or perceptual motor…

Sports-related tool use abilities in children were investigated within a neo-Piagetian framework of development. The object was to establish whether development in the motor domain proceeds in a "stage-like" fashion. A model was developed which suggested how general and precise structural changes might manifest themselves in the sub-domain of tool…

Results confirmed that children differentially use knowledge of results and suggested that any description of motor skill acquisition must account for the complex interaction between developmental level and the difficulty of the task at hand. (Author/DB)

Observed 12-month olds, with their mothers and independently, acting on objects from home and objects brought by the experimenter as new exemplars of previous toys. Found that conventional actions were more frequent in joint than in independent activity. In independent activity, conventional actions were more frequent with customary than with…

The volume addresses itself to two basic competencies needed by teachers of the slow learning child: a rationale permitting consistent interpretation of the child's learning behavior and a repertory of techniques for presenting information in a myraid of ways, from which the teacher can select classroom presentation methods most appropriate for…

An analysis is made of the reciprocal relationship between play and three areas of interaction between the brain and human development: (1) the affective characteristics of play and the brain; (2) developmental theories of cognition and play; and (3) creativity as a continuation of the brain's need for play.

The article describes the program used in the Belmont (Massachusetts) public elementary schools involving the Dalcroze Eurhythmics approach to music and movement with special needs children. (SB)

Recent findings related to neurological research include: (1) the Proster Theory implies that the brain works by sets of programs or prosters; (2) the Brain Growth Spurts theory defines the growth of the brain in spurts with cycles of rest; and (3) in the Hemispheric Specialization Theory, the left and right hemispheres of the brain have specific…

This book presents a comprehensive and detailed theory of early human development based on the principles of dynamic systems theory. It raises fundamental questions about prevailing assumptions in the field and proposes a new theory of the development of cognition and action, unifying recent advances in dynamic systems theory with current research…

Development of object permanence skills was examined longitudinally in 20 visually impaired infants (ages 4-25 months). Order of skill acquisition and span of time required to master skills paralleled that of sighted infants, but the visually impaired subjects were 8-12 months older than sighted counterparts when similar skills were acquired.…
