Recent research has shown that 2-year-olds fail at a task that ostensibly only requires the ability to understand that solid objects cannot pass through other solid objects. Two experiments were conducted in which 2- and 3-year-olds judged the stopping point of an object as it moved at varying speeds along a path and behind an occluder, stopping…

This study used a set of Piagetian tasks to examine the sensorimotor skills of 40 profoundly retarded institutionalized children ranging in age from 8 to 14 years. (JMB)

Superimposes findings of research in learning disabilities on Piagetian stages of cognitive development. Results suggest that during sensorimotor stage, diagnosis of learning disabilities is difficult. Findings suggest delay exists in cognitive development of learning-disabled children during elementary school years, which corresponds to…

A cross-sectional study of language comprehension in relation to cognitive functioning in 48 10-to 21-month-old children, four at each month of age, revealed significant correlations between comprehension and five sensorimotor subscales. (Author/PHR)

The relationship between sensorimotor performance and communicative ability in 18 autistic children (40 to 108 months old) was studied. The children were administered the Means-End and Operational Causality scales from the Ordinal Scales of Psychological Development. In addition, the Ss were assessed on four measures of verbal and nonverbal…

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.

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…

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.…

The study compared play among five groups of children (ages 3-7 years): normal children (N=41); those diagnosed with language delays (N=241), those with autism but normal intelligence (N=71), those with autism and mental retardation (N=97), and those with nonautistic mental deficiency (N=86). Each child was evaluated using a 25 minute structured…

Findings from relevant research applying Piaget's theory to mental retardation, psychosis, and autism are reviewed. Many autistic individuals show an arrest in operative functions at the sensorimotor functions. The early arrest interferes with subsequent development of higher-level conceptual, symbolic, and social skills. (Author)

Learning, beginning in infancy, depends chiefly upon the nature and quality of movement experiences. Since 50 percent of a child's potential for learning is developed by age five, it is essential that movement programs be devised for children of preschool age. Movement programs must be geared to the individual child's developmental level. (JN)

Compared coupling characteristics of clapping simultaneous with walking or galloping, consistency across trials, and phasing variability among 4-, 6-, 8-, and 10-year-olds. Found that for walk/clap tasks, children adopted adult-like coupling patterns by age 8 and with the same consistency by age 10. Across age, children became less variable in…

Jean Piaget's theories about children's cognitive development are applied to the evaluation of childhood psychosis. Problems with the testing of such children are described, and results of a research project that used the Piaget-inspired Uzgiris and Hunt Ordinal Scales of Psychological Development to assess autistic children's cognitive processes…

Research on the cognitive development of play skills in young handicapped children is reviewed, focusing on two Piagetian styles of play--sensorimotor (exploratory) and symbolic (pretend and dramatic). The review emphasizes developmental patterns, areas of deficit, and implications for intervention in various handicapped groups. (Author/JDD)
