Research on object exploration by infants addresses milestones in the process by normally developing infants, including spontaneous manipulation strategies. Implications for developmentalists working with high-risk preterm infants are noted, including the need for direct assistance in manipulation and for selection of materials. (CL)

The conceptual categories that children have developed in their second year were studied in five experiments using object manipulation tasks. Subjects included 152 children from 18 to 31 months of age. These very young children had formed global conceptions of many domains of objects. (SLD)

Tested infants in their second year with a box task to determine whether they would show a hand preference in solutions involving complete differentiation of roles for the two hands. (HOD)

Studied the early development of exploratory behavior in 99 infants of 2-5 months. Results show that there are significant changes in spontaneous multimodal exploration of a novel object between 2 and 5 months. (RJC)

The development of object play was longitudinally examined in 40 children ages 11 to 27 months. The types of object play observed in nondisabled children were observed in children with disabilities at comparable developmental ages. Duration and frequency of active involvement with objects were greater for nondisabled children than for children…

Although a considerable amount is known about the development of object manipulation during the 1st year, less is known about how infants manually explore surfaces and relate objects to surfaces. To address these issues, 60 infants (20 each at 6, 8, and 10 months of age) were presented hard and soft objects on tabletop surfaces, which varied in…

An interview taped in 1978 with Constance Kamii, a child development researcher who studied Piagetian theory at the University of Geneva, is presented in this document. When asked what teachers of young children should keep in mind, Dr. Kamii talked about teaching to the child's level and cautioned against dealing with symbolic materials, advising…

A MAIN PROBLEM ARISING IN THE STUDY OF CATEGORIZING BEHAVIOR IN PRESCHOOL CHILDREN BY MEANS OF SORTING PROCEDURES WAS THAT PERFORMANCE APPEARED TO BE VERY MUCH A FUNCTION OF THE CHILD'S COMPREHENSION OF THE PARTICULAR VERBAL INSTRUCTIONS EMPLOYED BY THE EXPERIMENTER IN PRESENTING THE TASK. THE SPECIFIC AIMS OF THE FIRST STUDY WERE TO INVESTIGATE…

Examined in a longitudinal study of children were correspondences and correlations between early language development on the one hand, and the manipulation of objects and play development on the other. There were developmental correspondences between the onset of five language landmarks (the emergence of first word, referential word, demonstrative…

Various counting tasks were presented to 24 congenitally, totally blind children, aged 3-13, to determine the behaviors employed to ensure accurate counting. Three dimensions of tactile strategies were found, including "scanning,""organizing," and "partitioning." A developmental progression in the ontogenesis of each…

The purpose of this study was to investigate the effects of a creative movement program on gross motor skills of preschool children. Sixty children between the ages of 3 to 5 were drawn from the population of a preschool in Taichung, Taiwan. An experimental pretest-posttest control-group design was utilized. The children enrolled in the…

The manual development of 148 blind, visually impaired, and visually impaired multi-handicapped students, aged 3-19, was studied. Results indicated a significant relationship between object manipulation and speech, and an inverse relationship between object manipulation and stereotypic hand mannerisms. Optimal development of manual functions and…

An understanding of the stages involved in children's development of sensory motor integration would aid in the creation of instructional strategies in physical education. These strategies would optimize both the child's physical coordination and creative development by increasing the correlation between the demands of a learning environment and…

The purpose of the study was to determine whether particular aspects of movement control influenced the performance of 2-year-old children on a standard developmental test, and thus influenced assessments of intellectual progress based on that test. Six cerebral-palsied (CP) children were compared with six children not suffering motor system…

SUGGESTIONS ON MEETING NUTRITIONAL AND FEEDING SKILL NEEDS OF HANDICAPPED CHILDREN ARE PRESENTED FOR PARENTS. PRINCIPLES OF GROWTH AND DEVELOPMENT COMMON TO ALL CHILDREN AND THE EFFECT THIS DEVELOPMENT HAS ON FEEDING ARE DISCUSSED. INSTRUCTIONS ARE GIVEN FOR ENCOURAGING CONTROL OF SWALLOWING, SUCKING, TONGUE CONTROL, CHEWING, AND SELF-FEEDING.…
