This study compared 36 learning disabled school-grade children with 17 controls matched for mental age on the ability to inhibit hand movement. Using a "Move A Ball Slowly" game-like apparatus, responses suggested older rather than younger disabled children had more difficulty. (Author)

Reviews literature on human fetal behavior. Includes descriptions of coupling of body movements and fetal heart rate and behavior maturation from conception to term. Discusses use of stimulus-induced behavior to examine sensory and cognitive development, and spontaneous and stimulus-induced behavior to assess fetal well-being. Notes research focus…

Evaluated role of visual input during reaching and grasping. Found that both infants and adults completed a reach and grasp to a darkened object but used vision when object remained visible. Infants contacted the object more often when it remained visible, although with longer durations and more movement units. Adults reached faster and more…

Over the past decade, cognitive approaches with children with developmental coordination disorder (DCD) have been investigated. Although studies have focused on intervention outcomes, few have documented the components of the approach that support the enhancement of children's performance. This study used systematic observation of videotaped…

This study was undertaken to determine the progressive development in movement and movement patterns (coordinated movements of body parts used involuntarily to achieve an objective) of children 2- to 6-years-old, to identify general characteristics which may be studied for appraisal of growth and development, and to study variations in movement…

This study was designed to provide observations of the vocalizations and language of infants and young children and of changes in the subjects' pattern of play with toys, as well as their locomotor activity in a playroom. One hundred infants and children ranging from 10 months to five years of age were observed for two 15-minute periods, one with…

These data appear to support the conception that the speech motor system can act as a mediator of other motor systems when speech'' is experimentally manipulated. (Author)

The underlying structure of the motor abilities represented by the "Short Form of the Bruininks-Oseretsky Test of Motor Proficiency," along with the consistency of the emerging factors by sex and two chronological age (CA) levels, were studied with 765 nondisabled children 4.6 to 14.6 years old.

Children from three to six years of age were tested to determine the relationship of age and sex to motor performance. Tests involved balancing, scrambling, catching, speed running, long jumping, and ball throwing. Although significant age and sex differences were found, it appeared that age generally was more closely related to performance than…

Two experiments examined developmental changes in accuracy of judgments about physical abilities in primary school children and college students. Subjects were asked to complete four physical tasks with and without benefit of practice. Found that children overestimated their physical abilities, individual differences in overestimation related to…

Three experiments examined vision's role in infants' grasping of horizontally and vertically oriented rods. Found that infants differentially oriented their hand regardless of lighting and similar to control conditions where they could see rod and hand throughout reach. Findings suggest that infants may use current sight of object's orientation or…

Movement responses to a stimulus could be either quantitative or qualitative, or could also be the answer to a pre-established problem. This process activates both divergent thinking and critical thinking. Divergent movement ability generates both quantitative and qualitative movement responses to a stimulus. The aim of this study was to examine…

The primary purpose of this study was to demonstrate whether children ages 5 through 8 could learn keyboarding skills. A secondary purpose was to examine the relationship between typing skill development and motor proficiency. A sample of 24 children was randomly selected from a group attending a summer school enrichment program. The…

A review of research on the effects of aging on motor performance provided evidence that age-induced changes within the central nervous system, particularly in the functioning of the non-dominant cortical hemisphere, result in diminished fluid abilities. The loss was most clearly manifested behaviorally as a decreased capacity to perform…
