This study investigated whether age, sex, speed, and practice affects the acquisition of coincidence-anticipation (C/A) performance accuracy of children ages seven to twelve. (C/A refers to the ability to make a motor response coincident with the arrival of an object at a designated point.) The subjects used in this study were 84 elementary…

The behaviors and interactions of preschool-aged siblings in object-oriented and body-oriented conditions were observed to discover if the child's siblings significantly influenced motor skill development. This study focused on categories of sibling behaviors and interactions. (Author/DF)

This interim report is part of a longitudinal study of developmental behavior designed to determine whether infants from culturally disadvantaged homes have different developmental patterns than infants from advantaged homes. Twenty six culturally disadvantaged infants were individually evaluated on the Bayley Scale of Infant Mental and Motor…

The running patterns of two-, four-, and six-year-old children were analyzed to determine how age and sex differences affected selected kinematic and kinetic variables. Differences tended to involve displacement, velocity, and magnitude of force measures. Sex differences concerning the leg swing were noted. (Author/PP)

The Developmental Indicators for the Assessment of Learning (DIAL) test was used to evaluate 610 children, aged 2-1/2 to 5-1/2. Performance varied by race, sex and age,leading to the conclusion that our understanding of basic characteristics of movement performance in preschool children is far from complete. (Author/MT)

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. (Author/SEW)

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…

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…

The purpose of this study was to determine differential relationships among teacher perceptions of student expression of effort, teacher expectation, grade, school, teacher, sex, and being handicapped/nonhandicapped on gross motor performance among handicapped and nonhandicapped children integrated together in physical education classes.…

To clarify patterns in the rate of motor development, children observed between kindergarten and second grade were refilmed, performing an overarm throw, when they became seventh-grade students. Results were compared with predictions made earlier. Differences in the skill levels of boys and girls and differences in their throwing experience are…

This study investigated whether a pattern for the development of motor ability could be discerned, using the same range of motor performance tests with boys and girls at 10 different age levels. Researchers did not find a pattern as clear as has emerged in personality and intelligence development. (PP)

The Motoric Music Skills Test was administered to 808 children, ages three to six, from seven Kansas communities. Analysis of descriptive and inferential data indicate that the measured skills increase with age and differ by sex. Race, community size, and previous musical instrument experience were not significantly related to test performance.…
