Investigated postural constraints on movement of 15 6-month-old infants. Results suggested that each of the developing capabilities of orienting, reaching, and kicking assumed a specific function for locomotion at the stage of crawling. (RJC)

Results of a study of 68 infants of 5-14 months revealed that partial optical flow is generally sufficient for inducing postural compensations, but the amplitude and consistency of the response depend on the location of the flow in the optic array. (RJC)

A variety of educational gymnastics, games, and sports tasks geared toward young children are described. They focus on jumping, taking weight on various body parts, large apparatus movement, ball skills, striking skills, throwing and catching skills, and travelling with a ball. Suggestions are also presented regarding the preschool handicapped…

Reviewed are the causes of oxygenation deprivation during the birth process, effects on the brain, clinical manifestations, developmental consequences in terms of cognitive and motor deficits, and implications for educators. (JDD)

Presents activities that physical educators can use to help young students who are still learning basic ball control skills. Students use a pinky ball (a small, low-bounce rubber ball) to stay on task while improving ball control skills. Games include seven-up, errors, box ball, and hit the coin. (SM)

This study of single-joint elbow flexion movements by 10 subjects with Down's syndrome (ages 14-19) and 6 control subjects concluded that there are no major qualitative deficits in the motor control mechanisms of individuals with Down's syndrome, but there might be problems with proper modulation of motor commands. (Author/JDD)

The activity level of 60 pairs of infant twins was measured for 2 days. Differences in activity level for monozygotic and dizygotic twins, as indicated by motion recorders and parent ratings, showed evidence of genetic influences. (BC)

Seven infants were tested between the ages of 6 and 25 weeks to see how they would grasp objects presented in full light and glowing or sounding objects presented in total darkness. In all three conditions, the infants first grasped the objects at nearly the same time, suggesting that internal stimuli, not visual guidance, directed their actions.…

A theory of infant skill acquisition was supported by observations, over a six-week period, of the bouncing activity of eight infants while they were supported in a harness assembly. Observed three stages of activity: an initial assembly stage, when movement was irregular and variable in period; a tuning phase of more periodic movement; a final…

Comparison of ages at which typically developing infants and infants with Down syndrome achieved vocal and motor milestones found that rhythmic behaviors (canonical babbling, hand-banging) were associated with each other and somewhat delayed in Down syndrome infants. Postural behaviors (stepping, standing, sitting, creeping) were also associated…

Presents a success-management model for motivated learning which provides physical education teachers a framework for enhancing students' desire to work hard and maximize skill learning. The model's three phases are: basic instruction to help students begin learning skills; change in the motivational climate from task to ego orientation, with…

This study compared hand preference and motor skills in 20 children with autism with 40 children either typically developing or with developmental delays. Results indicated that the lack of hand preference in children with autism was not a function of their cognitive delay or a lack of motor skills. Results supported the bilateral brain…

Through the study of motor development, the physically educated person will understand that individuals develop at their own rate and require both time and practice to acquire new motor skills. The physically educated person needs to know about motor development in order to monitor his or her own change and become an independent learner.…

Contrary to past thinking, at birth, infants are capable of exploring their environment and interacting with other humans. They become aware of and learn about their world by observing, exploring, playing, and interacting with their caregivers. Motor skills play a major role in this process, which is achieved by allowing infants to move around,…

The study follows up on the contention that self-controlled feedback schedules benefit learning, because they are more tailored to the performers' needs than externally controlled feedback schedules (Chiviacowsky & Wulf, 2002). Under this assumption, one would expect learning advantages for individuals who decide whether they want to receive…
