Children's serial motor skill acquisition was studied within a neo-Piagetian framework. High and low M-processors (a designation of a child's ability to produce problem solutions) performed on a curvilinear repositioning task. A primacy-recency effect was evidenced for both groups on the age-related task, while a recency effect occurred for only…

This paper reports a study which examined the relationships of various facets of sensorimotor performance to abilities measured by a developmental examination of a sample of full-term and pre-term infants nine months after expected term date. This study addressed three questions: (1) Are there differences in the sensorimotor development of term…

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 purpose of this study was to determine the effects of three treatments of knowledge of results on the acquisition of an open complex motor skill requiring speed and accuracy (coincidence-anticipation). The 75 volunteer male subjects were randomly assigned to one of three treatment groups. One group was given informative knowledge of results;…

This report describes the movement characteristics of a three year old boy and girl as they performed a one-handed striking task over a one year period. Observations were made at 4 month intervals as part of a filmed, longitudinal study on the development of motor patterns. The one-handed striking pattern was elicited by asking the children to hit…

The contributions of specific motor-coordination disabilities and general slowness of motor function to the choice reaction times (RTs) of 22 mildly retarded adults were examined in two experiments. (Author)

A visually directed sensory motor training program with a 30-day duration did not enhance the depth perception of five-year-old children. (MM)

Mini-volleyball, lead-up games, and tournaments are described. (PS)

The motor proficiency of 55 learning disabled and 55 nondisabled students (mean age 9 years) was compared on a comprehensive battery of motor-skills tests. (Author/CL)

This article reviews research regarding the effect of heredity on athletic performance. Research on twins indicates that genetic makeup may have a strong role in aerobic capacity, adaptability to training, composition of muscle tissue, and personality traits relating to competitiveness and leadership.

A sample of 250 children from grades K through four were given a confidence scale, a motor competence assessment, and a questionnaire regarding sport participation in order to examine the interrelationships among perceived physical competence, motor competence, and participation in organized sport in young children. Results are discussed.…

An introduction to terms and concepts associated with resistance training is given. Sports associated with this training, such as power lifting and body building, are described. The merits of free weights versus resistance machines are discussed. The article recommends a training program for beginners. (Author/JL)

This study evaluated the influence of biological and environmental variables on the differences between the throwing performance of 100 five-year-old girls and boys. Results are analyzed and discussed. (Author/MT)
