Background: The purpose of this study was to examine the effect of the follow-through on thrown ball velocity, potentially justifying inclusion of the follow-through in Roberton's five critical components. Method: Seventy-eight University students participated in the overarm, dominant hand, throwing task, which involved throwing a standard tennis…

Background: Cycling has gained more attention as an important lifelong physical activity. Learning to cycle independently without assistance is a milestone for most children that requires time and practice to master. Cycling was recently added to the motor development model and so a valid and reliable measure of cycling ability is required to…

Our identity develops with age, and many impacting factors will determine whether it is healthy or unhealthy. A particularly fragile phase of identity development occurs during adolescence when level of motor competence may be influential, yet is rarely considered. Purpose: The purpose of this study was to examine male and female adolescent's…

A critical aspect of perception-action coupling is the ability to modify ongoing actions in accordance with variations in the environment. Infants' ability to modify their gait patterns to walk down shallow and steep slopes was examined at three nested time scales. Across sessions, a microgenetic training design showed rapid improvements after the…

Three experiments investigated 5- through 8-month-olds' ability to encode self-propelled and caused motion and examined whether processing of motion onset changes when crawling begins. Infants were habituated (Experiments 1 and 2) or familiarized (Experiment 3) with simple causal and noncausal launching events. They then viewed the caused-to-move…

This study investigated how infants gather information about their environment through looking and how that changes with increases in motor skills. In Experiment 1, 9.5- and 14-month-olds participated in a 10-min free play session with both a stranger and ambiguous toys present. There was a significant developmental progression from passive to…

Four principles are drawn from approximately 100 years of research in the area of motor development. The principles are (1) children are not miniature adults, (2) boys and girls (children) are more alike than different, (3) good things are earned, and (4) no body (nobody) is perfect. Five sections of this article introduce some of the major…
