title: The Effect of Observational Practice by a Point-Light Model on Learning a Novel Motor Skill.
abstract: OBJECTIVE
  The purpose of this study was to investigate the effect of observing point-light and video models and physical practice on learning a crouch start.
  
  
  METHODS
  Thirty-two female students were randomly assigned into point-light, video, physical practice, and control groups. They performed 10 trials in pretest, 160 trials in acquisition phase, and 10 trials in 24-hour retention test. Kinematic features and reaction time were measured as dependent variables.
  
  
  RESULTS
  Results showed that physical practice group performed better than other groups in reaction time and range of motion of trunk and observational groups performed better than control groups in reaction time and range of motion of knee.
  
  
  CONCLUSIONS
  The results confirm the positive effects of observational practice on motor learning.
