Learning a Motor Skill from Video and Static Pictures in Physical Education Students-Effects on Technical Performances, Motivation and Cognitive Load.

The purpose of the current study was to compare the effectiveness of a video and three different formats of static pictures (simultaneous-permanent pictures, sequential-transient pictures and sequential-permanent pictures) on the acquisition and retention of a complex judo skill in novice young adults. One hundred and thirty-three first-year students in the certificate in Physical Education (PE) were randomly assigned to either: a static-simultaneous-permanent pictures condition ( = 30), a static-sequential-transient pictures condition ( = 29), a static-sequential permanent pictures condition ( = 36) or a video condition ( = 38). They were instructed to observe and reproduce a complex judo technique () immediately after the learning phase (including a sequence of three trials-the acquisition phase) and after one week without observation (the retention phase).
