Inexperienced sport climbers might perceive and utilize new opportunities for action by merely observing a model.

The purpose of this study was to evaluate whether observing an expert climber would enable inexperienced climbers to perceive and accomplish new possibilities for action and whether this would facilitate their climbing performance. The focus was on what information is obtained during observation of a motor action. Three groups of inexperienced male participants (N = 24) observed either a video model of an expert method of climbing, a video model of a novice method of climbing, or the climbing wall on video without a model. Participants subsequently climbed the wall. This procedure of observation followed by climbing was repeated five times. Analysis showed participants perceived and subsequently utilized information from the videotapes and that this resulted in faster and more fluent climbing (as assessed by the geometric entropy of the body center of gravity). The results are discussed in terms of perceiving and accomplishing opportunities for action or affordances.
