Sammendrag
This study examines the role of a dynamic model in the acquisition of a slalom ski-type skill. It addresses the question whether the dynam ic model provider of information, of the geometrical or topological k ind, or acts as a distractor taking the observer's attention away fro m the performance i.e. acting as a secondary task, forcing the learne r into an intrinsic learning mode. A four condition design was used, with N=10 female students per condition. In Condition 1. a dynamic (v ideo) model of an expert performer was available to the learner provi ding both geometrical and topological information. Condition 2 emplo yed the same (video) model as in Condition 1, the body of the model b eing occluded so that only the movement of the platform of the appara tus was visible i.e., only geometrical information available. Cond ition 3 required observation of an irrelevant cartoon. The control group (4) were left entirely to discovery learning. The dependent v ariables were the amplitude and frequency of the movement of the ski- apparatus platform on which the subjects were required to stand, and the phase lag between the position of the platform vis-à-vis the cent re of the apparatus at the
