Three experiments examined the relative efficacy of different imagery perspectives on the performance of tasks in which form was important. In Experiment 1, 25 experienced karateists learned a new kata using either external or internal visual imagery or stretching. Results indicated that external visual imagery was significantly more effective than internal visual imagery, which was significantly more effective than stretching. In Experiment 2, 40 sport science students learned a simple gymnastics floor routine under one of four conditions: external or internal visual imagery with or without kinesthetic imagery. Results revealed a significant main effect for visual imagery perspective (external visual imagery was best) but no effect for kinesthetic imagery. Experiment 3 employed the same paradigm as Experiment 2 but with high-ability rock climbers performaing difficult boulder problems. Results showed significant main effects for both visual imagery perspective (external visual imagery was best) and kinesthetic imagery. The findings are discussed in terms of the cognitive processes that might underlie imagery effects. Verf.-Referat
