Practicing with Gradual Increases in Contextual Interference Enhances Visuomotor Learning
نویسندگان
چکیده
The purpose of this study was to determine if practicing with gradual increases in contextual interference (CI) facilitated the learning of a continuous motor skill that required visuomotor tracking. We hypothesized the group that practiced with increasing amounts of CI would perform significantly better on a retention and transfer test compared to participants that practiced with blocked and random scheduling. A total of 78 participants were randomly assigned to one of three groups (i.e. Blocked, Increasing, Random). The level of CI was modified by varying the number of revolutions per minute (RPM) on a rotary pursuit tracker. Following the acquisition phase, participants returned after a 24-hour period and completed the 12-trial retention and transfer test. The results of statistical analysis indicated that all three groups improved their performance during practice. The posttest analysis indicated the Increasing group was better than the Blocked and Random groups on the retention and transfer test.

متن کاملMotor learning and consolidation: the case of visuomotor rotation.
Adaptation to visuomotor rotation is a particular form of motor learning distinct from force-field adaptation, sequence learning, and skill learning. Nevertheless, study of adaptation to visuomotor rotation has yielded a number of findings and principles that are likely of general importance to procedural learning and memory. First, rotation learning is implicit and appears to proceed through r...
