title: Influence of practice with within-trials and inter-trials changes of target velocity in improving movement correction.
abstract: In the present study, the influences of two practice methods on movement correction during interceptive action was examined. Fourteen men practiced intercepting a moving virtual target. One group practiced on a target that changed velocity from 4 to 8 m/sec. during the trial (within-trials change group). The other group practiced under Slow and Fast conditions, in which the initial velocity (4 or 8 m/sec.) remained constant (inter-trials change group). After the practice, both groups showed similar decreases in temporal errors in interception of an acceleration target. However, the within-trials change group showed non-corrected movements, whereas the inter-trials change group showed corrective movements. Thus, the practice methods for within-trials and inter-trials change resulted in different corrective strategies to acceleration target.
