Twenty Ss wore a 20 diopter displacement prism while they practiced tracking a moving target and when they performed a second task requiring location of a stationary target. Results showed significant transfer of adaptation effects to performance on the second task, and showed a limited aftereffect upon removal of the prism. Massed and distributed practice on the tracking task produced differences in tracking performance, but no differences in the amount of transfer or in the aftereffect. Ten control Ss showed no adaptation and no aftereffect. Author
