Much has been learnt by examining how adaptation to displaced visual feedback about the position of the hand transfers to new positions and tasks. We examined adaptation to delayed visual feedback about the hand. We showed that people readily learn to intercept moving targets with a cursor that follows the hand with a delay of up to 200ms. Targets moved in different directions at different speeds, so people could not just learn to make specific movements. Adaptation transferred to movements starting at a different distance from the target. Moreover, having to pass through a moving gap to reach the moving target did not disrupt the adaptation. However, there was no transfer to lifting the hand as soon as the same target reached an indicated position, to moving the hand to arrive at a similar static target in synchrony with the third of three tones that were presented at equal intervals, to moving the hand to a static target through a moving gap, or to pursuing a moving dot with the unseen hand. Thus, adaptation to a temporal delay is task specific and can transfer to new circumstances but not to different tasks.
