| Abstract: | Abstract Four groups of 20 subjects were given 35 practice trials on a discrete motor task. On Trials 3 through 25 each of three experimental groups performed with either a 1, 3, or 6 lb. wristlet strapped to their wrists. Trials 1 and 2 and Trials 26 through 35 were performed under control conditions. Comparisons made of the three experimental groups with a group which practiced under control conditions throughout, revealed that the added physical work significantly depressed performance but did not affect learning. Analysis of the data after rest revealed that the groups did not differ significantly in the amount of learning, slopes of the curves, or means of the test trials. Reminiscence was found to be a function of the amount of physical work. |
