Movement Speed and Refractoriness.
Williams, Leslie R. T.; Sullivan, S. John
The refractoriness of an extended arm swing to reversal was studied using three speed conditions (maximal, 2/3 of maximal, 1/3 of maximal). Twenty-two college males were the subjects. Interstimulus intervals (ISIs) ranged from .10 to .50 seconds with catch trials being used to minimize any tendency to anticipate the reversal signal. While reaction time to the reversal signal, (Reversal multiplied by Time sub-two) increased consistently under all speed conditions as ISI decreased, the trends were not adequately explained by single-channel theory since there appeared to be some extra delay that increased with ISI. Interpretation favored a composite model incorporating peripheral considerations. (Author)
