The effects of response amplitude and terminal accuracy on 2-choice reaction time (RT) and on movement time (MT) were studied. Both the required amplitude (A) of a movement, and the width (W) of the target that S was required to hit, had a large and systematic effect on MT, whereas they had a relatively small effect on RT. Denning an index of movement difficulty as ID = logi 2A/W, the correlation between ID and MT was found to be above .99 over the ID range from 2.6 to 7.6 bits per response… CONTINUE READING
