TL;DR
RT was longer when the response involved significant changes in the temporal organization of the movement pattern, and the hypothesis that the latency of a response is related to the complexity of themovement pattern was only partially supported.
Abstract
Two experiments were conducted in which the latency of movement responses of varying complexity was investigated. The complexity of an arm sweep movement was varied by (a) increasing the extent of movement from 6 in. to 18 in., (b) reversing the movement, and (c) by making two or three pauses in an on-going movement. The results only partially supported the hypothesis that the latency of a response is related to the complexity of the movement pattern. Specifically RT was longer when the response involved significant changes in the temporal organization of the movement pattern.
