This study examined two different cues that might be used in the reproduction of movement: (1) the initial position of the movement and (2) the terminal location of the mouement. An experiment was designed to assess the relative importance of these two cues using the kinesthesia subtest of theSouthern California Sensory Integration Tests with 48 college juniors. A 2 x 2 factorial design was used One factor, speed of mooement; had two levels, fast and slow, as did the otherfactor, angle of approach-altered approach or originalapproach. The dependent measures were distance error from the target and angle error. The results suggestedThe authors wish to thank the subjects for their participation and cooperation and Cheryl Fontane and Rosalie Williams for their competent and patient technical assistance.

Schwartz (1984) in his commentary on our article concluded that the authors had "... not provided reliable and valid evidence to justify conclusions at this juncture." These conclusions were (1) that the target point of the movement was the most important cue for movement accuracy, and (2) that rapid movements produce greater errors in direction than do slow movements. We would first like to address Schwartz'S criticisms and then point out why, from a motor control theoretical standpoint, the endpoint or location point of a movement is essential.Schwartz brought up a number of criticisms of our article. Some of these criticisms we consider valid, have relevance to our conclusions, and therefore need to be addressed in detail. Two other criticisms were minor and have little bearing on the outcome of our study. We will address these minor criticisms first. One minor criticism concerned the operational definition of starting point and endpoint. We feel that not only are starting
