LAB 2 CONTROL OF REACHING 2008 Each group should pick one of the following 2 experiments. You will need data for at least 1 observer, but ideally each student should do the experiment (which doesn’t take very long). 1.Latency of visuo-motor feedback loop. Measure reaction time to a change in object position during a reach. Observer makes 5-10 practice reaches from yellow disk in front of workspace to pick up cube at back of workspace. Experimenter says GO. Reach at normal speed (try to keep constant). Pick up cube, put it down, and return to starting point. After an unpredictable number of trials the experimenter will move the object to a random location during the reach. The observer must correct the reach to pick up the cube. Do 10 such trials, 5 of which have a displacement, 5 don’t. Record data for last 2 practice trials and the 10 experimental trials. Analysis: Plot XY trajectory in the plane of the table. Indicate point where displacement occurred, and point where change in trajectory is evident. The difference in these times is the visuo-
