Document Summary
Lab 3: distance error in visuomotor memory tasks. Research shows that visual cues are essential to accurate motor tasks. 1 this study will look into whether visual delays of a target will impact the performance of hitting said target with an object. I hypothesize that the standard deviation will disperse with visual delays, although the mean will increase slightly. Even though the brain is flexible in adjusting to visual delays, it is still expected that the standard deviation is increased simultaneously. 2 this is due to the likelihood of error range widening. Four participants were asked to stand at a line. 1, 1. 5 and 2 meters away, there was a + made of tape. Participants were asked to look at the + for 2 seconds, followed by closing their eyes. After delays of 0, 5, 10 or 15 seconds, they were instructed to throw an object towards the target.
