Models for the extrapolation of target\nmotion for manual interception. J Neurophysiol 102: 1491\u20131502, 2009.\nFirst published July 1, 2009; doi:10.1152\/jn.00398.2009. Intercepting\na moving target requires a prediction of the target\u2019s future motion.\nThis extrapolation could be achieved using sensed parameters of the\ntarget motion, e.g., its position and velocity. However, the accuracy of\nthe prediction would be improved if subjects were also able to\nincorporate the statistical properties of the target\u2019s motion, accumu-\nlated as they watched the target move. The present experiments were\ndesigned to test for this possibility. Subjects intercepted a target\nmoving on the screen of a computer monitor by sliding their extended\nfinger along the monitor\u2019s surface. Along any of the six possible target\npaths, target speed could be governed by one of three possible rules:\nconstant speed, a power law relation between speed and curvature, or\nthe trajectory resulting from a sum of sinusoids. A go signal was given\nto initiate interception and was always presented when the target had\nthe same speed, irrespective of the law of motion. The dependence of\nthe initial direction of finger motion on the target\u2019s law of motion was\nexamined. This direction did not depend on the speed profile of the\ntarget, contrary to the hypothesis. However, finger direction could be\nwell predicted by assuming that target location was extrapolated using\ntarget velocity and that the amount of extrapolation depended on the\ndistance from the finger to the target. Subsequent analysis showed that\nthe same model of target motion was also used for on-line, visually\nmediated corrections of finger movement when the motion was\ninitially misdirected.\n<\/p>\n<\/blockquote>\n","protected":false},"excerpt":{"rendered":"<p>John F.
