dc.description.abstractThe proposed study will examine the relationships among object weight and size, grasp preparation, handedness, and the detection of change in the perception of visually displayed objects. In a 4 X 2 factorial design, approximately eighty subjects will be randomized into one of four conditions. Subjects will be instructed to grasp one of four differently sized and weighted balls: a large, heavy ball; a large, light ball; a small, heavy ball; and a small, light ball. All subjects will be grasping a ball while participating in a change-detection task, in which subjects will watch a computer screen while two slightly differently images flicker back and forth. Once they have detected the object that has changed, they will press a key and select the object, which the subjects perceived to have changed. They will complete 12 of these trials. The grasping conditions are the independent variables, and the change-detection task is the dependent variable. We hypothesize that change detection will improve for conditions in which the grasped object's weight—as well as its size—is congruent with the changed-object will perform significantly better at change-detection than when object weight is incongruent.
