Visual Performance

Watson, Derrick G. & Humphreys, Glyn W. (Feb.-June 1999). Segmentation on the

Basis of Linear and Local Rotational Motion: Motion Grouping in Visual Search. Journal of Experimental Psychology: Human Perception and Performance, Vol. 25, No. 1, 70-82.

Have you ever layed on the ground and watched a fan moving on the ceiling above you? I used to try to watch just one spoke of the fan and try to follow it around the circle for as long as I could. The article I picked on motion grouping in visual search is somewhat like the game I used to play as a child.

Five experiments were conducted. In experiments one to three similar experiments were conducted. The experiment was done on a computer screen with a program written specifically for the experiment. The computer monitors showed a horizontal rotating target with H's all over it. Next, they added a T among the H's to see if the subjects co


Experiment four used a vertical rotating target. The T moved upward against the H's and T's. Instead of rotational movement in experiments one through three, experiment four used translational motion. The letters moved to their positions across the computer screen instead of revolving around a target. The letters would move either to the top or the bottom of the screen then once they reached their destined position they would all jump back into their original starting position and start moving again. In the experiments, subjects would find the T before it ever jumped back to the starting position.

Experiment five had another approach to the experiment. This time the rotating target was again used with a clockwise rotating T, moving against the distracters which were counterclockwise rotating H's and upward moving T's.

uld distinguish the T among the H's. Then, the T moved counterclockwise
