Watson Derrick G Humphreys Glyn W FebJune 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 Hs all over it Next they added a T among the Hs to see if the subjects could distinguish the T among the Hs Then the T moved counterclockwise against all the clockwise moving Hs and the scores of the subjects again were recorded After that they put multiple Ts and Hs on the rotating target and had the subjects try to find the one T that was moving against the other distracters counterclockwise Experiment four used a vertical rotating target The T moved upward against the Hs and Ts 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
