Abstract
Fifty-six Ss responded in a paper-and-pencil figure-cancellation task to 4-by-4 metric figures. Both random and constrained or “Redundancy-I” figures were used with both rotated and nonrotated choice figures. In terms of speed and accuracy of cancellation, perceptual performance with random figures was better than with constrained, and performance with nonrotated choice figures was better than with rotated. A significant interaction of figure type with rotation indicated that the detrimental effects of choice-figure rotation were especially large when imposed on constrained figures. The effect of choice-figure rotation is interpreted as similar to other “noise” effects that make filtering a necessary part of S’s task.
