When the eyes track a moving object, the image of a stationary target shifts on the retina colinearly with the eye movement. A compensation process called position constancy prevents this image shift from causing perceived target motion commensurate with the image shift. The target either appears stationary or seems to move in the direction opposite to the eye movement, but much less than the image shift would warrant. Our work is concerned with the question of whether position constancy operates when the image shift and the eye movement are not colinear. That can occur when, during the eye movement, the target undergoes a motion of its own. Evidence is reported that position constancy fails to operate when the direction of the target motion forms an angle with the direction of the eye movement. In 1978, Wallach, Bacon, and Schulman raised the following question: Is the induced motion that is perceived when the eyes track the moving surround instead of looking at

Videotapes of two naturalistic events, a basketball-like game and a vocalizing human face, were presented in a dual-task situation, with subjects responding to target events in individual episodes. The fact that the stimulus episodes consisted of natural motions permitted subjects to base their attention on the partially determinate structure that characterizes such motions. Simultaneous visual presentations were in full transparent overlap. the auditory presentations were overlapped spatially. Performance on the dual task improved significantly in all experimental conditions over two days of practice. Performance approached control-group ceiling levels for events available to different modalities (hearing and sight). When information was available only in a single modality, performance was lower over-all, but practice effects were still significant. The results are discussed in the context of a cognitive skills approach to attention.
