Abstract
A series of experiments is described which uses a perceptual matching approach to study the effect of exogenous visual cues on perception of static and dynamic stimuli. Analogous experiments were carried out for orientation judgments of rotated Gabor patches and for direction of motion of coherent dot motion. Response time effects of cuing were found in all conditions. Cuing was found to improve accuracy of orientation judgments, while the effects on motion judgments were less reliable. Cuing was found to have substantially larger effects on quality of orientation judgments at low contrast levels. Other analyses performed found sequential trial effects and qualitatively different effects of canonical directions on orientation and motion judgments.
