Feature-Specific Priming Effects Upon Short Duration Binocular Rivalry

Abstract

‘his study demonstrates that priming stimulation selectively controls the perception of rival binocular inputs (either orthogonal contour rivalry or color rivalry). Four observers participated, two of them for contour rivalry and two for color rivalry. Throughout three experiments, one of the rival image stimuli was presented simultaneously to both eyes or presented to one eye alone for 1 sec. Following the priming stimulation, either immediately or with some interstimulus interval (ISI), the rival test stimuli were presented simultaneously. It was found that observers dominantly perceived the unprimed image when either the test stimulus duration or the ISI was greater than 50 msec. We interpret this to mean that a pre-attentive feature analysis contributes to the priming-induced effects.
