Feature-Specific
Priming Effects Upon Short Duration Binocular Rivalry

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. Key words; binocular rivalry, priming, feature, attention, awareness |
