PURPOSE
We investigated the effects of dominant eye and contextual background on predominance during binocular rivalry. METHODS: 10 subjects were recruited for the present study. Dominant eye was determined using the hole-in-the-card test. In experiment 1, subjects viewed the stimuli through anaglyph filters and reported the predominance of color. The subject's responses were compared with the color on the dominant eye. To investigate the influence of color dominance and contextual color, we conducted the experiment with added contextual color information target through switched-anaglyph filters. In experiment 2, the subject viewed the stimuli through the polarized filters and reported the predominance of orientation. The subject's responses were compared with the grating on dominant eye. To rule out the effect of stimulus size, we conducted the experiment with a smaller target. We designed the additional experiment to investigate the influence of contextual grating information on binocular rivalry. RESULTS: 10 subjects were evaluated. In experiment 1, 8 of 10 subjects reported that eye preference was highly correlated with dominant eye. This finding is significant without reference to color. In experiment 2, 7 of 10 subjects reported that eye preference was highly correlated with dominant eye. This finding is significant without reference to size. In experiment 1-2 and 2-2, all subjects reported that predominance of context contradictory target increased. CONCLUSIONS: We found the relationship between the dominant eye and eye preference. Experiment 1-2 and 2-2 showed that contradictory contextual information increases target predominance during binocular rivalry. Overall, our results indicate that the contextual background reduce the stimulus strength of the context-congruent target; it would correspond to an increase in the dominance duration of the context-contradictory target. |
