Openness to experience is characterised by flexible and inclusive cognition. Here we investigated whether this extends to basic visual perception, such that open people combine information more flexibly, even at low-levels of perceptual processing. We used binocular rivalry, where the brain alternates between perceptual solutions and times where neither solution is fully suppressed, mixed percept. Study 1 showed that openness is positively associated with duration of mixed percept and ruled out the possibility of response bias. Study 2 showed that mixed percept increased following a positive mood induction particularly for open people. Overall, the results showed that openness is linked to differences in low-level visual perceptual experience. Further studies should investigate whether this may be driven by common neural processes. 相似文献

Prior knowledge has been shown to facilitate the incorporation of visual stimuli into awareness. We adopted an individual differences approach to explore whether a tendency to ‘see the expected’ is general or method-specific. We administered a binocular rivalry task and manipulated selective attention, as well as induced expectations via predictive context, self-generated imagery, expectancy cues, and perceptual priming. Most prior manipulations led to a facilitated awareness of the biased percept in binocular rivalry, whereas strong signal primes led to a suppressed awareness, i.e., adaptation. Correlations and factor analysis revealed that the facilitatory effect of priors on visual awareness is closely related to attentional control. We also investigated whether expectation-based biases predict perceptual abilities. Adaptation to strong primes predicted improved naturalistic change detection and the facilitatory effect of weak primes predicted the experience of perceptual anomalies. Taken together, our results indicate that the facilitatory effect of priors may be underpinned by an attentional mechanism but the tendency to ‘see the expected’ is method-specific. 相似文献
