Individual differences in the effects of priors on perception: A multi-paradigm approach.

摘要: Abstract The present study investigated individual differences in how much subjects rely on prior information, such as expectations or knowledge, when faced with perceptual ambiguity. behavioural performance of forty-four participants was measured four different visual paradigms (Mooney face recognition, illusory contours, blur detection and representational momentum) which priors have been shown to affect perception. In addition, questionnaires were used measure autistic schizotypal traits the non-clinical population. We hypothesized that someone who ambiguous noisy input relies heavily priors, would exhibit this tendency across a variety tasks. This general pattern then be reflected high pairwise correlations between measures an emerging common factor. On contrary, our results imply there is no single factor explains aforementioned tasks, further evidenced by overall lack robust separate paradigms. Instead, two-factor structure reflecting hierarchy processing best fit for explaining variance these lends support notion mechanisms underlying effects likely originate from several independent sources it important consider role specific tasks stimuli more carefully reporting
