Linking Auditory-Induced Bouncing and Auditory-Induced Illusory Crescents: an Individual-Differences Approach

Abstract When two disks move toward each other, overlap, and then apart, the visual system can resolve ambiguity either as streaming past other or bouncing off other. Presenting a brief beep at moment of overlap has been observed to increase proportion reported impressions (i.e., auditory-induced ) well reduce perceived between (leaving larger uncovered crescent; illusory crescents ). Previous research speculated about relationship both variables, but no direct evidence yet. We present an individual-differences study in which our participants completed / task crescent on consecutive days (to obtain test–retest reliabilities). obtained acceptable good reliabilities for effect tone dependent measures. Most importantly, were correlated moderate range suggesting that illusions are related share common underlying cognitions. Yet, correlations also indicate measures partially capture distinct aspects object correspondence.
