Abstract
Human observers can accurately recognize visual stimuli presented during 100 ms in rapid serial visual presentation (RSVP). However, the repetition of a given stimulus can decrease its detection and report. This phenomenon, called repetition blindness (RB), has been found for linguistic stimuli, drawings, silhouettes and familiar faces (Mondy and Coltheart 2004). Here we report one RSVP experiment dealing with pictures of natural objects: three natural objects with three points of view over the same natural background were used for a recognition task with RSVP (two pre-experiments were designed to measure duration thresholds for single objects in a recognition task). Observers had to estimate the number of apparition a given object they had seen in a sequence. Results were valued in term of correct responses to compute the repetition blindness rate. A non parametric signal detection analysis (A′ and B″) was also computed (Arnell and Jolicoeur 1997).
RB was found with pictures of objects within a natural background. Results also showed viewpoint invariance, in agreement with Kanwisher (Kanwisher, Yin et al. 1999). These data are discussed in the light of Chun's dual theory (Chun and Potter 1995) and current models of object recognition (Biederman and Gerhardstein 1993; Tarr 2004).
