| Visual perception is not merely determined by the current sensory stimulus, it is also influenced by previous visual decisions. History effects in visual perception have been demonstrated with adaptation and the resulting after-effects, with implicit perceptual memory influencing binocular rivalry and ambiguous figures, with sequential effects from past trials in repetitive decisions, and with implicit learning of visual statistical regularities. Recently, we found that stimuli presented 10 minutes in the past can also influence the current perceptual decision (Chopin & Mamassian, 2012, Current Biology). For instance, seeing more often a stimulus with an orientation A rather than B several minutes ago introduces a bias to perceive the orientation A, while seeing more often A a few seconds ago produces the opposite bias. We believe that the monitoring of remote history statistics contributes to the recalibration of the visual system. This proposal is discussed in the context of the other history effects in visual perception. |
