There is an ongoing debate on the effects of stimulus history on perception. Recent studies have shown that repeated perceptual decisions to similar stimuli lead to contextual effects, correlated both negatively with the past (negative aftereffects) and positively (serial dependence), sometimes at the same time (Chopin and Mamassian, Current Biology, 2012; Fritsche et al., Current Biology, 2017). However, less attention has been given to understanding how these effects evolve for stimuli further in the past. This task can be challenging because the effect is weak and difficult to dissociate with that of the very recent history. I will present a relevant study from my PhD as well as the ongoing work in the lab that investigates the effects of stimulus history on perception at different timescales.
