AbstractWe propose a unified explanation of contrastive and assimilative adaptation aftereffects from the perspective of higher-level cognitive processes: rational category learning and categorical perception. We replicate (twice) previously reported assimilative and contrastive effects (Uznadze illusion in visual modality), propose a rational computational model of the process, and evaluate our model performance against the Bayesian logistic regression baseline. We conclude by discussing theoretical implications of our study and directions for further research.
