A psychophysically-tuned computational model of human primary visual cortex produces geometric optical illusions.

ABSTRACT: Geometric optical illusions (GOIs) are mismatches between physical stimuli and perception. GOIs provide an access point to study the interplay between sensation and perception, Yet, there is relatively scant quantitative investigation of the extent to which different GOIs rely on similar or distinct perceptual mechanisms, which themselves are driven by specific physical properties. We addressed this knowledge gap with a combination of psychophysics and computational modelling. First, 30 healthy adults reported quantitatively their perceptual biases with three GOIs, whose physical properties parametrically varied on a trial-by-trial basis. A given physical property, when considered in isolation, had different effects on perceptual biases depending on the GOI (e.g. the spacing of stimuli aff
