Filling-in and contour interpolation in Kanizsa figures
Siyi Chen · OSF Preprints (OSF Preprints) · 2017
To explore the mechanisms of object integration in the human visual system, the present study investigated how completion of illusory contours and surfaces in Kanizsa figures modulates the sensitivity of localizing a target probe. In three experiments, observers determined whether a briefly presented dot probe was located inside or outside a region demarcated by ‘pacman’ stimuli that induce variants of an illusory Kanizsa figure. Performance in this dot-localization task was then used to determine psychometric functions, with their discrimination threshold characterizing the detection sensitivity.
