Is interpolation cognitively encapsulated? Measuring the effects of belief on Kanizsa shape discrimination and illusory contour formation

Abstract: Contour interpolation is a perceptual process that fills-in missing edges on the basis of how surrounding edges (inducers) are spatiotemporally related. Cognitive encapsulation refers to the degree to which perceptual mechanisms act in isolation from beliefs, expectations, and utilities (Pylyshyn, 1999). Is interpolation encapsulated from belief? We addressed this question by having subjects discriminate briefly-presented, partially-visible fat and thin shapes, the edges of which either induced or did not indu… Show more

“…The current data obviously cohere well with these results: our clinical participants automatically formed illusory contours, but were less able to use those contours to differentiate shape. This two-stage model of Kanizsa shape discrimination is also consonant with a previous behavioral study, as noted (Keane, Lu, et al, 2012). …”

“…The trial presentation sequence (Figure 1B) was similar to earlier studies (Keane, Lu, et al, 2012; Ringach & Shapley, 1996; Zhou, et al, 2008) and consisted of a 1000 ms black screen, a 200 ms target presentation, a 50 ms uniform black screen, and 300 ms mask (to cap stimulus processing time). Another black screen would linger until a response, after which an auditory beep sounded for a correct answer.…”
