Convexity Bias and Perspective Cues in the Reverse-Perspective Illusion

Abstract: The present experiment was designed to examine the roles of painted linear perspective cues, and the convexity bias that are known to influence human observers’ perception of three-dimensional (3D) objects and scenes. Reverse-perspective stimuli were used to elicit a depth-inversion illusion, in which far points on the stimulus appear to be closer than near points and vice versa, with a 2 (Type of stimulus) × 2 (Fixation mark position) design. To study perspective, two types of stimuli were used: a version wit… Show more

“…The boundaries between convex and concave surfaces are important for identifying components of objects (Biederman, 1987;Koenderink & van Doorn, 1982). There is an overall bias for perceiving objects as convex, as in "hollow-face" and "hollowpotato" illusions (Dobias et al, 2016;Gregory, 1970;Hill & Bruce, 1994;Hill & Johnston, 2007;Langer & Bülthoff, 2001), which appears even in 6-month-old infants (Corrow et al, 2014). A bias for convexity has also been shown with 3D "polycube" stimuli (consisting of random configurations of 10 individual cubes), where participants rated the likelihood that they would perceive a polycube as an object (Wörgötter et al, 2015).…”

“…Thus, one may think of 'isomorphism' as meaning 'same form' or 'same structure'. 5 At this stage, what we mean by 'structure', is not completely clear. The isomorphism used in Section 3.4 preserved the algebraic structure, but there are other types of structure; topological, order-theoretic, geometric, metric, combinatorial, etc.…”

“…2) The presence of concavities: The complex reverspectives of Figure 2 and the right panel of Figure 1 contain both concavities and convexities, unlike the simple piece of the left panel of Figure 1 that is purely convex. Concave spaces are more likely to produce depth inversion-and the concomitant paradoxical motion-because humans have a bias to perceive objects as convex [25][26][27]. This bias favors perceiving the convex "Sticking-out Room" as convex, thus weakening the depth-inversion illusion.…”
