SANTOS, Esther Sampaio et al. The perception of depth or relief of hollow and convex face. Estud. psicol. (Natal) [online]. 2017, vol.22, n.1, pp. 10-16. ISSN 1413-294X.  http://dx.doi.org/10.22491/1678-4669.20170002.

It was investigated the monocular perception of depth or relief of objective concave and convex masks. The study included 40 students, who judge the depth or relief of a concave and a convex mask. More than half of observers, 67%, performed the monocular depth inversion. When asked to evaluate the distance in centimeters from the tip of the nose to the base of the mask, the major extensions were appointed to the convex mask, compared to concave. However, the visual inversion of depth of the concavities was not affected by the position of the masks (vertical or inverted) or by the direction of the light source incident on them (from top or bottom). The results confirm that in the face perception, the top-down process overlaps the bottom-up process and that the hollow-face illusion is an effective instrument in depth perception verification.

Keywords : visual perception; depth perception; facial masks.
