BACHETTI, Lívia da Silva; QUAGLIA, Maria Amélia Cesari; ALVES, Arthur  y  OLIVEIRA, Marcos Santos de. The hollow-face illusion in alcohol withdrawal syndrome. Arq. bras. psicol. [online]. 2013, vol.65, n.3, pp.436-451. ISSN 1809-5267.

This research investigated the monocular depth inversion and the depth perception of a hollow-face in individuals with Alcohol Withdrawal Syndrome (AWS) compared to healthy. The study included 15 individuals with moderate and 16 individuals with mild AWS compared to 16 healthy subjects, which judged the mask as concave or convex and attributed to its depth. They were instructed to look with one eye at a concave doll face inside a box. The individuals whit moderate AWS were significantly different from the control group, presenting an impairment on monocular depth inversion of the hollow-face (p<0,05). However, the group with mild SAA made the monocular depth inversion. No differences were found between groups for assignments of the hollow-face depth. The hollow-face illusion was an important tool to investigate the balance between bottom-up and top-down processes during the moderate AWS.
