LACERDA, Aline Mendes; SIMAS, Maria Lúcia de Bustamante  and  MENEZES, Geórgia Mônica Marques de. Changes in visual size perception in schizophrenia and depression. Psicol. pesq. [online]. 2020, vol.14, n.spe, pp. 140-153. ISSN 1982-1247.  http://dx.doi.org/10.34019/1982-1247.2020.v14.30411.

The objective of this research was to measure possible changes in visual size perception of patients with depression and schizophrenia. Three groups were compared: Control Group (CG), Schizophrenia Group (SchG) and Depression Group (DepG). The diameter of the first figure seen by the participants in each painting was recorded in degrees of visual angle. The SchG perceived images 1.47 larger than CG and the DepG 1.28 larger than CG, whereas SchG selected images 1.15 larger than DepG, F (2, 57) = 17.677, p < .0001. These findings suggest there are changes in visual size perception related to depression and schizophrenia.

Keywords : Schizophrenia; Depression; Visual perception; Size perception.
