Our results manifested that performance of patients with schizophrenia was statistically lower in test of intelligence; there were no differences in memory test, even though certain trends to lower performance we found in patients with schizophrenia; in the test of executive functoins there was a statistically significant difference in dimension of Conceptual level responses, in other dimensoin there was no difference, but patients with depression had inferior performance; in the verbal fluency test there was no statistically significant difference between both groups, patients with schizophrenia had lower performance; attention – there was no statistically significant difference between both groups, worse performance we found in patients with schizophrenia; statistically significant difference was found in reaction time on both stimuli, visual and auditory stimulus, when markedly worse performance was found in patients with depression.
