정신분열증과 우울증의 지각결핍의 비교

A Comparison of Perceptual Deficit between Schizophrenic and Depressive Patients

The perception of stimuli with two dimensions (size and figure) was investigated using Garners card sorting method into schizophrenic and depressive patients. The comparison of three performance indices (redundancy, filltering, scanning) between two study groups revealed that 1) the analysis of variance of the corrected time shows no significant difference between two groups, 2) in redundancy and filtering sorting the subtractive and ratio indices show no significant difference between two groups, 3) in scanning sorting the depressive group shows significantly longer sorting time than schizophrenic group (p < 0 ,01 in subtractive index, p > 0 .05 in ratio index). The above findings suggest that the previously known perceptual deficit (mainly filtering deficit) may not be specific only to schizophrenia.
