Generality and specificity of emotion-recognition deficit in schizophrenic patients with positive and negative symptoms.

Schizophrenic patients with positive and negative symptoms, as well as non-patient control subjects, were asked to recognize emotional stimuli of happy, sad, and neutral facial expressions. Dependent measures were the percentage of correct responses, and the incorrect use of an emotion category owing to false recognition. Schizophrenic patients with negative symptoms exhibited a generalized emotion-recognition deficit, and their use of emotion categories during false recognition was random. Schizophrenic patients with positive symptoms showed a deficit in their recognition of 'sad' emotion and were 'positively biased' to the category 'happy' as reflected by its most frequent usage during false recognition.

Visuospatial and affect recognition deficit in depression.

BACKGROUND: Theorists differ in their opinion whether interpersonal difficulties in depression is associated more with perceptual impairment or with emotional bias. The present study intended to resolve such differences of opinion. METHOD: Major depressives, general medical patients, and non-patient controls were administered three visuospatial and two affective tasks to examine the nature of performance deficit associated with each group. RESULTS: Major depressives were found significantly impaired in both visuospatial and affective tasks in comparison to general medical patients, who in turn, were impaired than non-patient controls. CONCLUSION: Major depressives' perceptual deficit is pervasive and not specific to affective categories. LIMITATION: The study could have been more informative if more psychiatric groups had been included as subjects. CLINICAL RELEVANCE: Improvement in depressives' ability for visuospatial and affective tasks may be considered as a marker of their clinical improvement.

Bilateral transfer deficit in schizophrenia: a trait marker.

Schizophrenic patients who had shown improvement over a 6-week treatment period were tested for their bilateral transfer of skill with a mirror-drawing task. Compared with first degree relatives and normal control subjects, patients showed a significant deficit in bilateral transfer of skills in terms of response accuracy both before and after treatment. These findings indicate that the deficit is an enduring functional loss in schizophrenia.
