Background: Theorists differ in their opinion whether interpersonal di
fficulties in depression is associated more with perceptual impairment
or with emotional bias. The present study intended to resolve such di
fferences of opinion. Method: Major depressives, general medical patie
nts, and non-patient controls were administered three visuospatial and
two affective tasks to examine the nature of performance deficit asso
ciated with each group. Results: Major depressives were found signific
antly impaired in both visuospatial and affective tasks in comparison
to general medical patients, who in turn, were impaired than non-patie
nt controls. Conclusion: Major depressives' perceptual deficit is perv
asive and not specific to affective categories. Limitation: The study
could have been more informative if more psychiatric groups had been i
ncluded as subjects. Clinical Relevance: Improvement in depressives' a
bility for visuospatial and affective tasks may be considered as a mar
ker of their clinical improvement. (C) 1998 Elsevier Science B.V.
