G. Bryson et al., AFFECT RECOGNITION IN SCHIZOPHRENIA - A FUNCTION OF GLOBAL IMPAIRMENTOR A SPECIFIC COGNITIVE DEFICIT, Psychiatry research, 71(2), 1997, pp. 105-113
To investigate cognitive variables related to affect recognition in sc
hizophrenia, 63 subjects with DSM-III-R diagnoses of schizophrenia or
schizoaffective disorder were administered a test battery which includ
ed the Bell-Lysaker Emotion Recognition Task (BLERT), Wisconsin Card S
orting Test (WCST), Wechsler Memory (WMS-R) and Adult Intelligence Sca
les (WAIS-R), Hopkins Verbal Learning Test, Gorham's Proverbs, and Con
tinuous Performance Task (CPT). Coefficients revealed a moderate relat
ionship between emotion recognition and WCST and CPT but no significan
t relationship with other test variables. Multiple regression analysis
demonstrated that approximately one-third of the variance in BLERT sc
ores could be explained by cognitive variables including the Digit Sym
bol Subtest, CPT, and Hopkins Verbal Learning Test. Other analyses dem
onstrated that subjects with moderate to severe affect recognition imp
airment had more perseverative errors, had fewer complete categories a
n the WCST and had more errors on the CPT. However, there were no sign
ificant differences on global measures of impairment such as WAIS-R IQ
s and Digit Symbol Substitution Test. The discussion focuses on defici
ts in affect recognition as a distinct feature which contributes to th
e heterogeneity of the disorder. (C) 1997 Elsevier Science Ireland Ltd
