A comparison of basic and social cognition between schizophrenia and schizoaffective disorder.
We compared basic and social cognition in individuals with schizophrenia and schizoaffective disorder. 199 individuals with schizophrenia and 73 with schizoaffective disorder were compared on measures of executive function, verbal and nonverbal memory, and processing speed, as well as two measures of social cognition, the Hinting Task and the Bell Lysaker Emotion Recognition Task. The samples did not differ significantly on the basic cognitive measures, however individuals with schizoaffective disorder performed significantly better than those with schizophrenia on the Hinting Task, a measure of Theory of Mind. Results provide limited support for a taxonomic distinction between the two disorders.
