Finding of abnormal scanning behavior in the Span of Apprehension task in schizophrenia but diagnostic non-specificity of sum scores.
Deficits in the Span of Apprehension (SOA) task have been discussed controversially as a trait marker of schizophrenia. The task was administered to 47 schizophrenia and 48 depressed patients as well as to 46 controls. Results indicate a non-specificity of the SOA sum scores but differential abnormalities in spatial visual processing.
