La investigación cognitiva del síndrome esquizofrénico

Abstract

This review provides a perspective of cognitive disturbances found in schizophrenia and, particularly, of deficits found in several automatic and controlled processes: information filtering, attention and vigilance, concept formation and memory. Several experimental paradigms employed in the study of central executive processes are also described; and, finally, a cognitive model of abnormal behaviours and clinical symptoms of schizophrenia (delusions, disorganization, hallucinations, and the loss of a sense of personal identity) are outlined suggesting that they may be linked to a basic disturbance in comprehensive knowledge or context perception.
