Abstract

The aim of the reported study was to determine whether the ability to segregate a simple figure embedded in a complex visual ground, was associated with psychotic-like features in a sample of undergraduate students. The participants (N =100) were tested on the Hidden Figures Test, as well as the Raven’s Progressive Matrices, and completed a multi-dimensional schizotypy inventory (O–LIFE). The IQ scores were positively related to the number of correct responses on the Hidden Figures Test, but were unrelated to any of the schizotypy measures. Impaired Performance on the Hidden Figures Test was associated with negative schizotypy (‘Introvertive Anhedonia’), and enhanced performance was associated with the ‘Impulsive Non-Conformity’ scale. Performance on the Hidden Figures Test was independent of the positive (‘Unusual Experiences’), and the disorganized (‘Cognitive Disorganization’), schizotypy. The results are discussed in terms of a putative involvement of the frontal lobes in the negative symptomatology of schizophrenia, and in top-down (goal-driven) perceptual processing, as well as the possible compensatory functional aspect of impulsivity in terms of allocating attention.
