title: Visual-spatial processing and dimensions of schizophrenia: a preliminary study on 62 schizophrenic subjects.
abstract: The aim of the study was to explore the relationships between the performance in figure-ground segregation and the clinical dimensions in schizophrenia. Sixty-two schizophrenic subjects filled out the embedded figures test (EFT) and the schizophrenic symptomatology was rated using the brief psychiatric rating scale (BPRS). The BPRS items were grouped into four categories: positive, negative, general and disorganization. The results showed in male schizophrenics negative and significant correlations between EFT scores and negative or disorganization subscales. Taken into account that in schizotypic subjects EFT scores was negatively correlated with negative dimension of schizotypy we suggested that those relationship could constitute a trait of the disease.
