The Salience of Visuospatial and Organizational Skills in Reproducing the Rey-Osterreith Complex Figure in Subjects with High and Low IQs

Abstract

The salience of visuospatial and organizational skills in copying the Rey-Osterreith Complex Figure (ROCF) was examined in 44 adults diagnosed with Attention Deficit Hyperactivity Disorder (ADHD). Subjects were divided into a high average and above IQ group (n = 21) and an average and below IQ group (n = 23). Multiple regressions were conducted for both groups, with the ROCF copy as the dependent variable and WAIS-R Block Design and Stern Fragmentation scores as predictor variables. Results indicated that, for the high IQ group, visuospatial skills were more salient in predicting ROCF copy scores. By contrast, for the low IQ group, organizational skills were more salient for predicting ROCF copy score. Our findings are discussed in relation to the Boston Process Approach.
