Analysis of complex strategies usage in persons with intellectual disability in a visuoconstruction context

The goal of the study was to assess planning ability, in a visuoconstruction context, of a group of people with intellectual disability. The 70 participants were members of Aura Foundation diagnosed with moderate intellectual disability and were recruited by intentional sampling. Significant correlations were found between the nonverbal intellectual quotient, evaluated using the Raven Progressive Matrices, and the richness and accuracy of the Rey Figure drawing and between the nonverbal intellectual quotient and the type of creation of the figure. Participants with higher intellectual quotient scores were found to perform better task planning. A significant correlation was also found between the richness and accuracy of the Rey Figure and the type of creation used. These results demonstrate the importance of a support system that impulses the usage of complex strategies to achieve goals.
