A battery for the assessment of visuo-spatial abilities involved in drawing tasks.
Drawing ability is a complex cognitive process that involves different aspects of visuo-spatial skills. To date, the link between these functions has not been deeply investigated because of the absence of a standardized test that globally analyzes the basic aspects of visuo-spatial processes. The aim of this study was to examine the dimensionality, reliability, and validity of a new battery assessing basic visuo-spatial abilities implied in drawing tasks. A total of 370 children (aged 4-11 years) participated in the study. In order to analyze the psychometric properties of the battery subscales, data were analyzed with a Rasch model and compared with other standardized tests. For each subscale items were compared and ordered on the latent trait, and the misfitting items eliminated. The results of this study provide evidence for the reliability and validity of the battery, and indicate that the battery can be a valid tool for researchers interested in investigating the development of visuo-spatial abilities and the relationship between basic visuo-spatial abilities and general cognitive abilities.
