![]() Importantly, final copy accuracy was found to be associated with all of these aspects of drawing. Correlational analyses provided indications of their validity by showing that spatial, procedural, and kinematic scores were associated with constructional, organisational and motor measures of drawing, respectively. Accordingly, a composite score for each dimension was determined. ![]() Principal component analysis of the T-RCF indices was performed, identifying spatial, procedural and kinematic components as distinct dimensions of drawing execution. A subgroup of 35 participants also completed a paper-and-pencil drawing battery from which constructional, procedural, and motor measures were obtained. We have also analysed the structure of relationships between these indices and provided insights into the constructs that they capture. This system extracts 12 indices capturing various dimensions of drawing abilities. In this study, we have implemented a novel Tablet-based assessment, acquiring data and information for the entire execution of the Rey Complex Figure copy task (T-RCF). Nevertheless, these aspects are not taken into account in conventional scoring methodologies. However, drawing tasks also involve other cognitive and motor abilities, which may influence the final graphic produced. Accuracy in copying a figure is one of the most sensitive measures of visuo-constructional ability.
