Evaluation Using Polar Coordinate of the Representation of Movement in the Drawings of Children Aged 5 to 8 Years

Abstract

The progressive complexity of mental representation is the basis for changes in human cognitive development. Evaluation of its external manifestations as graphic representation in drawings could be an instrument to understand changes in cognitive development and representational complexity. The aim of this study is to evaluate the appearance and role of the indicators used by children to represent moving figures in their drawings. This allows us to know the continuum from its non-manifestation to full expression through the vectorial interrelationships of the graphic indicators in each of the ages studied. Participants were n = 240 children from 5 to 8 years old; their drawings of two moving figures were analyzed, applying the polar coordinate technique. Results show a map of interrelations among the graphical movement indicators and changes in the drawing elements in an increasing continuum of complexity and the roles conferred to figures sketched. The conclusion is that changes evaluated in drawings can interactively reflect mental representation, and they could promote its transformation. The applied transfer of the results to education is discussed, in order to optimize the representational complexity and cognitive development.
