“…The process of pinpointing symmetries in the children's drawings was based on the examination of the pictorial motifs appearing in their pictures. A pictorial motif, in accordance with previous research linked to the analysis of the content of young children's drawings [22,29,47], is considered to be the graphical representation of a certain entity, both physical (e.g., a tree) or abstract (e.g., a decorative pattern), which displays a distinctive level of independence in the picture. Thus, for instance, a flower appearing in a picture is regarded as a pictorial motif as it represents a particular physical entity, which, plausibly, looks to be singled out from the other parts of the drawing.…”
