Drawing Skills

AbstractTechniques used in cave art suggest that drawing skills emerged long before the oldest known representative human productions (44,000 years bc). This study seeks to improve our knowledge of the evolutionary origins and the ontogenetic development of drawing behavior by studying drawings of humans (N = 178, 3- to 10-year-old children and adults) and chimpanzees (N = 5). Drawings were characterized with an innovative index based on spatial measures which provides the degree of efficiency for the lines that are drawn. Results showed that this index was lowest in chimpanzees, increased and reached its maximum between 5-year-old and 10-year-old children and decreased in adults, whose drawing efficiency was reduced by the addition of details. Drawings of chimpanzees are not random suggesting that their movements are constrained by cognitive or locomotor aspect and we cannot conclude to the absence of representativeness. We also used indices based on colors and time and asked children about what they drew. These indices can be considered relevant tools to improve our understanding of drawing development and evolution in hominids.

To analyse or experience history, to argue or narrate it, two approaches define and explain the phenomenon of thinking about history. In recent decades, thinking about history has become especially relevant because of its relationship with citizenship, either to evaluate evidence of the past or to guide present and future action. The contributions of psychology are diverse and come from traditions that refer to apparently antagonistic psychological processes, such as narrative and argumentation. The objective of this article is to address this discussion from a cultural–historical approach, specifically Vygotskian. We propose that argumentation and narrative are psychological processes that can be developed separately in ontogeny. Both processes, under certain conditions and socially mediated action, are stressed and articulated to give way to historical thinking, a higher psychological process.
