The development of context sensitivity in children’s graphic copying strategies

The authors report on a series of 5 experiments in which 462 5- to 10-year-old children and 109 adults were required to copy geometric figures either with no constraints or following prior exposure to primes consisting of different parsings of the figures. The analysis focused on the graphic strategies adopted by the participants to copy the models. Three developmental steps were revealed in the baseline copying condition. Priming experiments demonstrated that the age-developmental step correspondence varied as a function of the type of prime used. However, the impact of priming differed according to age. It was limited at 6 years, whereas its size was noticeable at the other ages. These results are discussed in the light of developmental models that hypothesize a major role either for endogeneous factors in cognitive development or for exogeneous and contextual factors.
