These are pressures to assimilate cultural artifacts, norms, roles, and behavioral scripts. The playful and creative elements in both forms of pretending are dictated by the variable, open-ended, and evolving nature and function of the cultural tasks they handle. The resulting creativity of the adult intellect is likely to be a distant and indirect by-product of temporary and specific ontogenetic responses to temporary and specific ontogenetic challenges, particularly cultural ones
