A critical issue for Ericsson et al.'s proposal is the development of a fully adequate description of neurophysiological substrates for deliberate practice. Ericsson et al. do provide two substantial subsections on biological substrates--namely, their subsections, "Acquisition of superior power, control, and speed of motor activities" and "Improvement in the selection of actions in representative situations". However, as it stands, these discussions do not adequately explain the remarkableness of giftedness. To get at the details of the subtle effects of deliberate practice, Hesheng Liu and Larry R. Vandervert recently proposed a thoroughgoing neurophysiological explanation of the child prodigy. Their explanation is based upon the "collaboration" of working memory and cognitive functions of the cerebellum. In their approach all "repetitive" working memory processes taking place in the cerebral cortex (e.g., in deliberate practice) are "adaptively modeled" in the cerebellum. When the resulting cerebellar control models are fed back to working memory areas of the cortex, the thought processes of working memory become faster, higher in attentional control, and more appropriately and optimally timed. The above newer role of the "cognitive cerebellum" offers needed detailed support for Ericsson et al.'s proposal. (Contains 1 note.)
