This article discusses the neo-Piagetian theories of cognitive development proposed by Robbie Case, Andreas Demetriou and Anastasia Efklides, Kurt Fischer, Jeffrey Farrar, Graeme Halford, Juan Pascual-Leone, Michael Shayer, and Robert Siegler. Each theory is discussed in terms of its basic assumptions, and propositions regarding structure, process, novelty and automatization, context, and mechanisms of development. Then some general conclusions are drawn about the enterprise of neo-Piagetian theorizing as a whole. 相似文献

Although meditation is increasingly being employed as an adjunct in psychotherapy, there has been practically no comprehensive evaluation of its usefulness in this respect. This paper seeks to address this issue through conceptual models of the meditation experience. It is concluded that meditation practice may be associated with the acquisition of some useful skills (e.g., focused attention), that practice may be physiologically relaxing, that meditation may decrease anxiety, insomnia and drug usage, while enhancing hypnotic induction and self-actualization. There is still no compelling evidence, however, that meditation practice is associated with unique state effects compared with other relaxational procedures. Those who appear to benefit most from meditation appear to be those who present with milder disorders. The clinical value of meditation, therefore, appears to be limited. Furthermore, the long-term objectives of meditation are not in general congruent with those of mainstream psychotherapy, as they go beyond therapeutic gain in the clinical sense. 相似文献

We have identified a fundamental property of human motor behavior as a tight coupling of the curvature-speed relationship in the reaching movements of 5- to 9-month-old infants. This relationship termed a movement unit, occurs regardless of the distance of duration of the reach and in spite of the developmental change that occurs in grasping during this period. Movement unit durations are tightly clustered around 200 ms regardless of overall duration or distance or the position of the unit in the reach. The curvature-speed coupling has been identified by others in adult reaching and handwriting. Models of biological motor control must account for this invariant relationship. 相似文献
