The present research involved gauging preschoolers’ learning potential for a key arithmetic concept, the addition–subtraction inverse principle (e.g., 2 + 1 − 1 = 2). Sixty 4- and 5-year-old Taiwanese children from two public preschools serving low- and middle-income families participated in the training experiment. Half were randomly assigned to an experimental group; half, to a control condition. Participants were tested for an understanding of inversion before and after intervention. One-third of the 5 year olds from both groups performed at the marginally or reliably successful levels before the intervention, and three quarters of them did so in the posttest. Only one of the 4 year olds was marginally successful before the intervention and 4 year olds in the experimental group somewhat benefited from the intervention. Significant social class effect were evident. 相似文献

Drug-associated cues are critical in reinstating the drug taking behavior even during prolonged abstinence and thus are thought to be a key factor to induce drug craving and to cause relapse. Amygdaloid complex has been known for its physiological function in mediating emotional experience storage and emotional cues-regulated memory retrieval. This study was undertaken to examine the role of basolateral nuclei of amygdala and the intracellular signaling molecule in drug cues-elicited cocaine memory retrieval. Systemic anisomycin treatment prior to the retrieval test abolished the cues-provoked cocaine conditioned place preference (CPP) memory. Likewise, a similar blockade of cues-provoked cocaine CPP performance was achieved by infusion of anisomycin and cycloheximide into the basolateral nuclei of amygdala before the test. Intra-amygdaloid infusion of H89, a protein kinase A inhibitor, or U0126, a MEK inhibitor, did not affect retrieval of the cues-elicited cocaine CPP memory. In contrast, intra-amygdaloid infusion of NPC 15437, a PKC inhibitor, abolished the cues-elicited cocaine CPP expression, while left the memory per se intact. Intra-amygdaloid infusion of NPC 15437 did not seem to affect locomotor activity or exert observable aversive effect. Taken together, our results suggest that activation of PKC signaling pathway and probably downstream de novo protein synthesis in the basolateral nuclei of amygdala is required for the cues-elicited cocaine memory performance. However, temporary inhibition of this signaling pathway does not seem to affect cocaine CPP memory per se. 相似文献

In order to deepen the studies on the philosophy of practice, it is essential to explore the political significance of Marx's
philosophy of practice. Marx's philosophy of practice is rooted in the problem of modernity and the separation between “individual
subjectivity” and “societal community” in the modern context is the basic background of Marx's practical philosophy. It is
the basic interest of Marx's philosophy of practice to find a way to end this separation via critique of civil society. Therefore,
Marx's philosophy of practice has a clear significance, which manifests in the following aspects: one is “liberation politics,”
and the other, “the regulatory mode of the socio-political institution.”

Integral theory is a way of knowing that helps foster the recognition that disparate aspects of reality—such as biological constitution, cultural world‐views, felt‐sense of selfhood, and social systems—are all critically important to any knowledge quest. Integral theory provides an “all quadrants, all levels” (K. Wilber, 2006, p. 26) metatheoretical framework that simultaneously honors the important contributions of a broad spectrum of epistemological outlooks while also acknowledging the parochial limits and misconceptions of those perspectives. In other words, integral theory affords a perspective that allows counselors to situate diverse knowledge approaches in such a way that they synergistically complement, rather than contradict, one another. 相似文献
