Gestational cocaine treatment results in significantly increased maternal aggression towards an intruder by postpartum day six, while acute postpartum treatment dose dependently decreases maternal aggressive (MA) behavior. Both increased and decreased aggression in the cocaine-treated dams are correlated with either decreased or increased levels of oxytocin in the amygdala, respectively. The current study was an effort to determine whether the effect of gestational cocaine on maternal aggression is transient or would continue into the postpartum period; whether an intermittent cocaine treatment regimen, which incorporates gestational and postpartum intermittent cocaine treatment, would differ from chronic daily gestational treatment; and finally, whether next generation female offspring of cocaine-treated or control dams would have altered MA behavior and oxytocin system changes attributable to either prenatal drug exposure, rearing condition or both. We now report no increase in maternal aggression following chronic gestational treatment and significantly lower levels of aggression in intermittently treated dams on postpartum day eight, with no significant effects in either group on postpartum day 12. Young adult female offspring of the cocaine-treated and control dams, who reared their own natural litters and were tested on postpartum day eight for maternal aggression, had higher levels of maternal aggression towards an intruder attributable to both prenatal cocaine exposure and rearing condition. Higher aggression in cocaine-reared next generation dams was associated with lower levels of oxytocin in the amygdala. Intergenerational effects of cocaine were apparent with respect to aggression and oxytocin system changes. 相似文献

The goal of this study was to examine how individual variation in readers’ skills and, in particular, their background knowledge
about a text are related to text memory. Recollection and familiarity estimates were obtained from remember and know judgments
to text ideas. Recollection estimates to old items were predicted by readers’ background knowledge, but not by other comprehension-related
factors, such as word-decoding skill and working memory capacity. False alarms involving recollection of new items (inferences)
were diminished as a function of verbal ability, working memory capacity, and reasoning but increased as a function of background
knowledge. The results suggest that recollection indexes the reader’s ability to construct a text representation in which
text ideas are integrated with relevant domain knowledge. Moreover, these results highlight the importance of background knowledge
in explaining individual variation in comprehension and memory for text. 相似文献

Moses is a great figure of moral and social liberation. His role in the Muslim tradition has been as multifaceted as in Judaism and Christianity. This essay attempts to explore his importance in the ideology of radical Islam by exploring Sayyid Qutb's responses to a number of the Moses scenes of the Qur'an in his work Fi zilal al‐qur'an. Qutb's treatment reveals aspects of the ideological structure that informs his writing, his love of Egypt and his spirituality. It shows, also, how he had a vision of Islam that went far beyond the boundaries of a nation state and regarded Nasser as a betrayer of this vision. He saw the Egyptians suffering under him as they had suffered under Pharoah. 相似文献

Although research has shown that priming negative stereotypes leads to lower performance among stigmatized individuals, little is understood about the cognitive mechanism that accounts for these effects. Three experiments tested the hypothesis that stereotype threat interferes with test performance because it reduces individuals' working memory capacity. Results show that priming self-relevant negative stereotypes reduces women's (Experiment 1) and Latinos' (Experiment 2) working memory capacity. The final study revealed that a reduction in working memory capacity mediates the effect of stereotype threat on women's math performance (Experiment 3). Implications for future research on stereotype threat and working memory are discussed. 相似文献

The pluralizing forces in many English speaking countries include a number of Muslim communities. As these become integrated into their host societies, their social and spiritual values, and above all a recognition of the Qur'an as their sacred Book have the potential to enrich the mythic and symbolic resources of English as a language of literature. For this, the Qur'an needs to establish recognition in the first place at a secular level as literature in order to pave the way for an awareness of its spiritual dimensions. This essay outlines some of the obstacles to such a development, and suggests ways in which they may be overcome. It shows how the Qur'an re‐presents in a distinctive way themes and motifs familiar to English readers of the Bible. It offers English renderings of a number of qur'anic pericopes. It attempts by use of a number of techniques to present them in a way that communicates something of the genius of the Qur'an as literature, and thereby to offer a basis on which non‐Muslims can share with Muslims its distinctive contribution to the spiritual heritage of humankind. 相似文献

We propose that correct rejections are based on information that contradicts the study set, rather than on insufficient familiarity. Using two-dimensional stimuli, we varied the featural overlap between lures and the study set so that one feature of the lure had occurred during study and the second feature of the lure had not occurred. Familiarity varied with the number of times the studied feature had occurred, whereas detectability of the extralist feature varied with the number of studied alternatives on the same dimension. Lures increased in difficulty with familiarity only when familiarity of the studied feature was confounded with the number of alternatives to the extralist feature. Hence, the difficulty in rejecting the lure was controlled by the number of alternatives to the extralist feature, not by the familiarity of the lure. Current theory requires additional representation assumptions and a new comparison process to accommodate these data. 相似文献

At the end of a trial, the judge gives jurors a set of instructions that explain the laws that are applicable to the case and that direct jurors to reach a verdict in accordance with those laws. Little is known about how well jurors understand instructions in civil cases. We assess the extent to which jurors understand judicial instructions in negligence cases. We address 3 issues: (a) To what extent do they understand these instructions? (b) To what extent is their comprehension enhanced by access to a written copy of the instructions? and (c) What effect does deliberation have on jurors' comprehension levels? Overall comprehension was approximately 64% and access to written instructions did not enhance comprehension, but the opportunity to deliberate did. 相似文献
