不同反应方式对双作业操作信息干扰的影响 总被引:4,自引:2,他引:2
本研究采用单作业双作业操作,探讨了不同反应方式对双作业操作信息干扰的影响。实验结果证明;若采用相同的反应方式,同时操作的两种作业就会产生相互干扰,降低作业绩效;相反,若采用不同反应方式将减小双作业操作的相互干扰,提高双作业操作绩效。 相似文献

Emotions affects moral judgements, and controlled cognitive processes regulate those emotional responses during moral decision making. However, the neurobiological basis of this interaction is unclear. We used a graph theory measurement called participation coefficient (‘PC’) to quantify the resting-state functional connectivity within and between four meta-analytic groupings (MAGs) associated with emotion generation and regulation, to test whether that measurement predicts individual differences in moral foundations-based values. We found that the PC of one of the MAGs (MAG2) was positively correlated with one of the five recognized moral foundations–the one based on harm avoidance. We also found that increased inter-module connectivity between the ventromedial prefrontal cortex, dorsolateral prefrontal cortex and middle temporal gyrus with other nodes in the four MAGs was likewise associated with higher endorsement of the Harm foundation. These results suggest that individuals' sensitivity to harm is associated with functional integration of large-scale brain networks of emotional regulation. These findings add to our knowledge of how individual variations in our moral values could be reflected by intrinsic brain network organization and deepen our understanding of the relationship between emotion and cognition during evaluations of moral values. 相似文献

从友人处寄来《科技日报》8月6日的上述文章,阅后令人吃惊。多年来全国造船界和航运界公认的“周锦宇超浅水船”伪科学,变成了“开创……船舶运输新纪元”的大发明,一堆堆废铁变成了大成果。这里就该文所涉及的几件事的真相,提供社会各界参考。一、文中说:周锦宇“提出了流体分子量质与物体运动相对瞬变新理论成因这一大胆设想,……是对流体力学研究的重大突破,……其作用是无可估量的”。对于连文句都不通的,没有任何说明的,不知所云的“一句话”理论,怎样突破?何来作用?二、文中说:“30吨级超浅水船畅通闽江上游。”事实是,1987年初福建省… 相似文献

荀子"化性起伪"."隆礼重法"的政治思想是建立在他的性恶的人性论基石上的。以礼为本、德法并举、德主刑辅、礼义教化与法律强制相辅相成,是他政治思想的核心内容,也是其对儒家德治思想的创新发展。剔除其封建糟粕,它对我们今天建设和谐小康社会仍可提供有益的启示。 相似文献

The present study examined the factorial structure of a Chinese language version of the self-report Dimensional Assessment of Personality Pathology Questionnaire in 581 adults. Four factors were extracted (Emotional Dysregulation, Dissocial, Inhibition, and Compulsivity) that are similar to the factors extracted in the scales' normative clinical and general population samples from North America (factor comparability coefficients range from .88 to .96), supporting the idea that this trait structure is invariant across diverse populations. The internal consistency of the scales (Cronbach's alpha) was satisfactory across age and gender groups with the exception of the Intimacy Problems scale. Possible explanations for the poor internal consistency of the Intimacy Problems scale, such as cultural differences in social factors influencing marital and romantic relationships in Chinese populations, as opposed to other populations are discussed. 相似文献

The first objective of this study was to determine whether insulin-induced hypoglycemia (IIH) inhibits LH secretion in unrestrained female macaques during the follicular phase of the menstrual cycle. There was a consistent inhibitory effect of hypoglycemia on LH secretion within 3 h in these females. This inhibition was likely an indirect effect since low glucose levels did not inhibit GnRH secretion from GT1-1 neurones in vitro. We next investigated whether administration of a vasopressin antagonist (AVPa) either alone, or with naloxone could reverse the IIH-induced inhibition of LH release. Females were studied in the follicular phase during 10 h periods with blood samples collected every 10 min. Experimental groups were IIH (n=6), IIH+AVPa (n=5) and IIH+AVPa+naloxone (n=4). The first 5 h of each study served as a control and hypoglycemia was then induced with insulin. The AVPa was given as a bolus (180 microg) just before the insulin and was followed by a continuous infusion (180 microg/h) for 5 h. Naloxone (5 mg/kg) was given with the AVPa and followed by a continuous infusion (5 mg/kg/h) for 5 h. In the IIH group, LH reached its lowest value 3-4 h after insulin. Neither AVPa nor AVPa+naloxone infusion reversed the inhibitory action of hypoglycemia on LH release. These data suggest that if there are inhibitory actions of vasopressin and endogenous opioids on GnRH release induced by hypoglycemia, they are not sufficient to explain the suppression of GnRH/LH release in intact female primates. 相似文献

Previous research has shown that collectivists prefer external whereas individualists prefer internal attributions. To test the findings' generality across social situations, we compared the two attributions in situations where either an individual was acting on a group (Individual-acting) or the reverse (Group-acting). As predicted, collectivists' (Beijing and Hong Kong Chinese) greater preference for externality, and individualists' (Wellington Europeans) greater preference for internality, occurred in individual- but not group-acting situations. Collectivists' (mainly Hong Kong) memory of events was better in group- than in individual-acting situations according to prediction, but the predicted reversal was not found among individualists. The collectivist/individualist categorizations of the samples were supported by measures of self-construal. Indigenous Chinese concepts of 'unity' ( tong tian ren ) and 'combination' ( he nei wai ) were discussed to throw light on attribution processes that are not readily accessible through the concepts of collectivism and individualism. 相似文献
