以往研究考察了不公平经历如何影响个体的认知、情绪及行为。然而, 这些研究着重于考察个体“独自经历”不公平的现象, 而尚未有研究考察, 当个体与他人以群体身份共同经历不公平时, 不公平经历对个体的影响。3项实验采用改编的三人最后通牒博弈任务考察“群体共同经历”不公平如何影响个体的不公平感知。研究结果表明, 无论是通过“共同命运” (实验1)、轮流为群体做决策(实验2), 还是招募成对朋友(实验3)来操纵或凸显群体身份, 群体共同经历不公平, 相比独自经历不公平, 均显著降低(而非提升)了被试的不公平感知。研究结果对于社会及组织管理具有借鉴意义。 相似文献

Do the processing and online manipulation of stimuli that are less familiar require more working memory (WM) resources? Is it more difficult to solve demanding problems when the symbols involved are less rather than more familiar? We explored these questions with a dual-task paradigm in which subjects had to solve algebra problems of different complexities while simultaneously holding novel symbol–digit associations in WM. The symbols were previously unknown Chinese characters, whose familiarity was manipulated by differential training frequency with a visual search task for nine hour-long sessions over 3 weeks. Subsequently, subjects solved equations that required one or two transformations. Before each trial, two different integers were assigned to two different Chinese characters of the same training frequency. Half of the time, those characters were present as variables in the equation and had to be substituted for the corresponding digits. After attempting to solve the equation, subjects had to recognize which two characters were shown immediately before that trial and to recall the integer associated with each. Solution accuracy and response times were better when the problems required one transformation only; variable substitution was not required; or the Chinese characters were high frequency. The effects of stimulus familiarity increased as the WM demands of the equation increased. Character–digit associations were also recalled less well with low-frequency characters. These results provide strong support that WM capacity depends not only on the number of chunks of information one is attempting to process but also on their strength or familiarity. 相似文献

女神崇拜是世界各古老民族共有的一种文化现象.通过对《山海经》《墉城集仙录》《历世真仙体道通鉴后集》等经籍的整理,可初步分离出独立的中华女神谱.在上古神话中,以女娲和西王母为代表的众女神母养群品、教化众生,女神谱系已略具雏形.道教继承了史前女神崇拜,形成了以西王母为尊、墉城为治,以昆仑——上清系为主脉,并融摄民俗女神和历... 相似文献

全球老龄化浪潮正在来临,亲社会行为倾向的年龄差异受到广泛关注。基于第六次世界价值观调查数据集,运用39887个全球成年样本对全球人口亲社会行为倾向的年龄差异进行检验,并探究年龄通过共情关怀和人际信任影响亲社会行为的中介机制。结果表明:全球范围内,年龄显著正向影响亲社会行为倾向,共情关怀不存在显著的年龄差异,人际信任在年龄和亲社会行为倾向之间起显著的中介效应。研究结果对考察亲社会行为倾向的年龄差异及其作用机制具有重要理论价值和实践意义。 相似文献

Individuals’ goal-directed activity in one situation can affect their behavior in a later, ostensibly unrelated situation. This effect can depend on whether the latter behavior is also goal-directed or is performed automatically. Three studies showed that participants’ rate of speaking in the course of performing a speech shadowing task has a positive influence on the speed with which they later complete an ostensibly unrelated marketing survey. Furthermore, when participants’ attention is called to the goal of working rapidly on the survey, the effect of their past behavior depends on their perception of the goal's desirability. When the time to complete the survey is not mentioned, however, participants’ speed of working on the survey is influenced by their speed of speaking in the earlier situation without their awareness and it does not depend on the desirability of the goal with which their behavior is associated. An additional experiment showed that the relative impact of goal-directed and automatic processes also depends on the cognitive resources that people have available to construe the evaluative implications of their decisions. 相似文献

Evidence suggests that the nitric oxide (NO)/soluble guanylyl cyclase (sGC)/cGMP dependent protein kinase (PKG) signaling pathway plays a key role in memory processing, but the actual participation of this signaling cascade in the hippocampal CA1 during morphine-induced reward memory remains unknown. In this study, we investigated the role of the NO/sGC/PKG signaling pathway in the CA1 on morphine-induced reward memory using a conditioned place preference (CPP) paradigm. We found that rats receiving an intraperitoneal (i.p.) injection of 4mg/kg morphine exhibited CPP, whereas rats treated with only 0.2mg/kg morphine failed to produce CPP. Intra-CA1 injection of the neuronal NO synthase (nNOS) inhibitor 7-NI, the sGC inhibitor ODQ or the PKG inhibitor Rp-8-Br-PET-cGMPS had no effect on the acquisition of CPP by 4mg/kg morphine. Intra-CA1 injection of 7-NI blocked the consolidation of CPP induced by 4mg/kg morphine, and this amnesic effect of 7-NI was mimicked by ODQ and Rp-8-Br-PET-cGMPS. Intra-CA1 injection of the NOS substrate L-arg or the sGC activator YC-1 with an ineffective dose of morphine (0.2mg/kg, i.p.) elicited CPP. This response induced by L-arg or YC-1 was reversed by pre-microinjection of Rp-8-Br-PET-cGMPS in the CA1. These results indicated that the activation of the NO/sGC/PKG signaling pathway in the CA1 is necessary for the consolidation of morphine-related reward memory. 相似文献

为了考察背景性质对ASD者搜索面孔的影响,设计两个眼动实验任务,要求14名7~10岁ASD儿童和20名同年龄正常儿童观看图片。实验一采用将面孔嵌入风景图片中引起语义不一致的刺激;实验二采用含有面孔的无意义背景乱序图片刺激。结果发现:(1)面孔与背景语义不一致并不能促进ASD儿童对面孔的搜索;(2)乱序背景对ASD儿童面孔搜索与加工没有产生干扰作用,但使正常儿童的搜索时间变长;(3)一旦觉察到面孔后,ASD儿童对面孔的注视时间少于正常儿童。表明正常儿童对面孔的搜索与加工受背景性质的影响,而ASD儿童不受背景性质的影响;一旦发现面孔,ASD儿童的注意维持较短,但面孔加工模式与正常儿童相似。 相似文献
