本文分别以90名和70名大学生为被试,通过问卷调查和实验任务的方式,探究童年环境、当前环境压力、时间感知和跨期选择四者之间的关系。结果表明:(1)童年环境影响时间感知,相比童年社会经济地位高的个体,童年社会经济地位低的个体更倾向于高估时距。(2)在正常环境下,个体时间感知完全中介作用于童年环境和跨期选择之间的关系,童年环境通过影响个体时间感知进而影响个体的跨期选择。(3)在当前环境压力下,时间感知并未起到中介作用。研究表明,时间感知在童年压力与在当前环境压力条件下,对跨期选择的影响作用不同。  相似文献

Throughout life new neurons are generated in dentate gyrus of hippocampus. Previous studies have found that spatial tasks can rescue newly born neurons from death. However, it is still unknown whether new neurons are similarly affected by all types of hippocampal-dependent tasks. Here we investigated the possible effects of working memory task (WMT) on immature neurons. Mice were trained in reference memory task and WMT respectively. The reference memory task used the classical hidden platform (HP) water maze task, while WMT used a delayed matching-to-place (DMTP) water maze task. Bromodeoxyuridine (BrdU) was administrated during the early or late phase of training, or 1week prior to training, in order to label dividing proliferating cells. After water maze training, the number of BrdU-labeled cells in dentate gyrus of hippocampus was compared. In addition, hippocampal brain-derived neurotrophic factor (BDNF) and Notch 1 receptor were characterized using Western blot. Serum corticosterone levels were also measured using enzyme immunoassay. Results showed that HP task and DMTP task did not change the number of BrdU-labeled cells produced during the early or late phase of training. As expected, the HP task increased the number of BrdU-labeled cells produced 1 week prior to training. However, DMTP task decreased the number of BrdU-labeled cells produced 1 week prior to training. Both tasks lead to a significant increase in serum corticosterone levels and did not change the expression of BDNF and Notch 1 receptor in hippocampus. Taken together, these results demonstrate that WMT has different effects on survival of immature neurons, and therefore suggests immature neurons may have more than one role depending on the demands of the tasks.  相似文献

马克思关于生产方式决定分配方式的历史唯物主义观点是认知和建构分配公正的逻辑前提。在共产主义社会第一阶段,要以创造价值的劳动为基本尺度实行分配,即按劳分配,虽然以劳动为尺度对社会总产品进行分配的原则超越了"按资分配",但按劳分配也是特殊公正论,仍然是形式公正,是初步的、非完全意义上的实质公正。分配的实质公正——按需分配,只有在共产主义社会高级阶段才能实现。  相似文献

太极拳以其四两拨千斤的技击理念和深厚的哲学内涵闻名于中外。太极拳源于何处?金庸先生的小说《倚天屠龙记》和电影《太极张三丰》都把张三丰算作太极拳的创始人,而把湖北省十堰市的武当山算作太极拳的发祥地。到底是不是这样呢?太极拳究竟是来源于一个人,还是来源于一种中华民族的文化精神?带着疑问,笔者走进武当,一探究竟。  相似文献

Although P3 event-related potential abnormalities have been found in psychopathic individuals, it is unknown whether successful (uncaught) psychopaths and unsuccessful (caught) psychopaths show similar deficits. In this study, P3 amplitude and latency were assessed from a community sample of 121 male adults using an auditory three-stimulus oddball task. Psychopathy was assessed using the Psychopathy Checklist-Revised (Hare, 2003) while childhood physical maltreatment was assessed using the Conflict Tactic Scale (Straus, 1979). Results revealed that compared to normal controls, unsuccessful psychopaths showed reduced parietal P3 amplitudes to target stimuli and reported experienced more physical abuse in childhood. In contrast, successful psychopaths exhibited larger parietal P3 amplitude and shorter frontal P3 latency to irrelevant nontarget stimuli than unsuccessful psychopaths. This is the first report of electrophysiological processing differences between successful and unsuccessful psychopaths, possibly indicating neurocognitive and psychosocial distinctions between these two subtypes of psychopathy.  相似文献

目的:了解高中生的绝望感、自杀意念状况,分析中学生自杀意念的保护性因素的作用机制,为自杀的心理干预提供必要的支持。方法:采用分层整群抽样法抽取在校高中生300人,利用应对效能量表、贝克绝望量表和自杀意念量表等进行调查分析。结果:自杀意念者的检出率为15%,数量分布无性别、年级和独生子女上的差异;应对效能、家庭亲密度和适应性和乐观主义与自杀意念呈显著负相关,对自杀意念有显著的负向影响;乐观主义在应对效能、家庭亲密度和适应性对自杀意念的影响种起部分中介作用。结论:应对效能、家庭亲密度和适应性和乐观主义是自杀意念的重要保护性因素;应对效能、家庭亲密度和适应性通过乐观主义对自杀意念产生影响。  相似文献

The present study was designed to examine the mediating effect of self-efficacy on relations of middle school students' four achievement goals with their perceptions of two motivational climates and in-class physical activity in physical education. The four achievement goals (mastery-approach, mastery-avoidance, performance-approach, and performance-avoidance), perceptions of the motivational climate (mastery- and performance-involving climates), and self-efficacy were measured in a sample of 194 students (93 boys, 101 girls) in a public school. Students' in-class physical activity was assessed using Actical Accelerometers. A series of multiple-regression analyses supported the mediating effect of self-efficacy on the relationships among students' mastery-approach goal, perceived mastery-involving climate, and physical activity.  相似文献

The present research explores whether the type of relationship one holds with deceptive or honest actors influences cross-cultural differences in reward and punishment. Research suggests that Americans reward honest actors more than they punish deceptive perpetrators, whereas East Asians reward and punish equally (Wang & Leung, 2010). Our research suggests that the type of relationship with the actor matters for East Asians, but not for Americans. East Asians exhibit favoritism toward their friends by rewarding more than punishing them, but reward and punish equally when the actors are strangers (Experiment 1 and 2); Americans reward more than they punish regardless of the type of relationship (Experiment 2). Furthermore, the findings were replicated when the proposed mechanism – social mobility – was manipulated within the same culture (Experiment 3). We discuss the implications of these findings for understanding how friends versus strangers are rewarded and punished in an increasingly relationally complex world.  相似文献

The authors propose a new procedure for reducing faking on personality tests within selection contexts. This computer-based procedure attempts to identify and warn potential fakers early on during the testing process and then give them a chance for recourse. Two field studies were conducted to test the efficacy of the proposed procedure. Study 1 participants were 157 applicants competing for 10 staff positions at a large university located in a southern city in the People's Republic of China. In Study 1, potential fakers received a warning message, whereas nonfakers received a nonwarning (control) message. Study 2 participants were 386 Chinese college students applying for membership of a popular student organization at the same university where Study 1 was conducted. In Study 2, the warning and control messages were randomly assigned to all applicants. Results showed some promise for the proposed procedure, but several practical issues need to be considered.  相似文献
