Our stage in life has profound influences on our emotions. A well-established age-related positivity effect is putatively related to time perspectives—older adults have a limited time perspective and a greater motivation to experience positivity than young adults. Ambiguous emotions (e.g., surprised expressions) have both a positive and negative meaning, offering a highly relevant model for examining this developmental trend. Indeed, there are stable, trait-like individual differences in valence bias, or the tendency to interpret surprise as positive or negative, with a developmental trend toward positivity (older adults are more positive than young adults, who are more positive than children). However, little research has determined the extent to which the bias can be shifted. In three experiments, we found that ambiguity ratings were sensitive to time perspectives, even within a population of college students, and that this effect is relatively long-lasting. Results extend socioemotional selectivity theory and demonstrate that our life stage may have profound effects on otherwise stable emotional responses.  相似文献

Soluble oligomeric forms of amyloid beta (AβO) are regarded as a main cause of synaptic and cognitive dysfunction in Alzheimer’s disease (AD) and have been a primary target in the development of drug treatments for AD. The present study utilized a mouse model of AD induced by intrahippocampal injection of AβO (10 μM) to investigate the effects of Gami-Chunghyuldan (GCD), a standardized multi-herbal medicinal formula, on the presentation of memory deficits and neurohistological pathogenesis. GCD (10 and 50 mg/kg/day, 5 days, p.o.) improved AβO-induced memory impairment as well as reduced neuronal cell death, astrogliosis, and microgliosis in the hippocampus. In addition, GCD prevented AβO-triggered synaptic disruption and cholinergic fiber loss. These results suggest that GCD may be useful in the prevention and treatment of AD.  相似文献

Alcohol, tobacco and other drug abuse continue to cause major threats to the physiological, psychological, sociological and spiritual health of the nation. According to recent statistics, over 80% of the illegal drugs used by youth, both male and female, is marijuana, with cocaine, opium and their derivatives comprising at least 15% of the drugs used by youth. When considering the ill effects of drug abuse, it is the legal one, alcohol that is responsible for the greatest impact on society. While it remains imperative that allied health professionals understand the many ramifications of substance abuse, it is also critical that leaders of faith communities have the knowledge and skills to meet this challenge competently. Due to the relevance of ministries as a possible resource, the focus of this exploratory study is to assess the knowledge, skills and attitudes of clergy about substance use and abuse and to determine their confidence of clergy in assisting their congregation with need related to this area.  相似文献

Prior work suggests that nonface objects of expertise can interfere with the perception of faces when the two categories are alternately presented, suggesting competition for shared perceptual resources. Here, we ask whether task-irrelevant distractors from a category of expertise compete when faces are presented in a standard visual search task. Participants searched for a target (face or sofa) in an array containing both relevant and irrelevant distractors. The number of distractors from the target category (face or sofa) remained constant, whereas the number of distractors from the irrelevant category (cars) varied. Search slopes, calculated as a function of the number of irrelevant cars, were correlated with car expertise. The effect was not due to car distractors grabbing attention, because they did not compete with sofa targets. Objects of expertise interfere with face perception even when they are task irrelevant, visually distinct, and separated in space from faces.  相似文献

在3个月的时间内对425名大学新生进行3次追踪测量,以考察时间管理倾向、手机依赖与无聊倾向之间的因果顺序和发展变化趋势。结果发现:(1)大学新生的无聊倾向与时间管理倾向呈同时性和继时性的负相关,并与手机依赖水平呈同时性和继时性的正相关。(2)T1和T2的无聊倾向分别正向预测T2和T3的手机依赖,并分别负向预测T2和T3的时间管理倾向;T1的时间管理倾向负向预测T2的无聊倾向;T2的手机依赖正向预测T3的无聊倾向。结论:无聊倾向分别与手机依赖、时间管理倾向之间存在相互预测关系。  相似文献

According to appraisal theorists, anger involves a negative event, usually blocking a goal, caused by another person. Critics argue that other-agency is unnecessary, since people can be angry at themselves, and thus that appraisal theory is wrong about anger. In two studies, we compared anger, self-anger, shame, and guilt, and found that self-anger shared some appraisals, action tendencies, and associated emotions with anger, others with shame and guilt. Self-anger was not simply anger with a different agency appraisal. Anger, shame, and guilt almost always involved other people, but almost half of the occurrences of self-anger were solitary. We discuss the incompatibility of appraisal theories with any strict categorical view of emotions, and the inadequacy of emotion words to capture emotional experience.  相似文献

In this study we examined self-reported suicide attempts and their relationship to other health risk factors in a community sample of 16,644 adolescents. Fifteen percent endorsed suicide attempts (10% single; 5% multiple attempts) We hypothesized that multiple attempters would show higher prevalence of comorbid health risks than single or non-attempters. The three groups showed significant differences in ten health risk domains, on factors such as depressed mood, sexual assault, weight problems, and drug and alcohol use (ORs: 3.26-13.57). Repeated suicide attempts appear to be related to increased vulnerability and likelihood of harm in multiple domains of health risk.  相似文献

"三资"企业劳资关系研究   总被引:8,自引:0,他引:8

改革开放以来,"三资"企业不断增长,为中国经济迅速增长做出了重要贡猷的同时,也引发了一些社会问题,主要反映在劳动者劳权的实现状况和劳资关系冲突方面.通过对三个外资企业的个案研究说明,外资企业存在着三种劳资关系模式,即冲突型劳资关系模式、谈判-契约型劳资关系模式和利益一致型的以人力资源管理为主的劳资关系模式.企业类型、投资方式、企业规模、生产要素的配置、企业文化传统以及在地政府的行为等多种因素影响外资企业劳资关系模式.  相似文献

通过操纵目标刺激的表面形式变化,在内隐和外显记忆任务之间,发现了实验性分离现象,图形识别任务受到了这种操纵的影响,再认任务则没有,同时发现,它们存在着依赖性的关系。对比相关研究,该实验结果表明,概念驱支任务对刺激的表面或知觉的物理性表现出敏感性,是在刺激的编码阶段;数据驱动任务在码阶段和提取阶段,均对其表现出敏感性,在刺激的提取阶段,这两种类型任务提取了刺激的某些共同成分。  相似文献
