观点采择对高中教师共情反应的影响:共情倾向的中介作用

为了探讨观点采择与共情倾向对高中教师共情反应的影响,164名高中教师完成了人际反应指数量表,并在三种不同的观点采择指导语下完成共情反应问卷。结果表明:(1)观点采择通过指导语操作检验有效;(2)情感观点采择下的共情反应显著高于认知观点采择下的共情反应;认知观点采择下的共情反应显著高于技术观点采择下的共情反应;(3)情感观点采择通过共情倾向的部分中介作用对共情反应产生影响,认知观点采择通过共情倾向的完全中介作用对共情反应产生影响。     

职业决策情境中信任水平对建议采纳的影响*

研究应用“决策者-建议者系统”(Judge-Advisor System)经典研究范式,以62名大学生为被试,探讨了职业决策情境中信任水平、建议类型对建议采纳的影响。结果发现:(1)决策者的最终决策信心倾向于坚持原有信念;(2)信任水平的主效应及其与建议类型的交互作用对建议采纳主效应存在显著影响;(3)建议者信心对决策者的建议采纳权重具有正向预测作用,并削弱了信任对建议采纳权重的作用。这表明,在职业决策情境中,信任水平对决策者建议采纳权重的影响与建议者提供的建议类型(与决策者的初始决策是否一致),以及提供建议时的信心水平有关。     

Children's note taking as a mnemonic tool

When given the opportunity to take notes in memory tasks, children sometimes make notes that are not useful. The current study examined the role that task constraints might play in the production of nonmnemonic notes. In Experiment 1, children played one easy and one difficult memory game twice, once with the opportunity to make notes and once without that opportunity. More children produced functional notations for the easier task than for the more difficult task, and their notations were beneficial to memory performance. Experiment 2 found that the majority of children who at first made nonmnemonic notations were able to produce functional notations with minimal training, and there was no significant difference in notation quality or memory performance between spontaneous and trained note takers. Experiment 3 revealed that the majority of children could transfer their training to a novel task. The results suggest that children’s production of nonmnemonic notes may be due in part to a lack of knowledge regarding what task information is important to represent or how to represent it in their notes rather than to an inability to make functional notes in general.     

Looking through the eyes of the powerful

Across four experiments, we test the idea that power decreases metastereotyping, and that this effect is mediated by reduced perspective taking. Metastereotypes refer to the beliefs that members of group A share about the stereotypes that members of specific outgroup B typically have about ingroup A. We propose that the dominant psychological orientation of the powerless is aimed at seeing how others see them. In an intergroup situation they are therefore inclined to activate and apply metastereotypes. In the first three experiments we consistently find that low power leads to more metastereotyping than high power and control (in Experiment 3). Specifically, we show this effect with three different manipulations of power, namely a role manipulation (Experiment 1), experiential priming (Experiment 2), and parafoveal priming (Experiment 3). In the fourth experiment we uncover the mediating role of perspective taking. Together these findings provide strong evidence that powerlessness leads to metastereotyping.     

Chimpanzees do not take into account what others can hear in a competitive situation

Chimpanzees (Pan troglodytes) know what others can and cannot see in a competitive situation. Does this reflect a general understanding the perceptions of others? In a study by Hare et al. (2000) pairs of chimpanzees competed over two pieces of food. Subordinate individuals preferred to approach food that was behind a barrier that the dominant could not see, suggesting that chimpanzees can take the visual perspective of others. We extended this paradigm to the auditory modality to investigate whether chimpanzees are sensitive to whether a competitor can hear food rewards being hidden. Results suggested that the chimpanzees did not take what the competitor had heard into account, despite being able to locate the hiding place themselves by the noise.     

娱乐场所服务女性的行为学调查

调查娱乐场所服务女性的性行为特征及其安全套使用情况,为预防性病/艾滋病健康教育和政策制定提供参考信息。采用立意抽样方法对我省南昌和萍乡两地娱乐场所服务女性进行问卷调查。娱乐场所服务女性卖淫比例较高,卖淫者安全套使用比例和频率不高,且卖淫者安全套使用存在不平衡现象。必须进一步加大宣传教育力度及强化干预工作。     

Delay, Probability, and Social Discounting in A Public Goods Game

A human social discount function measures the value to a person of a reward to another person at a given social distance. Just as delay discounting is a hyperbolic function of delay, and probability discounting is a hyperbolic function of odds-against, social discounting is a hyperbolic function of social distance. Experiment 1 obtained individual social, delay, and probability discount functions for a hypothetical $75 reward; participants also indicated how much of an initial $100 endowment they would contribute to a common investment in a public good. Steepness of discounting correlated, across participants, among all three discount dimensions. However, only social and probability discounting were correlated with the public-good contribution; high public-good contributors were more altruistic and also less risk averse than low contributors. Experiment 2 obtained social discount functions with hypothetical $75 rewards and delay discount functions with hypothetical $1,000 rewards, as well as public-good contributions. The results replicated those of Experiment 1; steepness of the two forms of discounting correlated with each other across participants but only social discounting correlated with the public-good contribution. Most participants in Experiment 2 predicted that the average contribution would be lower than their own contribution.     

Neural correlates of Traditional Chinese Medicine induced advantageous risk-taking decision making

This fMRI study examined the neural correlates of the observed improvement in advantageous risk-taking behavior, as measured by the number of adjusted pumps in the Balloon Analogue Risk Task (BART), following a 60-day course of a Traditional Chinese Medicine (TCM) recipe, specifically designed to regulate impulsiveness in order to modulate risk-taking behavior. The 14 participants recruited for this study were randomly assigned to the experimental and control groups and the TCM recipe (Panax, 520 mg; Astragalus membranaceous Bunge, 520 mg; Masnetitum, 840 mg; Ostrea gigas Thumb, 470 mg; Thinleaf Milkwort Root Radix Polygalae, 450 mg; and Os Draconis, 470 mg) was administered, as a diet supplement, to the seven participants in the experimental group. The neural activity of the two groups was monitored by a 3T MRI scanner, before and after the 60-day treatment. Associated with the improved advantageous risk-taking behavior seen in the experimental group, significantly stronger blood oxygenation level dependent (BOLD) responses were observed in the bilateral dorsolateral prefrontal cortex (DLPFC), left putamen, left thalamus, right insula, and right anterior cingulate cortex (ACC), regions which have previously been reported as being involved in risk-taking decision making. The effect of the TCM in improving advantageous risk-taking decision making appears to have been related to the enhanced efficiency of the cognitive affective system, the PFC–ACC–insula–striatum network, which functions to inhibit impulsiveness, to sensitize reward-related information, and to allow the opportunity, during risk estimation, to evaluate potential gains and losses. The findings of this study suggest that interventions acting on factors modulating risk-taking decision making could have a beneficial effect in terms of optimizing risk-taking behavior.
