越“八卦”越沉迷:人际好奇与大学生社交网站成瘾倾向的关系

本研究基于“使用与满足”理论和有限自制力理论,探讨人际好奇与大学生社交网站成瘾倾向的关系,并在此基础上建构了一个有调节的中介模型,考察错失恐惧的中介作用和特质自我控制的调节作用。采用方便抽样法对湖北省和河南省各一所综合性大学621名使用微信朋友圈或QQ空间的学生进行问卷调查,结果显示：（1）人际好奇与错失恐惧、社交网站成瘾倾向显著正相关,与特质自我控制显著负相关;错失恐惧与特质自我控制显著负相关,与社交网站成瘾倾向显著正相关;特质自我控制与社交网站成瘾倾向显著负相关;（2）错失恐惧在人际好奇与大学生社交网站成瘾倾向之间起中介作用,特质自我控制调节该中介路径的后半段。具体而言,相对于高特质自我控制的大学生,间接效应对于低特质自我控制的大学生更加显著。本研究结果揭示了人际好奇对大学生社交网站成瘾倾向的影响及其作用机制,对大学生社交网站成瘾的干预具有一定的指导意义。     

Moderator Role of Looming Cognitive Style (LCS) in the Relationship Between Attentional Control and Anxiety: Difference Between Shifting and Focusing Dimensions

Attentional control (AC) that is composed of shifting and focusing dimensions had been suggested as a transdiagnostic risk factor, associated with development and maintenance of various psychological disorders. In comparison, Looming Cognitive Style (LCS) had been documented as a trait-based, disorders-specific characteristic that is linked to high levels of subjectively felt anxiety. The present study investigated whether individual differences in LCS moderated the association of shifting and focusing with anxiety. Participants were 402 individuals between ages 18 and 68 recruited through advertisements posted on various forums, e-mail groups, and social media websites. They filled out questionnaires assessing AC, LCS, anxiety, and depression online. Results of the moderation analyses indicated that at high levels of LCS, low attentional shifting ability was associated with more intense anxiety. A similar relationship with LCS was not observed for focusing. In conclusion, for individuals who have high LCS and low shifting ability, content of and distress coming from looming images is experienced in a more intense manner due to difficulty in shifting to another (perhaps less anxiety provoking) content more flexibly. The findings are providing support for the interactive–synergistic perspective, indicating that deficits in shifting capacity may potentiate negative impact of looming cognitions.     

论现代临床医学发展的人文走向

我们不能用静止的眼光看待当代的医学。在整个“以人为本”的环境背景和其它因素的影响下,近二十多年以来,现代医学正在开始走出人性冷漠的阴影,出现了一些重要的人文走向,尽管这还只是开始,但无疑给人们以希望和信心。     

Contextual effects on prejudiced attitudes: When the presence of others leads to more egalitarian responses

In the present paper, we tested the hypothesis that the physical presence of other ingroup members may ameliorate Whites’ spontaneous affective responses toward Blacks. Results of Study 1 demonstrated that IAT-assessed attitudes toward Blacks were indeed less negative when participants were tested in small groups rather than individually. Study 2 shed light on the underlying processes by demonstrating that respondents at the presence of others displayed increased accessibility to egalitarian-related concepts after Black primes, as compared to respondents tested individually. Overall, results point to the wide malleability of spontaneous affective responses and to the possibility that contextual factors, like the presence of other individuals, might automatically activate egalitarians goals. Results are discussed in relation to current models of automatic intergroup bias and preconscious control over it.     

Seeing is not enough: manipulating choice options causes focusing and preference change in multiattribute risky decision‐making

We show that preferences depend on the attributes that can be directly manipulated when people need to integrate multiple sources of information because direct manipulation causes focusing bias. This effect appears even when all relevant information is simultaneously and explicitly presented at the time the decisions are made. Participants decided how much to save, what investment risk to take and observed the future financial consequences in terms of the mean and variability of the expected retirement income. Participants who manipulated only the future income distribution saved more and took less risk. This effect disappears when the risk‐related variables are removed, which indicates that task complexity is a mediator of such focusing effects. A more balanced trade‐off between the choice attributes was selected when all attributes were manipulated. However, when there is a dichotomy between manipulating versus observing choice attributes, then decisions were based mostly on the manipulated attributes.

面部表情的跨文化表达与识别研究述评

近年来面部表情的跨文化研究显示出更多的跨文化一致性和差异性证据。自发面部表情的表达和识别、组内优势效应以及面部表情信息的上下不对称性已成为该领域的研究热点。方言理论、中国民间模型和EMPATH模型从三种不同的角度对面部表情跨文化研究的结果进行了理论解释。而表达规则和解码规则以及语言效应是面部表情跨文化表达与识别的重要影响因素。今后, 面部表情跨文化的表达和识别研究应更加关注面部表情特征信息和影响因素这两个方面。     

Spontaneous rotation of nanoparticles in a medium

In many experiments, the effects of spontaneous rotation of nanoparticles in a medium have been observed. In the article it has been shown that the reason for the spontaneous rotation of nanoparticles in a medium may be due to an increase in rotational entropy that accompanies the increasing rotational frequencies of the nanoparticles. An equation describing the rotational motion of the nanoparticles in a medium is obtained and its solution is found. It is shown that the formation of a large number of randomly oriented nanocrystals may be a reason for the forming of an amorphous phase upon cooling a melt.     

Why are negative behaviours likely to be immediately invoked traits? The effects of valence and frequency on spontaneous trait inferences

People make trait inferences immediately when observing others’ behaviours. Previous studies reported that this spontaneous trait inference (STI) occurs more strongly from negative behaviours than from positive behaviours. However, what is responsible for this negativity bias in STI is unclear. In this study, two experiments investigated the effects of valence (an event's affective positivity or negativity) and frequency (how frequently the behaviour is observed in everyday life) on the occurrence of STI using an adapted version of a savings‐in‐relearning paradigm. Experiment 1 revealed that only valence affected the frequent occurrence of STI. In addition, the instructions to suppress impression formation or to focus attention on an actor's face made no difference to the results. In Experiment 2, the negativity bias in STIs was shown a week after exposure to the behavioural stimuli. These results suggest that the negativity bias in STIs occurs robustly, and the negative valence of observed behaviour is mostly responsible for the negativity bias in STI. The importance of immediate categorization of negative stimuli is discussed in terms of ecological priority.     

Causal and moral responsibility: Antecedents and consequences of group‐based guilt

In six studies (N = 1045) conducted in three European countries, we demonstrate distinctions between causal responsibility, group‐based guilt, and moral responsibility. We propose that causal responsibility is an antecedent of group‐based guilt linking the ingroup to previous transgressions against the victim group. In contrast, moral responsibility is a consequence of group‐based guilt and is conceptualized as a sociomoral norm to respond to the consequences of the ingroup's transgressions and the current needs of the victim group. As such, moral responsibility can be stimulated by group‐based guilt and directly predicts individual action intentions. Studies 1 and 2 focus on the conceptual distinctions among the three constructs. Study 3 tests the indirect effect of causal responsibility on moral responsibility via group‐based guilt. The remaining studies explore the mediating role of moral responsibility in associations between group‐based guilt and compensatory action tendencies, that is, financial compensation (study 4), approach and avoidance tendencies (study 5) and public apology (study 6). Together these studies show that causal and moral responsibility are psychologically distinct concepts from group‐based guilt and that moral responsibility plays an important role in shaping the effects of group‐based guilt on behavioral intentions.

Isolation effects and the neglect of indirect effects of fiscal policies

People tend to focus on salient cues, ignoring others. We demonstrate such isolation effects in situations involving taxes and public finance, through experiments conducted on the World Wide Web. In general, subjects minimized or ignored the longer‐term or indirect effects of tax policies, such as price increases from business taxes. Subjects preferred “hidden” taxes to transparent ones, failing to think through who would ultimately pay. The preference for hidden taxes was greater when it was uncertain who would pay. When subjects were prompted to think about indirect effects, their preference for hidden taxes was reduced but not eliminated. These observations are symptoms of general tendencies not to think ahead about the effects of public policies. Copyright © 2006 John Wiley & Sons, Ltd.
