人际合作与冲突影响博弈决策的结果评价 总被引:1,自引:0,他引:1
人际合作与冲突是人际互动的两种主要形式, 在人类社会的发展中有着重要作用。脑成像研究表明, 当个体和人类同伴进行博弈时, 选择合作与选择冲突激活脑区的强度有所不同。但目前尚不清楚, 人际合作与冲突如何影响决策选择之后的结果评价过程。本研究采用Chicken Game任务对此问题进行了探讨, 研究记录了22名健康成人被试与人类同伴进行Chicken Game任务时的脑电活动。结果表明, 反馈负波(FRN)和P300不仅受到结果效价的影响, 同时也受到人际合作与冲突的影响。相对于选择冲突, 个体选择合作时, 输钱和赢钱反馈引发的FRN以及P300波幅差异更大。相关分析表明, RA (被试和解对方进攻)反馈引发的FRN波幅与接受该反馈后下一个trials中和解的选择率(以及总的和解率)呈显著的负相关。上述结果表明, 在社会博弈中, 合作增加了个体对博弈结果的预期, 从而引发更大的FRN效应; 并且合作共赢的结果所具有的物质意义与社会意义, 使其诱发更大的P300波幅。 相似文献

Optimism bias is a crucial feature of risk perception that leads to increased risk‐taking behaviour, which is a particularly salient issue among pilots in aviation settings due to the high‐stakes nature of flight. The current study sought to address the roles of narcissism and promotion focus on optimism bias in risk perception in aviation context. Participants were 239 male flight cadets from the Civil Aviation Flight University of China who completed the Narcissistic Personality Inventory‐13, the Work Regulatory Focus Scale, and an indirect measure of unrealistic optimism in risk perception, which measured risk perception for the individual and the risk assumed by other individuals performing the same task. Higher narcissism increased the likelihood of underestimating personal risks, an effect that was mediated by high promotion focus motivation, such that high narcissism led to high promotion focus motivation. The findings have important implications for improving the accuracy of risk perception in aviation risks among aviators. 相似文献

The microstructural evolution of nanocrystalline Ni–W alloys with annealing temperature and more specifically grain boundary (GB) character is investigated through several techniques and correlated with the hardening behaviour. It is shown that two distinct regions can be identified in relation to the annealing temperature and the microstructural evolution. At temperatures below 550 °C (Regime I), a small increase in grain size is observed and is accompanied by a significant hardening and an increase in the fraction of Σ3 incoherent twin boundaries. At temperatures above 550 °C (Regime II), the thermal stability is overcome and important grain growth occurs with a decrease in both the volumic fraction of GBs and the microhardness. It is suggested that the microhardness evolution during heat treatment is influenced by two opposing processes: an increase in the fraction of incoherent twin boundaries (hardening effect) and grain growth (softening effect). Both aspects are directly associated with the mean free path of mobile dislocations. 相似文献

To facilitate understanding of the factors associated with child depressive symptoms in middle childhood, we examined the roles of parental support for autonomy and parent–child attachment in child depressive symptoms among 150 Chinese parent–child dyads. The participating children’s ages ranged from 6 to 12 years old. Parental support for autonomy was coded from a conflict resolution and a cooperation task. Children reported their depressive symptoms and their attachment relationships with the participating parents. After controlling for parent depressive symptoms, parental support for autonomy was associated with fewer child depressive symptoms. The association between parental support for autonomy and child depressive symptoms was mediated by parent–child attachment quality, suggesting that parental support for autonomy was negatively associated with child depressive symptoms through its positive association with parent–child attachment quality. Moreover, the positive association between parental support for autonomy and parent–child attachment quality was stronger for older children. The current study expanded the knowledge on parental support for autonomy in middle-childhood and its association with parent–child relationships and child mental health. Future research is encouraged to pay more attention to the role of parental support for autonomy in various aspects of child development for children in middle-childhood and pre-adolescence. 相似文献

To increase game loyalty but decrease game addiction, this study examines online game social migration and tests the mediating effects of offline social value and maladaptive cognition on the basis of the theory of consumption value and the cognitive behavioral model of pathological Internet use. The results are as follows: (i) Overall, online game social migration is associated with greater game loyalty and less game addiction; (ii) The positive association between online game social migration and game loyalty was mediated by offline social value; and (iii) Online game social migration is associated with lower game addiction. This paper provides a new perspective (taking into account both business interests and players' psychological health) for online game research and also offers practical guidance for cooperation between game companies and the public.

Despite its prevalence as one of the most highly influential models of spoken word recognition, the TRACE model has yet to be extended to consider tonal languages such as Mandarin Chinese. A key reason for this is that the model in its current state does not encode lexical tone. In this report, we present a modified version of the jTRACE model in which we borrowed on its existing architecture to code for Mandarin phonemes and tones. Units are coded in a way that is meant to capture the similarity in timing of access to vowel and tone information that has been observed in previous studies of Mandarin spoken word recognition. We validated the model by first simulating a recent experiment that had used the visual world paradigm to investigate how native Mandarin speakers process monosyllabic Mandarin words (Malins & Joanisse, 2010). We then subsequently simulated two psycholinguistic phenomena: (1) differences in the timing of resolution of tonal contrast pairs, and (2) the interaction between syllable frequency and tonal probability. In all cases, the model gave rise to results comparable to those of published data with human subjects, suggesting that it is a viable working model of spoken word recognition in Mandarin. It is our hope that this tool will be of use to practitioners studying the psycholinguistics of Mandarin Chinese and will help inspire similar models for other tonal languages, such as Cantonese and Thai. 相似文献

This study examined correlates of academic procrastination and students’ grade goals in a sample of 226 undergraduates from
Singapore. Findings indicated that self-efficacy for self-regulated learning was significantly and negatively related to procrastination.
High self-efficacy for self-regulated learning also predicted students’ expectations of doing well and low self-efficacy for
self-regulated learning predicted students’ expectations of not doing well academically. Additionally, help-seeking predicted
students’ expectations of doing well academically while academic stress predicted students’ expectations of not doing well
academically. Implications for education and educational practice were discussed.

This study examines the relationship between psychiatric symptoms and violent/disruptive behavior among 192 inmates who participated in prison-based substance abuse treatment. Participants came from two sites able to provide narrative reports of disciplinary actions in the Criminal Justice Drug Abuse Treatment Studies' Co-Occurring Disorders Screening Instrument study. In multivariate logistic models, a lifetime history of thought insertion/control ideation (OR, 11.6; 95% CI, 1.8-75.2), antisocial personality disorder (OR, 3.3; 95% CI, 1.2-8.9), and disciplinary action related to possession of controlled substances or contraband (OR, 4.9; 95% CI, 1.9-12.3) were associated with increased risk for violent or disruptive behavior while in prison, whereas lifetime phobic symptoms (OR, 0.2; 95% CI, 0.1-0.54) and high school graduation (OR, 0.4; 95% CI, 0.2-1.0) were associated with a decreased risk of violence and disruptive behavior in general. We conclude that, among inmates in substance abuse treatment, symptoms that increase risk for violence or disruptive behavior include thought control/insertion ideation and disciplinary infractions related to controlled substances, contraband, or failure to participate in assigned programs, as well a history of antisocial personality disorder. 相似文献

The present study predicts cigarette and alcohol use in adolescence from the development of children's cognitions in the elementary years. Using latent growth modeling, the authors examined a model using data from 712 participants in the Oregon Youth Substance Use Project, who were in the 2nd through 5th grade at the 1st assessment and followed for 6 annual or semiannual assessments over 7 years. Growth in children's prototypes and subjective norms in the elementary years (Times 1 through 4) were related to their substance use in adolescence (Time 6) through their willingness and intentions (Time 5) to smoke and drink. Across the sample, for both substances, the intercept and slope of prototypes were either indirectly related to use through willingness or directly related to use. Both the intercept and slope of subjective norms were indirectly related to use of both substances through both willingness and intentions and directly related to cigarette use. Results suggest that elementary children have measurable cognitions regarding substance use that develop during the elementary years and predict use later in adolescence. These findings emphasize the need for prevention programs targeted at changing children's social images of substance users and encouraging more accurate perceptions of peers' use. 相似文献
