多义词造句任务对负性解释偏差的测量

本研究旨在归纳中文里可以用于测量解释偏差的多义词,并使用多义词造句任务,在广泛性焦虑症状人群中评估其测量有效性。经过对多义词负性与非负性含义常用程度的评分以及多义词造句任务项目区分度、信度、效度和目的隐蔽性的检验,筛选出两含义常用程度大致相同且对焦虑较为敏感的34个题目构成多义词造句任务,该任务信度良好,可以有效测得高低广泛性焦虑和状态焦虑人群中解释偏差的显著差异,且与同类的乱句重排任务相比,能猜出与猜对实验目的的被试显著更少。因此,中文多义词造句任务信效度良好,具有便捷、隐蔽的优势,可以用于解释偏差的相关研究。     

Categorisation salience and ingroup bias: The buffering role of a multicultural ideology

The current work sought to test the moderating role of a multicultural ideology on the relationship between categorisation salience and ingroup bias. Accordingly, in one experimental study, we manipulated categorisation salience and the accessibility of a multicultural ideology, and measured intergroup attitudes. Results show that categorisation salience only leads to ingroup bias when a multiculturalism (MC) ideology is not made salient. Thus, MC ideology attenuates the negative effects of categorisation salience on ingroup bias. These results pertain to social psychology in general showing that the cognitive processes should be construed within the framework of ideological contexts.     

Individual Differences in Susceptibility to Misinformation Effects and Hindsight Bias

The present study examined individual differences in susceptibility to two similar forms of memory distortion: the misinformation effect and hindsight bias. The misinformation effect occurs when individuals witness an event, are provided with misinformation, and recall the original event as containing elements of the misinformation. Hindsight bias occurs when individuals make judgments, are provided with feedback, and recall their original judgments as being more similar to the feedback than they actually were. Seventy-five participants completed a misinformation task, a hindsight bias task, and several individual difference measures related to memory distortions. Working memory capacity was negatively correlated with the misinformation effect and hindsight bias, and the misinformation effect and hindsight bias were negatively correlated with one another. Although the misinformation effect and hindsight bias are measured with similar designs, and both are predicted by working memory capacity, the negative correlation between them suggests these phenomena result from somewhat different processes.     

Religious Bias Among Religiously Conscious Black Christians in the United States

Research with White participants has demonstrated religious intergroup bias; however, religious identity may be different for Black Americans. Only religiously conscious Black Christians demonstrated a preference for Christian targets over Muslim and Atheist targets. Future research should consider what factors result in a person becoming conscious of other's religion.     

Anxiety and speaking in people who stutter: An investigation using the emotional Stroop task

People with anxiety disorders show an attentional bias towards threat or negative emotion words. This exploratory study examined whether people who stutter (PWS), who can be anxious when speaking, show similar bias and whether reactions to threat words also influence speech motor planning and execution. Comparisons were made between 31 PWS and 31 fluent controls in a modified emotional Stroop task where, depending on a visual cue, participants named the colour of threat and neutral words at either a normal or fast articulation rate. In a manual version of the same task participants pressed the corresponding colour button with either a long or short duration. PWS but not controls were slower to respond to threat words than neutral words, however, this emotionality effect was only evident for verbal responding. Emotionality did not interact with speech rate, but the size of the emotionality effect among PWS did correlate with frequency of stuttering. Results suggest PWS show an attentional bias to threat words similar to that found in people with anxiety disorder. In addition, this bias appears to be contingent on engaging the speech production system as a response modality. No evidence was found to indicate that emotional reactivity during the Stroop task constrains or destabilises, perhaps via arousal mechanisms, speech motor adjustment or execution for PWS.Educational objectives: The reader will be able to: (1) explain the importance of cognitive aspects of anxiety, such as attentional biases, in the possible cause and/or maintenance of anxiety in people who stutter, (2) explain how the emotional Stroop task can be used as a measure of attentional bias to threat information, and (3) evaluate the findings with respect to the relationship between attentional bias to threat information and speech production in people who stutter.     

Malleability of weight-biased attitudes and beliefs: A meta-analysis of weight bias reduction interventions

Weight bias exists across many important life domains, necessitating interventions designed to reduce weight-biased attitudes and beliefs. Though the effectiveness of weight bias interventions has been questioned, to our knowledge no meta-analysis of these interventions has been conducted. This meta-analysis evaluated the impact of weight bias interventions on weight-biased attitudes and beliefs and explored potential moderators. Interventions were eligible if they used an adult sample and a validated measure of weight-biased attitudes, which resulted in the inclusion of 30 studies represented in 29 articles. A random effects approach using inverse weights resulted in a mean effect size estimate of g = −0.33 (lower scores indicate less weight bias) for both attitudes and beliefs. Intervention type, publication type, and population type were not significant moderators but demonstrated noteworthy trends. Results reveal a small, positive effect of weight bias interventions on weight-biased attitudes and beliefs and provide useful information for future interventions.     

Relevance drives attention: Attentional bias for gain- and loss-related stimuli is driven by delayed disengagement

Attentional bias to gain- and loss-related stimuli was investigated in a dot-probe task. We used coloured stimuli that had acquired their valence during the experiment by signalling the chance to either win or lose points in a game task. Replicating previous findings with the additional singleton paradigm, we found attentional bias effects for both gain- and loss-related colours. The effects were due to delayed disengagement from valent stimuli, especially if they were positive, and could not be explained by nonattentional processes like behavioural freezing. Our findings suggest that stimuli signalling opportunities and dangers hold attention, supporting a general motivational relevance principle of the orienting of attention.     

Who knows what's good to eat? Infants fail to match the food preferences of antisocial others

Humans gather most of their knowledge about the world, including objectively true facts and specific cultural norms, by observing and being taught by others. Some individuals are worthy teachers and objects of imitation, having knowledge of cultural practices and positive intentions to inform. Others are better ignored because they are ignorant, because they mean us harm, or simply because we do not wish to be “like them.” This study examines whether 16-month-olds are sensitive to the pro- or antisocial behavior of a source that demonstrates preference for two novel foods. Infants took the emotional reactions displayed by novel and previously prosocial sources, but not antisocial sources, into account when deciding what to eat. These results suggest that others’ social behavior influences infants’ likelihood to match their preferences, illustrating the influence of social evaluation on social learning.     

抑郁个体对情绪面孔的返回抑制能力不足

探讨抑郁对情绪面孔返回抑制能力的影响。以贝克抑郁量表、自评抑郁量表、CCMD-3和汉密顿抑郁量表为工具筛选出了正常对照组、抑郁康复组和抑郁患者组各17名被试进行了真人情绪面孔线索-靶子任务的行为学实验和事件相关电位(ERP)实验。在线索靶子范式中, 靶子在线索消失后出现, 被试对靶子的位置作出反应。行为学实验显示线索靶子间隔时间(stimulus onset asynchronies, SOA)为14ms时, 正常对照组对中性面孔有返回抑制效应, 抑郁康复组对所有面孔均存在返回抑制效应, 患者组对愤怒、悲伤面孔和中性面孔存在返回抑制效应; SOA为250ms时三组被试均对悲伤面孔存在返回抑制能力不足, 以患者组最突出, 康复组对高兴面孔存在返回抑制能力不足; SOA为750ms时正常组对悲伤面孔存在返回抑制效应, 康复组对高兴和悲伤面孔存在返回抑制能力不足, 患者组对悲伤面孔存在返回抑制能力不足, 对愤怒面孔存在返回抑制效应。在SOA为750ms的条件下, ERP波形特点为正常组对高兴面孔线索P3波幅大于其他组, 对高兴面孔无效提示P1波幅小于其他面孔, 对悲伤面孔有效提示P1波幅小于高兴面孔, 对高兴面孔有效提示P3波幅大于患者组, 对悲伤面孔无效提示P3波幅大于其他组; 康复组对悲伤面孔线索P3波幅大于其他面孔, 对高兴面孔有效提示P3波幅大于患者组, 对悲伤面孔无效提示P3波幅小于正常组; 患者组对悲伤面孔线索P1波幅大于其他组、P3波幅大于其他面孔, 对悲伤面孔无效提示P3波幅小于正常组, 高兴面孔有效提示P3波幅小于其他组。提示抑郁患者对负性刺激有返回抑制能力不足, 这种对负性刺激抑制能力的缺失导致抑郁个体难以抗拒负性事件的干扰而受到不良情绪状态的困扰, 所以他们可能更多的体验到抑郁情绪, 并致使抑郁持续和发展。而抑郁康复个体对高兴、悲伤面孔均有返回抑制能力不足, 这让康复个体能同时感受到正、负性刺激, 从而能保持一种认知和情绪上特定的平衡。
