厌恶情绪加工特点的事件相关电位研究

厌恶作为一种威胁相关情绪有着帮助人们躲避有害刺激的进化意义。近年来的研究表明, 厌恶加工能拥有独特的神经机制, 主要表现为在感觉刺激输入早期起抑制作用。本研究使用高时间分辨率的事件相关电位技术(event-related potential, ERP)作为研究手段, 探究正常被试观看厌恶图片时脑电活动变化。采用视觉搜索范式作为实验任务, 考察不同加工阶段注意资源消耗特点。脑电结果表明, 厌恶加工确实存在独特的加工机制, 表现为皮层活动先抑制后增强。行为结果呈显著交互作用：情绪图呈现时间较短时(0/300 ms), 被试任务表现受负性情绪加工干扰; 情绪图呈现时间较长时(600/900 ms), 被试任务表现不受负性情绪干扰。研究结果支持负性情绪两阶段加工模型, 即厌恶加工也存在先自动化后控制化的两个阶段, 并且在自动化加工完全消失之前存在两种加工进程并存的过度阶段。     

群体认同在集群行为中的作用机制

在集群行为背景下, 群体认同对个体的集群行为意愿既具有直接的动员作用, 同时也可以调节群体情绪和群体效能变量与人们行为意愿间的关系。政治认同、共同认同与双重认同等特殊形式的群体认同对集群行为的发生具有不同的影响。从动态性研究的角度看, 参与集群行为会强化个体对内群体的认同感, 而强烈的群体认同则会对参与者的行动产生持续影响。今后的研究应根据集群行为的不同触发情境、不同形式及不同发展阶段对群体认同的复杂工作机制进行探讨。     

Disgust as embodied loss aversion

A quickly expanding literature has examined the link between physical disgust and morality. This article critically integrates the existing evidence and draws the following conclusions: First, there is considerable evidence that experimentally induced disgust and cleanliness influence moral judgment, but moderating variables and attributional processes need to be considered. Second, moral considerations have substantial effects on behavioural concomitants of disgust, such as facial expressions, economic games and food consumption. Third, while disgust involves a conservation concern, it can manifest itself in both liberal and conservative political attitudes. Overall, disgust can be considered to form part of a behavioural loss aversion system aimed at protecting valuable resources, including the integrity of one’s body. Recommendations are offered to investigate the role of disgust more rigorously in order to fully capture its role in moral life.     

Teacher Beliefs and Responses Toward Student Misbehavior: Influence of Cognitive Skill Deficits

This study aimed to examine whether having knowledge of student cognitive skill deficits changes teacher beliefs and responses in regard to classroom misbehavior. Teachers (N = 272) were randomly assigned to an experimental or control condition. Although teachers in both conditions read the same vignette describing a student's misbehavior, the experimental group also reviewed information about the student's cognitive skill deficits. Teachers provided with cognitive skill deficit information were, on average, less likely to believe the student had control over the misbehavior, suggesting perceptions of unintentionality. Furthermore, they were significantly more likely to indicate positive emotional responses. Results suggest that school psychologists may consider sharing cognitive skill deficits information with teachers who are working with students displaying challenging behavior.     

先前学业成就与学习动机、策略的关系:学业情绪的中介作用

采用整群抽样法抽取高中生670名,分别用学业情绪问卷、学习动机问卷和学习策略问卷来探讨学业情绪在先前学业成就与学习动机、学习策略之间的中介作用。以学业情绪的控制-价值理论和认知-动机模型为基础,运用偏差矫正百分位的非参数Bootstrap法对学业情绪的中介作用进行检验,结果发现:积极学业情绪在先前学业成就与学习策略、学习动机间起完全中介效应;消极学业情绪在先前学业成就与学习策略、学习动机间起部分中介效应。     

How do different humanness measures relate? Confronting the attribution of secondary emotions,human uniqueness,and human nature traits

The present research examines the relationship between the infrahumanization approach and the two-dimensional model of humanness: an issue that has received very little empirical attention. In Study 1, we created three unknown groups (Humanized, Animalized, and Mechanized) granting/denying them Human Nature (HN) and Human Uniqueness (HU) traits. The attribution of primary/secondary emotions was measured. As expected, participants attributed more secondary emotions to the humanized compared to dehumanized groups. Importantly, both animalized and mechanized groups were attributed similar amounts of secondary emotions. In Study 2, the groups were described in terms of their capacity to express secondary emotions. We measured the attribution of HN/HU traits. Results showed that the infrahumanized group was denied both HU/HN traits. The results highlight the importance of considering the common aspects of both approaches in understanding processes of dehumanization.     

Emotion recognition of facial expressions in adults with attention deficit hyperactivity disorder / Reconocimiento de emociones de expresiones faciales en adultos con trastorno de hiperactividad con déficit de atención

Various studies have indicated that children with ADHD have difficulties with the facial interpretation of affect. Research in the adult ADHD population overall is scarce. The present study explores how adults with ADHD react to a simple attention task and an emotion-containing task. Thirty adults clinically diagnosed with ADHD and 30 non-ADHD controls completed a computer-based task through a set of facial expressions standardized for Chile. The task was composed of two parts: first, a simple attention task with facial expressions; and second, a facial expression-labelling task. Reaction Time (RT) and Accuracy (Acc) of responses were evaluated. Participants with ADHD responded significantly faster and were significantly less accurate in both tasks compared to controls. Across both groups, emotion-specific errors increased in the facial expression of anger. Additionally, the ADHD group was significantly faster in responding for anger, but not for happiness or neutral expressions. Impulsivity commonly associated with ADHD may account for faster RT and lower Acc. Moreover, happiness may be more pleasant to identify than anger. These results are consistent with studies that have recorded greater Acc for positive emotions in comparison with negative emotions.     

Positive emotion infusions of elevation and gratitude: Increasing help-seeking intentions among people with heightened levels of depressive symptomatology

Three online studies assessed a new approach for increasing help seeking among people with depressive symptomatology (i.e. a positive emotion infusion, PEI). A PEI refers to the induction of positive emotion such that people’s mindsets – including perceptions of help-seeking – are temporarily altered. Study 1 (n = 382) indicated that help-seeking intentions are negatively correlated with depressive symptomatology and positively correlated with elevation and gratitude. Studies 2 and 3 implemented fully randomized experimental designs. In Study 2, two elevation-based (Study 2a, n = 285) and two gratitude-based (Study 2b, n = 338) emotion inductions increased levels of elevation and gratitude, respectively. Results of Study 3a (n = 390) indicate a causal relationship between experiencing the story-based elevation induction and increased help-seeking intentions. The two gratitude-based PEIs (Study 3b, n = 466) were unsuccessful at influencing help-seeking; auxiliary analyses indicate the possibility of iatrogenic effects. Overall, the potential of PEIs was indicated, as was need for caution.     

Partially testing a process model for understanding victim responses to an anticipated worksite closure

This study partially tested a recent process model for understanding victim responses to worksite/function closure (W/FC) proposed by Blau [Blau, G. (2006). A process model for understanding victim responses to worksite/function closure. Human Resource Management Review, 16, 12-28], in a pharmaceutical manufacturing site. Central to the model are the Kubler-Ross [Kubler-Ross, E. (1969). On death and dying. New York: Macmillan] grieving stages, which have not been formally measured and applied to downsizing research. Following Blau (2006), individual grieving stages were successfully measured and clustered into more general grieving categories, i.e., negative (denial, anger, bargaining depression) and positive (exploration, acceptance). Across four waves of data 53 respondents constituted the complete data sample. The Time 1 personal factors had minimal impact on any type of response. However, Time 1 situational factors did have an impact, paced by higher perceived contract violation leading to greater strain, work incivility, organizational deviance, and intent to sue employer, and lower transactional obligations and employer endorsement. Earlier Time 2 grieving stages were used as individual antecedents in regression analyses to explain Time 3 (N = 77) victim responses (general strain, work incivility, interpersonal deviance, organizational deviance, transactional obligations, relational obligations) and also Time 4 (N = 53) prior to closure responses (intent to sue employer, employer endorsement). Within negative grieving, results indicated that greater anger was the most influential grieving stage, since it led to greater strain, work incivility, organizational deviance, and intent to sue, as well as lower transactional obligations and lower endorsement. Within positive grieving acceptance was the most influential, since it led to lower strain, lower work incivility, lower organizational deviance, and lower intent to sue. Study limitations and future research issues are discussed.     

个体早期情绪唤起与自我决定及主观活力的关系

以量表测量法初步探索早期情绪唤起与成年后自我决定水平及主观活力之间的关系,试图寻找情绪对人格组织的核心作用的证据。研究发现：①个体在早期父母行为调控中的某些基本情绪的唤起可以有效预测其成年后的自我决定和主观活力水平。②个体早期抵触情绪唤起对其成年后的自我决定和主观活力具有消极作用,而非负性情绪唤起则具有积极作用。研究结果支持基本情绪理论关于情绪处于人格结构的核心地位的观点。
