An Electrophysiological Investigation of the Effects of Social Rejection on Self Control

Previous studies have shown that social rejection leads to impaired performance on a variety of tasks that require self control, including the Stroop color-word interference task; however, mechanisms underlying the effect remain to be elucidated. We attempted to clarify the effects of social rejection on self control resources by measuring event-related potentials (ERPs) during a computerized Stroop test. Stroop performance and ERPs from 54 participants in rejected, control, and accepted groups were analyzed. A significant difference in the pattern of results for the N450 ERP was found, with rejected participants showing less negativity on incongruent trials and more on congruent trials compared to accepted participants and controls. The results suggest social rejection reduces the engagement of cognitive control mechanisms, and are more consistent with a limited strength resource model than with limited capacity resource models that focus on limitations in attention.     

Networks of self-defining memories as a contributing factor to emotional openness

Emotional openness is characterised by a capacity to tolerate threatening self-relevant material and an interest towards new emotional situations. We investigated how specific networks of memories could be an important contributing factor to emotional openness. At Phase 1, participants completed measures of personality traits and emotional intelligence, described a self-defining memory, provided other memories associated with it, and rated the valence of each of their memories. A score assessing the complexity of this memory network, comprising the number of memories reported and their valence diversity, was created. Two weeks later, in laboratory, participants watched an anxiety-inducing film and took part in an interview assessing their emotional openness to the film. They completed a cognitive task before and after the film to measure ego depletion. Controlling for traits and emotional intelligence, memory network complexity was positively associated with emotional openness and negatively with ego depletion. The mental organisation of self-defining memories thus appears to be a critical factor contributing to emotional openness.     

Examining the consequences of exposure to racism for the executive functioning of Black students

Recent research has demonstrated that interracial interactions, reminders of stigmatized identities, and exposure to ambiguous racism can deplete the self-control resources of minority group members. In the current study we examined whether hearing blatant racism expressed in an interracial context would deplete the self-control of Black participants and whether this depletion would be moderated by participants’ level of racial centrality. After listening to a Black or a White confederate express either support for racial profiling (racist condition) or increased campus parking fees (neutral condition), Black participants completed a Stroop color-naming task to assess self-control depletion. Participants experienced self-control depletion following interracial encounters, regardless of whether the views expressed were racist. As expected, however, racial centrality moderated the depletion effect when racism was involved, with participants higher in centrality showing greater depletion following an encounter with racism from a White partner.     

Ego Depletion as a Measure of Emotion Processing Deficits among MUS Patients

Previous studies have found a link between emotion processing deficits and medically unexplained physical symptoms (MUS). The majority of previous studies have used self-report measures of emotional processing, with the majority focusing on alexithymia, and have produced inconsistent and contradictory results. In the present study, we investigated the role of emotion-processing deficits in MUS by assessing emotion regulation performance and the effects of performance on ego depletion. Participants with high or low levels of self-reported MUS watched emotion-evoking videos under instructions to allow or suppress their emotional reactions, and then performed an anagram task to measure their effort and perseverance. Contrary to the research with self-report measures, experimental analysis of emotion-processing revealed that MUS is correlated with the inability to regulate negative emotions. Unexpected self-regulatory tendencies of the participants with high symptom levels were discussed.     

无意识自我控制目标启动对自我损耗的补偿效应

本研究基于对无意识目标启动的研究,采用阈上、阈下启动方式探讨无意识目标启动对自我损耗的补偿作用。实验1发现,阈上无意识目标启动能够有效提高自我控制,促进自控表现。实验2发现,阈下无意识目标启动对自我损耗存在补偿效应。上述结果提示,通过无意识启动方式激活自我控制目标,可以克服自我损耗的不良效应,且无需意识参与。     

不合规任务与工作拖延行为的关系：自我损耗和主动性人格的作用

工作拖延行为是当今职场人士面临的普遍困扰之一。基于资源保存理论,本研究从不合规任务视角探究工作拖延行为的成因。对196位员工的两时点调查数据进行层次回归分析,结果表明：不合规任务正向预测员工工作拖延行为,自我损耗在不合规任务与工作拖延行为之间起着中介作用,主动性人格负向调节不合规任务与自我损耗的正向关系以及自我损耗的中介效应。以上结果对预防或降低工作拖延行为具有启发意义。     

Is ego depletion associated with increased distractibility? Results from a basketball free throw task

ObjectivesIt has been repeatedly demonstrated that athletes in a state of ego depletion do not perform up to their capabilities in high pressure situations. We assume that momentarily available self-control strength determines whether individuals in high pressure situations can resist distracting stimuli.Design/methodIn the present study, we applied a between-subjects design, as 31 experienced basketball players were randomly assigned to a depletion group or a non-depletion group. Participants performed 30 free throws while listening to statements representing worrisome thoughts (as frequently experienced in high pressure situations) over stereo headphones. Participants were instructed to block out these distracting audio messages and focus on the free throws. We postulated that depleted participants would be more likely to be distracted. They were also assumed to perform worse in the free throw task.ResultsThe results supported our assumption as depleted participants paid more attention to the distracting stimuli. In addition, they displayed worse performance in the free throw task.ConclusionsThese results indicate that sufficient levels of self-control strength can serve as a buffer against distracting stimuli under pressure.     

Can men do better if they try harder: Sex and motivational effects on emotional awareness

Research indicates that women are more emotionally aware than men. Motivation was investigated as a possible source of this sex difference. A total of 242 women and 74 men completed the first half of an emotional awareness test, the Level of Emotional Awareness Scale (LEAS; Lane & Schwarz, 1987), received either motivational or control instructions, and then completed the second half of the awareness scale. Participants' LEAS scores were compared via a 2 (sex) × 2 (condition) × 2 (time) General Linear Model Analyses of Variance. The motivational intervention was successful in significantly increasing both male and female participants LEAS scores, although women generally demonstrated greater emotional awareness than men. Furthermore, the LEAS scores of motivated men equalled those of women in the control condition, but the motivated men had to work significantly longer on the task to achieve this equality. Additional covar-iance analysis revealed that there were significant sex differences even after controlling for self-report and behavioural measures of motivation. We discuss the implications of these findings for understanding sex differences in emotional awareness.
