Emotion Regulation of Events Central to Identity and Their Relationship With Concurrent and Prospective Depressive Symptoms

Dispositional emotion regulation is related to the severity and maintenance of depressive symptoms. However, whether emotion regulation specific to an event highly central for an individual’s identity is predictive of depressive symptoms has not been examined. Nonclinical participants (N = 220) reported the extent to which they employed a selection of emotion regulation strategies when recalling low- and high-centrality events. Dispositional emotion regulation and depressive symptoms were also assessed. A 7-week follow-up was conducted. High-centrality events were associated with more emotion regulation efforts. Greater brooding and expressive suppression in relation to high-centrality memories predicted concurrent depressive symptoms after controlling for event valence and dispostional emotion regulation. Effects were absent for low-centrality memories. Emotion regulation in response to high-centrality memories did not predict depressive symptoms at follow-up beyond baseline depressive symptoms. Overall, the findings showed that maladaptive emotion regulation in response to memories of high-centrality events is important for explaining depressive symptomatology.     

从父母教育卷入到学业成就:自主支持与自主学习力的链式中介

家长教育卷入是为了提升学生的学业成就,但能否支持学生的自主学习从而提升其自主学习力,可能是提升学业成就的关键环节。研究将与自主学习相关的多种个人内部因素整合为自主学习力,对12万余名中小学生及其家长进行了大规模调查,建构了一个链式中介模型,分析显示父母教育卷入对学生学业成就的影响体现为两条路径:(1)父母主导路径:父母投入通过其自我报告的自主支持对学生学业成就产生显著影响;(2)学生发展路径:学生通过其所感知的父母自主支持提升其自主学习力,进而自主地促进其学业发展。研究提示,如何提高家长对学生“自主学习”的认识和支持能力,是家校协同促进学业发展的一个重要话题,也是保障“双减”不降学业成绩的一项关键举措。     

共情与中国民族音乐情绪识别的关系：来自ERP的证据

音乐情绪识别能力是利用音乐开展情绪调节的基本条件。传统的以五声音阶为基础的具有独特韵味的中国民族音乐反映了中国人独有的情感和价值观念, 在情绪调节和音乐治疗方面具有积极的作用, 是研究音乐情绪识别的有效音乐刺激。本研究采用跨通道情绪启动范式, 通过人际反应指针问卷筛选出高、低共情组被试各36人参加脑电实验, 考察共情能力对中国民族音乐情绪识别的影响。脑电数据显示, 在进行中国民族音乐情绪内隐识别时, 将宫调和羽调音乐作为启动刺激, 诱发了中期的P2、N400以及晚期正成分LPC (Late Positive Component)。低共情组P2和N400成分的波幅大于高共情组, 高共情组LPC成分的波幅大于低共情组。本研究第一次从电生理层面考察了不同共情能力的个体在进行中国民族音乐情绪识别时的神经反应差异。高低共情组在中国民族音乐情绪识别不同阶段的注意投入可能影响了其对音乐刺激的感受, 进而影响音乐情绪识别。     

The effect of gender on the N1-P2 auditory complex while listening and speaking with altered auditory feedback

The effect of gender on the N1-P2 auditory complex was examined while listening and speaking with altered auditory feedback. Fifteen normal hearing adult males and 15 females participated. N1-P2 components were evoked while listening to self-produced nonaltered and frequency shifted /a/ tokens and during production of /a/ tokens during nonaltered auditory feedback (NAF), frequency altered feedback (FAF), and delayed auditory feedback (DAF; 50 and 200 ms). During speech production, females exhibited earlier N1 latencies during 50 ms DAF and earlier P2 latencies during 50 ms DAF and FAF. There were no significant differences in N1-P2 amplitudes across all conditions. Comparing listening to active speaking, N1 and P2 latencies were earlier among females, with speaking, and under NAF. N1-P2 amplitudes were significantly reduced during speech production. These findings are consistent with the notions that speech production suppresses auditory cortex responsiveness and males and females process altered auditory feedback differently while speaking.     

Deviant ERP response to spoken non-words among adolescents exposed to cocaine in utero

Concern for the impact of prenatal cocaine exposure (PCE) on human language development is based on observations of impaired performance on assessments of language skills in these children relative to non-exposed children. We investigated the effects of PCE on speech processing ability using event-related potentials (ERPs) among a sample of adolescents followed prospectively since birth. This study presents findings regarding cortical functioning in 107 prenatally cocaine-exposed (PCE) and 46 non-drug-exposed (NDE) 13-year-old adolescents.PCE and NDE groups differed in processing of auditorily presented non-words at very early sensory/phonemic processing components (N1/P2), in somewhat higher-level phonological processing components (N2), and in late high-level linguistic/memory components (P600).These findings suggest that children with PCE have atypical neural responses to spoken language stimuli during low-level phonological processing and at a later stage of processing of spoken stimuli.     

Rethinking psychological approaches towards health promotion

The purpose of the present study was to test the factorial and discriminant validity of the Revised Illness Perception Questionnaire (IPQ-R), a measure of illness representations based on Leventhal, Meyer and Nerenz's Self-Regulation Theory, in a cervical screening context using confirmatory factor analysis. Six hundred and sixty women, who had attended a colposcopy clinic and were invited to re-attend, completed the IPQ-R. Data were analysed using covariance structure analysis. The adequacy of an a priori confirmatory factor analytic model that included seven dimensions of the cognitive illness representation: identity, timeline-acute/chronic, serious consequences, personal control, treatment control, illness coherence, and causal attributions, and one emotional representation factor was tested against the observed data. After the elimination of two items responsible for large standardised residuals and with low factor loadings, the model adequately accounted for covariances among the IPQ-R items according to multiple criteria for goodness-of-fit. Factor inter-correlations supported the discriminant validity of the constructs and the factors exhibited satisfactory composite reliability. A theoretically predictable pattern of relationships among the representation dimensions was evident. In particular, the control-related constructs and the illness coherence dimension were negatively related to other illness representation constructs. The present study provided confirmatory evidence using a robust hypothesis-testing framework to support the proposed structure of the illness representation dimensions in a cervical screening context.     

When does the brain distinguish between genuine and ambiguous smiles? An ERP study

Event-related brain potentials (ERPs) were recorded to assess the processing time course of ambiguous facial expressions with a smiling mouth but neutral, fearful, or angry eyes, in comparison with genuinely happy faces (a smile and happy eyes) and non-happy faces (neutral, fearful, or angry mouth and eyes). Participants judged whether the faces looked truly happy or not. Electroencephalographic recordings were made from 64 scalp electrodes to generate ERPs. The neural activation patterns showed early P200 sensitivity (differences between negative and positive or neutral expressions) and EPN sensitivity (differences between positive and neutral expressions) to emotional valence. In contrast, sensitivity to ambiguity (differences between genuine and ambiguous expressions) emerged only in later LPP components. Discrimination of emotional vs. neutral affect occurs between 180 and 430 ms from stimulus onset, whereas the detection and resolution of ambiguity takes place between 470 and 720 ms. In addition, while blended expressions involving a smile with angry eyes can be identified as not happy in the P200 (175–240 ms) component, smiles with fearful or neutral eyes produce the same ERP pattern as genuinely happy faces, thus revealing poor discrimination.

Event Centrality,Posttraumatic Cognitions,and the Experience of Posttraumatic Growth

This study tested the extent to which negative appraisals following traumatic events and the centrality of traumatic events predicted posttraumatic growth (PTG; Tedeschi &; Calhoun, 1996 Tedeschi, R. G. and Calhoun, L. G. 1996. The posttraumatic growth inventory: Measuring the positive legacy of trauma. Journal of Traumatic Stress, 9: 76–80. [Crossref] , [Google Scholar]). Participants were 405 undergraduates at a Midwestern university who reported experiencing at least one traumatic event. Regression analyses indicated that the centrality of the event was a significant predictor for all five domains of PTG. Negative appraisals of the world were related to some domains of growth, but neither negative cognitions about the self nor self-blame was a significant predictor of any of the growth domains. Interpretation of these results is considered in light of the consistencies with Janoff-Bulman's (2004) Janoff-Bulman, R. 2004. Posttraumatic growth: Three explanatory models. Psychological Inquiry, 15: 30–34. [Crossref], [Web of Science ®] , [Google Scholar] explanatory models of development of PTG.
