晚期正成分的时间-空间迁移模式在情绪调节发展研究中的应用

近二十年,使用认知神经科学手段探讨情绪调节成为了研究的热点。晚期正成分(Late Positive Potential,LPP)是情绪调节脑电研究中的一个典型成分,在不同的时间窗中分析LPP的波幅的变化及其优势激活脑区的迁移能够反映情绪调节加工过程中个体由对情绪刺激的感知到相应的认知调控过程的转变。LPP的时间-空间迁移模式被应用于情绪调节的发展研究,揭示从童年到青少年再到成年期个体情绪的潜在神经机制。研究者关注幼儿期、童年期、青少期、成人期个体在情绪调节加工过程中LPP波幅的变化及其时间-空间迁移模式特征,把不同年龄段个体情绪调节的发展特点与其大脑关键脑区(主要是前额叶)发育状况进行联系,为儿童身体发育和心理发展的主题提供更多的证据支持。未来的研究应加强对LPP在异常发展研究中应用,关注大脑发育与激素变化对LPP变化的影响,并加强对LPP调节效应的个体差异等问题的探讨。     

Searching for commonalities in human judgement: The parametric unimodel and its dual mode alternatives

The question of why even a minimal ingroup is typically evaluated more positively than the respective outgroup has stimulated extensive theoretical and empirical work in social psychology. Integrating findings from various domains of research, this chapter summarises a comprehensive research programme that focuses on cognitive rather than motivational factors that contribute to positive ingroup distinctiveness. More specifically, evidence is presented showing that (a) there is a positive ingroup default, such that novel ingroups are immediately associated with positive affect; (b) people make inferences from the self in order to define their novel groups; and (c) this process of using the self as a means of cognitive structuring is based on heuristic rather than systematic information processing. Implications for our understanding of the role of self in intergroup evaluations and of factors determining ingroup favouritism in both minimal and real groups are discussed.     

Affective mediators of the relationship between trait emotional intelligence and life satisfaction in young adults

This study examined the affective mediators of the relationship between trait emotional intelligence and life satisfaction in young adults and the widespread or limited affective mediators between the different groups in demographic factors, e.g., gender, students and non-students, family conditions. Six hundred and twenty participants completed the Wong Law Emotional Intelligence Scale, the Satisfaction with Life Scale and the Positive Affect and Negative Affect Scale. Results using structural equation modeling showed that both positive affect and negative affect acted as mediators of the relationship between trait EI and life satisfaction and the indirect effect of trait EI on life satisfaction via positive affect was stronger than that via negative affect. Moreover, multi-group analyses found that the paths did not differ by gender and family conditions, but positive affect was more strongly associated with students’ life satisfaction, compared to non-students. Implications and limitations of the findings are discussed.     

Are individual differences in appetitive and defensive motivation related? A psychophysiological examination in two samples

Appetitive and defensive motivation account for a good deal of variance in personality and mental health, but whether individual differences in these systems are correlated or orthogonal has not been conclusively established. Previous investigations have generally relied on self-report and have yielded conflicting results. We therefore assessed the relation between psychophysiological indices of appetitive and defensive motivation during elicitation of these motivational states: specifically, frontal electroencephalogram asymmetry during reward anticipation and startle response during anticipation of predictable or unpredictable threat of shock. Results in a sample of psychopathology-free community members (n=63), an independent sample of undergraduates with a range of internalising symptoms (n=64), and the combination of these samples (n=127) revealed that differences in responding to the two tasks were not significantly correlated. Average coefficients approached zero in all three samples (community: .04, undergraduate: ?.01, combined: .06). Implications of these findings for research on normal and abnormal personality are discussed.     

How counting represents number: what children must learn and when they learn it

This study compared 2- to 4-year-olds who understand how counting works (cardinal-principle-knowers) to those who do not (subset-knowers), in order to better characterize the knowledge itself. New results are that (1) Many children answer the question "how many" with the last word used in counting, despite not understanding how counting works; (2) Only children who have mastered the cardinal principle, or are just short of doing so, understand that adding objects to a set means moving forward in the numeral list whereas subtracting objects mean going backward; and finally (3) Only cardinal-principle-knowers understand that adding exactly 1 object to a set means moving forward exactly 1 word in the list, whereas subset-knowers do not understand the unit of change.     

Averaging and summation: Positivity and choice as a function of the number and affective intensity of life events

Six experiments were reported that investigated individuals’ perceptions of positive life events and their preferences for options presenting different combinations of positive event frequency and magnitude. Results revealed that individuals often responded to the average level of positivity and preferred less (versus more) positive events and supported the averaging/summation model of life event integration. Results revealed, for example, that participants felt more positive affect when they were exposed to a highly positive event than a highly positive plus mildly positive one. When the events had similar affective intensities, however, summation effects were obtained—more was better. In demonstrating averaging and summation effects, we delineated situations in which more positive life events can be better (summation effects) and situations in which more can be worse (averaging effects). Results also ruled out several alternative accounts, including the peak-end rule, economic, affective forecasting, and an assimilation/contrast interpretation.     

Counting blessings in early adolescents: An experimental study of gratitude and subjective well-being

The development and manifestation of gratitude in youth is unclear. We examined the effects of a grateful outlook on subjective well-being and other outcomes of positive psychological functioning in 221 early adolescents. Eleven classes were randomly assigned to either a gratitude, hassles, or control condition. Results indicated that counting blessings was associated with enhanced self-reported gratitude, optimism, life satisfaction, and decreased negative affect. Feeling grateful in response to aid mediated the relationship between experimental condition and general gratitude at the 3-week follow-up. The most significant finding was the robust relationship between gratitude and satisfaction with school experience at both the immediate post-test and 3-week follow-up. Counting blessings seems to be an effective intervention for well-being enhancement in early adolescents.     

Empowering Community Settings: Agents of Individual Development, Community Betterment, and Positive Social Change

The pathways and processes through which empowering community settings influence their members, the surrounding community and the larger society are examined. To generate the proposed pathways and processes, a broad range of studies of community settings were reviewed, in the domains of adult well-being, positive youth development, locality development, and social change. A set of organizational characteristics and associated processes leading to member empowerment across domains were identified, as well as three pathways through which empowering settings in each domain contribute to community betterment and positive social change. The paper concludes with an examination of the ways that community psychology and allied disciplines can help increase the number and range of empowering settings, and enhance the community and societal impact of existing ones.

The role of gratitude in the development of social support, stress, and depression: Two longitudinal studies

In two longitudinal studies, the authors examined the direction of the relationships between trait gratitude, perceived social support, stress, and depression during a life transition. Both studies used a full cross-lagged panel design, with participants completing all measures at the start and end of their first semester at college. Structural equation modeling was used to compare models of direct, reverse, and reciprocal models of directionality. Both studies supported a direct model whereby gratitude led to higher levels of perceived social support, and lower levels of stress and depression. In contrast, no variable led to gratitude, and most models of mediation were discounted. Study 2 additionally showed that gratitude leads to the other variables independently of the Big Five factors of personality. Overall gratitude seems to directly foster social support, and to protect people from stress and depression, which has implications for clinical interventions.     

Fear and positive affectivity in infancy: convergence/discrepancy between parent-report and laboratory-based indicators

This study examined convergence between indicators of infant temperament derived via parent-report and those obtained in the context of structured laboratory observations. Discrepancies between scores resulting from these methodological approaches were examined in an attempt to explain these differences by considering multiple reporter (i.e., parent) characteristics. Convergence between the two sources of information was hypothesized; however, discrepancies were also expected. This study was aimed at examining whether increased maternal depression and low parenting self-efficacy were related to higher levels of infant fear and decreased positive affectivity, as reported by mothers, relative to the scores derived from the laboratory procedure. Results indicated that the fear scores based on parent-report and structured observations, respectively, were significantly correlated; however, the correlation for smiling and laughter scores did not reach statistical significance. Furthermore, parents higher in negative affect reported a higher level of fear for their infants, relative to the results of the laboratory observation.
