社会贴现:一种测量利他行为的新任务

社会贴现指的是人际交往过程中利他行为随着个人之间的社会距离增加而逐渐减少的现象。其研究任务首次将社会距离进行了量化,以个体愿意舍弃金额的数量换取他人获得定额的行为作为利他的标准。解释水平理论为社会贴现的内涵提供了理论基础,并解释了其内部机制。未来研究可以从自我结构的角度对社会贴现进行解释,也可以尝试使用社会支持相关的指标代替金钱,以避免金钱概念的启动所导致个体偏向自私的结论。     

Individual differences in emotional expression discrimination are associated with emotion label production in toddlers

It is possible that the visual discrimination of emotion categories and emotion word vocabulary develop via common emotion-specific processes. In contrast, it is possible that they develop with vocabulary development more generally. This study contrasts these two possibilities. Twenty-three 26-month-olds participated in a visual perceptual discrimination task involving emotional facial expressions. After familiarization to a 100% happy face, toddlers were tested for their visual preference for a novel sad face in a side-by-side presentation paired with the familiar happy face. Parental report was used to quantify production of emotion words and vocabulary generally. Visual preference for the novel emotion (sad) in the discrimination task correlated with emotion word vocabulary size but not with overall vocabulary size.     

Facets of conscientiousness and objective markers of health status

Objective: To examine the association between six facets of conscientiousness (self-control, order, industriousness, traditionalism, virtue, responsibility) and objective markers of health status, including adiposity, blood markers and physical performance.

Design: Cross-sectional analysis of participants from the health and retirement study (N = 12,188).

Main Outcome Measures: Adiposity (body mass index, waist circumference), blood markers (A1c, HDL cholesterol, total cholesterol, cystatin c, c-reactive protein) and physical performance (lung function, grip strength, walking speed).

Results: Four of the six facets of conscientiousness were associated with nearly all of the health markers: Self-control, organisation, industriousness and responsibility were related to lower adiposity, healthier metabolic, cardiovascular and inflammatory markers, and better performance on physical assessments. Traditionalism and virtue had fewer associations with these objective markers.

Conclusion: This research took a facet-level approach to the association between conscientiousness and objective markers of health status. This research builds on models of conscientiousness and health to suggest that, in addition to health-risk behaviours, facets of conscientiousness are associated with more favourable biomedical markers of health status.     

Parent reports of children’s working memory,coping, and emotional/behavioral adjustment in pediatric brain tumor patients: A pilot study

Neurocognitive problems in childhood survivors of brain tumors are well documented. Further, research has shown that problems in cognitive functioning may be associated with impairment in the use of complex strategies needed to cope with stress, including secondary control coping strategies (e.g., acceptance and cognitive reappraisal) which have been associated with fewer adjustment problems. The present study measured cognitive function, coping strategies, and adjustment in children ages 6–16 years at the time of brain tumor diagnosis and at two follow-up time-points up to 1 year post-diagnosis. In a prospective design, working memory was assessed in a total of 29 pediatric brain tumor patients prior to undergoing surgery, child self-reported coping was assessed at 6 months post-diagnosis, and parent-reported child adjustment was assessed at 12 months post-diagnosis. Significant correlations were found between working memory difficulties and secondary control coping. Secondary control coping was also negatively correlated with child attention and total problems. Regression analyses did not support secondary control coping mediating the association between working memory difficulties and child attention or total problems. These findings represent the first longitudinal assessment of the association between working memory, coping, and adjustment across the first year of a child’s brain tumor diagnosis and suggest a possible role for early interventions addressing both working memory difficulties and coping in children with brain tumors.

Parent–child interactions during traditional and interactive media settings: A pilot randomized control study

Parent–child interactions are pivotal for children's socioemotional development, yet might suffer with increased attention to screen media, as research has suggested. In response, we hypothesized that parent–child play on a tablet computer, as representative of interactive media, would generate higher‐quality parent–child interactions than toy play or watching TV . We examined the emotional availability of mothers and their 2‐year‐old child during the previous three contexts using a randomized crossover design (n = 22) in a laboratory room. Among other results, mothers were more sensitive and structuring during joint gaming on a tablet than when engaged in toy play or watching TV . In addition, mothers were more hostile toward their children during play with traditional toys than during joint tablet gaming and television co‐viewing. Such findings provide new insights into the impact of new media on parent–child interactions, chiefly by demonstrating that interactive media devices such as tablets can afford growth‐enhancing parent–child interactions.     

UNDERSTANDING THE CONNECTION BETWEEN ATTACHMENT TRAUMA AND MATERNAL SELF‐EFFICACY IN DEPRESSED MOTHERS

Maternal self‐efficacy predicts sensitive and responsive caregiving. Low maternal self‐efficacy is associated with a higher incidence of postpartum depression. Maternal self‐efficacy and postpartum depression can both be buffered by social support. Maternal self‐efficacy and postpartum depression have both been linked independently, albeit in separate studies, to the experience of violent trauma, childhood maltreatment, and spousal abuse. This study proposed a model in which postpartum depression mediates the relation between attachment trauma and maternal self‐efficacy, with emotional support as a moderator. Participants were 278 first‐time mothers of infants under 14 months. Cross‐sectional data were collected online. Mothers completed questionnaires on attachment trauma, maternal self‐efficacy, postpartum depression, and emotional support. A moderated mediation model was tested in a structural equation modeling framework using Mplus’ estimate of indirect effects. Postpartum depression fully mediated the relation between trauma and maternal self‐efficacy. Emotional support moderated only the pathway between postpartum depression and maternal self‐efficacy. Attachment trauma's implications for maternal self‐efficacy should be understood in the context of overall mental health. Mothers at the greatest risk for low maternal self‐efficacy related to attachment trauma also are those suffering from postpartum depression. Emotional support buffered mothers from postpartum depression, though, which has implications for intervention and future research.     

Effects of task-irrelevant emotional information on deception

Deception has been reported to be influenced by task-relevant emotional information from an external stimulus. However, it remains unclear how task-irrelevant emotional information would influence deception. In the present study, facial expressions of different valence and emotion intensity were presented to participants, where they were asked to make either truthful or deceptive gender judgments according to the preceding cues. We observed the influence of facial expression intensity upon individuals’ cognitive cost of deceiving (mean difference of individuals’ truthful and deceptive response times). Larger cost was observed for high intensity faces compared to low intensity faces. These results provided insights on how automatic attraction of attention evoked by task-irrelevant emotional information in facial expressions influenced individuals’ cognitive cost of deceiving.     

Successful management of automatic dysfunctional thoughts in the context of negative emotions

Background and objectives: Cognitive and affective overloads trigger automatic dysfunctional thoughts and undermine their voluntary management [ADTs; Beck, A. T. (1976). Cognitive therapy and the emotional disorders. New York: Meridian; Wegner, D. M. (1994). Ironic processes of mental control. Psychology Review, 101(1), 34–52]. Taking into account intense negative emotions as triggers for the ADTs, we explored whether context (i.e., social context) and emotional experience (i.e., emotional intensity) predict the successful management of ADTs. We also examine the moderating role of difficulties in emotional regulation strategies.

Method: Thirty-eight participants wrote in a personal online diary of at least 10 times in 40 weeks. We analyzed the conditions for managing ADTs by means of multilevel in stages models.

Results: Emotional intensity negatively predicted successful management of ADTs. Attempts to control ADTs and work context positively predicted successful management of ADTs. The negative relation between the emotional intensity and the management of ADTs was stronger as individuals were less aware of their own emotions, and was weaker as they had less clear representations of their own emotions. Superior access to emotion regulation strategies explained a stronger relationship between the work context and the successful management of ADTs.

Conclusions: We discuss theoretical and practical implications of the results.     

Decision mechanisms underlying mood-congruent emotional classification

There is great interest in understanding whether and how mood influences affective processing. Results in the literature have been mixed: some studies show mood-congruent processing but others do not. One limitation of previous work is that decision components for affective processing and responses biases are not dissociated. The present study explored the roles of affective processing and response biases using a drift-diffusion model (DDM) of simple choice. In two experiments, participants decided if words were emotionally positive or negative while listening to music that induced positive or negative mood. The behavioural results showed weak, inconsistent mood-congruency effects. In contrast, the DDM showed consistent effects that were selectively driven by an a-priori bias in response expectation, suggesting that music-induced mood influences expectations about the emotionality of upcoming stimuli, but not the emotionality of the stimuli themselves. Implications for future studies of emotional classification and mood are subsequently discussed.
