人类迅速高效识别语音情绪变化的神经生理机制仍是一个未解之谜。本研究试图通过对被试内隐加工语音情绪变化的即时脑电数据做时域和频域分析, 揭示语音情绪变化加工的神经生理机制。结果发现语音情绪变化诱发N2/P3复合成分, theta频段能量增加和试次间相位相干系数(ITC)增大, beta频段能量降低和ITC增大。这些神经生理指标受情绪变化模式的调节, 情绪变化越激烈, 诱发N2/P3复合成分的潜伏期越早, theta能量和相位变化更强烈。这些结果说明语音情绪变化加工是一个变化检测与整合的过程, 该过程主要由theta和beta频段能量和试次间相位的变化来实现。     

Parenting and Preschoolers' Symptoms as a Function of Child Gender and SES

ABSTRACT

Improving parental discipline practices is a central target of behavioral parent training programs, but little research has examined how discipline varies as a function of gender. Based on the assumption that socialization practices might be related to gender differences in psychopathology, we examined relations between parenting and problem behaviors in children. We predicted that parents would be overreactive toward children displaying symptoms inconsistent with gender stereotypes and lax towards those with gender stereotype-consistent behavior. Parents of 112 preschool-aged children reported on their children's externalizing and internalizing symptoms, and their own lax and overreactive parenting. As hypothesized, internalizing symptoms in girls and externalizing symptoms in boys predicted lax parenting, while externalizing behaviors in girls and internalizing symptoms in boys were associated with overreactive parenting. Exploratory analyses suggest that relations differed somewhat as a function of sociocultural status, pointing to the need for future studies to consider social context.     

Parental Emotion Coaching: Associations With Self-Regulation in Aggressive/Rejected and Low Aggressive/Popular Children

This study investigated associations between maternal and paternal emotion coaching and the self-regulation skills of kindergarten and first-grade children. Participants were 54 children categorized as either aggressive/rejected or low aggressive/popular by peer reports. Findings indicated a statistical trend for fathers of low aggressive/popular children to engage in more emotion coaching than fathers of aggressive/rejected children. Paternal emotion coaching accounted for significant variance in children's regulation of attention. Maternal emotion coaching moderated the relation between children's status and regulation of emotion. Findings suggest that interventions focused on parental emotion coaching may prove beneficial for increasing the self-regulation and attention skills of children with social and conduct problems.     

The role of the amygdala in emotional experience during retrieval of personal memories

ABSTRACT

Although the role of the amygdala in emotional memory retrieval has long been established, how such engagement varies depending on valence and retrieval context is less clearly understood. Participants retrieved personal memories associated with primarily positive, primarily negative, and mixed-valence images, pressing a button when successful. The button press divided trials into search and elaboration phases. Participants provided positivity and negativity ratings immediately following each trial, and then again in a post-retrieval survey. The relation between amygdala recruitment and emotionality exhibited a four-way interaction, with no other significant main effects or interactions. The interaction was driven by a temporal shift in the role of amygdala recruitment during retrieval of memories associated with mixed-valence images: Negativity ratings were supported more by search-related activity whereas positivity was more strongly associated with elaboration. Amygdala activity during retrieval relates to emotional experience in more complicated ways than previously understood. When participants were able to consider positive and negative aspects of the same event, amygdala recruitment during search and elaboration were associated with opposite behavioural effects. Such findings suggest that the amygdala may support distinct aspects of emotional experience for the same memory depending on when during retrieval it is recruited.     

Improving the Ability of Elementary School-Age Children to Identify Emotion in Facial Expression

The authors evaluated an intervention program developed to remediate children's deficits in reading emotions in facial expressions. Thirty children from 2 elementary schools in suburban Atlanta participated in 6 30-min sessions over 4 weeks in which they were taught to discriminate, identify, express, and apply facial expression cues. The ability to read emotion in facial expressions significantly improved for the intervention group compared with the control group. Improvement on identifying facial expressions was associated with increased feelings of lower social anxiety and higher self-worth for girls. Boys' self-concept was negatively related to improvement. On the basis of the results, the authors suggested that structured interventions like the present one could be used to improve students' nonverbal processing abilities within public school settings, but with some cautions regarding the impact of new learning for boys.     

Social Adjustment,Academic Adjustment,and the Ability to Identify Emotion in Facial Expressions of 7-Year-Old Children

The authors aimed to examine the possible association between (a) accurately reading emotion in facial expressions and (b) social and academic competence among elementary school-aged children. Participants were 840 7-year-old children who completed a test of the ability to read emotion in facial expressions. Teachers rated children's social and academic behavior using behavioral rating scales. The authors found that children who had more difficulty identifying emotion in faces also were more likely to have more problems overall and, more specifically, with peer relationships among boys and with learning difficulties among girls. Findings suggest that nonverbal receptive skill plays a significant role in children's social and academic adjustment.     

Maternal Socialization Goals,Parenting Styles,and Social-Emotional Adjustment Among Chinese and European American Young Adults: Testing a Mediation Model

The authors compared the associations among perceived maternal socialization goals (self-development, filial piety, and collectivism), perceived maternal parenting styles (authoritative, authoritarian, and training), and the social-emotional adjustment (self-esteem, academic self-efficacy, and depression) between Chinese and European American young adults. The mediation processes in which socialization goals relate to young adults’ adjustment outcomes through parenting styles were examined. Results showed that European American participants perceived higher maternal self-development socialization goals, whereas Chinese participants perceived higher maternal collectivism socialization goals as well as more authoritarian parenting. Cross-cultural similarities were found in the associations between perceived maternal authoritative parenting and socioemotional adjustment (e.g., higher self-esteem and higher academic self-efficacy) across the two cultural groups. However, perceived maternal authoritarian and training parenting styles were found only to be related to Chinese participants’ adjustment (e.g., higher academic self-efficacy and lower depression). The mediation analyses showed that authoritative parenting significantly mediated the positive associations between the self-development and collectivism goal and socioemotional adjustment for both cultural groups. Additionally, training parenting significantly mediated the positive association between the filial piety goal and young adults’ academic self-efficacy for the Chinese group only. Findings of this study highlight the importance of examining parental socialization goals in cross-cultural parenting research.     

Normative Influences on Secondary Disturbance: The Role of Social Expectancies

A “new wave” within psychotherapy has introduced the concept of acceptance into people's emotional repertoires. Accepting unpleasant emotional states has been demonstrated as an important pathway towards reducing secondary disturbances and improving emotional and psychological functioning. What is often overlooked, however, is whether this move towards acceptance is reinforced within the social and cultural contexts in which people experience their emotional states. Our research has begun to explore the contribution that normative influences make to secondary disturbance, specifically the perception that feeling happy is a desired state, and that experiencing and expressing negative emotions is undesirable and unacceptable to others. We review evidence here that these perceived “social expectancies” are associated with increased negative emotionality and depression, and reduce well‐being. Furthermore, we highlight that the effects of social expectancies are more apparent in Australia than Japan, consistent with the view that a higher premium is placed on happiness within Australia. We also review experimental evidence that social messages that reinforce these social expectancies serve to increase secondary disturbances. The implications of taking a social perspective on emotion regulation and dysfunction, and specifically implications for promoting happiness and acceptance in the field, are discussed.     

Does the Thought Count? Gratitude Understanding in Elementary School Students

Gratitude, although studied throughout history by scholars from diverse backgrounds, has been largely understudied in psychology until recently. The psychological literature on gratitude is expanding, but it is still particularly limited with children. The authors compared younger (first- and second-grade students; n = 30) and older (fourth- and fifth-grade students; n = 27) children on gratitude-related ratings surrounding gift giving vignettes that included either a desirable (e.g., a birthday cupcake) or an undesirable (e.g., a melted ice cream cone) gift. Empathy was also measured. Hierarchical regressions revealed different patterns of predictors for desirable and undesirable gifts. For desirable gifts, liking significantly predicted gratitude and liking predicted effort. For undesirable gifts, older children and those who perceived the target as liking the gift more predicted higher gratitude ratings. Finally, higher gratitude rating predicted both higher ratings of giver effort (i.e., intention or how hard did the giver try to give a nice gift) and liking of the undesirable gifts. More research on children's understanding of gratitude is needed but these results suggest that school-aged children take into account givers’ intentions and thoughts behind gift giving in determining feelings of gratitude. Limitations and directions for future research are also discussed.
