본 논문은 정서-주의 태스크를 수행할 때의 신경학적, 행동학적 반응이 정서조절 능력을 반영할 수 있는지를 측정하였다. 이를 위해, 건강한 성인 남녀 19명을 대상으로 3일에 걸쳐 1일 1회씩 동일 시간대에 정서-주의 상호작용이 요구되는 실험을 수행하였다. 이 실험을 통해 정서를 유발하는 비디오를 보여주기 전과 후, 정서-주의 태스크를 수행할 때의 EEG와 반응시간이 측정되었다. ERP P100과 P300 성분 간의 밀접한 상관관계가 나타났으며, P100 진폭이 높을수록 P300 잠재기가 길게 나타났다. 또한 P300 잠재기가 길수록 반응시간이 길게 나타났다. 또한, 정서-주의 태스크를 수행할 때 ERP 성분과 반응시간에 개인별 차이가 존재하였다. 정서유발을 위해 사용된 비디오 자극의 유형에 관계없이 ERP 성분의 낮은 진폭과 빠른 잠재기를 나타낸 집단이 더 빠른 반응시간을 나타내었다. 이러한 반응특성은 목표인식에 대한 성급한 반응으로 해석될 수 있으며, 낮은 정서 조절력과 관련이 있다고 할 수 있다.

The purpose of this study was to examine the relationships between preschooler's sex, effortful control, working memory, and emotion regulation. The moderating effect of sex in the influences of effortful control and working memory on emotion regulation was also investigated. Eighty-eight children from the ages of 3 to 5 years participated in this study. A working memory task of the Korean Wechsler Intelligence Scale for Children IV(K-WISC-IV; Kwak, Oh, & Kim, 2011) was administered to the children. Their parents completed a very short form of the Children's Behavior Questionnaire(Putnam & Rothbart, 2006) and Emotion Regulation Checklist(Shields & Cicchetti, 1997). The results indicated that effortful control significantly predicted emotion regulation. Additionally the moderating effect of sex on the relationship between working memory and emotion regulation was significant. Specifically, the influence of working memory on emotion regulation was significant only in boys, but not in girls. This result suggested that effortful control has an effect on emotion regulation in a stable manner whereas working memory has different effects on the influence of emotion regulation according to sex.

본 연구는 정서조절 설문지와 정서조절 과제를 사용하여, 정서조절 전략인 재해석과 억제에 대한 경향성과 사용이 일치하는지 탐구하였다. 또한, 성격특성, 회복탄력성 척도를 사용하여 정서조절의 효과성과 관련이 있는 개인 내 변인들을 탐색하였다. 연구 대상은 60명의 여자 대학생으로, 연구 1에서는 40명을 집단 간 설계로 재해석과 억제 집단에 각각 20명씩 무작위로 할당하였고, 연구 2에서는 실험 1에 참가하지 않은 여자 대학생 20명을 대상으로 집단 내 설계로 재해석과 억제 과제를 실시하였다. 연구 결과, 정서조절 과제를 통한 재해석 전략과 억제 전략의 사용은 부정적인 정서를 효과적으로 감소시킨 것으로 나타났다. 둘째, 과제를 통해 측정된 정서조절의 사용과 자가보고 설문지를 통해 측정된 정서조절 경향성은 일치하지 않았다. 셋째, 억제 전략의 사용은 성격 특성의 외향성과 연관되는 것으로 나타났다. 본 연구의 결과는 실제 사용하는 전략과 정서조절 전략에 대한 주관적 평가가 일치하지 않을 수 있음을 시사한다. 또한, 본 연구 결과는 억제에 비해 재해석이 기능적이라고 주장하는 기존의 연구 결과를 지지한다.

The purposes of this study were to explore the gender differences in children's social competence, emotional regulation and maternal parenting behaviors, and to investigate differences between boys and girls in the interrelationships between these kinds of variables. The participants were 214 children in 4 to 6 grades and their teachers from one elementary school in Seoul. The data were analyzed using descriptive statistics, t-test, Pearson's correlations, and multiple regressions. The results were as follows: There were statistically significant gender differences in the children's social competence, emotional regulation and maternal parenting behaviors. Children's negative emotion explained boys' and girls' peer social skills, frustration tolerance, and task orientation. Children's positive emotion regulation explained boys' and girls' peer social skills, assertive social skills, and task orientation. Boys, who perceived less maternal supervision, displayed less assertive social skills and task orientation.

The process model of emotion regulation suggests that cognitive reappraisal and expressive suppression engage at different time points in the regulation process. Although multiple brain regions and networks have been identified for each strategy, no articles have explored changes in network characteristics or network connectivity over time. The present study examined (a) the whole-brain network and six other resting-state networks, (b) their modularity and global efficiency, which is an index of the efficiency of information exchange across the network, (c) the degree and betweenness centrality for 160 brain regions to identify the hub nodes with the most control over the entire network, and (d) the intra-network and inter-network functional connectivity (FC). Such investigations were performed using a traditional large-scale FC analysis and a relatively recent sliding window correlation analysis. The results showed that the right inferior orbitofrontal cortex was the hub region of the whole-brain network for both strategies. The present findings of temporally altering functional activity of the networks revealed that the default mode network (DMN) activated at the early stage of reappraisal, followed by the task-positive networks (cingulo-opercular network and fronto-parietal network), emotion-processing networks (the cerebellar network and DMN), and sensorimotor network (SMN) that activated at the early stage of suppression, followed by the greater recruitment of task-positive networks and their functional connection with the emotional response-related networks (SMN and occipital network). This is the first study that provides neuroimaging evidence supporting the process model of emotion regulation by revealing the temporally varying network efficiency and intra- and inter-network functional connections of reappraisal and suppression.

We study emotion regulation in a distant CABLe (Collaborative Argumentation Based-Learning) setting at university. We analyze how students achieve the group task of synthesizing the literature on a topic through scientific argumentation on the institutional Moodle's forum. Distinguishing anticipatory from reactive emotional regulation shows how essential it is to establish and maintain a constructive working climate in order to make the best out of disagreement both on social and cognitive planes. We operationalize the analysis of anticipatory emotional regulation through an analytical grid applied to the data of two groups of students facing similar disagreement. Thanks to sharp anticipatory regulation, group 1 solved the conflict both on the social and the cognitive plane, while group 2 had to call out for external regulation by the teacher, stuck in a cyclically resurfacing dispute. While the institutional digital environment did afford anticipatory emotional regulation, reactive emotional regulation rather occurred through complementary informal and synchronous communication tools. Based on these qualitative case studies, we draw recommendations for fostering distant CABLe at university.

Objective: This study analyzed mother-child interactions in a stressful situation each second by mother's emotional regulation level. Methods: The study was conducted with 16 mothers and their 5-year-old children playing a teaching task for 15 min. During the interactions, the participants were videotaped and examined. Furthermore, qualitative analysis was used for analyzing mother-child interactions in detail by creating a situation that maximizes the stress and frustration of the mother and child. Results: The results showed that maternal humor and affection were significantly related to child positive emotion and that maternal coaching closely correlated with the child pride, pleasure, and whining. Additionally, maternal intrusive behavior showed a positive correlation with child anger. Lastly, mothers with higher levels of emotional regulation more often expressed affection to their children. They were more actively involved in the tasks and used fewer positive or negative directive expressions. Therefore, children of this group expressed more positive emotions. Conclusion: These findings suggests that programs improving parental emotional reaction and emotion regulation should be developed.

Objectives Maltreatment experiences can alter brain function related to emotion regulation, such as cognitive reappraisal. While dysregulation of emotion is an important risk factor to mental health problems in maltreated people, studies reported alterations in brain networks related to cognitive reappraisal are still lacking. Methods Twenty-seven healthy subjects were recruited in this study. The maltreatment experiences and positive reappraisal abilities were measured using the Childhood Trauma Questionnaire-Short Form and the Cognitive Emotion Regulation Questionnaire, respectively. Twelve subjects reported one or more moderate maltreatment experiences. Subjects were re-exposed to pictures after the cognitive reappraisal task using the International Affective Picture System during fMRI scan. Results The maltreatment group reported more negative feelings on negative pictures which tried cognitive reappraisal than the no-maltreatment group (p < 0.05). Activities in the right superior marginal gyrus and right middle temporal gyrus were higher in the maltreatment group (uncorrected p < 0.001, cluster size > 20). Conclusions We found that paradoxical activities in semantic networks were shown in the victims of maltreatment. Further study might be needed to clarify these aberrant functions in semantic networks related to maltreatment experiences.

Cardiovascular, respiratory and electrodermal responses to acute stress episodes modeled by combined presentation of intense white noise and performance of word recognition task with noise background were studied in 15 college students. Experimental procedure consisted in sessions with white noise, word recognition task presentation with noise background and test with noise background. Recorded physiological variables were analyzed in terms of their sensitivity to detect activation of sympathetic and parasympathetic branches of autonomic nervous system and thus reflect autonomic arousal level during shout-term stress-inducing experimental manipulations. It was shown that performance of effortful mental task with noise background elicited significant physiological responses typical for active coping behavior, namely electrodermal arousal and increased cardiovascular activity. this response profile was more profound as compared to white noise only or attending task in noise background. However, all physiological responses were mostly phasic, without long-term tonic changes, since almost all variables recovered to their initial baseline levels, suggesting that dominant autonomic mechanisms in transient acute stress episodes were of parasympathetic nature (withdrawal in stress with subsequent activation in restoration period), while sympathetic contribution was not long-lasting. Nevertheless, increased number of stressors and their longer exposure may result in higher profile of tonic sympathetic arousal and reduced functional role of vagal mechanisms in autonomic balance regulation.

본 연구에서는 남성과 여성에 있어서 정서적 자극에 대한 기억이 다른지를 알아보고자 하였다. 또한 제시되는 자극의 기억을 측정할 것이라는 기억지시문을 주고, 또한 자극제시 후 곧바로 자유회상의 방법으로 기억을 측정함으로써 정서적 자극으로 유발된 정서의 표현을 조절할 필요성을 가능한 최소화시켰다. 그리고 남성과 여성의 정서적 자극과 중성적 자극에 대한 기억을 측정함으로써 선행사건초점 정서조절 과정에 의해 남성들의 정서적 자극에 대한 기억이 손상됨을 밝히고자 하였다. 전체적으로 여성들이 남성들보다 제시된 자극에 대하여 더 많이 기억하고 있었으며, 특히 중성적 자극보다 정서적 자극에 대해 남성들보다 더 많은 내용을 회상하였다. 회상내용을 중심적 요소에 대한 기억과 지엽적 요소에 대한 기억으로 나누어 남녀 차이를 분석해본 결과, 여성들은 정서적 자극의 중심적 요소에 대하여 중성적 자극보다 더 많이 기억하였으나 남성들은 정서적 자극과 중성적 자극에 대한 중심적 요소에 대한 기억차이가 나타나지 않았다.
