The conceptual model of emotion regulation (ER) of Gross and Thompson (2007) introduces families of ER strategies ordered on a temporal scale. This scale has been attributed implications both for the grouping strategies but also for the neurocognitive processing. The two event-related potential (ERP) studies of emotional regulation presented here focus on emotional regulation at different temporal distances, as well as, different stages of cognitive processing. Trying to discern if various neural processes could be disentangled by looking at different stages of the late positive potential (LPP). The theoretical background begins with the neurocognitive science of emotionality and visits cognitive processing at both early and late stages before summating results of the contemporary research of emotional regulation. 39 participants were enrolled within the two experiments aiming to compare the efficiency of different strategies in reducing negative social emotion induced by photographs of angry faces. Technical difficulties discourage conclusions about how temporal distancing is most effectively adapted. Results suggest self-focused distancing strategies are more effective than situation-focused reappraisal and could be preferred for therapeutic purposes based on greater observed LPP effect.

Contexte : La régulation émotionnelle est un ensemble de processus responsables du contrôle, de l’évaluation et de l’ajustement des émotions dans un objectif. Les résultats d’imagerie fonctionnelle s’accordent sur l’implication des structures frontales et limbiques tandis que les résultats en neurophysiologie, encore rares, suggèrent un rôle du rythme alpha dans l’induction émotionnelle et du rythme thêta dans la régulation. Objectifs et hypothèses : Notre objectif était d’étudier le rythme thêta et alpha pendant la réévaluation de stimuli déplaisants. Nous avons émis l’hypothèse que l’activité alpha serait modulée lors de l’induction émotionnelle seulement tandis que l’activité thêta préfrontale serait positivement corrélée à une régulation réussie. Méthode : Vingt-quatre participants sains ont été enregistrés avec 64 électrodes EEG alors qu’ils regardaient passivement ou réévaluaient des images négatives et neutres. Les rythmes thêta et alpha ont été comparés lors de l’induction émotionnelle puis dans les conditions de maintien, de diminution et d’augmentation de l’émotion, et une localisation de la source a estimé les générateurs. Résultats : Le rythme alpha était non sensible à l’induction et à la régulation. L’activité thêta était systématiquement plus élevée dans la condition de régulation à la hausse que dans la condition de maintien (p=.04) principalement au début de la régulation (1-3 sec) pour thêta bas et plus tard (5-7 sec) pour le thêta haut avec comme générateur du thêta bas le gyrus frontal moyen et le cortex cingulaire antérieur dorsal. Conclusion : Le rythme thêta était impliqué dans les processus de réévaluation à la hausse de l’émotion. / Context: Emotion regulation is a set of processes responsible for controlling, evaluating and adjusting reactions to achieve a goal. Results derived from magnetic resonance imaging agreed on the involvement of frontal and limbic structures in this process. Findings using cognition and physiology interactions are still scarce but suggest a role for alpha rhythm in emotional induction and theta in regulation. Objectives and hypotheses: Our goal was to investigate theta and alpha rhythm during the reappraisal of aversive stimuli. We hypothesized that an implication of alpha rhythm in emotional induction only and an increase in prefrontal theta rhythm positively correlated with successful regulation. Method: Twenty-four healthy participants were recorded with 64 EEG electrodes while asked to passively watch or reappraise negative pictures. Theta and alpha rhythms were compared across maintain, decrease and increase regulation conditions, and a source localization estimated the generators. Results: Theta activity was consistently higher in the upregulation than in the maintenance condition (p=.04) for the entire control period, but mainly at the beginning of regulation (1-3 sec) for low-theta and later (5-7 sec) for high-theta. Moreover, our results confirm that a low-theta generator correlated with mainly the middle frontal gyrus and the dorsal anterior cingulate cortex during upregulation. Theta was sensitive to emotion upregulation, whereas the alpha oscillation was non-sensitive to emotion induction and regulation. Conclusion: The low-theta rhythm was involved explicitly in emotion upregulation processes that occur at a definite time during reappraisal, whereas the alpha rhythm was not altered by emotion induction and regulation.

Parenting stress has been closely studied largely in relation to implications for the parent and implications for children. Emotion regulation refers to the processes in which one interprets and experiences emotions. Little has been done examining how parenting stress and mother emotion regulation relates to dyadic interaction between mother and child. Because of the compounding nature of stress as identified in the ABCX model of family stress and resilience theory, understanding parenting stress in its entirety and how mothers experience and deal with said parenting stress is crucial to understanding family processes, as it is not possible to partition the mother and child into separate spheres, per family systems theory. Maternal parenting behaviors cannot be conceptualized in isolation of the mother-child dyad; therefore, it is important to understand maternal processes and behaviors that relate to parenting and also the dyad. The current study examined the moderating impact of maternal emotion regulation on the relation between maternal parenting stress and three facets of dyadic interaction, including conflict, cooperation, and reciprocity. Mothers and their 4-5.5-year-old children (n=116) participated in a teaching task wherein mothers instructed their child to build figures with interlocking blocks based on provided images. Six hypotheses were examined. Regression analyses revealed that neither maternal cognitive reappraisal nor maternal emotion suppression moderated the relation of total parenting stress to parent-child dyadic interaction. However, preliminary correlation analyses revealed that dyads with boys experienced higher scores of dyadic conflict. Boys in the sample were also younger than girls. Considerations for lack of significant findings are explored including the role of maternal characteristics, child characteristics, and goodness-of-fit. Future exploration is necessary to examine how parent characteristics like maternal emotion regulation and parenting stress may relate to dyadic interactions with children. / M.S. / Most of the research on parenting stress, which is the stress that parents may feel related to their roles as parents, examines how it is related to parenting behavior or directly to their children’s behavior. There is little research on how parenting stress and maternal emotion regulation, which how mothers control their emotions, relate to dyadic interactions between mothers and children. Theories of family stress suggest that stress builds over time; therefore, it is important to understand all aspects of parenting stress. When any family member experiences stress, theories suggest that their stress can affect other family members. Maternal parenting behaviors, however, cannot be viewed separately from patterns of dyadic interaction between mothers and children; it is important to understand how maternal characteristics, including parenting stress and emotion regulation, relate to patterns of dyadic mother-child interaction. The current study examined how maternal parenting stress related to three types of dyadic interaction, including conflict, cooperation, and reciprocity. It was expected that how parenting stress would relate to dyadic interaction would be different depending on how mothers reported regulating their emotions. Mothers and their 4-5.5-year-old children (n=116) participated in a building task where mothers taught children how to make figures out of interlocking blocks based on pictures provided to mothers. Findings showed that maternal emotion regulation did not increase or decrease how maternal parenting stress related to dyadic interaction between mothers and children. Dyads with boys, however, experienced higher scores of dyadic conflict, and boys in the sample were also younger than girls. Future exploration is needed to examine how parent characteristics like maternal emotion regulation and parenting stress may relate to dyadic interactions between mothers and children.

研究目的：再評估策略在清醒時是廣為使用且能夠有效降低負向情緒的方法之一。若個人在睡前使用，應預期也能降低情緒而促進入睡。然而，調查研究卻發現睡前使用再評估策略的習慣與入睡歷程未有預期的正向關連。研究者回顧發現，再評估策略可能包含了各種不同性質的次分類，高控制性的再評估策略可能會導致過度激發狀態，影響入睡。本研究目的即在於比較控制性高（改變對當下情境的詮釋）與低（接受）的再評估策略，讓兩組受試者在使用不同策略後嘗試入睡，並詢問其入睡歷程下的主觀入睡經驗。預期高控制再評估策略會導致受試者較高的認知激發狀態，而在階段二睡眠喚醒後有較多人自陳仍有思考活動，較少人自認已經睡著，以釐清入睡前使用不同次分類再評估策略所造成的控制性認知活動，可能對入睡歷程帶來的影響。 研究方法：本研究共招募26名受試者，並隨機分派至接受組（13人，7位男性，6位女性，平均年齡23.6歲）與對當下情境詮釋組（13人，男性6位，女性7位，平均年齡24.9歲）。受試者皆須依序經過中性情境以及情緒誘發情境兩個夜晚。在情緒誘發情境下，主試者會對其表現給予負向回饋以引發情緒，接著依不同組別要求受試者在睡前使用不同再評估策略來調適情緒，隨後嘗試入睡。同時，主試者會在睡前測量受試者的認知激發狀態，並於進入階段二睡眠後，即時喚醒詢問其入睡歷程意識經驗，包含主觀入睡知覺（自評睡著與否）、思考活動（是否仍有思考）等。 研究結果：本研究結果顯示，睡前使用高控制性策略，的確造成較高的入睡前控制活動，形成較高認知激發狀態，影響入睡歷程。在階段二睡眠喚醒後，使用較高控制性策略的組別也較另一組有較高比例報告仍在思考，覺得自己尚未睡著，並低估自己有睡著的時間。 結論：本研究探討控制性不同的再評估策略對主客觀入睡歷程的影響。研究結果支持高控制性策略會造成認知激發狀態，並使受試者在客觀定義入睡喚醒後，仍有較多的思考活動與較少的入睡知覺，同時較低估自己有睡著的時間，顯示入睡前較高的控制性認知活動，的確可能影響受試者的入睡歷程。這支持了先前研究對再評估策略並非單一構念的假設，未來研究再評估策略時，須考慮其次分類才能有全面性的了解。最後，對照過去研究，睡前使用再評估策略的習慣與入睡歷程未有預期的正向關連，可能是與未考慮控制性有關。 / Objective: Reappraisal was found to be effective to decrease negative emotion, thus is considered to be an useful strategy for emotion regulation, because it was (Gross, 1998; 2001). Since negative emotion is associated with sleep disruption, reappraisal is supposed to facilitate sleep-onset. Nevertheless, previous study did not support this point of view (Harvey, 2001; Ree et al., 2005). There was a negative association reported between use of reappraisal and sleep quality in insomnia patients. Researchers have identified different types of reappraisal strategies (McRae et al., 2011) with different levels of controlling cognitive activity. The unexpected association between reappraisal and sleep might be due to the impact of increased level of cognitive activity associated with reappraisal. This study aims to compare the effects of two types of reappraisal strategies, change thought (high cognitive activity) and accept feelings (low cognitive activity), on sleep onset process. Methods: Twenty six participants were recruited for this study, randomized to one of two groups (Acceptance group: N=13, average age=23.6 years; Change group: N=13, average age=24.9 years). Each participant will go through two nights of sleep recording at the sleep lab. The first night was baseline condition; the second night was experimental condition. After the emotion induction, the experimenter instructed the participants to use different reappraisal strategies to regulate their emotion, and then asked them to try to fall sleep in the experimental night. The experimenter woke up participants after 5-min after the start of stage 2 sleep, and asked their subjective experience right before waking up, including sleep perception (sleep or not) and thinking experience. Results: As expected, the Change group had higher controlling cognitive activity and arousal level than the Acceptance group before going to bed. Then, after waking up participants on stable stage 2 sleep, the Change group had higher thinking experience, lower sleep perception and underestimated sleep time than Acceptance group. Conclusions: The findings of this research show that high controlling activity reappraisal could have a negative impact on sleep-onset period than low controlling activity reappraisal. The result supports our hypothesis that controlling cognitive activity can increase pre-sleep arousal level that further increase cognitive activity during sleep-onset period and decrease the perception of sleep.

It is an open question in cognitive emotion regulation research how emotion regulation unfolds over time, and whether the brain regions involved in down-regulation are also recruited during up-regulation of emotions. As a replication and extension of our preceding study, we conducted an fMRI study in young healthy adults on the neural basis of up- and down-regulation of negative and neutral pictures during the immediate stimulation phase as well as after short- and long-term delays (⁠ for immediate and short-term delays, a subset of for long-term delays). For this, we employed three experimental conditions—down-regulation (distance), maintenance (permit), and up-regulation (intensify)—for negative and neutral pictures, and investigated the neural responses during the stimulation and post-stimulation phase as well as during re-exposure after 10 min and after 1 week. We observed the following main results: first, we found greater activation in emotion-generating regions such as the amygdala in the permit vs. distance and the intensify vs. distance comparisons, but not in the intensify vs. permit comparison. Second, we observed greater activation in emotion-regulating regions such as the right inferior parietal and right superior / middle frontal cortex in the distance vs. permit and the distance vs. intensify contrasts, but not the permit vs. intensify contrast. Third, we found that the activation difference between distance and intensify within the amygdala reversed after the regulation period. Fourth, previous emotion regulation did not influence the activation during re-exposure, neither after 10 min nor after 1 week. Taken together, the results provide a partial replication of persistent effects observed in our preceding study, indicate different neural systems for up- and down-regulation, and demonstrate that a broader perspective on emotion regulation can be achieved by simultaneously considering different goals, directions, and strategies of emotion regulation in a single experiment.

大部分情緒調控研究，著重於意圖性(deliberate)調控策略的使用與效果比較(如認知再評估與壓抑)。Bargh, Lee-Chai, Barndollar, Gollwitzer, & Trötschel (2001)透過一系列實驗發現，高階的行為目標，即便在人類覺知外激發，亦能促發人們非意識地產生該目標，並有相關的追求行為。在這樣的理論與實證支持下，Mauss, Cook, & Gross (2007)驗證了情緒調控能以非意識行為進行。Williams, Bargh, Nocera, & Gray (2009)的研究更發現不管是意識或是非意識性地進行情緒調控，都能有效降低心跳改變率。由於目前仍缺乏許多非意識性情緒調控的效果與歷程證據，本研究目的即在藉由事件關聯電位，探討非意識性情緒調控的效果與時間歷程。實驗一透過事件關聯電位，驗證情緒調控能在非意識情況下發生，並發現非意識性壓抑能發生在情緒反應剛產生的300至700毫秒內。實驗二則加入了意識性重新評估與壓抑組參與者，與非意識性重新評估與壓抑組作比較。結果顯示，對參與者而言，(1) 正向情緒為一較容易調控的情緒類別。(2) 使用重新評估調控情緒的效果，仍顯著優於使用壓抑策略。(3) 非意識性情緒調控的結果，也比意識性調控情緒來得較佳。這樣的實驗結果支持了非意識情緒調控的可行性與優點。 / Studies of emotion regulations mostly focused on deliberate control strategies such as cognitive reappraisal and suppression. Bargh and his colleagues conducted a series of experiments and found higher behavioral goals could be primed non-consciously, i.e. outside human awareness (Bargh et al., 2001). Under these assumptions, Mauss, Cook and Gross (2007) verified how emotion regulations be formed through non-conscious behaviors. Williams, Bargh, Nocera, and Gray (2009) also found both conscious and non-conscious reappraisals deduced heart-rate changes. However, it is lack of studies investigating the effects and temporal dynamics of non-conscious emotion regulation. The purpose of this research is to analyze the temporal dynamics and effects of non-conscious emotion regulation processing using event-related potentials. In the first experiment, we verified emotion regulation could be operated under non-conscious way. Also we found non-conscious suppressed goals would be primed and regulated at the beginning of emotional response, i.e., in 300-700ms after the onset of emotion pictures. In the second experiment, we added conscious reappraisal and suppression condition for comparing the non-conscious and conscious regulated effects and time processes. The results showed (1) It was easy for participants to regulate positive emotion. (2) The emotion regulation effect was better with reappraisal strategy than with suppression. (3) Non-conscious emotion regulation would result in better regulated outcomes than conscious emotion regulation. These results supported the practicability and advantages of non-conscious emotion regulation.

過去研究顯示負向情緒會干擾夜間睡眠，預期可有效降低負向情緒的情緒調節策略應有助於睡眠，然而，認知再評估策略對睡眠的影響卻未有一致的研究結果，此可能受限於過去研究多以問卷測量認知再評估策略的使用偏好，卻未測量個體使用策略的能力，亦即認知再評估策略的調節效果。本研究透過實驗室典範測量認知再評估能力，主要探討個體使用認知再評估策略的能力是否會影響個體於夜間情緒調節的效果，以及再評估策略於睡前之適用性。本研究受試者共24位，包含11名男性與13名女性，平均年齡為22歲。受試者皆依序經歷引發和調節負向情緒的實驗情境與中性情境兩個夜晚，並以主觀問卷與客觀生理反應測量受試者使用認知再評估策略調節情緒的表現，及對其後續睡眠的影響，在兩晚作業結束後，受試者會回到實驗室進行認知再評估能力測量作業。研究結果發現，認知再評估能力佳者於實驗晚的情緒調節表現較佳，在能力指標中，正負向與憤怒感調節佳者，其睡前生理激發度增加量較低、入睡前高頻腦波相對功率較低，且較不會高估入睡耗時；此外，運用再評估策略會增加較高情緒控制感者，入睡後高頻腦波相對功率較低，且實驗晚所增加的入睡耗時較低。整體來說，負向情緒會干擾後續睡眠，於正負向指標上調節能力佳者較可減少其主觀失眠困擾度，且使用再評估策略後有較高情緒控制感者，較可彈性的運用再評估策略。 / Negative emotion has been showed to interfere with sleep, therefore effective emotion regulation to reduce negative emotion prior to sleep could be beneficial for sleep. Cognitive reappraisal is generally considered to be an effective and adaptive emotion-regulation strategy, but previous studies had inconsistent findings about the impact of reappraisal on sleep. A study has even found that insomnia patients had a higher frequency to use reappraisal in comparison to good sleepers. However, previous studies used self-report measure of an individual's tendency to use reappraisal. It has been shown that the frequency of using reappraisal did not correlate with the ability to use reappraisal as measured by reduction of stress reactivity after standard laboratory challenge. The present study examined the hypothesis that the impact of pre-sleep reappraisal on sleep onset process depends on individual's cognitive reappraisal ability (CRA). Twenty-four normal sleepers were recruited (male:11, female:13, average age: 22 years). Participants came to sleep laboratory for two experimental nights and one daytime reappraisal ability evaluation. For the two experimental nights, participants did a cognitive task and got two different feedbacks for the two conditions: either a neutral feedback (baseline condition night) or a negative feedback (experimental condition night). They were instructed to use cognitive reappraisal strategy to reduce negative emotion after getting negative feedback. The change of subjective emotion ratings and physiological reaction were measured during the presleep task. Polysomnographic recording and subjective ratings of sleep onset experience was conducted for the sleep onset process analysis. During the daytime session, the ability of the participants to use reappraisal was measured with physiological reactivity to a standard laboratory challenge with anger-inducing films. The results showed that, at experimental night, participants with high CRA in reducing emotion valence exhibited better emotion regulation outcomes, less presleep somatic arousal increments, lower beta power before falling asleep, and less overestimation of their sleep onset latency (SOL). Besides, participants with high CRA in reducing dominance of emotion exhibited shorter emotion regulation time, lower beta power after falling asleep, and lesser SOL increments. This finding is consistent with the hypothesis that reappraisal ability would determined whether cognitive reappraisal strategy is adaptive for presleep emotion regulation; those individuals with better CRA in reducing dominance of emotion might have more flexibility in applying reappraisal strategy.
