The up- and down-regulation of amusement: experiential, behavioral, and autonomic consequences

Effect of laughter exercise versus 0.1% sodium hyaluronic acid on ocular surface discomfort in dry eye disease: non-inferiority randomised controlled trial

OBJECTIVE

To assess efficacy and safety of laughter exercise in patients with symptomatic dry eye disease.

DESIGN

Non-inferiority randomised controlled trial.

SETTING

Recruitment was from clinics and community and the trial took place at Zhongshan Ophthalmic Center, Sun Yat-sen University, the largest ophthalmic centre in China, between 18 June 2020 to 8 January 2021.

PARTICIPANTS

People with symptomatic dry eye disease aged 18-45 years with ocular surface disease index scores ranging from 18 to 80 and tear film break-up time of eight seconds or less.

INTERVENTIONS

Participants were randomised 1:1 to receive laughter exercise or artificial tears (0.1% sodium hyaluronic acid eyedrop, control group) four times daily for eight weeks. The laughter exercise group viewed an instructional video and participants were requested to vocalise the phrases "Hee hee hee, hah hah hah, cheese cheese cheese, cheek cheek cheek, hah hah hah hah hah hah" 30 times per five minute session. Investigators assessing study outcomes were masked to group assignment but participants were unmasked for practical reasons.

MAIN OUTCOME MEASURES

The primary outcome was the mean change in the ocular surface disease index (0-100, higher scores indicating worse ocular surface discomfort) from baseline to eight weeks in the per protocol population. The non-inferiority margin was 6 points of this index score. Main secondary outcomes included the proportion of patients with a decrease from baseline in ocular surface disease index score of at least 10 points and changes in dry eye disease signs, for example, non-invasive tear break up time at eight weeks.

RESULTS

299 participants (mean age 28.9 years; 74% female) were randomly assigned to receive laughter exercise (n=149) or 0.1% sodium hyaluronic acid (n=150). 283 (95%) completed the trial. The mean change in ocular surface disease index score at eight weeks was -10.5 points (95% confidence interval (CI) -13.1 to -7.82) in the laughter exercise group and -8.83 (-11.7 to -6.02) in the control group. The upper boundary of the CI for difference in change between groups was lower than the non-inferiority margin (mean difference -1.45 points (95% CI -5.08 to 2.19); P=0.43), supporting non-inferiority. Among secondary outcomes, the laughter exercise was better in improving non-invasive tear break up time (mean difference 2.30 seconds (95% CI 1.30 to 3.30), P<0.001); other secondary outcomes showed no significant difference. No adverse events were noted in either study group.

CONCLUSIONS

The laughter exercise was non-inferior to 0.1% sodium hyaluronic acid in relieving subjective symptoms in patients with dry eye disease with limited corneal staining over eight weeks intervention.

The effect of emotion regulation on the emotional modulation of pain and nociceptive flexion reflex

ABSTRACT

Positive emotions inhibit pain, whereas negative emotions facilitate pain. Thus, many psychosocial interventions capitalize on this emotion-pain relationship to improve patients' abilities to regulate emotion (ie, reduce negative emotion, increase positive emotion), influence nociception, and manage pain. This study extended the existing literature to examine whether emotion regulation procedures could influence emotional modulation of the nociceptive flexion reflex (NFR), a marker of spinal nociception. To elicit emotion, 2 blocks of pleasant, neutral, and unpleasant pictures were presented. In block 1, participants were asked to passively view pictures during which painful electric stimulations were delivered to evoke pain and the NFR. Valence, arousal, corrugator electromyogram, and skin conductance response were used to measure emotional responses to pictures. To manipulate emotion regulation, participants were randomized to either suppress (downregulate) or enhance (upregulate) their emotion during block 2 (other procedures same as block 1). Instructions to suppress decreased subjective and physiological responding to emotional pictures, reduced emotional modulation of pain, and generally decreased NFR magnitude (regardless of picture content). Instructions to enhance emotion increased subjective responding to emotional pictures but did not alter physiological responding to pictures or emotional modulation of pain/NFR in predictable ways. Results imply that downregulation/suppression of negative emotions may work best to reduce pain facilitation. Furthermore, this study contributes to the existing literature that shows that pain and pain signaling is tightly coupled with emotional states and that emotion regulation can impact pain perception.

Applying a synergistic mindsets intervention to an esports context

Affective responses during stressful, high-stakes situations can play an important role in shaping performance. For example, feeling shaky and nervous at a job interview can undermine performance, whereas feeling excited during that same interview can optimize performance. Thus, affect regulation-the way people influence their affective responses-might play a key role in determining high-stakes outcomes. To test this idea, we adapted a synergistic mindsets intervention (SMI) (Yeager et al. 2022 Nature 607, 512-520 (doi:10.1038/s41586-022-04907-7)) to a high-stakes esports context. Our approach was motivated by the idea that (i) mindsets both about situations and one's stress responses to situations can be shaped to help optimize stress responses, and (ii) challenge versus threat stress responses will be associated with improved outcomes. After a baseline performance task, we randomly assigned gamers (n = 300) either to SMI or a control condition in which they learned brain facts. After two weeks of daily gaming, gamers competed in a cash-prize tournament. We measured affective experiences before the matches and cardiovascular responses before and throughout the matches. Contrary to predictions, gamers did not experience negative affect (including feeling stressed), thus limiting the capacity for the intervention to regulate physiological responses and optimize performance. Compared with the control participants, synergistic mindsets participants did not show greater challenge responses or improved performance outcomes. Though our adaptation of Yeager et al.'s SMI did not optimize esports performance, our findings point to important considerations regarding the suitability of an intervention such as this to different performance contexts of varying degrees of stressfulness.

If it Ain't Broke, Don't Fix it: Positive Versus Negative Emotion Regulation in Daily Life and Depressive Symptoms

BACKGROUND

Despite the importance of positive emotions for affective psychopathology, prior research primarily focused on negative emotion regulation. To address this gap, this ecological momentary assessment study compared a broad set of emotion regulation strategies in the context of positive versus negative emotions regarding their effectiveness and associations with depressive symptoms.

METHODS

We analyzed data from 1066 participants who were notified five times daily for seven consecutive days to complete a smartphone survey assessing their predominant emotions, strategies to regulate them, and subsequent emotional outcomes.

RESULTS

Findings show that the effectiveness of most regulation strategies depended on whether the emotional context was positive or negative. While acceptance and savoring predicted improved emotional outcomes across emotional contexts, reappraisal and problem-solving were associated with deteriorated emotional outcomes and increased depressive symptoms when regulating positive but not negative emotions.

LIMITATIONS

Future studies should replicate our findings in demographically and culturally diverse clinical samples to improve generalizability.

CONCLUSION

These results emphasize that strategies effective for regulating negative emotions may be less helpful in the context of positive emotions. Thus, context-specific interventions may be a promising approach to improve the treatment of affective disorders.

Quantitative versus qualitative emotion regulation goals: Differential effects on emotional responses

Emotion regulation (ER) involves both a goal (e.g., to feel less emotion) and a strategy (e.g., reappraisal). To clarify the impact of ER goals on emotional responding, we conducted a within-participant study (N = 156) in which we held the strategy constant (reappraisal) to isolate the impact of regulation goals. We compared the impact of a quantitative goal (changing emotion quantity/intensity) with that of a qualitative goal (changing emotion quality/type) on emotional responses to negative and positive pictures. We manipulated ER goals by cuing participants to continue viewing the picture (unregulated/no ER goal) or to reappraise it to decrease its predominant affective impact (quantitative goal) or increase its opposite-valence impact (qualitative goal). We assessed emotional responses through self-reported feelings and facial expressions (corrugator supercilii and zygomaticus major electromyography). Our findings suggest that the type of regulation goal has a differential effect on emotional responses, with qualitative goals being more effective in modulating both negative and positive emotions. For negative stimuli, attempts to use a quantitative goal decreased negative but not positive emotional responses (uncoupled negative deactivation). Conversely, attempts to use a qualitative goal decreased negative and increased positive emotional responses (reciprocal positive activation). For positive stimuli, the quantitative goal generated uncoupled positive deactivation, while the qualitative goal produced reciprocal negative activation. Results highlight the importance of considering specific regulation goals in shaping emotional responses. Future research in the field of ER may benefit from identifying and manipulating different goals and strategies to understand how to effectively regulate emotions.

Fitting Bayesian Stochastic Differential Equation Models with Mixed Effects through a Filtering Approach

Recent advances in technology contribute to a fast-growing number of studies utilizing intensive longitudinal data, and call for more flexible methods to address the demands that come with them. One issue that arises from collecting longitudinal data from multiple units in time is nested data, where the variability observed in such data is a mixture of within-unit changes and between-unit differences. This article aims to provide a model-fitting approach that simultaneously models the within-unit changes with differential equation models and accounts for between-unit differences with mixed effects. This approach combines a variant of the Kalman filter, the continuous-discrete extended Kalman filter (CDEKF), and the Markov chain Monte Carlo method often employed in the Bayesian framework through the platform Stan. At the same time, it utilizes Stan's functionality of numerical solvers for the implementation of CDEKF. For an empirical illustration, we applied this method in the context of differential equation models to an empirical dataset to explore the physiological dynamics and co-regulation between couples.

The EEG microstate representation of discrete emotions

Understanding how human emotions are represented in our brain is a central question in the field of affective neuroscience. While previous studies have mainly adopted a modular and static perspective on the neural representation of emotions, emerging research suggests that emotions may rely on a distributed and dynamic representation. The present study aimed to explore the EEG microstate representations for nine discrete emotions (Anger, Disgust, Fear, Sadness, Neutral, Amusement, Inspiration, Joy and Tenderness). Seventy-eight participants were recruited to watch emotion eliciting videos with their EEGs recorded. Multivariate analysis revealed that different emotions had distinct EEG microstate features. By using the EEG microstate features in the Neutral condition as the reference, the coverage of C, duration of C and occurrence of B were found to be the top-contributing microstate features for the discrete positive and negative emotions. The emotions of Disgust, Fear and Joy were found to be most effectively represented by EEG microstate. The present study provided the first piece of evidence of EEG microstate representation for discrete emotions, highlighting a whole-brain, dynamical representation of human emotions.

Emotion Regulation Scale and Mindfulness Scale in School Aged Children: Construction and Validation of French Versions

Few measuring scales seem to evaluate Mindfulness and emotion regulation in school aged children. This article aims to present four studies describing the construction and validation of two French measuring scales for children: French Emotion Regulation Scale for Children (FERS-C) and Mindfulness Scale for Children French version (MSC-F). We discuss the elaboration and choice of the items for each measure, examine their phrasing and comprehensibility from the children's standpoint. The main sample consisted of 421 non-clinical, 6 to 12 years old children, who consented to fill out the measuring scales in order to test the factor structure. Additionally, we assessed and confirmed temporal stability and determined convergent validity. Results support that both scales appear to be reliable emotion regulation and mindfulness measures for school aged children. Results also reveal a relevant factor structure for both measures. The results of these studies support that the two scales are appropriate and useful measures of mindfulness and emotion regulation capacities for school aged children. In conclusion, we call for further research to improve and develop measures assessing child mindfulness skills in both clinical and research contexts.

Experiential, expressive, and physiological effects of positive and negative emotion regulation goals while reappraising amusing stimuli

We examined whether positive and negative emotion regulation (ER) goals while cognitively reappraising amusing stimuli differentially engage positive (PA) and negative affect (NA) systems. Forty-eight women watched 20-30s amusing film clips. They were instructed to either respond naturally (no ER goal) or emphasize the film clips' positive (positive ER goal) or negative (negative ER goal) aspects in their interpretation. We measured PA and NA system activity on experiential, expressive, and physiological response channels through self-reported amusement and disgust, electromyography of zygomaticus major and corrugator supercilii, and autonomic nervous system reactivity from respiratory sinus arrhythmia (RSA) and pre-ejection period (PEP). Natural viewing (no ER goal) of amusing clips increased self-reported amusement (and to a lesser degree disgust), zygomaticus reactivity, and RSA. Compared to no and negative ER goals, reappraising the amusing clips with a positive ER goal decreased corrugator reactivity, decreasing negative emotional expression. Compared to no and positive ER goals, reappraising the amusing clips with a negative ER goal decreased self-reported amusement and zygomaticus reactivity and increased self-reported disgust and corrugator reactivity, decreasing positive and increasing negative emotional experience and expression. We conclude that positive and negative ER goals while reappraising amusing stimuli differentially engaged PA and NA systems: The positive ER goal engaged withdrawal of the expressive NA system, whereas the negative ER goal engaged reciprocal NA-PA system activation on experiential and expressive response channels.

Autonomic Nervous System Activity During Positive Emotions: A Meta-Analytic Review

Autonomic nervous system (ANS) activity is a fundamental component of emotional responding. It is not clear, however, whether positive emotional states are associated with differential ANS reactivity. To address this issue, we conducted a meta-analytic review of 120 articles (686 effect sizes, total N = 6,546), measuring ANS activity during 11 elicited positive emotions, namely amusement, attachment love, awe, contentment, craving, excitement, gratitude, joy, nurturant love, pride, and sexual desire. We identified a widely dispersed collection of studies. Univariate results indicated that positive emotions produce no or weak and highly variable increases in ANS reactivity. However, the limitations of work to date – which we discuss – mean that our conclusions should be treated as empirically grounded hypotheses that future research should validate.

Predictors of Severity and Change in Emotion Dysregulation among Children and Adolescents with ASD

OBJECTIVE

Emotion dysregulation problems are prevalent and disruptive for many with autism spectrum disorder (ASD). This study compared severity and perceived change in emotion dysregulation in youth with and without ASD and probed correlates of emotion dysregulation (including possible two-way interactions) among youth with ASD.

METHOD

Participants were drawn from two large online samples (mean age = 12; range: 6-17) with (N = 1323) and without (N = 921) ASD. The study used the Emotion Dysregulation Inventory (EDI), a parent-report measure designed for youth with ASD. The EDI asks parents about current severity and perceived change (i.e. how current severity compares to lifetime severity) in emotion dysregulation, and includes two factors: Reactivity (rapidly escalating, intense negative affect) and Dysphoria (poorly upregulated positive affect, general unease).

RESULTS

Results indicated that youth with ASD had greater Reactivity severity and also greater positive change in Reactivity than non-ASD peers. Furthermore, differences between youth with and without ASD in the relationship between Reactivity and Dysphoria suggest a distinct profile of emotion dysregulation in ASD. Within the ASD sample, age and severity of stereotyped behavior predicted Reactivity and Dysphoria severity and Reactivity change. Female gender, lower parent education, and fluent verbal ability were additional predictors of increased Reactivity severity, while intellectual disability predicted lower Dysphoria severity.

CONCLUSIONS

This study provides new insight into predictors of emotion dysregulation in youth with ASD and represents a first step toward identifying which children with ASD may be most vulnerable to severe emotion dysregulation problems.

Validating the Self-assessed Wisdom Scale (SAWS) in an Iranian Sample: Psychometric and Developmental Findings

This study aimed to investigate the validity and factor structure of the Self-Assessed Wisdom Scale (SAWS; Webster in J Adult Dev 10:13-22, 2003) in an Iranian population. Participants (235 male, 340 female) were recruited in Tehran, Iran and ranged in age from 17 to 88 years. Cronbach alpha's for the subscales ranged from .63 to .81, and their inter-correlations ranged from .42 to .53. Exploratory factor analysis extracted 5 factors that were similar with the original structure. Confirmatory factor analysis supported 5-factor model of the SAWS. The SAWS's total and subscale scores positively correlated with two other measures of wisdom (indicating convergent validity). The SAWS correlated weakly with age. Women scored higher in the SAWS subscales of emotional regulation, reminiscence/reflectiveness, and humor, which accounted for a significant gender difference in total wisdom. Although the age differences are consistent with prior research, the gender differences are relatively novel. Overall, results indicate that the SAWS has excellent psychometric properties and can be used in cross-cultural work.

Interplay of occupational stress, sense of humor, and health status among nurses working at hospitals in Ahvaz

Sense of humor constitutes a part of everyday life and work and an indispensable part of healthcare. However, the relationship between sense of humor and nursing occupational health and stress is yet to be studied in Iran. This study aimed to analyze the interplay of demographic factors, occupational stress, sense of humor, and health status of nurses working at the hospitals affiliated with the Ahvaz Jundishapur University of Medical Sciences, Iran. In this descriptive-analytical study, the statistical population consisted of 203 nurses. Occupational stress was assessed using the Iranian version of the Effort-Reward-Imbalance (ERI) Questionnaire. The Sense of Humor Questionnaire (SHQ) and the Iranian version of the 12-item General Health Questionnaire (GHQ-12) were employed to assess the sense of humor and physio-psychological health, respectively. Data collected were analyzed using the Statistical Package for the Social Sciences (SPSS) software. 81% (n=164) of the participants had an “external effort” (E) and “reward” (R) ratio greater than 1, indicating very high occupational stress. 39% (n=79) nurses with high occupational stress displayed their commitment to the workplace. Approximately 42% (n=85) of nurses were suffering from health problems. The mean humor score of participants was 2.90±0.41. Major life events over the past 3 months (p<0.01), weekly working hours (p<0.01), high occupational stress (p<0.01), and sense of humor (p<0.01) were determined to be significant predictors of nurses' health problems. Decision-makers are recommended to reduce nursing working hours through work shift management in order to maintain nurses' health status and reduce their occupational stress. In addition, hospital directors should promote a sense of humor in hospital environments with the help of culture-building practices, comedy books, music CDs, and training courses.

Savoring the present: The reciprocal influence between positive emotions and positive emotion regulation in everyday life

A growing body of research has investigated the regulation of negative emotions in ecological settings, but little is known about the mechanisms underlying positive emotion regulation in everyday life. Although some evidence suggests that adopting positive strategies is beneficial for emotional well-being, the literature is inconsistent about the effects of positive emotions on subsequent regulatory processes. In the present study, we adopted a two-week ecological momentary assessment to explore the association between positive emotions and positive emotion regulation in daily life. According to our results, the less individuals felt positive emotions at one point, the more they tended to enhance their use of positive strategies from this time to the next, which in turn resulted in subsequent higher levels of positive emotions. This prototype of positive regulation can be seen as a highly adaptive mechanism that makes it possible to compensate for a lack of positive emotions by enhancing the deployment of positive strategies. The theoretical and clinical implications of these findings are discussed.

The autonomic nervous system in its natural environment: Immersion in nature is associated with changes in heart rate and heart rate variability

Stress Recovery Theory (SRT) suggests that time spent in nature reduces stress. While many studies have examined changes in stress physiology after exposure to nature imagery, nature virtual reality, or nature walks, this study is the first to examine changes in heart rate (HR) and vagally mediated HR variability, as assessed by Respiratory Sinus Arrythmia (RSA), after a longer duration of nature exposure. Consistent with SRT, we hypothesized that immersion in nature would promote stress recovery, as indexed by an increase in RSA and a decrease in HR. We also predicted that exposure to nature would improve self-reported mood. We used a within-subjects design (N = 67) to assess changes in peripheral physiology before, during, and after a 5-day nature trip. Results demonstrated a significant decrease in RSA and a significant increase in HR during the trip compared to before or after the trip, suggesting that immersion in nature is associated with a shift toward parasympathetic withdrawal and possible sympathetic activation. These results were contrary to our hypotheses and may suggest increased attentional intake or presence of emotions associated with an increase in sympathetic activation. We also found an improvement in self-reported measures of mood during the trip compared to before or after the trip, confirming our hypotheses and replicating previous research. Implications of this study are discussed in the context of SRT.

Psychophysiological Effects of Downregulating Negative Emotions: Insights From a Meta-Analysis of Healthy Adults

Assessing psychophysiological responses of emotion regulation is a cost-efficient way to quantify emotion regulation and to complement subjective report that may be biased. Previous studies have revealed inconsistent results complicating a sound interpretation of these findings. In the present study, we summarized the existing literature through a systematic search of articles. Meta-analyses were used to evaluate effect sizes of instructed downregulation strategies on common autonomic (electrodermal, respiratory, cardiovascular, and pupillometric) and electromyographic (corrugator activity, emotion-modulated startle) measures. Moderator analyses were conducted, with moderators including study design, emotion induction, control instruction and trial duration. We identified k = 78 studies each contributing multiple sub-samples and performed 23 meta-analyses for combinations of emotion regulation strategy and psychophysiological measure. Overall, results showed that effects of reappraisal and suppression on autonomic measures were highly inconsistent across studies with rather small mean effect sizes. Electromyography (startle and corrugator activity) showed medium effect sizes that were consistent across studies. Our findings highlight the diversity as well as the low level of standardization and comparability of research in this area. Significant moderation of effects by study design, trial duration, and control condition emphasizes the need for better standardization of methods. In addition, the small mean effect sizes resulting from our analyses on autonomic measures should be interpreted with caution. Findings corroborate the importance of multi-channel approaches.

Relationship between resilience and insomnia among the middle-aged and elderly: mediating role of maladaptive emotion regulation strategies

This study aimed to investigate the relationships between cognitive emotion regulation (CER) strategies, resilience, and insomnia and the underlying mechanism that explains the relationships. Six hundred and fifty-three middle-aged and old people recruited from community service centers in Henan province completed questionnaires related to CER strategies, resilience, and insomnia. Results showed refocus on planning and positive reappraisal negatively predicted insomnia, and catastrophising, rumination and self-blame positively predicted insomnia. Moreover, maladaptive emotion regulation strategies (especially catastrophising) mediated the relationship between resilience and insomnia. The findings suggest the middle-aged and elderly with insomnia tended to employ maladaptive emotion regulation strategies and had lower resilience. Maladaptive emotion regulation strategies buffered the positive effect of resilience on sleep.

Neural correlates of up-regulating positive emotions in fMRI and their link to affect in daily life

Emotion regulation is typically used to down-regulate negative or up-regulate positive emotions. While there is considerable evidence for the neural correlates of the former, less is known about the neural correlates of the latter—and how they are associated with emotion regulation and affect in daily life. Functional magnetic resonance imaging (fMRI) data were acquired from 63 healthy young participants (22 ± 1.6 years, 30 female), while they up-regulated their emotions to positive and neutral images or passively watched them. The same participants’ daily affect and emotion regulation behavior was measured using experience sampling over 10 days. Focusing on the ventral striatum (VS), previously associated with positive affective processing, we found increased activation during the up-regulation to both positive and neutral images. VS activation for the former positively correlated with between- and within-person differences in self-reported affective valence during fMRI but was not significantly associated with up-regulation in daily life. However, participants with lower daily affect showed a stronger association between changes in affect and activation in emotion-related (medial frontal and subcortical) regions—including the VS. These results support the involvement of the VS in up-regulating positive emotions and suggest a neurobehavioral link between emotion-related brain activation and daily affect.

Age-Related Differences in the Late Positive Potential during Emotion Regulation between Adolescents and Adults

The late positive potential (LPP) has been well documented in predicting the effect of emotion regulation in previous developmental literature. However, few studies have examined age-related changes in emotion regulation from adolescence to adulthood using this biomarker. To test this, Reactivity and Regulation-Image Task was used to test 18 young adolescents and 22 adults to examine the modulation of LPP during emotion regulation. Results revealed that (a) on the behavioral level, adults reported higher intensity of emotional experience than adolescents when they were asked to use up-regulation. Down-regulation showed no age effect for self-reported rating; (b) adolescents showed higher amplitudes of LPP than adults when using different regulatory strategies in all windows; (c) In late time window, regulation effect was larger when using up-regulation strategy than down-regulation strategy for adolescents, while the difference between the two strategies was negligible for adults. (d) In early time window, reactivity effect was larger in negative conditions than in positive conditions for adolescents, while the difference between the two conditions was again negligible for adults. Differences in the amplitudes and time courses of LPP during emotion regulation between adolescents and adults suggested that age-related changes in emotion regulation may occur during adolescence.

Cognitive-affective strategies and cortisol stress reactivity in children and adolescents: Normative development and effects of early life stress

This study examined cognitive-affective strategies as predictors of hypothalamic-pituitary-adrenal (HPA) axis responses to a social-evaluative stressor in adolescence as compared to late childhood as a function of early life experiences. Participants included 159 children (9-10 years) and adolescents (15-16 years) divided into two groups based on early care experiences: non-adopted youth raised in their birth families (n = 81) and post-institutionalized youth internationally adopted from orphanage care (n = 78). Youth completed a version of the Trier Social Stress Test modified for use with children and reported on their trait emotion regulation and coping strategies. Children reported more use of suppression and disengagement than adolescents, while adolescents reported more engagement coping strategies. Non-adopted and post-institutionalized youth did not differ in reported strategies. Cognitive reappraisal predicted higher cortisol reactivity in non-adopted children and adolescents, and was not associated with reactivity in the post-institutionalized group. This study has implications for efforts aimed at promoting self-regulation and adaptive stress responses during the transition to adolescence for both typically developing children and children who experienced adverse early care.

Cognitive Reappraisal in Children: Neuropsychological Evidence of Up-Regulating Positive Emotion From an ERP Study

Emotion regulation is a critical mechanism in the socio-emotional development of children. Previous studies revealed that children use cognitive reappraisal to downregulate negative emotions. Moreover, the amplitude of late positive potential (LPP) shows a more obvious reduction following neutral interpretations than following negative interpretations. However, whether children can use cognitive reappraisal to regulate positive emotions remains unclear. In the present study, 46 8- to 12-year-old children were asked to reappraise the meaning of pleasant pictures. Electroencephalography (EEG) data were collected during the task. As predicted, LPP amplitudes increased more following reappraisal condition than following pleasant condition. The analysis of spatial-temporal shifting patterns showed that the effect occurred in the earlier window for the posterior region. As time progressed, this effect evidenced a trend from posterior region to the central and anterior regions, especially for the younger children. Furthermore, the greater brain activations occurred in left hemisphere when children upregulated positive emotions which partially supported previous research suggesting that increasing positive emotion engaged primarily left-lateralized prefrontal regions. Taken together, the findings suggest that children can use cognitive reappraisal to upregulate positive emotions.

Humor Affects Fairness Considerations in the Gain and Loss Contexts

Human decision-making behaviors in social contexts are largely driven by fairness considerations. The dual-process model suggests that in addition to cognitive processes, emotion contributes to economic decision-making. Although humor, as an effective emotional regulation strategy to induce positive emotion, may influence an individual's emotional state and decision-making behavior, previous studies have not examined how humor modulates fairness-related responses in the gain and loss contexts simultaneously. This study uses the Ultimatum Game (UG) in gain and loss contexts to explore this issue. The results show, in the gain context, viewing humorous pictures compared to humorless pictures increased acceptance rates and this effect was moderated by the offer size. However, we did not find the same effect in the loss context. These findings indicate that humor's affection for fairness considerations may depend on the context and provide insight into the finite power of humor in human sociality, cooperation and norm compliance.

A standardised database of Chinese emotional film clips

Film clips are widely used in emotion research due to their relatively high ecological validity. Although researchers have established various film clip sets for different cultures, the few that exist related to Chinese culture do not adequately address positive emotions. The main purposes of the present study were to establish a standardised database of Chinese emotional film clips that could elicit more categories of reported positive emotions compared to the existing databases and to expand the available film clips that can be used as neutral materials. Two experiments were conducted to construct the database. In experiment 1, 111 film clips were selected from more than one thousand Chinese movies for preliminary screening. After 315 participants viewed and evaluated these film clips, 39 excerpts were selected for further validation. In experiment 2, 147 participants watched and rated these 39 film clips, as well as another 8 excerpts chosen from the existing databases, to compare their validity. Eventually, 22 film excerpts that successfully evoked three positive emotions (joy, amusement, and tenderness), four negative emotions (moral disgust, anger, fear, and sadness), and neutrality formed the standardised database of Chinese emotional film clips.

Emotion regulation in autism spectrum disorder: Where we are and where we need to go

Emotion dysregulation is a common issue experienced by individuals with autism spectrum disorder (ASD) and has been associated with a wide range of negative mental and physical health outcomes. This commentary highlights the role emotion dysregulation plays in ASD by first considering the literature on emotion regulation (ER) in the general population and then summarizing the ER research in ASD. Based on the evaluation of previous research findings, we conclude that individuals with ASD have more ER difficulties and consistently self-report or demonstrate a less adaptive pattern of ER strategy use. In addition, the higher prevalence of internalizing and externalizing issues seen in ASD are associated with the greater habitual use of some ER strategies and less habitual use of others. Conceptual and methodological limitations are discussed, including the use of coping measures and single-method approaches, and ASD gender distribution. We propose a set of new directions for investigating ER in ASD, incorporating knowledge from other literatures on the role of flexibility in healthy adaptation, overlaps between flexibility and executive function deficits, the adaptive value of up-regulation of positive emotions, and the importance of emotional self-awareness. Increasing our capacity for identifying the mechanisms underlying co-morbid affective disorders can ultimately inform the design of effective interventions to maximize the wellbeing of individuals with ASD.

LAY SUMMARY

Research has shown that people diagnosed with autism tend to have difficulties with regulating their own emotions. This commentary article summarizes the main information from emotion regulation research conducted both in autism and in other populations. We make suggestions on how we can improve emotion regulation research in autism, with the ultimate goal being to use the learning gained from research to design effective interventions that can improve the wellbeing of people with autism.

Spontaneous response to and expressive regulation of mirth elicited by humorous cartoons in younger and older adults

Many studies have examined the effect of aging on the ability to regulate negative emotions but less is known about the way the elderly people control their positive affects. Thirty-eight younger and 38 older adults were compared on their affective, expressive, physiological, and behavioral spontaneous responses to and in expressive regulation of mirth elicited by humorous cartoons. Compared to younger adults, older adults were equally amused and aroused but showed lower expressivity in their spontaneous reaction. They were similarly successful in implementing expressive regulation but they had lower physiological activation under amplification condition and more gaze avoidance from the key areas of the cartoons under suppression condition. This indicates that in older, amplification skills are disjointed from the physiological responses and suppression skills seem supplanted by a less costly strategy of attention redeployment. This also suggests that older adults' behavior is not driven by a greater preference for positive information.

Self-regulation in entrepreneurs

Psychological processes (e.g., cognition, motivation, emotions) have emerged as key to understanding entrepreneurial actions and success. Currently, we do not know enough about specific entrepreneurial psychological processes and particularly lack knowledge about their cumulative or interactive effects. Self-regulation offers some promise in understanding these issues. However, self-regulation in entrepreneurship has not been fully explored, which limits our understanding. We address this by introducing an integrated model of episodic self-regulation (the A-CEM-A model) to map the reciprocal regulatory effects of action, cognition, emotion, and motivation in entrepreneurship research and isolate a series of propositions stemming from the model. We further explore the resource implications of the A-CEM-A model for entrepreneurs managing several self-regulatory processes simultaneously. The A-CEM-A model offers a novel and unique insight into entrepreneurial action and psychological processes, and presents a roadmap for future researchers interested in adopting an episodic process perspective in entrepreneurship research.

Humor Use Moderates the Relation of Stressful Life Events With Psychological Distress

Three studies examined humor and adjustment to stressful events. In Study 1, patients with fibromyalgia syndrome ( N = 22) reported on mental and physical adjustment, social interaction, and reappraisal of their illness. Dispositional humor was associated with reduced distress and fewer physical symptoms. Study 2 ( N = 109) examined undergraduates’ reports of stressful events. Dispositional, self-enhancing, affiliative, and self-defeating humor showed direct effects on distress, which were mediated by social interaction and reappraisal. Moreover, dispositional and aggressive humor showed stress-buffering effects. Study 3 ( N = 105) examined undergraduates’ adjustment to the September 11, 2001, attacks at 1 and 3 months postattack. At T1, affiliative humor showed a stress-buffering effect on distress. Social interaction mediated the relation of self-enhancing humor with reduced T1 distress, and mediated relations of aggressive and self-defeating humor with greater distress. Relations of T1 dispositional and self-defeating humor to changes in T2 distress were mediated by reappraisal.

EEG Correlates of Ten Positive Emotions

Compared with the well documented neurophysiological findings on negative emotions, much less is known about positive emotions. In the present study, we explored the EEG correlates of ten different positive emotions (joy, gratitude, serenity, interest, hope, pride, amusement, inspiration, awe, and love). A group of 20 participants were invited to watch 30 short film clips with their EEGs simultaneously recorded. Distinct topographical patterns for different positive emotions were found for the correlation coefficients between the subjective ratings on the ten positive emotions per film clip and the corresponding EEG spectral powers in different frequency bands. Based on the similarities of the participants' ratings on the ten positive emotions, these emotions were further clustered into three representative clusters, as 'encouragement' for awe, gratitude, hope, inspiration, pride, 'playfulness' for amusement, joy, interest, and 'harmony' for love, serenity. Using the EEG spectral powers as features, both the binary classification on the higher and lower ratings on these positive emotions and the binary classification between the three positive emotion clusters, achieved accuracies of approximately 80% and above. To our knowledge, our study provides the first piece of evidence on the EEG correlates of different positive emotions.

Emotion regulation changes the duration of the BOLD response to emotional stimuli

Emotion regulation theories posit that strategies like reappraisal should impact both the intensity and duration of emotional responses. However, research on reappraisal to date has examined almost exclusively its effect on the intensity of responses while failing to examine its effect on the duration of responses. To address this, we used inverse logit functions to estimate the height and duration of hemodynamic responses to negative pictures when individuals with recent life stress were instructed to use reappraisal either to decrease their negative emotion or to increase their positive emotion (relative to unregulated viewing of negative pictures). Several emotion-generative regions such as the amygdala, thalamus and midbrain exhibited decreases in duration of activation, even when controlling for differences in height of activation. In addition, whereas the amygdala exhibited both decreased activation height and duration when participants reappraised to decrease their negative emotion, it only exhibited decreased duration when participants reappraised to increase their positive emotion. These results indicate that emotion regulation alters the temporal dynamics of emotional responding and that models of reappraisal should accommodate whether reappraisal influences the height of activation, duration of activation or both, which may change based on the goal of the reappraisal strategy being used.

Emotion Regulation: A Transdiagnostic Perspective on a New RDoC Domain

It is widely agreed that emotion regulation plays an important role in many psychological disorders. We make the case that emotion regulation is in fact a key transdiagnostic factor, using the Research Domain Criteria (RDoC) as an organizing framework. In particular, we first consider how transdiagnostic and RDoC approaches have extended categorical views. Next, we examine links among emotion generation, emotion regulation, and psychopathology, with particular attention to key emotion regulation stages including identification, strategy selection, implementation, and monitoring. We then propose that emotion regulation be viewed as a sixth domain in the RDoC matrix, and provide a brief overview of how the literature has used the RDoC units of analyses to study emotion regulation. Finally, we highlight opportunities for future research and make recommendations for assessing and treating psychopathology.

Social re-orientation and brain development: An expanded and updated view

•

We expand our adolescent re-orientation model to include other developmental periods.

•

We review neuroimaging literature on social information processing.

•

We combine human and animal based approaches to social behavior.

Social development has been the focus of a great deal of neuroscience based research over the past decade. In this review, we focus on providing a framework for understanding how changes in facets of social development may correspond with changes in brain function. We argue that (1) distinct phases of social behavior emerge based on whether the organizing social force is the mother, peer play, peer integration, or romantic intimacy; (2) each phase is marked by a high degree of affect-driven motivation that elicits a distinct response in subcortical structures; (3) activity generated by these structures interacts with circuits in prefrontal cortex that guide executive functions, and occipital and temporal lobe circuits, which generate specific sensory and perceptual social representations. We propose that the direction, magnitude and duration of interaction among these affective, executive, and perceptual systems may relate to distinct sensitive periods across development that contribute to establishing long-term patterns of brain function and behavior.

Assessing positive emotional states in dogs using heart rate and heart rate variability

Since most animal species have been recognized as sentient beings, emotional state may be a good indicator of welfare in animals. The goal of this study was to manipulate the environment of nine beagle research dogs to highlight physiological responses indicative of different emotional experiences. Stimuli were selected to be a more or a less positive food (meatball or food pellet) or social reward (familiar person or less familiar person). That all the stimuli were positive and of different reward value was confirmed in a runway motivation test. Dogs were tested individually while standing facing a display theatre where the different stimuli could be shown by lifting a shutter. The dogs approached and remained voluntarily in the test system. They were tested in four sessions (of 20s each) for each of the four stimuli. A test session consisted of four presentation phases (1st exposure to stimulus, post exposure, 2nd exposure, and access to reward). Heart rate (HR) and heart rate variability (HRV) responses were recorded during testing in the experimental room and also when lying resting in a quiet familiar room. A new method of 'stitching' short periods of HRV data together was used in the analysis. When testing different stimuli, no significant differences were observed in HR and LF:HF ratio (relative power in low frequency (LF) and the high-frequency (HF) range), implying that the sympathetic tone was activated similarly for all the stimuli and may suggest that dogs were in a state of positive arousal. A decrease of HF was associated with the meatball stimulus compared to the food pellet and the reward phase (interacting with the person or eating the food) was associated with a decrease in HF and RMSSD (root mean square of successive differences of inter-beat intervals) compared to the preceding phase (looking at the person or food). This suggests that parasympathetic deactivation is associated with a more positive emotional state in the dog. A similar reduction in HF and RMSSD was found in the test situation compared to the resting situation. This is congruent with the expected autonomic effects related to postural shift i.e. sympathetic activation and parasympathetic withdrawal, during standing versus lying, but it cannot explain the parasympathetic deactivation in response to the more positive stimuli since the dogs were always standing in the test situation. We discuss the systematic pattern of responses, which support that increased HR and LF:HF ratio are associated with emotional arousal, but add the new proposal that a combined decrease in RMSSD and HF may reflect a more positively valenced emotional state even when an individual is already in a positive psychological state.

Emotion regulation in heavy smokers: experiential, expressive and physiological consequences of cognitive reappraisal

Emotion regulation dysfunctions are assumed to contribute to the development of tobacco addiction and relapses among smokers attempting to quit. To further examine this hypothesis, the present study compared heavy smokers with non-smokers (NS) in a reappraisal task. Specifically, we investigated whether non-deprived smokers (NDS) and deprived smokers (DS) differ from non-smokers in cognitive emotion regulation and whether there is an association between the outcome of emotion regulation and the cigarette craving. Sixty-five participants (23 non-smokers, 22 NDS, and 20 DS) were instructed to down-regulate emotions by reappraising negative or positive pictorial scenarios. Self-ratings of valence, arousal, and cigarette craving as well as facial electromyography and electroencephalograph activities were measured. Ratings, facial electromyography, and electroencephalograph data indicated that both NDS and DS performed comparably to nonsmokers in regulating emotional responses via reappraisal, irrespective of the valence of pictorial stimuli. Interestingly, changes in cigarette craving were positively associated with regulation of emotional arousal irrespective of emotional valence. These results suggest that heavy smokers are capable to regulate emotion via deliberate reappraisal and smokers’ cigarette craving is associated with emotional arousal rather than emotional valence. This study provides preliminary support for the therapeutic use of reappraisal to replace maladaptive emotion-regulation strategies in nicotine addicts.

A new look at social support: a theoretical perspective on thriving through relationships

Close and caring relationships are undeniably linked to health and well-being at all stages in the life span. Yet the specific pathways through which close relationships promote optimal well-being are not well understood. In this article, we present a model of thriving through relationships to provide a theoretical foundation for identifying the specific interpersonal processes that underlie the effects of close relationships on thriving. This model highlights two life contexts through which people may potentially thrive (coping successfully with life's adversities and actively pursuing life opportunities for growth and development), it proposes two relational support functions that are fundamental to the experience of thriving in each life context, and it identifies mediators through which relational support is likely to have long-term effects on thriving. This perspective highlights the need for researchers to take a new look at social support by conceptualizing it as an interpersonal process with a focus on thriving.

Integrating emotion regulation and emotional intelligence traditions: a meta-analysis

Two relatively independent research traditions have developed that address emotion management. The first is the emotion regulation (ER) tradition, which focuses on the processes which permit individuals to influence which emotions they have, when they have them, and how they experience and express these emotions. The second is the emotional intelligence (EI) tradition, which focuses—among other things—on individual differences in ER. To integrate these two traditions, we employed the process model of ER (Gross, 1998b) to review the literature on EI. Two key findings emerged. First, high EI individuals shape their emotions from the earliest possible point in the emotion trajectory and have many strategies at their disposal. Second, high EI individuals regulate their emotions successfully when necessary but they do so flexibly, thereby leaving room for emotions to emerge. We argue that ER and EI traditions stand to benefit substantially from greater integration.
