Culture shapes electrocortical responses during emotion suppression

The paradox of social avoidance and the yearning for understanding: Elevated interbrain synchrony among socially avoidant individuals during expression of negative emotions

Social avoidance refers to the tendency to be alone and non-participating to social interactions, which is considered to hamper health interpersonal relationship. However, the neural underpinnings of social and emotional interactions among social avoidant individuals have not been fully studied. In the present study, we used EEG hyperscanning technology to investigate the brain activity and its synchronization of 25 socially avoidant dyads and 28 comparison dyads during an emotional communication task. The emotional communication task consisted of the emotional processing stage and emotional interaction stage. Event-related potentials (ERPs) of the senders during the emotional processing stage and the interbrain synchrony (IBS) of the dyads during the emotional interaction stage were analyzed. Results showed that (1) socially avoidant group showed higher beta, theta and gamma IBS in the negative condition than in the positive and neutral condition; (2) in positive condition, the N1 and LPP amplitudes during the emotional processing stage of socially avoidant individuals were negatively correlated with the IBS within dyads during the emotional communication stage. The findings suggest that the dysfunctional emotional interaction of social avoidant individuals may be attributed to the negative impact of emotional stimuli processing during emotional communication.

Effects of congruent emotional contexts during encoding on recognition: An ERPs study

Past research showed that emotional contexts can impair recognition memory for the target item. Given that item-context congruity may enhance recognition memory, the present study aims to examine the effect of the congruent emotional encoding contexts on recognition memory. Participants studied congruent word-picture pairs (e.g., the word "cow" - a picture describing a cow) and incongruent word-picture pairs (e.g., the word "cow" - a picture describing a goat) and, subsequently, were asked to report the nature of the picture (emotional or neutral). Behavioral results revealed that emotional contexts impaired source but not item recognition, with congruent word-context mitigating this impairment and enhancing item recognition. Neural results from ERPs and theta oscillations found the recollection process, as shown by the LPC old/new effect and theta oscillations, for both item and source recognition across emotional contexts, irrespective of congruity. Meanwhile, the familiarity process as indexed by the FN400 old/new effect was found only for item recognition in congruent emotional contexts. These findings suggest that the congruent relationship of item-context could mitigate the emotion-induced source memory impairment and enhance item memory, with neural results elucidating the memory processes involved in retrieval of emotional information. Specifically, while emotion-related information generally elicits the recollection-based memory process, only congruent emotional information elicits the familiarity-based process.

The impact of culture on emotion suppression: Insights from an electrophysiological study of emotion regulation in Japan

Prior theory and evidence suggest that native East Asians tend to down-regulate their emotional arousal to negatively valenced experiences through expressive suppression, an emotion regulation technique focused on suppressing one's emotional experience. One proposed explanation for this choice of regulation strategy and its efficacy is rooted in their commitment to the cultural value of interdependence with others. However, prior work has not yet thoroughly supported this hypothesis using in vivo neural correlates of emotion regulation. Here, we utilized an established electroencephalogram (EEG) correlate of emotional arousal, the late positive potential (LPP), to examine whether down-regulation of the LPP in native East Asians might be particularly pronounced for those relatively high in interdependent self-construal. In this study, native Japanese participants attempted to suppress their emotional reaction to unpleasant images during EEG recording. In support of the hypothesis that emotion suppression among native East Asians is influenced by the cultural value of interdependence, there was a significant effect of interdependent self-construal on the LPP. Specifically, those relatively high in interdependent (versus independent) self-construal exhibited a smaller LPP in response to unpleasant pictures when instructed to suppress their emotions versus a passive viewing condition. However, this effect was negligible for those relatively low in interdependent self-construal, suggesting that cultural values impact the in vivo efficacy of different emotion regulation techniques. These results demonstrate the importance of identifying correspondence between self-report measures and in vivo correlates of emotion regulation in cross-cultural research.

Effects of mindfulness and fatigue on emotional processing: an event-related potentials study

Fatigue is a common experience in everyday life. People who experience fatigue will have more intense negative emotions, and at the same time, their positive emotions will decrease, impairing the individual's emotional processing ability. In previous research, mindfulness meditation reduces the intensity of negative emotional stimuli. However, if individuals continue to be affected by negative emotions when they are fatigued, it is unclear whether mindfulness can buffer the negative association between fatigue and emotions. This study examined whether mindfulness meditation affects the association between fatigue and emotions, using event-related potentials (ERPs). One hundred and forty-five participants completed the experiment. They were randomly assigned to the Mindfulness or Non-mindfulness group; and they were presented with positive, neutral, or negative pictures in an emotional processing task before and after mindfulness or rest. Late positive potential (LPP) is an important indicator of emotional stimuli perceived by individuals, and positive or negative pictures can induce an increase in LPP amplitude more than neutral pictures. Our findings suggest that fatigue significantly affected individuals' LPP amplitudes in the early, mid, and late windows in the Non-mindfulness group, specifically, the more fatigued individuals had lower LPP amplitudes, but not in the Mindfulness group. These results suggest that in a state of fatigue, mindful individuals are able to maintain responsiveness to emotional stimuli by maintaining LPP amplitude. Our study has demonstrated that mindfulness meditation, to some extent, offsets the negative association of fatigue with the neural activation of emotions.

Culture and gender modulate dlPFC integration in the emotional brain: evidence from dynamic causal modeling

Past research has recognized culture and gender variation in the experience of emotion, yet this has not been examined on a level of effective connectivity. To determine culture and gender differences in effective connectivity during emotional experiences, we applied dynamic causal modeling (DCM) to electroencephalography (EEG) measures of brain activity obtained from Chinese and American participants while they watched emotion-evoking images. Relative to US participants, Chinese participants favored a model bearing a more integrated dorsolateral prefrontal cortex (dlPFC) during fear v. neutral experiences. Meanwhile, relative to males, females favored a model bearing a less integrated dlPFC during fear v. neutral experiences. A culture-gender interaction for winning models was also observed; only US participants showed an effect of gender, with US females favoring a model bearing a less integrated dlPFC compared to the other groups. These findings suggest that emotion and its neural correlates depend in part on the cultural background and gender of an individual. To our knowledge, this is also the first study to apply both DCM and EEG measures in examining culture-gender interaction and emotion.

The embodiment of emotion-label words and emotion-laden words: Evidence from late Chinese-English bilinguals

Although increasing studies have confirmed the distinction between emotion-label words (words directly label emotional states) and emotion-laden words (words evoke emotions through connotations), the existing evidence is inconclusive, and their embodiment is unknown. In the current study, the emotional categorization task was adopted to investigate whether these two types of emotion words are embodied by directly comparing how they are processed in individuals' native language (L1) and the second language (L2) among late Chinese-English bilinguals. The results revealed that apart from L2 negative emotion-laden words, both types of emotion words in L1 and L2 produced significant emotion effects, with faster response times and/or higher accuracy rates. In addition, processing facilitation for emotion-label words over emotion-laden words was observed irrespective of language operation; a significant three-way interaction between the language, valence and emotion word type was noted. Taken together, this study suggested that the embodiment of emotion words is modulated by the emotion word type, and L2 negative emotion-laden words tend to be affectively disembodied. The disassociation between emotion-label and emotion-laden words is confirmed in both L1 and L2 and therefore, future emotion word research should take the emotion word type into account.

Psychology: Where history, culture, and biology meet

This article argues that the same epistemological assumptions cannot be confidently applied in the transition from the biological to the social arenas of psychology, as a consequence of the sociocultural instability resulting from human linguistic and technological flair. To illustrate this contention, reference is made to historicist theses within critical and sociocultural psychology, the work of Ian Hacking and Norbert Elias, the centrality of language and technology to sociocultural instability, and the illustrative issues raised by cultural neuroscience and replication studies.

Chinese patients' response to doctor-patient relationship stimuli: evidence from an event-related potential study

Background

With improvements in medical technology, the doctor–patient relationship should be further improved. However, disputes between doctors and patients have increased, with the two groups frequently hurting each other. Therefore, we sought to explore the perception of Chinese patients regarding the stimuli of doctor–patient relationships with different valence.

Methods

We used event-related potential (ERP) to explore the brain electrical activity of 19 undergraduate participants who had a clinical experience in the previous 6 months where they perceived negative, neutral, and positive doctor–patient relationships. The ERPs were recorded, and the early ERP components (P2) and late positive potential (LPP) were measured.

Results

Compared with the stimuli of negative doctor–patient relationships, those of positive doctor–patient relationships would attract more attention and have larger P2 amplitude; LPP was larger for the stimuli of negative doctor–patient relationships than neutral ones in the 500–800 ms, while in the 1100–1500 ms, the stimuli of neutral doctor–patient relationships elicited larger LPP amplitude than positive ones.

Conclusion

Patients paid more attention to the stimuli of positive doctor–patient relationships because they expected to have the same positive relationship. Although threatening elements in negative doctor–patient relationships would catch patients’ attention and make them have implicit emotional regulation, neutral stimuli with poker-faced doctors would cause lasting attention. These results illustrate the patients’ real perception of the different valence of doctor–patient relationship stimuli.

Impact of a mindfulness-based school curriculum on emotion processing in Vietnamese pre-adolescents: An event-related potentials study

The neurocognitive mechanisms associated with mindfulness training in children are not well understood. This randomised controlled study with active and passive control groups examined the impact of an 18-week mindfulness curriculum delivered by schoolteachers on emotion processing in Vietnamese 7- to 11-year-olds. Event-related potential markers indexed emotion processing while children were completing emotional Go/No-Go tasks before and after mindfulness training, and at 6-month follow-up. In an oddball Go/No-Go task with Caucasian faces no changes in P3b and LPP components were detected, but in a Go/No-Go task with Caucasian and Japanese faces changes were observed in P3b latencies and LPP mean amplitudes. Specifically, the P3b in response to angry non-targets for Japanese faces peaked later in the mindfulness training group (TG) at 6-months follow-up in comparison to the non-intervention control group (NCG). The LPP mean amplitudes for averaged Caucasian and Japanese angry non-targets were also attenuated in the TG at 6-month follow-up. In contrast, no changes in the LPP mean amplitudes were observed for the NCG over time. Together, these findings may indicate that mindfulness training in pre-adolescents enhances emotional non-reactivity to negative distractors. A fluctuating pattern of LPP mean amplitude modulations for angry targets was observed in the active control group (ACG) receiving social-emotional learning (SEL) training. Overall, findings from this study suggest that mindfulness training in pre-adolescents enhances emotional non-reactivity to negative distractors and some of the effects are culturally sensitive.

Investigating the associations between cognitive appraisals, emotion regulation and symptoms of posttraumatic stress disorder among Asian American and European American trauma survivors

This study investigated whether the associations between emotion regulation and cognitive appraisals and symptoms of posttraumatic stress disorder (PTSD) differ between Asian American and European American trauma survivors. Asian American (n = 103) and European American (n = 104) trauma survivors were recruited through mTurk and completed an on-line questionnaire assessing cognitive appraisals, emotion regulation and PTSD symptomatology. The European American group reported greater trauma-specific rumination, psychological inflexibility, seeking out others for comfort, and negative self-appraisals than the Asian American group. The Asian American group reported greater secondary control appraisals and cultural beliefs about adversity than the European American group. Second, cultural group moderated the associations between (a) brooding rumination, (b) fatalism, (c) self-blame, and (d) negative communal self-appraisals and PTSD symptoms. These associations were larger for the European American group than the Asian American group. Third, there was an indirect pathway from self-construal (independent and interdependent) to PTSD symptoms through certain emotion regulation approaches and cognitive appraisals. Additionally, cultural group was found to moderate several of these indirect effects. These findings highlight the importance of considering cultural background and cultural values in understanding the processes involved in PTSD. Further research in this area is needed.

Outside the "Cultural Binary": Understanding Why Latin American Collectivist Societies Foster Independent Selves

Cultural psychologists often treat binary contrasts of West versus East, individualism versus collectivism, and independent versus interdependent self-construal as interchangeable, thus assuming that collectivist societies promote interdependent rather than independent models of selfhood. At odds with this assumption, existing data indicate that Latin American societies emphasize collectivist values at least as strongly as Confucian East Asian societies, but they emphasize most forms of independent self-construal at least as strongly as Western societies. We argue that these seemingly "anomalous" findings can be explained by societal differences in modes of subsistence (herding vs. rice farming), colonial histories (frontier settlement), cultural heterogeneity, religious heritage, and societal organization (relational mobility, loose norms, honor logic) and that they cohere with other indices of contemporary psychological culture. We conclude that the common view linking collectivist values with interdependent self-construal needs revision. Global cultures are diverse, and researchers should pay more attention to societies beyond "the West" and East Asia. Our contribution concurrently illustrates the value of learning from unexpected results and the crucial importance of exploratory research in psychological science.

The neural bases of expressive suppression: A systematic review of functional neuroimaging studies

Expressive suppression refers to the inhibition of emotion-expressive behavior (e.g., facial expressions of emotion). Although it is a commonly used emotion regulation strategy with well-documented consequences for well-being, little is known about its underlying mechanisms. In this systematic review, we for the first time synthesize functional neuroimaging studies on the neural bases of expressive suppression in non-clinical populations. The 12 studies included in this review contrasted the use of expressive suppression to simply watching emotional stimuli. Results showed that expressive suppression consistently increased activation of frontoparietal regions, especially the dorsolateral and ventrolateral prefrontal cortices and inferior parietal cortex, but decreased activation in temporo-occipital areas. Results regarding the involvement of the insula and amygdala were inconsistent with studies showing increased, decreased, or no changes in activation. These mixed findings underscore the importance of distinguishing expressive suppression from other forms of suppression and highlight the need to pay more attention to experimental design and neuroimaging data analysis procedures. We discuss these conceptual and methodological issues and provide suggestions for future research.

Trait boldness and emotion regulation: An event-related potential investigation

The present study sought to extend knowledge of the role of boldness, a transdiagnostic bipolar trait dimension involving low sensitivity to threat, in emotional reactivity and regulation using physiological and report-based measures. One prior study found that boldness was associated with reduced late positive potential (LPP) while passively viewing aversive images, but not during emotion regulation; a disconnect between LPP and self-reported reactivity was also observed. Here, participants (N = 63) completed an emotion regulation task in which they either passively viewed or effortfully up- or downregulated their emotional reactivity to pleasant, unpleasant, and neutral pictures while EEG activity was recorded; they later retrospectively rated the success of their regulation efforts. ANOVAs examining the interactive effects of regulation instruction and boldness on LPP amplitude revealed that lower boldness (higher trait fearfulness) was associated with paradoxical increases in LPP to threat photos during instructed downregulation, relative to passive viewing, along with lower reported regulation success on these trials. Unexpectedly, similar LPP effects were observed for affective images overall, and especially nurturance photos. Although subject to certain limitations, these results suggest that individual differences in boldness play a role not only in general reactivity to aversive stimuli, as evidenced by prior work, but in the ability to effortfully downregulate emotional response.

Identifying similarities and differences in emotion recognition with EEG and eye movements among Chinese, German, and French people

OBJECTIVE

Cultures have essential influences on emotions. However, most studies on cultural influences on emotions are in the areas of psychology and neuroscience, while the existing affective models are mostly built with data from the same culture. In this paper, we identify the similarities and differences among Chinese, German, and French individuals in emotion recognition with electroencephalogram (EEG) and eye movements from an affective computing perspective.

APPROACH

Three experimental settings were designed: intraculture subject dependent, intraculture subject independent, and cross-culture subject independent. EEG and eye movements are acquired simultaneously from Chinese, German, and French subjects while watching positive, neutral, and negative movie clips. The affective models for Chinese, German, and French subjects are constructed by using machine learning algorithms. A systematic analysis is performed from four aspects: affective model performance, neural patterns, complementary information from different modalities, and cross-cultural emotion recognition.

MAIN RESULTS

From emotion recognition accuracies, we find that EEG and eye movements can adapt to Chinese, German, and French cultural diversities and that a cultural in-group advantage phenomenon does exist in emotion recognition with EEG. From the topomaps of EEG, we find that the gamma and beta bands exhibit decreasing activities for Chinese, while for German and French, theta and alpha bands exhibit increasing activities. From confusion matrices and attentional weights, we find that EEG and eye movements have complementary characteristics. From a cross-cultural emotion recognition perspective, we observe that German and French people share more similarities in topographical patterns and attentional weight distributions than Chinese people while the data from Chinese are a good fit for test data but not suitable for training data for the other two cultures.

SIGNIFICANCE

Our experimental results provide concrete evidence of the in-group advantage phenomenon, cultural influences on emotion recognition, and different neural patterns among Chinese, German, and French individuals.

A mindfulness-based mobile health (mHealth) intervention among psychologically distressed university students in quarantine during the COVID-19 pandemic: A randomized controlled trial

This randomized controlled trial evaluated the effect of a mindfulness-based mobile health (mHealth) intervention, tailored to the pandemic context, among young adult students (N = 114) with elevated anxiety and/or depressive symptoms during quarantine in China, compared to a time- and attention-matched social support-based mHealth control. At baseline, postintervention (1 month), and 2-month follow-up, participants completed self-reports of primary outcomes (anxiety and depression), secondary outcomes (mindfulness and social support), and emotional suppression as a culturally relevant mechanism of change. Feasibility and acceptability were also evaluated. Using intent-to-treat (ITT) analysis, linear mixed effects models showed that compared to social support mHealth, mindfulness mHealth had a superior effect on anxiety (p = .024, between-group d = 0.72). Both conditions improved on depression (baseline-to-FU ds > 1.10, between-group difference not significant, d = 0.36 favoring mindfulness). There was an interaction of Emotional suppression reduction × Condition in the improvement of anxiety and depression. Further, mindfulness mHealth was demonstrated to be more feasible and acceptable in program engagement, evaluation, skills improvement, and perceived benefit. Retention was high in both conditions (>80%). The difference in self-reported adverse effect was nonsignificant (3.9% in mindfulness and 8.7% in social support). Results of this pilot trial suggest that both mindfulness and social support, delivered via mHealth, show promise in reducing distress among young adults in quarantine, with mindfulness being particularly effective in addressing anxiety. Successful implementation and dissemination of this mHealth intervention approach have the potential for addressing the psychological consequences of the pandemic.

Emotion depends on context, culture and their interaction: evidence from effective connectivity

Situated models of emotion hypothesize that emotions are optimized for the context at hand, but most neuroimaging approaches ignore context. For the first time, we applied Granger causality (GC) analysis to determine how an emotion is affected by a person's cultural background and situation. Electroencephalographic recordings were obtained from mainland Chinese (CHN) and US participants as they viewed and rated fearful and neutral images displaying either social or non-social contexts. Independent component analysis and GC analysis were applied to determine the epoch of peak effect for each condition and to identify sources and sinks among brain regions of interest. We found that source-sink couplings differed across culture, situation and culture × situation. Mainland CHN participants alone showed preference for an early-onset source-sink pairing with the supramarginal gyrus as a causal source, suggesting that, relative to US participants, CHN participants more strongly prioritized a scene's social aspects in their response to fearful scenes. Our findings suggest that the neural representation of fear indeed varies according to both culture and situation and their interaction in ways that are consistent with norms instilled by cultural background.

Effect of the congruity of emotional contexts at encoding on source memory: Evidence from ERPs

Emotion's influence on source memory has proven more elusive and the lack of studies investigates the effect of the congruent emotional contexts on source memory. Here, we investigated these issues using event-related potentials (ERPs) to assess emotional-induced neural correlates. During encoding, congruent word-picture (a word 'shoes' - a picture described shoes) and incongruent word-picture (a word 'pepper' - a picture described shoes) with a prompt (Common? or Natural?) were presented. At retrieval, participants indicated which prompts were concomitantly presented with the word during encoding. Behavioral results revealed that source memory accuracy was enhanced in the neutral contexts compared to the negative contexts, and enhanced in the incongruent condition relative to the congruent condition, suggesting that emotional contexts impaired source memory performance, and incongruent information enhanced source memory. ERPs results showed that early P2 old/new effect (150-250 ms) and FN400 old/new effect (300-450 ms) were observed for words with correct source that had been encoded in the congruent emotional contexts, and that a larger parietal old/new effect, between 500 and 700 ms, was observed for words with correct source that had been encoded in the incongruent condition than in the congruent condition, irrespective the nature of context. The ERPs results indicate that retrieval of source details for the associated emotionally congruent information supports the idea that emotional events could attract more attentional resources, and reflects the contribution of familiarity-based process. Meanwhile, retrieval of source details for the associated incongruent information reflects a stronger contribution of recollection-based process.

How Facial Attractiveness Affects Time Perception: Increased Arousal Results in Temporal Dilation of Attractive Faces

Time perception plays a fundamental role in people’s daily life activities, and it is modulated by changes in environmental contexts. Recent studies have observed that attractive faces generally result in temporal dilation and have proposed increased arousal to account for such dilation. However, there is no direct empirical result to evidence such an account. The aim of the current study, therefore, was to clarify the relationship between arousal and the temporal dilation effect of facial attractiveness by introducing a rating of arousal to test the effect of arousal on temporal dilation (Experiment 1) and by regulating arousal via automatic expression suppression to explore the association between arousal and temporal dilation (Experiment 2). As a result, Experiment 1 found that increased arousal mediated the temporal dilation effect of attractive faces; Experiment 2 showed that the downregulation of arousal attenuated the temporal dilation of attractive faces. These results highlighted the role of increased arousal, which is a dominating mechanism of the temporal dilation effect of attractive faces.

The Immediate and Lasting Effect of Emotion Regulation in Adolescents: An ERP Study

The immediate effect is an important index of the outcomes of emotion regulation. However, in daily life, whether the effect of emotion regulation lasts and the lasting mechanism have been examined less. The present research focused on the relationships between the immediate and lasting effect of the emotion regulation of adolescents. Electroencephalogram (EEG) was recorded from 51 adolescents (31 boys and 20 girls, Mage = 12.82) during online emotion regulation using the Reactivity and Regulation-Image Task (phase 1) and re-presentation of emotional stimuli after a period of time (phase 2). Event-related potentials (ERPs) related to emotion regulation, such as N2, P3, and the late positive potential (LPP), were examined in the two phases. The results showed that: (1) In both of the two phases, in negative emotion conditions, the amplitudes of P3 and LPP 300-600 of no-regulation conditions were significantly higher than those in reappraisal conditions. However, there was no significant difference under neutral conditions; (2) The amplitudes of P3, N2, and LPP 300-600 during emotion regulation in phase 1 positively predicted the amplitudes of P3, N2, and LPP300-600 in phase 2 in different experimental conditions. Results from the regression analysis implied that the immediate effect of online emotion regulation may predict the lasting effect when adolescents face the same emotions again. In addition, our findings provide neurological evidence that the use of cognitive reappraisal could effectively help adolescents to reduce the recruitment of cognitive resources when they regulate negative emotions and when they face those negative emotions again.

Culture, Sex, and Group-Bias in Trait and State Empathy

Empathy is sharing and understanding others’ emotions. Recently, researchers identified a culture–sex interaction effect in empathy. This phenomenon has been largely ignored by previous researchers. In this study, the culture–sex interaction effect was explored with a cohort of 129 participants (61 Australian Caucasians and 68 Chinese Hans) using both self-report questionnaires (i.e., Empathy Quotient and Interpersonal Reactivity Index) and computer-based empathy tasks. In line with the previous findings, the culture–sex interaction effect was observed for both trait empathy (i.e., the generalized characteristics of empathy, as examined by the self-report questionnaires) and state empathy (i.e., the on-spot reaction of empathy for a specific stimulus, as evaluated by the computer-based tasks). Moreover, in terms of state empathy, the culture–sex interaction effect further interacted with stimulus traits (i.e., stimulus ethnicity, stimulus sex, or stimulus emotion) and resulted in three- and four-way interactions. Follow-up analyses of these higher-order interactions suggested that the phenomena of ethnic group bias and sex group favor in empathy varied among the four culture–sex participant groups (i.e., Australian female, Australian male, Chinese female, and Chinese male). The current findings highlighted the dynamic nature of empathy (i.e., its sensitivity toward both participant traits and stimulus features). Furthermore, the newly identified interaction effects in empathy deserve more investigation and need to be verified with other Western and Asian populations.

Evaluation of a Blended Career Education Course during the COVID-19 Pandemic on Students’ Career Awareness

Higher education has increasingly emphasized the importance of employability traits in order to personalize students’ learning needs and meet dynamic workplace demands. Previous research addressing the personalized learning on career education in blended learning model is limited. The present study aims to examine whether students with distinctive stable personality traits would improve their career adaptability and adaptation results after attending a synchronous career course during the COVID-19 pandemic. A total of 162 participants completed the questionnaires at both the first and last sessions of the course in spring 2020. Findings revealed that the course positively improved students’ identity formation. Personality traits demonstrated significant main effects on the middle identity formation stage and career adaptability. This study highlights traits such as emotional stability and possible cultural effects on the career development course in the young Chinese sample population. The implication of specific attributes and cultural backgrounds in career development courses is discussed.

The Three Teachings of East Asia (TTEA) Inventory: Developing and Validating a Measure of the Interrelated Ideologies of Confucianism, Buddhism, and Taoism

Objectives: Buddhism, Taoism, and Confucianism have influenced societies and shaped cultures as they have spread across the span of history and ultimately across the world. However, to date, the interrelated nature of their impacts has yet to be examined largely due to the lack of a measure that comprehensively assesses their various tenets. Building on a conceptual integration of foundational texts on each ideology as well as on recent measure development work (much of which is unpublished), the current studies developed a comprehensive measure of these ideologies (the Three Teachings of East Asia Inventory; TTEA) and validated it across four languages.

Methods: A combined sample of 2,091 online respondents (Study 1: 322 Chinese respondents, Study 2: 400 Japanese respondents, Study 3: 362 Taiwanese respondents, Study 4: 688 White Americans and 319 Asian Americans) completed 25–35 min online survey in their preferred language: English, Traditional Mandarin, Simplified Mandarin, or Japanese.

Results: Exploratory Factor Analyses within a 122-item pool identified 18 stable dimensions across all samples. Measurement invariance analyses identified the final 61-items of the TTEA inventory (demonstrating reasonable invariance across all languages), confirming 18 individual tenet subscales that organize into four higher-order composites: Buddhism, Taoism, Restrictive Confucianism, and Empowering Confucianism. A shorter 36-item version of the TTEA inventory was also developed. The TTEA scales demonstrated (1) acceptable internal consistency, (2) discriminant validity, and (3) incremental predictive validity for current life satisfaction and vitality.

Conclusions: The TTEA inventory offers one of the first comprehensive, multilingual measures that will allow cross-cultural researchers to examine the influence of three related Eastern ideologies on societies across the world.

Automatic Suppression Reduces Anxiety-Related Overestimation of Time Perception

Anxiety has been found to lengthen time perception, especially the time perception of negative stimuli. This anxiety-related time overestimation is thought to be mainly associated with massively increased arousal. Suppression, which can be achieved either deliberately or automatically, has been demonstrated to be effective in reducing arousal. Consequently, the present study explored the effectiveness of both deliberate suppression (Experiment 1) and automatic suppression (Experiment 2) in reducing the time distortion in anxiety. A temporal bisection task (TBT), featuring negative and neutral pictures, was used to measure time perception, while the self-reported arousal was used to assess arousal. The deliberate suppression was manipulated by asking participants to suppress their emotional expressions; while automatic suppression was manipulated through a sentence-unscrambling task featuring suppression-related words, which can unconsciously prime suppression. The results of Experiment 1 showed that deliberate suppression did not reduce the anxiety-related time overestimation and arousal. However, Experiment 2 showed that automatic suppression significantly reduced the anxiety-related time overestimation, with significant arousal reduction being observed. In conclusion, automatic suppression, but not deliberate suppression, is effective for reducing the effect of anxiety on time perception.

The Suppression Paradox: A Cross-Cultural Comparison of Suppression Frequency, Suppression Ability, and Depression

The habitual use of expressive suppression (suppression frequency) is consistently associated with a number of negative outcomes, but paradoxically, the ability to suppress when there is a situational need (suppression ability) is usually linked to positive outcomes. The two sides of the paradox, suppression frequency and suppression ability, have been found to be unrelated. Given that these findings have emerged in largely western samples, the present studies examined whether the coupling of suppression frequency and ability depends on cultural contexts, and whether this can explain the previously established cultural difference in the costs of suppression frequency. In an initial study, we examined the relations among suppression frequency, suppression ability, and depression in a Chinese sample (Study 1; N = 310), and then, using two new samples, we compared these relations between Chinese and the US samples (Study 2; N = 392). Results showed that suppression frequency was related to depression in two distinct ways. In both cultures, suppression frequency had a direct, positive association with depression. In Chinese culture only, however, suppression frequency also had an indirect association, such that higher suppression frequency was related to higher suppression ability and in turn related to fewer depressive symptoms. Our findings show that suppression frequency is related to suppression ability only among Chinese participants, and can serve as a potential explanation for why suppression frequency is less related to depression in Chinese culture.

How Grief, Funerals, and Poverty Affect Bereaved Health, Productivity, and Medical Dependence in Japan

Grief has been shown to weaken bereaved persons' health, but measurements of their lost time and medical expense remain rare. Funerals traditionally managed and assuaged grief through ritual expression, approval, and social support. Research suggests that satisfying funeral participation reduces grief, while poverty exacerbates it. We hypothesized that: (1) psycho-physical symptoms of grief, (2) abbreviation/dissatisfaction in the funeral, and (3) poverty, correlate with decreased productivity and increased medical and social services use. We collected data from 165 mourning families about their grief, funerals, and subsequent medical conditions. (1) Deeper grief after bereavement in Japan correlated with more physical problems, more down time, and more medical dependency. (2) Low satisfaction with funerals correlated with higher hospital, pharmacy, and counseling costs. (3) Low income families lost more time, while declining incomes showed increased pharmaceutical costs. This suggests that satisfying funerals and income safeguards may reduce costs of low productivity and increased public services dependency.

Cultural neuroscience and the research domain criteria: Implications for global mental health

A comprehensive understanding of the basic molecular and cellular mechanisms of the brain is important for the scientific discovery of root causes, risk and protective factors for mental disorders in global mental health. Systematic research in cultural neuroscience within the research domain criteria (RDoC) framework investigates the fundamental biobehavioral dimensions and observable behavior across cultures. Cultural dimensions are characterized in elements of circuit-based mechanisms and behavior across a range of analysis. Research approaches in cultural neuroscience within the RDoC framework advance the evidence-based resources for the development and implementation of cures, preventions and interventions to mental disorders in global mental health. This review presents a novel synthesis of foundations in cultural neuroscience within the research domain criteria framework to advance integrative, translational efforts in discovery and delivery science of mental disorders across cultural contexts in global mental health.

Mapping Cultural Values onto the Brain: the Fragmented Landscape

Basic values are the core element of culture, explaining many important differences in social, economic and political effects. Yet the nature and the composition of cultural value systems remains highly debatable. An emerging field of cultural neuroscience promises to shed light on how societies differ in their value systems and on the low-level mechanisms through which they operate. A systematic review of 47 experimental studies using different brain research methods is conducted to identify neural systems and processes, which can be associated with specific values, irrespective of interpretations given by the authors of original studies. Key findings were extracted and systematized according to Hofstede's and some other (Trompenaars' and Gelfand's) models of national cultures. From the perspective of existing accounts of cultural value systems, existing literature provides only a very fragmented and biased view of the neural processing of values. Absolute majority of existing evidence (37 studies) of cultural differences in the brain functions can be associated with individualism-collectivism value dimension. Affectivity-Neutrality is identified in 11 studies, Tightness-Looseness - 6, Power Distance - 3; Indulgence, Long-Term Orientation and Universalism - 2, and Uncertainty Avoidance - 1. Other value dimensions from the applied models of culture are not represented at all. Key problems limiting the contribution of the contemporary culture neuroscience to the comparative studies of cultural values include: researchers' theoretical framing within the independence-interdependence paradigm, resulting in the loss of a broader perspective and alternative interpretations of findings, the lack of focus on the direct comparison of values and value dimensions, insufficiently representative and biased samples.

Neural signatures of child cognitive emotion regulation are bolstered by parental social regulation in two cultures

Caregiver impact on the efficacy of cognitive emotion regulation (ER; i.e. reappraisal) during childhood is poorly understood, particularly across cultures. We tested the hypothesis that in children from Japan and the USA, a neurocognitive signature of effective reappraisal, the late positive potential (LPP), will be bolstered by cognitive scaffolding by parents, and explored whether the two cultures differed in whether mere physical proximity of parents provides similar benefit. Five-to-seven-year-olds (N = 116; n_Japan = 58; n_USA = 58) completed a directed reappraisal task (EEG-recorded) in one of three contexts: (i) parent-scaffolding, (ii) parent-present and (iii) parent-absent. Across cultures, those in the parent-scaffolding group and parent-present group showed effective reappraisal via the LPP relative to those in the parent-absent group. Results suggest that scaffolding is an effective method through which parents in these two cultures buttress child ER, and even parental passive proximity appears to have a meaningful effect on child ER across cultures.

The Effectiveness of a Mindfulness-Based Psychoeducation Programme for Emotional Regulation in Individuals with Schizophrenia Spectrum Disorders: A Pilot Randomised Controlled Trial

BACKGROUND

Emotion dysregulation has emerged as a transdiagnostic factor that potentially exacerbates the risk of early-onset, maintenance, and relapse of psychosis. Mindfulness is described as the awareness that emerges from paying attention to the present moment without judgment. It gently pulls the mind out of the negative emotions induced by the disparity between expectation and reality by focusing on the present moment, instead of worrying about the future or regretting the past. However, only a few research has ever focused on the efficacy of using a mindfulness-based intervention to improve emotion regulation in schizophrenia spectrum disorders.

PURPOSE

The purpose of this study was to examine the effectiveness of a Mindfulness-Based Psychoeducation Programme (MBPP) on the emotion regulation of individuals with schizophrenia, in particular, to access emotion regulation strategies. The objective of this study was to find out whether MBPP is feasible for improving emotion regulation strategies, in terms of rumination, cognitive reappraisal, and expressive suppression, with a sustainable effect at a three-month follow-up.

PATIENTS AND METHODS

A single-blinded pilot randomised controlled trial with repeated-measures designs was adopted. Forty-six participants diagnosed with schizophrenia and its subtypes were randomised in either the 8-week mindfulness-based psychoeducation programme or treatment-as-usual (control) group.

RESULTS

The results of the Generalised Estimating Equations test indicated that the MBPP group showed a significant improvement in reappraisal at a three-month follow-up (β = -6.59, Wald's χ ²=4.55, p=0.033), and a significant reduction in rumination across time. However, the Generalised Estimating Equations indicated no significant difference in rumination and expressive suppression in the MBPP group. Two participants reported having unwanted experiences, including feelings of terror and distress during the mindfulness practice.

CONCLUSION

The MBPP appeared to be effective for improving emotion regulation, which will contribute to future large-scale RCT to confirm the treatment effects in more diverse groups of schizophrenic patients.

Neural underpinnings of the relationships between sensation seeking and emotion regulation in adolescents

There is little neurological evidence linking sensation seeking and emotion regulation in adolescence, which is characterised as an emotionally fluctuant period. The present study examined the relationship between sensation seeking and emotion regulation in adolescents. Electroencephalograms were recorded from 22 high sensation-seeking adolescents (HSSs, M_age  = 12.36) and 24 low sensation-seeking adolescents (LSSs, M_age  = 12.84) during the reactivity and regulation-image task. Group differences in event-related brain potentials (ERPs) associated with the regulation of negative and neutral stimuli were analysed. The results showed that (a) the P2 of HSSs were larger than LSSs during emotion regulation; (b) in down-regulation conditions, the LPP in all time windows were smaller than no-regulation in LSSs. However, there was no significant difference in HSSs; (c) the LPP 300-600 and LPP 1000-1500 of down-regulation were smaller in LSSs than HSSs; (d) for LPP 600-1000, HSSs induced larger LPP than LSSs in the negative down-regulation and negative no-regulation conditions. The results provide neurological evidence that higher sensation seeking is related to the high reactivity to emotional stimuli and poor cognitive control during the regulation of emotions.

The relation between emotion regulation and migraine: A cross-cultural study on the moderating effect of culture

BACKGROUND

Effects of emotion suppression on physical health might be contingent on culture. Existing research on emotion regulation has mainly included western participants. Herewith the question arises, whether this gained expertise is transferable to an Asian culture.

OBJECTIVES

This cross-sectional study evaluated to what extent the regulation of emotions is related to migraine and if the relation between emotion regulation and migraine complaints differs between a Western and an Asian population. Therefore, the main characteristics and symptoms of patients with migraine from both Germany and Japan are compared.

METHODS

261 Japanese and 347 German headache patients participated in this online study and completed self-report measures of emotion regulation (suppression and reappraisal) and headache complaints.

RESULTS

Cultural groups did not differ regarding their demographic data, intake of medication and number of days with headache. German participants showed significantly higher levels of anxiety and lower levels of emotion suppression compared to Japanese patients. Emotion regulation is not correlated with headache complaints either in the Japanese or in the German patient group.

CONCLUSION

Although group differences were found with respect to anxiety and emotion suppression, subsequent regression analysis revealed these differences were unrelated to headache complaints. As our baseline analysis focused on group means, approaches that examine individual reaction patterns to stress and accompanying sensory stimulus processing may prove to be more fruitful and illuminating.

Cultural Differences in Perceptual Strategies Underlying Emotion Regulation

Cultural norms for the experience, expression, and regulation of emotion vary widely between individualistic and collectivistic cultures. Collectivistic cultures value conformity, social harmony, and social status hierarchies, which demand sensitivity and focus to broader social contexts, such that attention is directed to contextual emotion information to effectively function within constrained social roles and suppress incongruent personal emotions. By contrast, individualistic cultures valuing autonomy and personal aspirations are more likely to attend to central emotion information and to reappraise emotions to avoid negative emotional experience. Here we examined how culture affects perceptual strategies employed during emotion regulation, particularly during cognitive reappraisal and emotional suppression. Eye movements were measured while healthy young adult participants viewed negative International Affective Picture System (IAPS) images and regulated emotions by using either strategies of reappraisal (19 Asian American, 21 Caucasian American) or suppression (21 Asian American, 23 Caucasian American). After image viewing, participants rated how negative they felt as a measure of subjective emotional experience. Consistent with prior studies, reappraisers made lower negative valence ratings after regulating emotions than suppressers across both Asian American and Caucasian American groups. Although no cultural variation was observed in subjective emotional experience during emotion regulation, we found evidence of cultural variation in perceptual strategies used during emotion regulation. During middle and late time periods of emotional suppression, Asian American participants made significantly fewer fixations to emotionally salient areas than Caucasian American participants. These results indicate cultural variation in perceptual differences underlying emotional suppression, but not cognitive reappraisal.

A biocultural approach to psychiatric illnesses

RATIONALE

As a species, humans are vulnerable to numerous mental disorders, including depression and schizophrenia. This susceptibility may be due to the evolution of our large, complex brains, or perhaps because these illnesses counterintuitively confer some adaptive advantage. Additionally, cultural and biological factors may contribute to susceptibility and variation in mental illness experience and expression. Taking a holistic perspective could strengthen our understanding of these illnesses in diverse cultural contexts.

OBJECTIVES

This paper reviews some of these potential factors and contextualizes mental disorders within a biocultural framework.

RESULTS

There is growing evidence that suggests cultural norms may influence inflammation, neurotransmitters, and neurobiology, as well as the illness experience. Specific examples include variation in schizophrenia delusions between countries, differences in links between inflammation and emotion between the United States and Japan, and differences in brain activity between Caucasian and Asian participants indicating that cultural values may moderate cognitive processes related to social cognition and interoception.

CONCLUSIONS

Research agendas that are grounded in an appreciation of biocultural diversity as it relates to psychiatric illness represent key areas for truly interdisciplinary research that can result in culturally sensitive treatments and highlight possible biological variation affecting medical treatment.

Subcultural Differences in Processing Social and Non-social Positive Emotions Between Han and Uygur Chinese: An ERP Study

While previous studies have shown that East-West cultural differences exist in processing different emotional stimuli, potential subcultural differences within a large cultural group are not well understood. In this study, we examined subcultural differences in the event-related potential (ERP) modulations in the brain, during processing social positive and non-social positive stimuli among 21 Han Chinese and 21 Uygur Chinese. Results showed that the magnitudes of P2, N2, and late positive potential (LPP) were larger in Uygur Chinese than in Han Chinese. For social positive stimuli, the P2 and LPP 300–600 were larger in Uygur Chinese than in Han Chinese. However, there was no significant difference in non-social positive stimuli. These results indicated that social positive emotions were more prioritized in emotional processing among Uygur Chinese than Han Chinese. These findings contribute to the growing literature on subcultural differences in processing different types of positive stimuli.

Longitudinal Relations between Emotion Restraint Values, Life Stress, and Internalizing Symptoms among Vietnamese American and European American Adolescents

Objective: Recent research has documented cultural differences in the extent and manner in which various forms of emotion regulation are linked with psychological well-being. Most of these studies, however, have been cross-sectional, nor have they directly examined the values underlying the use of emotion regulation. The present study examined emotion restraint values and their interactions with life stress in predicting internalizing symptoms across time among Vietnamese American and European American adolescents. The study focused on adolescence as a critical developmental period during which life stress and internalizing symptoms increase significantly. Method: Vietnamese American (n = 372) and European American (n = 304) adolescents' levels of emotion restraint values, internalizing symptoms, and stress were assessed at two timepoints six months apart. Results: Results indicated differential associations between emotion restraint values, stress, and symptoms over time for the two groups. For Vietnamese American adolescents, emotion restraint values did not predict depressive, anxiety, or somatic symptoms. For European American adolescents, emotion restraint values predicted higher somatic symptoms but buffered against the effects of interpersonal stress on anxiety and depressive symptoms. Conclusions: These results provide increased understanding of the role of values related to emotion restraint in shaping adolescent internalizing symptoms and responses to stress across cultural groups. Implications of the findings for guiding intervention efforts are discussed.

Cultural Differences in Interpersonal Emotion Regulation

Cultural differences exist in the use of emotion regulation (ER) strategies, but the focus to date has been on intrapersonal ER strategies such as cognitive reappraisal. An emerging literature highlights the importance of interpersonal ER, which utilizes social cues to facilitate the regulation of emotional states. In cultures that place high value on social interconnectedness as integral to their collectivistic self-construal, including East Asian cultures, interpersonal ER strategies may be particularly effective in reducing negative affect but this has not been previously tested. In this study, two groups comprising East Asian (n = 48) and Western European (n = 38) participants were randomly assigned to receive a priming narration depicting the use of either interpersonal (e.g., social modeling, perspective taking) or intrapersonal (e.g., cognitive reappraisal) ER strategies during a stressful experience. They were then instructed to utilize similar ER strategies in an emotion reactivity task during which they viewed high arousing negative pictorial stimuli while their heart rate (HR), heart rate variability (high frequency power - HF-HRV) and subjective affective states were measured. First we found that the East Asian group reported higher use of interpersonal ER strategies of social modeling and perspective taking in daily life. During the experimental interpersonal prime exposure, the East Asian group showed elevated HF-HRV (relative to baseline) compared to the Western European group, indicating more adaptive ER, but this pattern was not sustained during the reactivity or recovery phases. Instead, the East Asian group demonstrated increased HF-HRV and decreased HR across both prime conditions. The East Asian group also showed greater decreases in positive affect across the course of the experiment. Furthermore, individual differences in social modeling and individualistic self-construal moderated the effect of the ER prime in the East Asian group at trend levels, and main effects for perspective taking and reappraisal were observed in the Western European group. The findings support the notion that engaging in interpersonal ER strategies may be more beneficial for East Asian groups when immediately exposed to a stressful situation, as these strategies are congruent with cultural context and preferences, but our priming methodology may have limited the longer-term benefits.

Validation of an electronic version of the Self-Awareness Questionnaire in English and Italian healthy samples

OBJECTIVES

Interoception is a general sensitivity to bodily sensations that informs motivational processes and behaviours. Interoceptive abilities seem to be impaired in several clinical conditions, and the development of new pragmatic instruments to assess subjective components of interoception are crucially needed. An easy to use paper and pencil questionnaire measuring sensitivity to bodily sensations was validated in an Italian sample (Self-Awareness Questionnaire; SAQ).

METHODS

In the present study, we created and evaluated an electronic version of the SAQ in Italian and English language.

RESULTS

Psychometric properties of both electronic versions of the SAQ were validated in an Italian (n = 206) and an English (n = 275) sample, using factorial analyses. Differences in factorial structures observed between the two samples were discussed in terms of cultural impact on emotional regulation and bodily sensations processing.

CONCLUSIONS

The electronic version of SAQ in English and Italian provides a pragmatic and validated tool to evaluate bodily signal sensitivity in clinical settings, informing the development of a new therapy targeting interoceptive processes, in a wide range of psychopathological conditions.

Why Behavioral Indicators May Fail to Reveal Mental States: Individual Differences in Arousal-Movement Pattern Relationships

It is commonly assumed that behavior reflects the mental states of individuals. However, recent attempts to detect human states of mind via behavioral indicators have not always been successful; behavioral indicators may be unreliable and invalid. In this study we show that one of the common behavioral indicators, change in the overall amount of movement, correlated well with changes in the skin conductance level (SCL) at the group level, which reflects changes in arousal. At the individual level, however, changes in the SCL were related to movement patterns only in about half of the individuals. It is also noteworthy that the level of movement-SCL correlation was very highly predictable by certain social and cognitive characteristics of the individuals. Our results suggest that behavioral indicators may in many cases fail to predict mental states at the individual level.

Developmental aspects in cultural neuroscience

Research in cultural neuroscience and development examines the processes and mechanisms underlying the interaction of cultural systems with environmental and biological systems with a life course approach. Culture interacts with environmental and biological factors to shape the mind, brain and behavior across stages of development. Theoretical and empirical approaches in cultural neuroscience investigate how culture influences psychological and neurobiological mechanisms during developmental periods. Methodological approaches in cultural neuroscience and development illustrate the opportunities and challenges with observation and measurement of psychological and biological processes across cultures throughout development. This review examines empirical findings in cultural neuroscience on emotional, cognitive and social development. Implications of theoretical and methodological advances in cultural neuroscience and development for global mental health will be discussed.

Reappraisal and suppression emotion-regulation tendencies differentially predict reward-responsivity and psychological well-being

Individuals who suppress their emotions experience less positive emotions, worse relationships, and a reduced quality of life whereas those who tend to reappraise show an opposite pattern. Despite this divergent pattern, few have asked how the use of these emotion-regulation strategies relates to reward responsivity. We predicted that elevated suppression would be associated with blunted reward responsivity, whereas reappraisal would be associated with elevated reward responsivity. To test this hypothesis, participants completed a measure of individual differences in emotion-regulation strategies, measures of self-reported reward responsivity, and then a reward time-estimation task (Kotani et al., 2003) while electroencephalography (EEG) was recorded. Results revealed that individual differences in cognitive reappraisal were unrelated to self-report measures of reward responsivity, whereas suppression was associated with blunted reward responsivity. At the neural level, reappraisal was associated with greater attention to the rewarding cues, as indexed by the P300 event-related potential (ERP) component, whereas suppression was related to blunted reward anticipation, as indexed by the stimulus-preceding negativity (SPN) ERP component. Suppression prospectively predicted worse psychological well-being 2.5 years later and blunted neural reward anticipation partially explained this association. Taken together with past research, these results suggest reappraisal tendencies may lead to better outcomes due, in part, to enhanced reward responsivity, whereas the negative consequences of suppression may be associated with blunted reward responsivity.

Cultural Factors, Depressive and Somatic Symptoms Among Chinese American and European American College Students

This study seeks to fill a gap in the existing empirical literature about the relationship between somatic and depressive symptoms and their associations with cultural factors among Chinese American and European American college students. In particular, the study examined how three culturally relevant psychological constructs, self-construal, loss of face, and emotion regulation, associate with depressive and somatic symptoms among Chinese American and European American college students and if they can explain possible group differences in depressive symptoms. The sample consisted of 204 Chinese American and 315 European American college students who completed an online survey. Based on multiple regression analyses, European American students reported higher levels of somatic symptoms on the Patient Health Questionnaire–15 (PHQ-15) than Chinese Americans. There was no initial group difference in depressive symptoms based on Center for Epidemiologic Studies–Depression Scale (CES-D) scores. Correlations between depressive and somatic symptoms, independent and interdependent self-construal, and cognitive reappraisal and independent self-construal were stronger for European Americans than Chinese Americans. Somatic symptoms, loss of face, and expressive suppression were positively associated with depressive symptoms, whereas independent self-construal and cognitive reappraisal were negatively associated with depressive symptoms for both groups. When controlling for gender and somatic symptoms, being Chinese American and male was significantly and positively associated with depressive symptoms measured with the CES-D. These ethnic and gender differences in depressive symptoms were explained by independent self-construal, loss of face, cognitive reappraisal, and expressive suppression. Clinical implications include the incorporation of specific culturally relevant constructs and avoidance of race-, ethnicity-, and gender-based stereotypes to reduce health disparities in depression treatment.
