Emotion regulation in adolescents: An ERP study

Desensitized gamers? Violent video game exposure and empathy for pain in adolescents - an ERP study

This Event-Related Potential (ERP) study aimed to test how habitual and short-term violent video game exposure (VVGE) may affect empathy for pain responses in adolescents. In a within-subjects design, boys (N = 56; aged 12-16 years) performed a pain judgment task before and immediately after playing a violent video game. In this task, participants judged whether photos of hands depicted on their screen were in a painful situation or not. While both the P3 and the LPP components were not related to habitual violent video game exposure, general exposure to antisocial media content predicted lower P3 amplitudes to painful pictures. Further, 40 min of violent gameplay did not affect the P3 responses; however, it temporarily decreased LPP responses to painful pictures, suggesting a modest short-term desensitization effect. However, this latter interpretation is limited by a strong LPP pain effect - a significant amplitude difference between painful and non-painful pictures - that remained present in the post-game condition. Such persistent LPP effect may relate to the notion that adolescents are still learning how to properly regulate their emotional reactions. This study contributes to the limited literature on violent video games' desensitization in adolescents' brains, opening new avenues for media violence research.

The mindful trajectory: Developmental changes in mentalizing throughout adolescence and young adulthood

BACKGROUND

Mentalizing and psychological mindedness are two key, partially overlapping facets of social cognition. While mentalizing refers to the ability to reflect on one's own mental states and the mental states of others, psychological mindedness describes the ability for self-reflection and the inclination to communicate with others about one's own mental states.

PURPOSE

This study examined the development of mentalizing and psychological mindedness throughout adolescence and into young adulthood, and the interplay between the two with gender and the Big Five Personality Traits.

METHODS

432 adolescents and young adults (ages 14-30) were recruited from two independent schools and two universities. Participants completed a set of self-report measures.

RESULTS

A curvilinear trend in both mentalizing and psychological mindedness indicated a gradual development of these capacities with age, peaking in young adulthood. Across all age groups, females had consistently higher mentalizing scores than males. For females, scores only changed significantly between age bands 17-18 to 20+ (p<0.001), ES (d = 1.07, 95% CI [.1.52-.62]). However, for males, a significant change in scores appeared between two age bands of 14 to 15-16 (p<0.003), ES (d = .45, 95% CI [.82-.07]), and 17-18 to 20+ (p<0.001), ES (d = .6, 95% CI [.1.08-.1]). The change in psychological mindedness scores differed, and females did not have consistently higher scores than males. Females' scores were only significantly higher for ages 14 (p<0.01), ES (d = .43, 95% CI [.82-.04]), and 15-16 (p<0.01), ES (d = .5, 95% CI [.87-.11]). As with the development of mentalizing abilities, female scores in psychological mindedness remained stable from 14 to 18 years of age, with a significant change between age bands 17-18 and 20+ (p<0.01), ES (d = 1.2, 95% CI [1.7-.67]). Contrastingly, for males significant change occurred between 15-16, 17-18 (p<0.01), ES (d = .65, 95% CI [1.1-.18]) and 20+ (p<0.01), ES (d = .84, 95% CI [1.5-.2]). A significant positive association was found between mentalizing and psychological mindedness and the personality traits of Agreeableness, Openness to Experience and Conscientiousness (p<0.0001). Psychological mindedness had a weaker positive correlation with Extraversion and Openness to Experience (p<0.05).

CONCLUSIONS

The discussion is focused on the interpretation of the findings in light of social cognition and brain development research.

TMS-EEG signatures of facilitated cognitive reappraisal in emotion regulation by left ventrolateral prefrontal cortex stimulation

OBJECTIVE

Left ventrolateral prefrontal cortex (VLPFC) has been demonstrated to be a crucial region involved in the down-regulation of negative affect by cognitive reappraisal. However, the neural evidence of causality is still lacking. The current study was to investigate the contribution of left VLPFC in cognitive reappraisal by using single-pulse transcranial magnetic stimulation (spTMS) and electroencephalogram (EEG).

METHODS

Fifteen participants repeated the cognitive reappraisal task at different TMS settings: no stimulation, spTMS applied at 300 ms after image onset to the left VLPFC, and to the vertex as a control site. EEG and behavioral data were concurrently recorded. TMS-evoked potential (TEP) and late positive potential (LPP) were investigated.

RESULTS

In cognitive reappraisal, left VLPFC stimulation elicited stronger TEPs than vertex stimulation at 180 ms after TMS onset. Increased source activation of TEPs was identified in the precentral gyrus. Emotion regulation by reappraisal enlarged the trough of TEP at stimulation site. The left VLPFC stimulation led to enhanced LPP in cognitive reappraisal, which was negatively correlated with self-reported arousal.

CONCLUSIONS

The TMS stimulation over left VLPFC influences the cognitive reappraisal process by potentiating the neural responses. Accordingly, the cortical region responsible for the execution of cognitive reappraisal is activated. The modulated neural activity is related to the behavioral response. The present study provided neural signatures for the facilitated execution of emotion regulation by left VLPFC stimulation, potentially contributing to the therapeutic protocols for mood disorders.

Cognitive Reappraisal Impairs Negative Affect Regulation in the Context of Social Rejection for Youth With Early-Stage Borderline Personality Disorder

Application of emotion regulation strategies might be susceptible to the context of social rejection for individuals with borderline personality disorder (BPD). This study compared the ability of 27 outpatient youths (15-25 years old) with early-stage BPD and 37 healthy controls (HC) to apply expressive suppression and cognitive reappraisal in standard and socially rejecting laboratory contexts. BPD youths were largely as able as HCs to regulate negative affect across instruction and contexts. However, cognitive reappraisal in the context of social rejection heightened BPD negative facial expression relative to HCs. Thus, while BPD emotion regulation ability was largely normative, cognitive reappraisal might be ineffective in the context of social rejection for this group, with social rejection acting as an accelerant that heightens the expression of negative affect. Given the common experience of perceived and actual social rejection for this group, clinicians should carefully consider treatments that include cognitive reappraisal strategies because they might be contraindicated.

How do risks and benefits affect user' privacy decisions? An event-related potential study on privacy calculus process

Purpose

The purpose of this study is to examine how risks and benefits affect users' privacy-related decision-making processes.

Design/methods/approach

This study collected and analyzed the neural activity processes of users' privacy-related decisions when faced with personalized services with different risks and benefits through an ERP experiment that included 40 participants.

Findings/results

The findings show that users subconsciously categorize personalized services based on benefit; Privacy calculus affects privacy decision by influencing the allocation of cognitive resources for personalized service, and the scarcity of cognitive resources increases the degree of privacy disclosure; Emotional change in privacy decision is the result of many factors, not the result of privacy risk alone.

Originality/Discussion

This study provides a new perspective to explain the process of privacy decision-making, and a new approach to investigate the privacy paradox.

The exploration of a ‘model’ for understanding the contribution of emotion regulation to students learning. The role of academic emotions and sense of coherence

The present study is exploring a pathway connecting emotion regulation with academic progress. Specifically, the pattern through which emotion regulation is implicated in learning and academic progress through academic emotions and sense of coherence. This cross-sectional study involves of 406 undergraduate social science students recruited from a university in western Greece. Participants anonymously and voluntarily completed a number of self-report measures. The Emotion Regulation Questionnaire, the Sense of Coherence Scale, the Student Experience of Emotions Inventory and the Approaches to Learning and Studying Inventory, were used to measure emotion regulation, sense of coherence, academic emotional experiences and approaches to learning, respectively. Α four-stage model was tested with structural equation modelling techniques. In particular, the model examined associations between emotion regulation, sense of coherence, academic emotions, approaches to learning and academic progress. The analysis revealed pathways through which these associations appear to be maintained and driven by emotion regulation. Emotion regulation is associated with students’ academic emotions that in turn are linked with approaches to learning and academic progress. Both positive and negative emotions appear to play a role in enabling an adaptive approach to learning. Moreover, sense of coherence may serve as an important meta-cognitive factor enabling students to approach the learning process more effectively. The findings are discussed in the light of the recent literature.

An event-related potential investigation of distanced self-talk: Replication and comparison to detached reappraisal

Emotion regulation is critical for managing stress, but many regulatory strategies consume high levels of cognitive resources to implement, which are depleted under stress. This raises a conundrum: the tools we have to feel better may be ineffective when they are most needed. Recent event-related potential (ERP) research indicates that distanced self-talk (i.e., reflecting on one's experiences using non-first-person singular pronouns and one's name) reduces negative emotional reactivity without overtaxing cognitive resources. Here, we report the first direct replication of this work and extend it by examining how distanced self-talk compares to detached reappraisal, one of the most frequently studied regulatory techniques. Sixty-seven participants were randomly assigned to an emotion regulation picture task and instructed to reflect on the feelings they experienced in response to viewing negative emotional images using distanced self-talk or detached reappraisal while ERPs were measured. Directly replicating past findings, distanced self-talk led to a reduction in an affective arousal ERP, the late positive potential (LPP), without increasing stimulus preceding negativity (SPN), an ERP that reflects anticipatory and preparatory processing. These results further bolster support for distanced self-talk as a relatively effortless emotion regulation strategy. On the other hand, detached reappraisal was neither associated with the modulation of the LPP nor the SPN. Due to the failed replication of the reappraisal effect, a direct comparison between emotion regulation strategies was not conducted. Methodological limitations that may have contributed to the reappraisal failure and future directions for comparisons between emotion regulation strategies comparison are discussed.

At the heart of change: Differences in young offenders' HRV patterns after the delivery of the PSYCHOPATHY.COMP program

INTRODUCTION

Literature has pointed the need for intervention programs specifically tailored to target the treatment needs of young offenders, as well as the need to test the efficacy of such programs through physiological indexes of emotion regulation (e.g., heart rate variability; HRV), complementing self-reports typically used as outcome measures. The PSYCHOPATHY.COMP is a 20-session individual intervention program based on Compassion Focused Therapy aiming to reduce psychopathic traits and disruptive behavior among young offenders through the development of a compassionate motivation, while stimulating the soothing system as a strategy to improve emotion regulation. Previous research with young offenders has shown decreases in vagally mediated HRV (vmHRV) when the soothing system is activated. This physiological pattern seems to mirror threat-like responses that contrast with relaxed states.

METHODS

To test the efficacy of the PSYCHOPATHY.COMP, a clinical trial was implemented encompassing a treatment (n = 56) and a control group (n = 53). Treatment participants attended the PSYCHOPATHY.COMP, while controls received the Treatment As Usual (TAU) delivered in Portuguese juvenile detention facilities. HRV data was collected throughout a standardized procedure (encompassing resting, reactivity and recovery phases) specifically designed to trigger the soothing system. Participants were assessed at pre-treatment, post-treatment and 6-months follow-up.

RESULTS

Although treatment participants continued to process the soothing system as unpleasant (with decreased vmHRV), they seem to become able to adaptively recover from the stimuli without avoiding it or resorting to maladaptive coping strategies. The physiological pattern was in line with participants' decreases in difficulties in emotion regulation across the assessment periods. In contrast, controls seemed to have actively employed coping strategies associated with increases in vmHRV not only when the soothing system was triggered, but also when recovering from the stimuli. Congruently, for controls, increases in difficulties in emotion regulation were found, with increases in the lack of emotional clarity across the assessment periods.

DISCUSSION

Findings offer new evidence for the efficacy of the PSYCHOPATHY.COMP program in improving emotion regulation in young offenders, assessed through both self-report and physiological measures. Additionally, findings support the assessment of the autonomic balance as a treatment efficacy index in future research, targeting the rehabilitation of these youth.

The relationship between habitual use and real-time emotion regulation strategies in adolescents: Evidence from frontal EEG asymmetry

Past research on emotion regulation has shown that cognitive reappraisal is a healthier and more effective emotion regulation strategy than expressive suppression. However, there are few studies in this field that combine real-time emotion regulation with the use of habitual emotion regulation strategies to observe the patterns of brain activity, and fewer studies focusing on adolescents. Frontal electroencephalography (EEG) asymmetry reflects the difference between brain activation in left and right frontal areas and is widely viewed as an effective biomarker of emotional reactivity and regulation. The present study investigated the asymmetry of the frontal EEG activity during adolescents' emotional regulation, and explored its relationship with adolescents' habitual use of emotional regulation strategies. Habitual use of cognitive reappraisal and expressive suppression was measured with the emotion regulation questionnaire (ERQ). EEG was recorded from 54 adolescents (24 boys & 30 girls, M_age = 12.59), during the Reactivity and Regulation-Image Task. Results showed that adolescents who used cognitive reappraisal strategies more habitually exhibited greater left frontal asymmetry during real-time enhancement or reduction of negative emotions. In contrast, no significant correlation was found between habitual use of suppression and frontal alpha asymmetry. The results provide neurological evidence that, for adolescents, the use of habitual emotion regulation strategies may affect real-time emotion regulation, adolescents who use cognitive reappraisal more frequently are more capable or more prone to recruit appropriate brain regions in situations that need to regulate negative emotions. This reinforces the importance of the formation and use of correct emotion regulation habits for adolescents.

EEG microstate analysis of emotion regulation reveals no sequential processing of valence and emotional arousal

In electroencephalography (EEG), microstates are distributions of activity across the scalp that persist for several tens of milliseconds before changing into a different pattern. Microstate analysis is a way of utilizing EEG as both temporal and spatial imaging tool, but has rarely been applied to task-based data. This study aimed to conceptually replicate microstate findings of valence and emotional arousal processing and investigate the effects of emotion regulation on microstates, using data of an EEG paradigm with 107 healthy adults who actively viewed emotional pictures, cognitively detached from them, or suppressed facial reactions. Within the first 600 ms after stimulus onset only the comparison of viewing positive and negative pictures yielded significant results, caused by different electrodes depending on the microstate. Since the microstates associated with more and less emotionally arousing pictures did not differ, sequential processing could not be replicated. When extending the analysis to 2000 ms after stimulus onset, differences were exclusive to the comparison of viewing and detaching from negative pictures. Intriguingly, we observed the novel phenomenon of a microstate difference that could not be attributed to single electrodes. This suggests that microstate analysis can detect differences beyond those detected by event-related potential analysis.

HRV patterns associated with different affect regulation systems: Sex differences in adolescents

Evolutionary perspectives of human behavior propose the existence of three emotion regulation systems (i.e., threat, drive and soothing systems). An unbalanced functioning of the systems represents greater risk for emotion dysregulation and psychopathology. In recent years, heart rate variability (HRV) has been reported as an accurate index of emotion regulation, and although adolescence is characterized by multiple neurophysiological, psychological and social changes, there is no study exploring the HRV patterns of each emotion regulation system in this developmental stage. In Study 1, a standardized procedure (SP) aiming to elicit the three different systems was developed and validated by experts (n = 14) and community adolescents (n = 31). In study 2, differences in HRV patterns across the three emotion regulation systems and across sex, were investigated in a sample of community adolescents (n = 155; 70 males), aged between 14 and 18 years old. Results showed that the threat and drive systems were associated with decreases in HRV, while the soothing system was associated with decreased heart rate. Sex differences were found for the activation of the threat system: while males maintained a decreasing trend in HRV indexes, from resting to recovery, females did not show a decrease in HRV during the activation of this system. Overall, physiological correlates of each specific emotion regulation system corroborate the theoretical assumptions. Moreover, a SP able to trigger each system independently while measuring physiological data is now available and can be used in future research.

Development of emotion processing and regulation: Insights from event-related potentials and implications for internalizing disorders

Emotionally-salient stimuli receive selective attention and elicit complex neural responses that evolve considerably across development. Event-related potentials (ERPs) optimally capture the dynamics of emotion processing and regulation, with sensitivity to detect changes in magnitude, latency, and maximal location across development. In this selective qualitative review, we summarize evidence of developmental changes in neural reactivity to emotional stimuli and modulation of neural responses during emotion regulation indexed by ERPs across infancy, childhood, and adolescence. The cumulative ERP literature suggests the transition from childhood to adulthood is characterized by a gradual decrease in neural reactivity to emotional stimuli and increased efficiency in attentional allocation towards emotional stimuli. Some studies show sensitivity to emotional stimuli peaks in adolescence, but the evidence is mixed. While both early (<300 ms) and late (>300 ms) ERPs demonstrate sensitivity to emotional stimuli, emotional modulation is more consistently observed in relatively later ERPs across development. The literature additionally shows improvements in regulation abilities across development, though ERP research on developmental changes in emotion regulation is still relatively limited, highlighting a critical direction for future research. Finally, we briefly discuss changes in emotion-related ERPs relevant to the emergence of depression and anxiety. Findings from this review indicate that ERPs provide abundant information about the development of emotion processing and regulation, with potential clinical utility for detecting early-emerging vulnerabilities for internalizing forms of psychopathology.

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.

Influence of Perceptual and Conceptual Information on Fear Generalization: A Behavioral and Event-Related Potential Study

Learned fear can be generalized through both perceptual and conceptual information. This study investigated how perceptual and conceptual similarities influence this generalization process. Twenty-three healthy volunteers completed a fear-generalization test as brain activity was recorded in the form of event-related potentials (ERPs). Participants were exposed to a de novo fear acquisition paradigm with four categories of conditioned stimuli (CS): two conceptual cues (animals and furniture); and two perceptual cues (blue and purple shapes). Animals (C+) and purple shapes (P+) were paired with the unconditioned stimulus (US), whereas furniture (C-) and blue shapes (P-) never were. The generalized stimuli were thus blue animals (C+P+, determined danger), blue furniture (C-P+, perceptual danger), purple animals (C+P-, conceptual danger), and purple furniture (C-P-, determined safe). We found that perceptual cues elicited larger fear responses and shorter reaction times than did conceptual cues during fear acquisition. This suggests that a perceptually related pathway might evoke greater fear than a conceptually based route. During generalization, participants were more afraid of C+ exemplars than of C- exemplars. Furthermore, C+ trials elicited greater N400 amplitudes. Thus, participants appear able to use conceptually based cues to infer the value of the current stimuli. Additionally, compared with C+ exemplars, we found an enhanced late positive potential effect in response to C- exemplars, which seems to reflect a late inhibitory process and might index safety learning. These findings may offer new insights into the pathological mechanism of anxiety disorders.

Biological signatures of emotion regulation flexibility in children: Parenting context and links with child adjustment

Emotion regulation (ER) is a key facet of positive adjustment throughout the lifespan. Recent theoretical and empirical innovations suggest that current methods for assessing ER are limited, because they measure discrete strategy use instead of ER flexibility and are insensitive to ecologically valid social contexts that influence ER. This is particularly important for studying the impact of parenting on ER development during childhood. The current study (N = 93; 47 females; M_age = 6.98, SD = 1.12) examined child ER flexibility during a directed reappraisal task (DRT) with two parenting contexts: passive parent presence or active scaffolding. Two biological signatures of ER flexibility were measured: respiratory sinus arrhythmia (RSA), an index of physiological flexibility; and the late positive potential (LPP), an index of neurocognitive flexibility. Emotion regulation behavior was observed during a frustrating wait, and parents reported on child ER and adjustment. Greater ER flexibility indexed via the LPP and RSA both predicted observed ER during the frustrating wait, but only RSA predicted parent-reported trait ER and fewer adjustment problems. Emotion regulation flexibility indexed by the LPP was bolstered by parent presence and scaffolding of child ER during the DRT, but RSA measures were not sensitive to parenting context. Taken together, the results provide converging evidence for the conceptualization of ER in terms of physiological and neurocognitive flexibility in childhood. Furthermore, among school-aged children, while physiological flexibility broadly predicted parent-reported child adjustment, neurocognitive flexibility may be context-sensitive and predictive of concurrent observed ER.

Emotion regulation in adolescents: Influences of internal representations of relationships - An ERP study

Emotion regulation (ER) strategies can decrease the intensity or modify the experience of emotions. Deficits in emotion regulation are implicated in a wide range of psychopathologies. It is argued that interpersonal, socio-cognitive, and developmental variables play an important role in ER. This is the first study to explore the contribution of individual differences in internal representations of relationships (IRR) to neural correlates of ER in a sample of adolescents. Event related potentials of 53 adolescents (12 to 17 years old) were collected while performing an ER task. IRR was assessed with the social cognition and object relations scale (SCORS-G; Westen, 1995) coding of narratives from interviews. Results show that individual differences in IRR significantly predicted the modulation of emotional responses by expressive suppression in adolescents, accounting for 48% of the variance of changes in occipital late positive potentials (LPP). Thus, it appears that IRR are implicated in an individual's ability to regulate emotions. The clinical implications of the findings are discussed.

Deficient Emotional Self-Regulation in Children with Attention Deficit Hyperactivity Disorder: Mindfulness as a Useful Treatment Modality

OBJECTIVE

The aim of this study was to investigate the efficacy of a structured mindfulness group intervention program targeting deficient emotional self-regulation (DESR) in a sample of children with attention deficit hyperactivity disorder (ADHD).

METHOD

Seventy-two children aged 7 to 12 years with ADHD were randomized into 2 groups (mindfulness and control). The dysregulation profile was measured using the Child Behavior Checklist (CBCL) Attention/Anxiety-Depression/Aggression scales.

RESULTS

Children with ADHD who received mindfulness-based group therapy showed lower levels of DESR after treatment, with a reduction in CBCL dysregulation profile (F (1,63) = 4.81; p = 0.032). All ADHD symptoms showed a moderately significant positive correlation with DESR (p < 0.01). Children with combined-type showed higher levels of DESR than children with inattentive-type (p = 0.018); however, no statistically significant changes were observed in the combined-type after mindfulness treatment.

CONCLUSION

This study suggests that mindfulness in the form of structured group therapy might be clinically relevant in treating children with ADHD and thus make an impact on the overall clinical outcome, regardless of the ADHD subtype.

Impaired Frontoparietal Connectivity in Traumatic Individuals with Disorders of Consciousness: A Dynamic Brain Network Analysis

Recent advances in neuroimaging have demonstrated that patients with disorders of consciousness (DOC) may retain residual consciousness through activation of a complex functional brain network. However, an understanding of the hierarchy of residual consciousness and dynamic network connectivity in DOC patients is lacking. This study aimed to investigate residual consciousness and the dynamics of neural processing in DOC patients. We included 42 patients with DOC, categorized by aetiology. Event-related potentials combined with time-varying electroencephalography networks were used to probe affective consciousness in DOC and examine the related network mechanisms. The results showed an obvious frontal P3a component among patients in minimally conscious state (MCS), while a prominent N1 was observed in unresponsive wakefulness syndrome (UWS). No late positive potential (LPP) was detected in these patients. Next, we divided the results by aetiology. Patients with nontraumatic injury presented an obvious frontal P3a response compared to those with traumatic injury. With respect to the dynamic network mechanism, patients with UWS, both with and without trauma, exhibited impaired frontoparietal network connectivity during the middle to late emotion processing period (P3a and LPP). Surprisingly, unconscious post-traumatic patients had an evident deficit in top-down connectivity. This, it appears that early automatic sensory identification is preserved in UWS and that exogenous attention was preserved even in MCS. However, high-level cognitive abilities were severely attenuated in unconscious patients. We also speculate that reduced frontoparietal connectivity may be useful as a biomarker to distinguish patients in an MCS from those with UWS given the same aetiology.
