Is emotion regulation impacted by executive functions? An experimental study

The association between aspects of expressive suppression emotion regulation strategy and rumination traits: a network analysis approach

Expressive suppression is an abnormal emotion regulation strategy, and its relationship with rumination traits is unclear. In this study with 395 participants in China (33.9% female, Mean age = 21.22, SD = 2.11), we estimated the association between expressive suppression and rumination traits, using the Rumination Response Scale (RRS) and the Emotion Regulation Questionnaire (ERQ) respectively. Considering there may be complex correlations between different behavioral symptoms of expressive suppression ("Keeping emotions to myself", "Inhibiting positive emotion responses", "Controlling emotions by not expressing them", "Inhibiting negative emotion responses") and different subtypes of rumination traits, this study employed a symptom-based network analysis method to uncover the differential association between rumination traits and expressive suppression, and the key symptoms linking the two. The study found the S3 node (Controlling emotions by not expressing them) had significant positive correlations with symptom rumination, brooding, and reflective pondering. Among the network, the S3 node acts as a bridge between two variables. This suggests that interventions targeting the S3 symptom may improve rumination traits. The present study was a cross-sectional study with limitations in revealing the causal relationships between expression suppression and rumination traits. Future studies could employ longitudinal tracing methods to explore the relationship between them.

Effects of physical activity on anxiety levels in college students: mediating role of emotion regulation

Objectives

To explore the effects of physical activity on anxiety levels in college students, as well as to examine the mediating role of emotion regulation.

Methods

A convenience sample of 1,721 college students from Shanghai, Jiangsu, Shandong, Guangxi, and Hunan was used to conduct an evaluation and a survey through the Physical Activity Rating Scale (PARS-3), the Anxiety Self-Rating Scale (SAS), and the Emotion Regulation Scale (ERQ).

Results

College students' anxiety level, cognitive reappraisal, and expression inhibition scores were (44.72 ± 10.37), (30.16 ± 6.51), and (16.96 ± 4.99), respectively. There were significant grade and physical activity level differences in anxiety levels and cognitive reappraisal, and significant gender and physical activity level differences in expression inhibition among college students. Process model 4 mediated effect regression analysis showed that physical activity had a significant positive effect on cognitive reappraisal (R 2 = 0.14, β = 0.04, P < 0.001), and physical activity did not have a significant expression inhibition effect (R 2 = 0.17, β = 0.01, P = 0.27). Physical activity (β = -0.03, P = 0.012), cognitive reappraisal (β = -0.59, P < 0.001), and expression inhibition had a significant effect on (β = 0.57, P < 0.001) anxiety levels (R 2 = 0.37). In the model effect relationship, the direct and indirect effects of physical activity on anxiety levels were -0.028 and -0.019, respectively.

Conclusion

Physical activity has a significant negative effect on college students' anxiety levels. Cognitive reappraisal is a mediating variable for the effect of physical activity on anxiety levels. The higher the level of physical activity and the higher the intensity of the activity, the lower the level of anxiety.

The Impact of Virtual Reality Intervention on Emotion Regulation and Executive Functions in Autistic Children

Introduction: Autistic children may encounter difficulties in managing emotions and executive functions (EFs), which can contribute to mental and health challenges. Recognizing physical activities as a potential strategy for enhancing emotion regulation (ER), this study aims to investigate the efficacy of a virtual reality (VR)-based physical exercise program in improving ER and EFs among children with autism spectrum disorder (ASD). Materials and Methods: Forty boys diagnosed with ASD, aged 7 to 10 years, were randomly assigned to two groups: a VR intervention group (n = 20) and a control group (n = 20). The intervention group participated in a VR program, while the control group solely concentrated on engaging in sedentary and inactive video gaming. EFs were evaluated through the utilization of both the flanker task and the Wisconsin card sorting task, both administered initially at baseline and subsequently after an 8-week interval. In addition, the parents of the children completed the Emotion Regulation Checklist to evaluate their ER skills. Results: According to the results, a significant difference was observed between the two groups in terms of EFs and the ability to regulate emotion (P < 0.05). The intervention group demonstrated a notable improvement in ER skills and exhibited superior executive functioning abilities compared with the control group. Conclusion: It appears that VR exercises can serve as a preliminary trial to enhance EFs and ER in children with autism. In addition, they may prove effective as complementary interventions to traditional educational strategies in preventing future challenges associated with ASD.

Development of Playfulness in Children with Low Executive Functions: The Role of Parental Playfulness and Parental Playtime with Their Child

Children with low executive functions (EFs) are described as having lower levels of playfulness, the quality of children's play, compared to children with EFs within the normal range. However, how playfulness in children with low EFs develops over time remains unclear. Additionally, little is known about how parental playfulness and parental playtime with their child affect these developmental trajectories in children with low EFs. To address these research gaps, we measured playfulness in 62 children with low EFs and 62 children with EFs within the normal range aged 3 to 6 years at three time points over 2 years. We used the Children's Playfulness Scale, which captures multi-informant perspectives from parents and teachers. Moreover, the parents of children with low EFs reported their own playfulness and their playtime with their children at T1. Repeated-measures hierarchical linear models indicated significantly lower levels of playfulness in the children with low EFs than in the controls, with no significant changes observed over 2 years in either group. In the children with low EFs, we found a significant positive relationship between parental playfulness at T1 and children's playfulness 2 years later but a significant negative relationship between parental playtime at T1 and children's playfulness 2 years later. These results prompt a broad discussion on potential implications for the enhancement of playfulness in children with low EFs within the family environment.

Assessing Frontal Lobe Function on Verbal Fluency and Emotion Recall in Autism Spectrum Disorder by fNIRS

This study applied the functional near-infrared spectroscopy (fNIRS) to investigate frontal activity in autism when performing verbal fluency test and emotion recall task. We recruited 32 autistic adults without intellectual disability and 30 typically-developing controls (TDC). Prefrontal hemodynamic changes were evaluated by fNIRS when the participants performed the verbal fluency test and emotion recall task. fNIRS signals in the prefrontal cortex were compared between autism and TDC. Compared to TDC, autistic adults showed comparable performance on the verbal fluency test but exhibited lower frontal activity on the vegetable category. In the verbal fluency test, left frontal activity in TDC significantly increased in the vegetable category (vs. fruit category). In the emotion recall task, left frontal activity increased significantly in TDC when recalling emotional (vs. neutral) events. This increase of left frontal activity on the more difficult works was not found in autism. Similarly, brain activities were related to test performance only in TDC but not in autism. In addition, more severe social deficits were associated with lower frontal activity when recalling emotional events, independent of autism diagnosis. Findings suggested reduced frontal activity in autism, as compared to TDC, when performing verbal fluency tests. The reduction of left frontal activation in verbal fluency test and emotion recall tasks might reflect on the social deficits of the individual. The fNIRS may potentially be applied in assessing frontal lobe function in autism and social deficits in general population. Trial registration number: NCT04010409.

The mediators for the link between autism and real-world executive functions in adolescence and young adulthood

LAY ABSTRACT

Childhood factors that predict real-world executive function in autism spectrum disorder during the transition into adulthood are largely unknown. This study aimed to identify the predictors for the behavioral and cognitive aspects of real-world executive function in late adolescent and young adult autistic populations. We followed up 289 autistic youth (mean age 11.6 years) and 203 non-autistic controls (10.7 years) to their ages of 16.9 and 15.8, respectively. The Behavior Rating Inventory of Executive Function scale was used to measure the real-world executive function at late adolescence and young adulthood at follow-up. Potential predictors such as autistic symptoms, inattention or hyperactivity symptoms, peer relationship, emotional symptoms, and parenting styles were assessed in childhood at first enrollment. The results showed that childhood inattention, withdrawn behaviors, social communication difficulties, and child-reported emotion and inattention/hyperactivity may predict real-world lower executive function in late adolescence and young adults with autism. When separating executive function into behavioral and cognitive aspects, we found that oppositional behaviors and peer problems were specific predictors for behavioral regulation and cognitive function, respectively. Our findings suggested that treating common predictors in childhood, such as inattention, may potentially improve real-world executive function in autism during the transition into adulthood.

Efficacy of the use of video games on mood, anxiety and depression in stroke patients: preliminary findings of a randomised controlled trial

BACKGROUND

In the different published studies, there is no consensus on the efficacy of virtual reality as an adjuvant treatment of mood states.

AIM

The aim of this study is to evaluate the impact of no immersive virtual reality with the Nintendo Switch device in rehabilitation treatment on mood, anxiety and depression in stroke patients admitted to neurorehabilitation units.

METHODS

Fifty-eight patients admitted to neurorehabilitation units underwent a 1:3 multicentre randomised clinical trial. The intervention group consisted of 17 patients and the control group of 41 patients. The intervention group performed 6 virtual reality sessions together with the conventional treatment, and the control group performed only the conventional rehabilitation sessions. Primary and secondary clinical outcomes were measured before and six weeks after the intervention.

RESULTS

Comparing the intervention group and control group, the anxiety levels of the intervention group decreased compared to the results observed in the control group (p = 0.01), as did the dependence of the intervention group (0.015). On the other hand, the results obtained after the intervention by the control group for anxiety (0.479) and depression (0.292) were not statistically significant.

CONCLUSION

Rehabilitation VR used as an adjuvant treatment to conventional treatment has a beneficial impact on the neurological status and state of anxiety of stroke patients admitted to neurorehabilitation units.

The role of engagement and arousal in emotion regulation: an EEG study

Cognitive reappraisal and expressive suppression are well-studied strategies of emotion regulation (ER). However, the results on their physiological basis are controversial. While in some studies, ER was accompanied by the inhibition of the nervous system, others suggested that ER even might increase arousal and engagement. We calculated the inter-subject correlation (ISC) and indices of engagement, valence and arousal of EEG during suppression, reappraisal, or natural watching of neutral and negative videos. First, both suppression and reappraisal provoked a higher ISC in comparison with watching negative or neutral videos. We consider this as a marker of engagement to the task and feedback processing required for ER. Second, the engagement index was lower during ER compared to watching negative videos in central electrodes, whereas both strategies provoked a higher engagement in frontal electrodes. Third, the arousal index of EEG was higher during all negative conditions; therefore, regulation required a certain level of arousal. In summary, different EEG measures seem to be sensitive to different aspects of ER.

Household Income and Early Adolescents' Executive Function: The Different Roles of Perceived Discrimination and Shift-and-Persist

Household income predicts early adolescents' cognitive development. However, the mechanism underlying this association and protective factors are unclear. This study assessed one-year longitudinal data to examine whether perceived discrimination mediated the association between household income and executive function and the moderating role of shift-and-persist. 344 early adolescents in rural China were included in the study (mean = 10.88 years, SD = 1.32 years, girls: 51.74%). The latent variable model revealed that household income predicted early adolescents' cognitive flexibility and working memory in the subsequent year through perceived discrimination. Shift-and-persist moderated the negative effects of perceived discrimination on cognitive flexibility: perceived discrimination impeded cognitive flexibility only among early adolescents with low shift-and-persist. The findings highlight perceived discrimination in the relation between household income and early adolescents' executive function and underscore the protective role of shift-and-persist.

Differential effects of mindfulness meditation and cognitive training on cool and hot inhibitory control in children and adolescents

Inhibitory control (IC) can occur either in a neutral context (cool) or in social contexts involving emotions (hot). Cool and hot IC have specific developmental trajectories; cool IC develops linearly from childhood to adulthood, whereas hot IC follows a quadratic trajectory. Some activities can improve the IC, such as cognitive training (CT) and mindfulness meditation (MM). The aim of our study was to compare the effects of 5 weeks of computerized MM versus CT on IC performance in 66 children (9-10 years old) and 63 adolescents (16-17 years old) by specifically analyzing cool and hot dimensions in the same participants and from a developmental perspective. We fit a linear mixed-effect model on the Stroop interference score with time (pretest vs. posttest) and type of conflict (cool vs. hot) as within-participant factors and intervention group (CT vs. MM) and age group (child vs. adolescent) as between-participant factors. The findings revealed that children but not adolescents benefitted from interventions. More specifically, CT improved cool IC but not hot IC, whereas MM practice improved hot IC but not cool IC. This study supports the benefits of MM at a young age. Theoretical issues linking MM programs to emotional competence grounded in hot IC skills are considered in academic settings.

Relationship between adult attachment and cognitive emotional regulation style in women and men

Cognitive emotion regulation (CER) strategies are useful in evaluating the risk of developing emotional disorders and that they may define subjects' styles. This study aims to explore the extent to which specific styles of CER strategies relate to the anxious and avoidant attachment dimensions in adults and whether such relationships operate similarly for women and men. Two hundred and fifteen adults (between 22 and 67 years old) completed the Spanish versions of the Cognitive Emotion Regulation Questionnaire and the Experiences in Close Relationships instrument. Cluster analysis, ANOVA and Student's t-test were used. Our results show that women and men can be successfully classified into two CER clusters (Protective and Vulnerable), distinguished by the higher use in the protective cluster of the CER strategies considered most adaptive and complex (Acceptance, Positive Refocusing, Refocus on Planning, Positive Reappraisal, and Putting into Perspective). However, only in women were the anxious and avoidant attachment dimensions significantly associated with CER style. In conclusion, from a clinical and interpersonal perspective, it is interesting to be able to predict the belonging to a Protective or Vulnerable coping style by analysing the CER strategies and to know their relationship with the adult affective system.

The influence of bilingual experience on executive function under emotional interference: Evidence from the N1 component

The influence of bilingual education and experience on an individual’s information-processing ability has recently been a hot issue in international studies. Previous studies have found that bilingual experience affects executive function, but the results remain controversial. Executive function refers to the conscious control of purposeful behavior. It is responsible for processing high-level action controls, including such sub-functions as inhibitory control, cognitive switching, and working memory updating. Emotion, as an essential factor in daily life, also has a complex interaction with executive function. This paper explores whether the bilingual cognitive advantage effect can continue in the more complex conditions of emotional interference. To investigate the specific electrophysiological characteristics of the participants at different stages of cognitive processing, we used a combination of the behavioral and ERP experiments in which the positive, neutral, and negative emotional stimuli were selected as emotional interference conditions and the emotional Simon paradigm, the cognitive switching of emotion paradigm, and the emotional N-back paradigm was adopted. The results show that the main effect of the N1 component amplitude is significant. Specifically, the amplitude of the N1 component in the proficient bilinguals is significantly smaller than that of the non-proficient bilinguals, while the main effects of other component groups are not significant, indicating that under the condition of emotional interference, the influence of bilingual experience on executive function only exists in the early attention stage and that the bilingual experience can improve the individual’s attentional control and speed up attention processing in the early attention stage.
