Psychological Predictors of Attitude toward Integrated Arts Education among Chinese College Students Majoring in the Arts.

This study investigated the psychological factors related to the attitudes of Chinese arts college students toward integrated arts education. It also examined predictive models incorporating psychological variables, demographic profiles, and art education-related characteristics to offer valuable insights for future research and art education practices. The sample comprised 303 Chinese college students majoring in arts and aged 18-22 years. The predictive models were examined using stepwise regression and decision tree analyses. The results indicated positive correlations between attitudes toward integrated arts education and several psychological variables, including extraversion, openness, conscientiousness, agreeableness, the Behavioral Inhibition System (BIS), hardiness, creativity, self-efficacy, and purpose orientation for personal growth. Neuroticism and the Behavioral Activation System (BAS) were negatively correlated with attitudes toward integrated arts education. Further, extraversion accounted for the greatest variance in attitudes toward integrated arts education. Extraversion, self-efficacy, purpose orientation for personal growth, BIS, and commitment accounted for approximately 38.3% of the variance. The decision tree model, predicting the attitudes of college students majoring in the arts toward integrated arts education, included extraversion, self-efficacy, teaching experience in their major, and academic year. This study contributes to a better understanding of the psychological and educational factors that shape the attitudes of Chinese arts students toward integrated arts education and provides a predictive framework that can inform future research and educational practices.

Increased behavioural inhibition and decreased behavioural activation in whiplash‐associated disorders: Associations with health outcomes

AbstractBackgroundMotivation can be investigated with the BIS (Behavioural Inhibition System)/BAS (Behavioural Activation System) scale. BAS regulates the motivation to approach goal‐oriented outcomes, particularly rewarding stimuli and situations, while BIS regulates escape and avoidance of unpleasant outcomes. Chronic whiplash‐associated disorders (WAD) is a heterogenous pain condition with known alterations in motivated behaviour. The study aimed (1) to investigate the relationship between BIS/BAS, and pain and disability with quality of life and psychological measures in chronic WAD; (2) to determine if BIS and/or BAS mediate the relationships between pain, disability, and psychological symptoms and quality of life.Methods254 chronic WAD patients participated in the study. Outcome measures were assessed using self‐report questionnaires. BIS/BAS scores were compared to published normative data. Differences in health outcomes for participants within/outside normative 95% confidence intervals were compared and correlations with health measures tested. Mediation models explored bi‐directional associations between stress, anxiety, depression, post‐traumatic stress severity, pain catastrophizing, and quality of life with pain and disability.ResultsParticipants who exceeded normative 95% confidence intervals for BIS demonstrated higher scores for pain interference, disability and all mental health measures. No mediating role of BIS/BAS on the relation between pain and disability with quality of life and health outcomes could be confirmed.ConclusionsA comparatively large proportion of the sample exceeded the 95% confidence interval for BIS and BAS scores with associations of these scores with health outcomes, but altered motivation to approach goal‐oriented outcomes appears to play only a subordinate role in chronic WAD.Significance statementIn line with current theories, we found a large proportion (30%–50%) of patients with whiplash‐associated disorders (WAD) showing signs of altered function in the Behavioural Inhibition System (BIS) and Behavioural Activation System (BAS) suggesting altered reward processing and motivation in these patients. While such altered functions showed associations with pain interference, disability and all mental health measures, reward processing could no be demonstrated as a pathogenetically relevant factor in chronic WAD patients.

From individual motivation to substance use initiation: A longitudinal cohort study assessing the associations between reward sensitivity and subsequent risk of substance use initiation among US adolescents

BackgroundSubstance use in youth remains a pressing problem in the United States. Existing studies have shown the importance of neuropathways responsible for affective response and reward motivation in adolescents’ substance use initiation and maintenance. However, limited observational studies have explored the relationship between aspects of behavioral motivation traits and the likelihood of substance use initiation in adolescents. In this prospective cohort study, we assessed the associations between behavioral motivation traits based on the Behavioral Inhibition and Approach Systems (BIS-BAS) Scale and substance use initiation using data from the Adolescent Brain Cognitive Development (ABCD) study. MethodIn the 9216 eligible sample population, we assessed the associations between mean Behavioral Inhibition System (BIS) / Behavioral Approach System (BAS) scores measured at year 2 of the ABCD study and substance use initiation at year 3 of the ABCD study using multivariable logistic regressions adjusting for ABCD study site, sampling weights, as well as sociodemographic characteristics. ResultsWe found that higher BIS mean score was associated with higher odds of initiating substance use at year 3 (AOR=1.20, 95 % CI: 1.03, 1.40). Out of three BAS measure categories, only BAS Fun-seeking mean score was positively associated with higher odds of initiating substance use at year 3 (AOR=1.23, 95 % CI: 1.07, 1.43). ConclusionOur study showed that inhibitory and fun-seeking behavioral tendencies are associated with an increased likelihood of substance use initiation in adolescents. Our findings suggest a potential pathway linking emotional traits to early substance initiation in adolescents.

Sensitivity to rewards and punishments in karate athletes: an examination of the temperamental characteristics and profile of karate competitors according to the revised reinforcement sensitivity theory

BackgroundThe revised Reinforcement Sensitivity Theory (rRST) assumes the existence of three systems controlling motivation and behavior: the behavioral activation system (BAS), the behavioral inhibition system (BIS), and the fight-flight-freeze system (FFFS). This study aims to examine for the first time the features of BAS, BIS, and FFFS among karate players in comparison with athletes representing other sports disciplines (physical education students) and physically inactive people. The specific configuration of temperament traits and profiles characterizing karate players will also be found.MethodsThe cross-sectional study was performed among male karate athletes and control groups (physically active and inactive men). The study used the modified Reinforcement Sensitivity Questionnaire (rRSQ) to measure BAS, BIS, and FFFS.ResultsThe ANOVA showed that both karate competitors KS and KK scored significantly higher in BAS than the sample of PI participants. In addition, KK athletes scored significantly lower in Freeze than in PI and KS groups. Research also suggests that KK athletes presented significantly lower overall scores in FFFS than PI individuals. Furthermore, the results of K-means cluster analysis indicated the existence of two distinct patterns of temperamental traits: (1) Cluster 1 suggests avoidance tendencies (high Flight and Freeze, and low BAS, BIS, and Fight levels); while (2) the Cluster 2 describes approach tendencies (high BIS, BAS and Fight scores, and low levels of Flight and Freeze). Significantly more KK athletes were included in Cluster 2 than in Cluster 1, compared to PI, PA, and KS samples.ConclusionsThe research indicates that individuals engaged in karate, particularly those practicing Kyokushin karate, tend to exhibit a heightened sensitivity to rewards (high BAS). This finding holds significance for coaches and sports instructors, suggesting that motivating karate athletes through incentives is more effective, while the use of punishment should be minimized during training. Additionally, the study proposes that the practice of Kyokushin karate has the potential to significantly diminish the freezing response in threatening situations and enhance overall fear management by reducing levels of the Fight-Flight-Freeze System (FFFS). Consequently, the Kyokushin karate style may be considered more advantageous than the Karate Shotokan (KS) style in these aspects, despite both styles contributing to the improvement of BAS. Given that a higher BAS is linked to positive emotions, optimism, and happiness, karate training emerges as a form of health intervention, acting as a preventive measure against mental disorders and promoting overall well-being.

Distinct patterns of hippocampal subfieldvolumes predict coping strategies, emotion regulation, and impulsivity in healthy adults.

Recent studies have suggested that the hippocampus (HC) is involved in cognitive and behavioral functions beyond memory.We aimed to investigate how the volume of each subfield of the HC is associated with distinct patterns of coping strategies, emotion regulation, and impulsivity in a healthy population. We studied a total of 218 healthy subjects using the Leipzig mind-brain-body dataset. Participants were assessed for coping strategies, emotion regulation, and impulsivity using the Cognitive Emotion Regulation Questionnaire(CERQ), Coping Orientations to Problems Experienced (COPE), Impulsive Behavior Scale (UPPS), and Behavioral Activation and Inhibition System (BAS/BIS). The associations between HC subfield volumes including CA1, CA2/3, CA4/DG, SR-SL-SM, and subiculum, and behavioral scores were examined using multiple linear regression models adjusted for possible confounders, including age, sex, years of education, handedness, total intracranial volume (ICV), and HC volume. The use of emotional support, venting, and positive reframing coping strategies were significantly and positively correlated with total, total right, and total left HC volumes. Venting was significantly associated with CA1 after adjusting for age, sex, handedness, and education (P=0.001, B = 0.265, P-FDR = 0.005).No significant association was observed between CERQ subscales and HC subfieldvolumesafter controlling for confounders and multiple analyses. However,sensation-seeking subscale of the UPPS-P was positively correlated with total and right CA2-CA3 volumes after adjustments for age, sex, handedness, ICV, and HC volumes(P=0.002, B = 0.266, P-FDR = 0.035).BAS and BIS subscales did not showsignificant relationshipwith HC subfield volumes. Patterns ofHC subfieldsvolumes are associated with copingstrategies, impulsivity, and emotion regulation.In particular, using emotional support, positive reframing, venting, and sensation seeking aresignificantly associated with certain HC subfield volumes.These findings suggest that the hippocampus may play a crucial role in modulating emotional responses and behavioral adaptations, offering potential targets for therapeutic interventions.

Monetary reward enhances response inhibition processes manifested in No-go P3

This study investigated the impact of motivational valence on No-go P3 and N2 by incorporating monetary rewards based on response outcomes. We also investigated how personality differences in terms of the behavioral inhibition system (BIS) and behavioral approach system (BAS) influenced No-go N2 and No-go P3. Twenty-eight participants performed Go/No-go tasks (80 % Go and 20 % No-go) under two conditions. In the reward condition, each correct-rejection trial for the No-go stimulus was rewarded with 10 yen (∼6 cents), whereas in the neutral condition, neither monetary rewards nor punishments were contingent on response outcomes. Individual responsiveness to punishment and rewards was evaluated using the BIS and BAS scales. The error rate was significantly lower in the reward condition than in the neutral condition. P3 amplitude for correct-rejection trials (i.e., preceding erroneous muscular activity on the wrong hand) was larger in the reward condition than in the neutral condition; however, N2 amplitudes did not differ between the two conditions. These results suggest that monetary rewards may enhance motor inhibition control. Individuals with a higher BIS score exhibited a larger No-go N2 for correct-rejection in the neutral condition. We conclude that No-go N2 amplitude is modulated by avoidance motivation.

Roles of empathy in altruistic cooperation in adults with and without autism spectrum disorder

BackgroundAltruistic cooperation (AC) is essential in human social interactions. Previous studies have investigated AC-related behavior in children with autism spectrum disorder (ASD), revealing that there is considerable individual variability in the behavior. However, this issue is still largely unexplored especially in the adult population. AimsTo investigate individual differences in AC-related behavior, we conducted the resource allocation task (RAT) and modified version of the ultimatum game (mUG) among adults with and without ASD. Methods and proceduresThe study employed a cross-sectional design, involving 27 adults with ASD (mean age 29.1 ± 4.3 years; three females) and 27 adults with typical development (TD) (mean age 25.8 ± 6.7 years; two females), who completed the RAT and mUG tasks. Beyond clinical characteristics, we assessed three primary psychological metrics: the interpersonal reactivity index (IRI), Barratt impulsiveness scale, and the behavioral inhibition and activation systems. Outcomes and resultsNo significant differences were observed in the proportions of participants with high AC when assessed by RAT (p = 0.15) and mUG (p = 0.59) between the TD and ASD groups. Participants with high AC from the RAT demonstrated higher perspective-taking scores on the IRI than those with low AC within both the TD (p = 0.04) and ASD groups (p = 0.03). In the TD group, high AC individuals also scored higher on the IRI's fantasy subscale as per the mUG (p = 0.03); however, this trend was not present in the ASD group. Conclusions and implicationsThe present findings indicate that empathy plays an important role in individual differences in AC-related behavior among adults with and without ASD, although the role could be different depending on the types of AC-related behavior between TD and ASD populations.

Decreased Serum Cocaine- and Amphetamine-Regulated Transcript Level in Internet Gaming Disorder.

Vulnerability to internet gaming disorder (IGD) has increased as internet gaming continues to grow. Cocaine- and amphetamine-regulated transcript (CART) is a hormone that plays a role in reward, anxiety, and stress. The purpose of this study was to identify the role of CART in the pathophysiology of IGD. The serum CART levels were measured by enzyme-linked immunosorbent assay, and the associations of the serum CART level with psychological variables were analyzed in patients with IGD (n=31) and healthy controls (HC) (n=42). The serum CART level was significantly lower in the IGD than HC group. The IGD group scored significantly higher than the HC group on the psychological domains of depression, anxiety, the reward response in the Behavioral Activation System and Behavioral Inhibition System. There were no significant correlations between serum CART level and other psychological variables in the IGD group. Our results indicate that a decrease in the expression of the serum CART level is associated with the vulnerability of developing IGD. This study supports the possibility that CART is a biomarker in the pathophysiology of IGD.

Digital consumerism in times of crisis: exploring the shift in online shopping behaviour

PurposeThis research delves into consumer online shopping behaviour during the different phases of the COVID-19 pandemic, utilising the Theory of Planned Behaviour and the Behavioural Inhibition System.Design/methodology/approachA unique and comprehensive repeated cross-sectional methodology was meticulously employed, capturing the nuances of consumer online shopping behaviour across three distinct phases of the pandemic: the initial phase following the outbreak of COVID-19, the transition phase marked by the relaxation of restrictions, and the adaptation phase as society moved towards a new normal. The study involved a sample of 1,155 participants. Structural equation modelling was used to analyse the effects of behavioural attitudes, subjective norms, perceived behavioural control, and the moderating role of pandemic-induced consumer anxiety on online purchase intention.FindingsThe impact of behavioural attitudes on online purchase intentions increased continuously from the initial phase to the adaptation phase. In contrast, the influence of subjective norms on online shopping intentions gradually declined over the same period. During the early stages of the pandemic, consumer anxiety amplified the influence of personal attitudes towards online shopping while diminishing the impact of social pressures on the same behaviour.Originality/valueThis study’s originality lies in its nuanced analysis of how online purchase intentions evolved across different stages of the COVID-19 pandemic, integrating insights from both the Theory of Planned Behaviour and the Behavioural Inhibition System. The study offers a comprehensive understanding of the shifts in consumer behaviour over time. It enables more strategic and proactive marketing tactics in a changing environment.

Parent‐reported problematic lying tendencies and BIS/BAS activity as predictors of children's antisocial lie‐telling

AbstractThe current study examined whether age and parental reports of children's problematic lying, behavioural inhibition system (BIS) activity, and reward responsiveness predicted children's antisocial lie‐telling. Children from mostly middle and upper‐class Canadian families (ages 3–12, M = 6.23, SD = 2.52) participated in a modified Temptation Resistance Paradigm (TRP), where they were given opportunities to tell a self‐protective lie (to conceal a transgression) and an instrumental lie (to obtain a reward). Parents completed measures of their children's problematic lying tendencies, BIS activity, and reward responsiveness. Age and parent‐reported problematic lying and BIS activity were significant predictors of lie‐telling behaviour in the TRP. Instrumental liars were younger than dual liars (those who told both types of lies) and truth‐tellers. Truth‐tellers had lower parent‐reported problematic lying than instrumental and dual liars but not self‐protective liars. Dual liars had lower parent‐reported BIS activity than truth‐tellers; there were no differences among truth‐tellers, self‐protective liars, and instrumental liars. This study contributes to our understanding of the role of temperamental factors in children's lie‐telling propensity and the predictive utility of parent‐reported predictors for children's antisocial lie‐telling propensity. Our findings indicate that parents can identify and potentially address their children's problematic lying using their knowledge about their children's temperamental traits.

The relationship between boredom proneness, the behavioral inhibition system, and anxiety in college students: variable-centered and person-centered analytic approaches.

To explore the relationship among boredom proneness, the behavioral inhibition system, and anxiety among college students based on variable-centered and person-centered analytic approaches. A questionnaire survey was conducted on 1,102 college students from a university in Hebei Province using the Boredom Proneness Questionnaire (BPQ) for College Students, the Behavioral Inhibition System Scale (BIS), and the General Anxiety Disorder-7 scale (GAD-7). The results reveal that boredom proneness was negatively correlated with scores on the behavioral inhibition system (r = -0.100, p < 0.01), and positively correlated with anxiety (r = 0.457, p < 0.001), while the behavioral inhibition system was positively correlated with anxiety (r = 0.086, p < 0.01). In the variable-centered analyses study, it was found that the behavioral inhibition system partially mediated the association between boredom proneness and anxiety. In the person-centered analyses study, three subtypes were identified: the high boredom-low inhibition group (9.35%), the moderate boredom-inhibition group (66.70%), and the low boredom-high inhibition group (23.95%). Individuals in these subtypes showed significant differences in anxiety scores (F = 4.538, p < 0.05), with the low boredom-high inhibition group scoring the highest. The results showed that the behavioral inhibition system partially mediates the relationship between boredom proneness and anxiety in college students; boredom proneness and the behavioral inhibition system exhibit group heterogeneity, with distinct classification features closely related to anxiety.

Big Five personality traits, BIS/BAS dimensions and meteoropathy: a mediation model

BackgroundThe main goal of this cross-sectional study was to assess the relationship between Big Five personality traits and meteor-opathy and the role of the behavioural activation system (BAS) and the behavioural inhibition system (BIS) as mediators in this relationship.Participants and procedureThe sample consisted of 1,336 women and men gathered via the online recruitment platform from the general population. The participants’ ages ranged from 18 to 76 years (M = 29.52, SD = 11.67). The Polish version of the Ten Item Personality Inventory was used to assess Big Five personality traits. The BIS and BAS were diagnosed using the Polish version of the original BIS/BAS scales. Meteoropathy was assessed using the Polish adaptation of the METEO-Q questionnaire.ResultsMeteoropathy correlated negatively with emotional stability and positively with the BIS level and BAS Reward Responsive-ness. BIS negatively correlated with emotional stability. The correlations between meteoropathy and other personality vari-ables were nonsignificant. The analysis indicated a significant indirect relationship between emotional stability and meteor-opathy through BIS. We demonstrated the importance of neuroticism (low emotional stability) and the BIS dimension for the development of meteoropathy symptoms.ConclusionsNeuroticism and the BIS dimension were important for the development of meteoropathy symptoms. The results may be helpful in assessing the risk of developing meteoropathy in a healthy population.

Frontal alpha asymmetries and behavioral immune system: moderating role of behavioral inhibition system

Background and purpose: Behavioral immune system is a cluster of psychological mechanisms enabling detection and avoidance of pathogens in one’s immediate environment. Its presumed activation has been implicated in myriads of psychological phenomena, stemming from pathogen related disgust to more complex behaviors, such as mate choice and xenophobic cognitions. However, little is known about its biological underpinnings. The aim of this preliminary study was twofold: 1) to explore the role of another neuropsychological system governing avoidant motivations, the behavioral inhibition system, in pathogen-induced disgust and 2) to determine if frontal hemispheric asymmetries (a neural correlate of avoidant motivations) might serve as indicators of behavioral immune system activation. Materials and methods: 62 participants completed the Behavioral inhibition scale. Based on their z-scores, two extreme groups were formed: high (n=9) and low behavioral inhibition (n=9) group. After the baseline EEG recordings, participants were exposed to a set of neutral stimuli, followed by a set of pathogen disgust inducing stimuli. The frontal asymmetry (FAA) indexes (lnR-LnL) were calculated within both low (8-10 Hz) and high (11-13 Hz) alpha frequency bands on analogue pairs of frontal electrodes. Results: There were no baseline FAA differences between groups. However, compared to low behavioral inhibition group, high behavioral inhibition group showed larger shifts in FAA on frontopolar locations while watching the pathogen related disgust-inducing stimuli, as compared to neutral photographs. Conclusions: This pattern of FAA shifts suggests that high behavioral inhibition individuals attend to pathogen threat related cues more readily, i.e., have a more reactive behavioral immune system. With this preliminary study we are proposing a new line of research in order to determine if there is evidence of a calibrated response in terms of interplay between one’s immune status and pathogen treat related neural reactivity.

Measuring Pain-related Behavioral Inhibition and Behavioral Activation System Responses: Further Validity Evidence for the Pain Responses Scale.

The Pain Responses Scale and its Short Form (PRS-SF) were recently developed to assess the affective, behavioral, and cognitive responses to pain based on the behavioral inhibition system (BIS) and behavioral activation system (BAS) model of chronic pain. The purpose of this study was to provide additional tests of the psychometric properties of the PRS-SF in a new sample of individuals with chronic pain. A sample of Spanish adults (N = 190) with chronic non-cancer pain completed a translated version of the PRS-SF and a battery of questionnaires measuring validity criteria hypothesized the be associated with BIS and BAS activation, including measures of sensitivity to punishment, sensitivity to reward, pain intensity, pain interference, catastrophizing, and pain acceptance. Confirmatory factor analysis supported a 4-factor structure for the PRS-SF assessing despondent, escape, approach, and relaxation responses (S-B χ 2 [5] = 1.49, Comparative Fit Index = 0.99, Non-Normed Fit Index = 0.99, root-mean-square error of approximation = 0.051, Akaike Information Criterion = 4113.66), with marginal internal consistency for 1 scale (relaxation) and adequate to good internal consistency for the others. The pattern of associations found between the PRS-SF Scale scores and the validity criterion supports the validity of the instrument. The results provide additional support for the validity of the 4 PRS-SF Scale scores, and the reliability of 3 of the scales. If these findings are replicated in future research, investigators may wish to administer more items from the original Relaxation Scale when assessing this domain to ensure adequate reliability for this scale. The other items from the PRS-SF assessing despondent, escape, and approach responses appear to provide at least adequate reliability. When used in this way, the PRS-SF may be used to measure BIS and BAS responses to pain to: (1) provide further tests of the BIS-BAS model of chronic pain and/or (2) understand the potential mediating effects of BIS and BAS responses on the effects of psychological pain treatments to help determine which specific responses are most responsible for the benefits of treatment, and, therefore, which responses should be specifically targeted to enhance treatment response.

The prevalence and possible risk factors of gaming disorder among adolescents in China.

Nowadays, moderate gaming behaviors can be a pleasant and relaxing experiences among adolescents. However, excessive gaming behavior may lead to gaming disorder (GD) that disruption of normal daily life. Understanding the possible risk factors of this emerging problem would help to suggest effective at preventing and intervening. This study aimed to investigate the prevalence of GD and analyze its possible risk factors that adolescents with GD. Data were collected between October 2020 and January 2021. In total, a sample of 7901 students (4080 (52%) boys, 3742 (48%) girls; aged 12-18 years) completed questionnaires regarding the Gaming-Related Behaviors Survey, Gaming Disorder Symptom Questionnaire-21 (GDSQ-21); Behavioral Inhibition System and Behavioral Activation System Scale (BIS/BAS Scale); Emotion Regulation Questionnaire (ERQ); Short-form Egna Minnenav Barndoms Uppfostran for Chinese (s-EMBU-C); and Adolescent Self-Rating Life Events Checklist (ASLEC). The prevalence of GD was 2.27% in this adolescent sample. The GD gamers were a little bit older (i.e., a higher proportion of senior grades), more boys, with more gaming hours per week in the last 12 months, with more reward responsiveness, maternal rejecting and occurrence of negative life events (e.g., interpersonal relationships, being punished and bereavement factors). These possible risk factors may influence the onset of GD. Future research in clinical, public health, education and other fields should focus on these aspects for provide target prevention and early intervention strategies.

An evaluation of the behavioural inhibition system and behavioural activation system (BIS-BAS) model of pain in athletes

ABSTRACT This study examined coping and pain responses using a behavioural inhibition (BIS) – behavioural activation (BAS) framework in 489 student athletes (M(age) = 20, SD = 4; 69% female). Two samples of athletes (226 pain-free athletes and 232 athletes with current pain) completed surveys assessing BIS- and BAS-related cognitions, emotions, and behaviours. Distinct groupings of BAS-related variables were identified in both samples, evidenced by significant positive correlations within BAS-related variables (positive affect, pain openness, approach thoughts and behaviours). Most BIS-related variables (depression, anxiety, harm beliefs, pain catastrophizing and avoidance behaviours) were also correlated in the sample of athletes with pain; however, this was not observed in pain-free athletes. In athletes with pain, BIS-related variables were significantly associated with pain variables, with this association stronger than that found for BAS-related variables. Regression analyses highlighted the pivotal role of pain catastrophizing as a predictor of pain unpleasantness and intensity. Findings shed light on the factors shaping athletes’ coping, pain perception and decisions as to whether to pause or push through. Future investigations to explore these dynamics in more depth may aid in the development of targeted interventions that enhance athletes’ ability to cope and to manage pain more effectively.

Examination of associations between psychopathy and neural reinforcement sensitivity theory constructs.

We investigated psychopathy from the neurobiological perspective of reinforcement sensitivity theory (RST). In contrast to previous semantically derived self-report scales, we operationalised RST systems neurally with evoked electroencephalography (EEG). Participants were from a community sample weighted towards externalising psychopathology. We compared the Carver & White Behavioural Inhibition System (BIS)/Behavioural Approach System (BAS) scales with EEG responses associated with RST's systems of goal conflict (aka 'behavioural inhibition'), repulsion/outcome conflict (aka 'fight/flight/freeze') and attraction (aka 'approach'). Bivariate correlations and multiple regression analysis yielded results generally consistent with past literature for associations between psychopathy and the self-report BIS/BAS scales. There were some differences from self-report associations with neural measures of RST. With EEG measures, (1) no meaningful associations were observed between any psychopathy scales and the attraction system; (2) affective-interpersonal traits of psychopathy were negatively associated with goal conflict; (3) disinhibition-behavioural traits of psychopathy were negatively associated with goal conflict but, unexpectedly, positively associated with outcome conflict. These results indicate frontal-temporal-limbic circuit dysfunction in psychopathy as specific domains were linked to neural deficits in goal conflict processing, but there was no evidence for deficits in attraction-related processes.

Inhibition and Activation Systems of Behavior and Suicide Mediating Role of Cognitive Emotion Regulation.

This study aimed to predict suicide attempts based on behavioral activation and inhibition systems (BAS/BIS) with the mediating role of cognitive emotion regulation (CER) strategies among adolescents of Abyek City. The research methodology was descriptive-correlational. The cluster sampling method was used, and the resulting sample included 194 adolescents who responded to the BAS/BIS questionnaire (Carver & White, 1994), CER questionnaire, and Beck scale for suicide ideation. Path analysis was employed to evaluate the proposed model using AMOS 24.0 and SPSS 27 softwares. The findings indicate that the proposed model is fitted with the data well. The results of path analysis showed that the BAS/BIS systems explain 27% of the variance of maladaptive CER and 61% of the variance of adaptive CER. In addition, maladaptive CER, BAS, and BIS explain 65% of the variance of suicide attempts. Low levels of BAS, high levels of BIS, and the use of maladaptive CER skills can be considered risk factors for suicide attempts in adolescents.

Designing and Testing the Structural Model of Online Games Addiction Based on Brain-Behavioral Systems: The Mediating Role of Cognitive Fusion and Experiential Avoidance

Introduction: Online games addiction is a growing concern which the prevalence is estimated at 1.2 to 8.5 percent among teenagers and young adults. Aim: The present study was conducted with the aim of investigating the mediating role of cognitive fusion and experiential avoidance in the relationship between brain-behavioral systems and addiction to online games. Method: In terms of method, the research was among descriptive-correlation researches of structural equations type. The statistical population included all the students of the first year of high school in the education and training region of Hormozgan Bastak in the academic year of 2021-2022 which 350 people were selected as a sample using the multi-stage cluster random sampling method. They responded to the questionnaires of behavioral inhibition/activation systems (1994), cognitive fusion (2014), acceptance and action - second edition (2011) and online games addiction(2002). Structural modeling was used to analyze the data. Results: The results showed that the behavioral activation system and the behavioral inhibition system have a significant direct relationship with the online games addiction with coefficient values of 0.46 and 0.42, respectively (P &lt; 0.001). Also, the behavioral activation system and the behavioral inhibition system are significantly related to online game addiction indirectly with the mediation of experiential avoidance with a coefficient value of 0.17 and 0.15, respectively and the behavioral inhibition system with the mediation of cognitive fusion with a coefficient value of 0.21,. (P &lt; 0.001). Conclusion: In order to reduce online games addiction, experts should evaluate personality traits on the one hand in order to identify the sensitivity of behavioral inhibition/activator systems, and on the other hand, seek to reduce cognitive biases along with cognitive and retrospective challenges.

The role of brain activation and inhibition systems on self- Destructive behaviors with the mediating role of emotional dysregulation in teenage girls with borderline personality

Introduction: Borderline personality disorder (BPD) is a mental health condition characterized by instability in mood and interpersonal relationships. These patients are on the border between neurosis and psychosis. Aim: This study aimed to investigate the role of Behavioral Inhibition Systems/Behavioral Activation Systems in self-destructive behaviors in female vocational school students with BPD according to the mediating role of emotional dysregulation. Method: The research had a descriptive-correlational method, and its statistical population consisted of all female students with BPD at technical and vocational schools in an educational district of Tehran. 176 students were selected using the purposive sampling method. Data collection tool included Jackson and Claridge's Borderline Personality Disorder Scale (1991), Behavioral Inhibition System/Behavioral Activation System Questionnaire by Carver and White (1994), Self-Destructive Behaviors Questionnaire by Sansone et al. (1998), and Difficulties in emotion regulation scale by Gratz and Roemer (2004). Data were analyzed using the PLS-SEM method with SmartPLS software. Results: The indirect effect of BIS/BAS on self-destructive behaviors with a mediating role of emotional dysregulation was -0.553 and significant (p&lt;0.05). The direct effect of BIS/BAS on emotional dysregulation was -0.436 and significant (p&lt; 0.05). Furthermore, the direct effect of BIS/BAS on self-destructive behaviors was -0.504 and significant (p&lt;0.05), and the direct effect of emotional dysregulation on self-destructive behaviors was 0.506 and significant (p&lt;0.05). Conclusion: There was a significant relationship between behavioral activation and inhibition systems with self-destructive behaviors according to a mediating role of emotional dysregulation.
