The push of social pain: Does rejection's sting motivate subsequent social reconnection?

Psychometric properties and item response theory analysis of the Persian version of the social pain questionnaire

Introduction

Social pain is an emotional reaction which is triggered by social exclusion and has been extensively investigated in the literature. The Social Pain Questionnaire (SPQ) is a self-report instrument which is the only scale for measuring social pain as a dispositional factor. The current study aimed at examining the psychometric properties of the SPQ in an Iranian sample.

Materials and methods

A sample of participants (N = 400) was recruited in a cross-sectional validation study. Exploratory Factor Analysis (EFA) as well as Confirmatory Factor Analysis (CFA) were conducted. The Item Response Theory (IRT) model parameters were evaluated and item response category curves were presented. Convergent and divergent validities as well as the reliability (by using Cronbach's alpha coefficient) were also assessed.

Results

The SPQ's unidimensionality was affirmed (RMSEA = 0.078; CFI = 0.915; TLI = 0.99) and its internal consistency was robust (Cronbach's α = 0.94). The correlation between the SPQ and the following measures endorsed its divergent and convergent validity: Self-esteem (r = -0.424), Perceived Social Support (r = -0.161), and Interpersonal Sensitivity (r = 0.636). Finally, Item Response Theory Analysis emphasized the effectiveness of the SPQ items in discerning various levels of social pain. The theta level ranged between -1 and + 1.2 and the IRT-based marginal reliability was 0.92 for the total score.

Discussion

The Persian SPQ stands as a reliable and valid measure for evaluating social pain. This scale has the potential to stimulate further research in the field for both clinical and non-clinical settings.

Conclusion

By employing Item Response Theory (IRT) analysis, we have transcended the theoretical psychometric evaluation of the SPQ scale and demonstrated that SPQ is a unidimensional, valid and reliable measurement tool.

Social pain sharing boosts interpersonal brain synchronization in female cooperation

Social pain sharing promotes cooperation, but we still don't know its neural basis. The present study employed functional near-infrared spectroscopy (fNIRS)-based hyperscanning technology to investigate whether interpersonal brain synchronization (IBS) increased between females engaging in cooperative activities after a shared experience of social pain. We utilized the Cyberball paradigm, manipulating social pain by regulating the number of catches for the participants. Dyads in the shared social pain (SP) group received passes only at the beginning of the game, whereas dyads in the control (CT) group had the same number of catches as other players. The results indicate that participants in the SP group showed significant IBS in the right superior frontal cortex (r-SFC, p < 0.05) and left middle frontal cortex (l-MFC, p < 0.05), but no channels in the CT group showed significant IBS (p > 0.05). Further analysis revealed that IBS in r-SFC was significantly higher in the SP group compared to the CT group (p < 0.05). Additionally, IBS in r-SFC was positively correlated with the level of cooperation (r = 0.66, p < 0.001). This study elucidates the neural basis of enhanced cooperation facilitated by shared social pain at the interbrain level. However, it is crucial to acknowledge that this study exclusively enrolled female participants. The generalizability of these findings across genders is yet to be confirmed.

Sensitivity to ostracism is blunted in suicide attempters only when they report suicidal ideation

BACKGROUND

Modified pain perception is at the core of many theories on suicide; however, studies on the relationship between pain perception and suicidal behavior (attempt) have produced contradictory results. In this experimental study, we investigated whether physical pain and social pain are concomitantly influenced by suicidal ideation (SI) and past suicidal behavior.

METHODS

155 inpatients with depression (90 with and 65 without past history of suicide attempt) were included. They underwent thermal stimulation of the skin to assess physical pain tolerance and played the Cyberball game to assess their sensitivity to ostracism (social pain). Participants self-assessed current SI through the specific item in the Beck Depression Inventory.

RESULTS

Pain tolerance was not associated with history of suicide attempt, current SI, and their interaction. Social pain was associated with the interaction between history of suicide attempt and current SI. Social pain was decreased in suicide attempters, compared with non-attempters, only when they reported current SI.

LIMITATIONS

Cyberball game may not be representative of everyday stress and ecological social context.

CONCLUSIONS

Unlike what suggested by many theories, pain tolerance does not seem to be necessary to attempt suicide. Suicide attempters with current SI displayed blunted sensitivity to ostracism and could be less willing to restore social affiliation compared with non-attempters.

Social anxiety inhibits needs repair following exclusion in both relational and non-relational reward contexts: The mediating role of positive affect

The pain of social exclusion can motivate people to capitalize on opportunities to reconnect with others and repair their self-esteem and feelings of belongingness. This effect is often diminished for those with high social anxiety (HSA). Prior research suggests this may be due to their diminished capacity for recognizing and emotionally responding to relational reward cues. We investigated whether non-relational success experiences in the aftermath of exclusion may be an alternative means of repairing threatened self-esteem and belongingness in HSA individuals. In a preregistered, online study, we threatened belongingness and self-esteem in 422 participants by excluding them in a Cyberball game and then assigned them to one of three conditions: Relational Repair, Non-Relational Repair, or a No-Repair control condition. Results showed that both repair contexts facilitated needs repair relative to the no-repair control condition, and mediation analyses suggested this effect was driven by increased positive affect (PA). HSA individuals were less likely to restore needs regardless of condition and this effect appeared to be driven by low PA. Findings emphasize the critical role of PA for restoring threatened needs in the aftermath of exclusion and suggest that HSA inhibits needs repair processes across both relational and non-relational reward contexts.

Brain Systems Underlying Fundamental Motivations of Human Social Conformity

From birth to adulthood, we often align our behaviors, attitudes, and opinions with a majority, a phenomenon known as social conformity. A seminal framework has proposed that conformity behaviors are mainly driven by three fundamental motives: a desire to gain more information to be accurate, to obtain social approval from others, and to maintain a favorable self-concept. Despite extensive interest in neuroimaging investigation of social conformity, the relationship between brain systems and these fundamental motivations has yet to be established. Here, we reviewed brain imaging findings of social conformity with a componential framework, aiming to reveal the neuropsychological substrates underlying different conformity motivations. First, information-seeking engages the evaluation of social information, information integration, and modification of task-related activity, corresponding to brain networks implicated in reward, cognitive control, and tasks at hand. Second, social acceptance involves the anticipation of social acceptance or rejection and mental state attribution, mediated by networks of reward, punishment, and mentalizing. Third, self-enhancement entails the excessive representation of positive self-related information and suppression of negative self-related information, ingroup favoritism and/or outgroup derogation, and elaborated mentalizing processes to the ingroup, supported by brain systems of reward, punishment, and mentalizing. Therefore, recent brain imaging studies have provided important insights into the fundamental motivations of social conformity in terms of component processes and brain mechanisms.

How and When Perpetrators Reflect on and Respond to Their Workplace Ostracism Behavior: A Moral Cleansing Lens

Purpose

This study investigates the association between the previous workplace ostracism of employees and their subsequent helping behavior by drawing on moral cleansing theory in the Chinese context, exploring the mediating roles of employees' guilt and perceived loss of moral credit and the moderating role of their moral identity symbolization.

Sample and Method

The data were collected from a two-stage time-lagged survey of 284 Chinese employees. Regression analysis and the bootstrapping method are used in this article to examine the theoretical hypotheses.

Results

The results indicate that employees' previous ostracism behaviors positively affected their guilt experience and perceived loss of moral credit. Subsequently, the relationship between employees' workplace ostracism and their helping behavior is mediated by guilt experience and perceived loss of moral credit. Furthermore, moral identity symbolization positively moderated the indirect "workplace ostracism-helping behavior" linkage via guilt and perceived loss of moral credits; in other words, for employees who have a higher degree of moral identity symbolization, the mediating effect is more significant, and vice versa.

Conclusion

This study does not merely clarify the theoretical relationship between perpetrators' workplace ostracism and their helping behavior, which enriches the explanatory logic of related research on workplace ostracism and the cause of helping behavior, but also expand the application scope of moral cleansing theory. Further, we aim practically to bring enlightenment to human resource management reform, corporate culture construction, and positive behavior management.

How Are Bystanders Involved in Cyberbullying? A Latent Class Analysis of the Cyberbystander and Their Characteristics in Different Intervention Stages

BACKGROUND

Cyberbullying is a phenomenon that occurs by means of digital devices in virtual environments. Although research reveals the relevant role played by bystanders in stopping cyberbullying, the patterns of cyberbullying bystanders among Chinese college students is not clear.

DATA

Participants were 1025 Chinese college students (62.0% girls, 38.0% boys). The present analyses empirically explored the roles of cyberbystanders (passive outsider online, defender of the cybervictim online, reinforcer of the cyberbully online, passive face-to-face outsider, face-to-face defender of the cybervictim, and face-to-face reinforcer of the cyberbully) using latent class analysis.

RESULTS

(1) Five latent classes were identified: defensive bystander (17.9%), indifferent bystander (10.1%), low-involved bystander (10.2%), medium-involved bystander (45.7%), and high-involved bystander (16.0%). (2) The cyberbystander patterns varied significantly for all stages of bullying intervention, among which the defensive bystander had the lowest score in the notice stage but the highest scores in the other stages. (3) There was a graded relationship between the five latent classes and the level of social network site use and cyber-victimization experience. College students with high usage of social network sites and high cyber-victimization experience were more likely to engage in diverse bystander behaviors.

Neural Mechanisms of Intergroup Exclusion and Retaliatory Aggression

Aggression occurs frequently and severely between rival groups. Although there has been much study into the psychological and socio-ecological determinants of intergroup aggression, the neuroscience of this phenomenon remains incomplete. To examine the neural correlates of aggression directed at outgroup (versus ingroup) targets, we recruited 35 healthy young male participants who were current or former students of the same university. While undergoing functional MRI, participants completed an aggression task against both an ingroup and an outgroup opponent in which their opponents repeatedly provoked them at varying levels and then participants could retaliate. Participants were then socially included and then excluded by two outgroup members and then completed the same aggression task against the same two opponents. Both before and after outgroup exclusion, aggression towards outgroup members was positively associated with activity in the ventral striatum during decisions about how aggressive to be towards their outgroup opponent. Aggression towards outgroup members was also linked to greater post-exclusion activity in the rostral and dorsal medial prefrontal cortex during provocation from their outgroup opponent. These altered patterns of brain activity suggest that frontostriatal mechanisms may play a significant role in motivating aggression towards outgroup members.

Integrative Brain Dynamics in Childhood Bullying Victimization: Cognitive and Emotional Convergence Associated With Stress Psychopathology

Bullying victimization is a form of psychological stress that is associated with poor outcomes in the areas of mental health and learning. Although the emotional maladjustment and memory impairment following interpersonal stress are well documented, the mechanisms of complex cerebral dysfunctions have neither been outlined nor studied in depth in the context of childhood bullying victimization. As a contribution to the cross-disciplinary field of developmental psychology and neuroscience, we review the neuropathophysiology of early life stress, as well as general psychological stress to synthesize the data and clarify the versatile dynamics within neuronal networks linked to bullying victimization. The stress-induced neuropsychological cascade and associated cerebral networks with a focus on cognitive and emotional convergence are described. The main findings are that stress-evoked neuroendocrine reactivity relates to neuromodulation and limbic dysregulation that hinder emotion processing and executive functioning such as semantic cognition, cognitive flexibility, and learning. Developmental aspects and interacting neural mechanisms linked to distressed cognitive and emotional processing are pinpointed and potential theory-of-mind nuances in targets of bullying are presented. The results show that childhood stress psychopathology is associated with a complex interplay where the major role belongs to, but is not limited to, the amygdala, fusiform gyrus, insula, striatum, and prefrontal cortex. This interplay contributes to the sensitivity toward facial expressions, poor cognitive reasoning, and distress that affect behavioral modulation and emotion regulation. We integrate the data on major brain dynamics in stress neuroactivity that can be associated with childhood psychopathology to help inform future studies that are focused on the treatment and prevention of psychiatric disorders and learning problems in bullied children and adolescents.

The Cognitive, Affective and Somatic Empathy Scales for Adults

The Cognitive, Affective and Somatic Empathy Scales (CASES) assess three forms of empathy, each with subscales for positive and negative empathy. The present study extends this child instrument to adults and examines its factor structure and construct validity. A secondary aim is to investigate the under-researched area of positive empathy. Community samples totaling 2,604 adults completed the CASES for adults, together with scales assessing construct validity. Confirmatory factor analysis supported the three-factor cognitive-affective-somatic model and a two-factor positive-negative empathy model. Findings were replicated in a second independent sample. Internal reliabilities ranged from .80 to .92. Individuals with higher psychopathy and stimulation-seeking scores were less impaired in their empathic reactions to positive relative to negative valence events, suggesting that they are relatively capable of responding emotionally to rewarding events. Somatic empathy was most strongly associated with pleasure in affective touch and with female > male gender differences. While proactive aggression was associated with reduced cognitive and affective empathy, reactive aggression was associated with increased empathy. Findings provide initial support for the utility of CASES for assessing different forms of empathy and suggest that the balance between positive and negative empathy could provide new insights into psychological traits.

Social touch deprivation during COVID-19: effects on psychological wellbeing and craving interpersonal touch

Social touch has positive effects on social affiliation and stress alleviation. However, its ubiquitous presence in human life does not allow the study of social touch deprivation 'in the wild'. Nevertheless, COVID-19-related restrictions such as social distancing allowed the systematic study of the degree to which social distancing affects tactile experiences and mental health. In this study, 1746 participants completed an online survey to examine intimate, friendly and professional touch experiences during COVID-19-related restrictions, their impact on mental health and the extent to which touch deprivation results in craving touch. We found that intimate touch deprivation during COVID-19-related restrictions is associated with higher anxiety and greater loneliness even though this type of touch is still the most experienced during the pandemic. Moreover, intimate touch is reported as the type of touch most craved during this period, thus being more prominent as the days practising social distancing increase. However, our results also show that the degree to which individuals crave touch during this period depends on individual differences in attachment style: the more anxiously attached, the more touch is craved; with the reverse pattern for avoidantly attached. These findings point to the important role of interpersonal and particularly intimate touch in times of distress and uncertainty.

Reconnecting in the Face of Exclusion: Individuals with High Social Anxiety May Feel the Push of Social Pain, but not the Pull of Social Rewards

Background

Previous research has shown that high levels of trait social anxiety (SA) disrupt the social repair processes following a painful social exclusion, but the cognitive mechanisms involved in these processes and how trait SA may disrupt them remain unknown.

Methods

We conducted a preregistered study on Prolific participants (N = 452) who were assigned to experience either social exclusion or inclusion and were then exposed to follow-up opportunities for social reconnection.

Results

Moderated mediation analyses revealed that irrespective of levels of SA, participants responded to social pain with heightened approach motivation and greater downstream positive affect. Exploratory analyses revealed that heightened desire to affiliate was driven by increased curiosity and attention to social rewards. Moreover, higher SA was associated with lower overall desire to affiliate and this relationship between SA and affiliation was mediated by diminished reward responsiveness.

Conclusions

Findings highlight the roles of goal pursuit and social reward responsiveness in social repair and how high levels of trait SA may disrupt these processes.

Exclusion Expected? Cardiac Slowing Upon Peer Exclusion Links Preschool Parent Representations to School-Age Peer Relationships

Attachment theory proposes that children's representations of interactions with caregivers guide information-processing about others, bridging interpersonal domains. In a longitudinal study (N = 165), preschoolers (M_age  = 5.19 years) completed the MacArthur Story Stem Battery to assess parent representations. At school-age (M_age  = 8.42 years), children played a virtual ballgame with peers who eventually excluded them to track event-related cardiac slowing, a physiological correlate of rejection, especially when unexpected. At both ages, parents and teachers reported on peer and emotional problems. During exclusion versus inclusion-related events, cardiac slowing was associated with greater positive parent representations and fewer emerging peer problems. Cardiac slowing served as a mediator between positive parent representations and peer problems, supporting a potential psychophysiological mechanism underlying the generalization of attachment-related representations to peer relationships.

Construct Validation of Experimental Manipulations in Social Psychology: Current Practices and Recommendations for the Future

Experimental manipulations in social psychology must exhibit construct validity by influencing their intended psychological constructs. Yet how do experimenters in social psychology attempt to establish the construct validity of their manipulations? Following a preregistered plan, we coded 348 experimental manipulations from the 2017 issues of the Journal of Personality and Social Psychology. Representing a reliance on "on-the-fly" experimentation, the vast majority of these manipulations were created ad hoc for a given study and were not previously validated before implementation. A minority of manipulations had their construct validity evaluated by pilot testing before implementation or via a manipulation check. Of the manipulation checks administered, most were face valid, single-item self-reports, and only a few met criteria for "true" validation. In aggregate, roughly two fifths of manipulations relied solely on face validity. To the extent that they are representative of the field, these results suggest that best practices for validating manipulations are not commonplace-a potential contributor to replicability issues. These issues can be remedied by validating manipulations before implementation using validated manipulation checks, standardizing manipulation protocols, estimating the size and duration of manipulations' effects, and estimating each manipulation's effects on multiple constructs within the target nomological network.

Coping with social wounds: How social pain and social anxiety influence access to social rewards

BACKGROUND AND OBJECTIVES

Prior studies have shown that people display signs of increased social approach motivation and affiliative behaviour in response to social exclusion. This response is considered an adaptive strategy that serves to repair damage to social networks and increase access to mood-enhancing social rewards. However, heightened trait social anxiety (SA) has been linked to decreased approach motivation and responsiveness to social rewards. In the current preliminary experimental study, we tested whether trait SA inhibits the expected increase in social approach following the pain of exclusion. We then tested whether diminished social approach is associated with reduced positive affect.

METHODS

Participants played a game of Cyberball and were randomly assigned to receive significantly fewer passes (exclusion condition) or an equal number of passes (control condition) as other players. Subsequently, participants were given the opportunity to engage in an online social interaction activity with avatars they believed were other participants.

RESULTS

Analyses revealed that the exclusion condition led to greater social pain than the control condition. Across conditions, greater social pain was associated with higher levels of approach motivation in anticipation of the social interaction activity, but only for individuals with lower levels of trait SA. Finally, when controlling for levels of trait SA, social pain was associated with positive affect following the social interaction activity, but only for individuals with higher levels of approach motivation.

LIMITATIONS

Participants consisted predominantly of female undergraduates, limiting generalizability of these data. As well, hypotheses were supported for the measure of approach motivation but not the measure of approach behaviour. Finally, this study was not powered to enable moderated mediation analyses, which would have provided the most direct test of the hypothesized model.

CONCLUSIONS

Heightened approach motivation in the face of social pain may facilitate increased positive affect. However, higher levels of trait SA dampen approach motivation. Future well-powered studies should use moderated mediation analyses to test the hypothesized model more parsimoniously.

Social exclusion modulates dual mechanisms of cognitive control: Evidence from ERPs

Many studies have investigated how social exclusion influences cognitive control but reported inconsistent findings. Based on the dual mechanisms of control framework, this study investigated how social exclusion influences proactive and reactive modes of control (Experiment 1) and the underlying mechanisms (Experiment 2). The Cyberball game was used to manipulate social exclusion. Eighty-six female participants (about 40 for each experiment) performed cognitive control tasks while event-related potentials were recorded. In Experiment 1, an AX Continuous Performance Task (AX-CPT) was adopted to differentiate between proactive and reactive control. Results showed that social exclusion weakened proactive control but enhanced reactive control, as reflected by the weaker proactive control indicators (i.e., P3b and CNV), but strengthened reactive control indicators (accuracy and N2) in excluded individuals. More importantly, in Experiment 2, through varying in whether task cues were available before or after target onset in a cued-flanker task, we further manipulated the possibility of engaging proactive control, and found the weakened proactive control could be attributed to both impaired cognitive ability and lowered motivation to engage proactive control in excluded individuals. Together, these results provide insight on how social exclusion influences cognitive control and suggest promising implications for designing effective interventions to relieve the negative impact of social exclusion.

Interaction between social pain and physical pain

People often experience two types of pain: social pain and physical pain. The former is related to psychological distance from other people or social groups, whereas the latter is associated with actual or potential tissue damage. Social pain caused by interpersonal interactions causes negative feelings in individuals and has negative consequences to the same degree as physical pain. Various studies have shown an interaction between social pain and physical pain, not only in behavioral performance but also in activities within shared neural regions. Accordingly, the present paper reviews: (1) the interaction between social pain and physical pain in individuals’ behavioral performances; and (2) the overlap in neural circuitry as regards the processing of social pain and physical pain. Understanding the relationship between social pain and physical pain might provide new insights into the nature of these two types of pain, and thus may further contribute to the treatment of illnesses associated with both types of painful experience.

Modulation of Mu suppression during visual perspective taking by social rejection

Perspective taking is crucial for maintaining positive relationship with others in social interaction. Previous studies have shown that perspective-taking ability can be modulated by the experience of social rejection. The present study examined event-related dynamics of Mu power (8-13 Hz) in the EEG at sensorimotor area while rejected individuals performing visual perspective taking task. The reaction time and accuracy results showed that social rejection impaired self-regulation and impulsive control. The sensorimotor Mu suppression was enhanced during late processing (400-800 ms) of visual perspective taking in rejection individuals. Specifically, social rejection motivated sensitivity to other's perspective compared to one's own perspective. These findings verify the model of social monitoring system and the cognitive deconstruction theory partially by experiment, and even extend previous studies with that Mu suppression for visual perspective taking can be modulated by social rejection.

Feeling Hurt: Revisiting the Relationship Between Social and Physical Pain

Pain overlap theory has generated decades of controversy and still receives considerable research attention. A major advance has been the revelation that social and physical pain activate similar neural regions, providing suggestive evidence of a “piggybacked” alarm system that coevolved to detect social exclusion. Recent developments, however, have brought neural evidence for pain overlap into question. We analyze these developments from a social psychological perspective and identify the need for a reformulated approach. To meet this need, we provide a framework that a priori predicts generalized overlap and specific divergence across a range of biopsychosocial domains. The framework points to a functional pattern for similarities and differences, which can be utilized to generate testable hypotheses so that the field can move forward. To demonstrate the utility and promise of the framework, we identify key hypotheses relating to attention, motivation, and responses to pain, and review research relevant to these hypotheses.

When less is more: mindfulness predicts adaptive affective responding to rejection via reduced prefrontal recruitment

Social rejection is a distressing and painful event that many people must cope with on a frequent basis. Mindfulness—defined here as a mental state of receptive attentiveness to internal and external stimuli as they arise, moment-to-moment—may buffer such social distress. However, little research indicates whether mindful individuals adaptively regulate the distress of rejection—or the neural mechanisms underlying this potential capacity. To fill these gaps in the literature, participants reported their trait mindfulness and then completed a social rejection paradigm (Cyberball) while undergoing functional magnetic resonance imaging. Approximately 1 hour after the rejection incident, participants reported their level of distress during rejection (i.e. social distress). Mindfulness was associated with less distress during rejection. This relation was mediated by lower activation in the left ventrolateral prefrontal cortex during the rejection incident, a brain region reliably associated with the inhibition of negative affect. Mindfulness was also correlated with less functional connectivity between the left ventrolateral prefrontal cortex and the bilateral amygdala and the dorsal anterior cingulate cortex, which play a critical role in the generation of social distress. Mindfulness may relate to effective coping with rejection by not over-activating top-down regulatory mechanisms, potentially resulting in more effective long-term emotion-regulation.

The soothing function of touch: affective touch reduces feelings of social exclusion

The mammalian need for social proximity, attachment and belonging may have an adaptive and evolutionary value in terms of survival and reproductive success. Consequently, ostracism may induce strong negative feelings of social exclusion. Recent studies suggest that slow, affective touch, which is mediated by a separate, specific C tactile neurophysiological system than faster, neutral touch, modulates the perception of physical pain. However, it remains unknown whether slow, affective touch, can also reduce feelings of social exclusion, a form of social pain. Here, we employed a social exclusion paradigm, namely the Cyberball task (N = 84), to examine whether the administration of slow, affective touch may reduce the negative feelings of ostracism induced by the social exclusion manipulations of the Cyberball task. As predicted, the provision of slow-affective, as compared to fast-neutral, touch led to a specific decrease in feelings of social exclusion, beyond general mood effects. These findings point to the soothing function of slow, affective touch, particularly in the context of social separation or rejection, and suggest a specific relation between affective touch and social bonding.

Neural responses to social exclusion in adolescents: Effects of peer status

We examined whether adolescents' neural responses to social exclusion and inclusion are influenced by their own popularity and acceptance and by the popularity of their excluders and includers. Accepted adolescents are highly prosocial. In contrast, popular adolescents, who are central and influential, show prosocial as well as antisocial behaviors, such as peer exclusion. Fifty-two 12-16 year-old adolescents underwent an functional magnetic resonance imaging (fMRI) scan while playing the ball-tossing game Cyberball in which they received or did not receive the ball from other virtual players. The other virtual players were described as either highly popular or average in popularity. Participants' own popularity and acceptance were assessed with peer nominations at school (n = 31). Participants' acceptance was positively correlated with activity of the dorsal anterior cingulate cortex (ACC) during exclusion. Participants' popularity was positively associated with ventral striatum and medial prefrontal cortex activity during exclusion, but only when the excluders were popular virtual players. Participants showed increased rostral ACC activation to inclusion by players who were average in popularity. These findings indicate that peer status plays an important role in adolescents' neural processing of social exclusion and inclusion. Moreover, these findings underscore that popularity and acceptance are distinct types of high peer status in adolescence, with not only distinct behavioral correlates, but also distinct neural correlates.

Deficits in Response Inhibition in Patients with Attention-Deficit/Hyperactivity Disorder: The Impaired Self-Protection System Hypothesis

Problems in inhibitory control are regarded in Psychology as a key problem associated with attention-deficit/hyperactivity disorder (ADHD). They, however, might not be primary deficits, but instead a consequence of inattention. At least two components have been identified and dissociated in studies in regards to inhibitory control: interference suppression, responsible for controlling interference by resisting irrelevant or misleading information, and response inhibition, referring to withholding a response or overriding an ongoing behavior. Poor error awareness and self-monitoring undermine an individual's ability to inhibit inadequate responses and change course of action. In non-social contexts, an individual depends on his own cognition to regulate his mistakes. In social contexts, however, there are many social cues that should help that individual to perceive his mistakes and inhibit inadequate responses. The processes involved in perceiving and interpreting those social cues are arguably part of a self-protection system (SPS). Individuals with ADHD not only present impulsive behaviors in social contexts, but also have difficulty perceiving their inadequate responses and overriding ongoing actions toward more appropriate ones. In this paper, we discuss that those difficulties are arguably a consequence of an impaired SPS, due to visual attention deficits and subsequent failure in perceiving and recognizing accurately negative emotions in facial expressions, especially anger. We discuss evidence that children with ADHD exhibit problems in a series of components involved in the activation of that system and advocate that the inability to identify the anger expressed by others, and thus, not experiencing the fear response that should follow, is, ultimately, what prevents them from inhibiting the ongoing inappropriate behavior, since a potential threat is not registered. Getting involved in high-risk situations, such as reckless driving, could also be a consequence of not registering a threat and thus, not experiencing fear.

Cognitive, Emotional, Temperament, and Personality Trait Correlates of Suicidal Behavior

Suicide is one of the leading causes of violent death in many countries and its prevention is included in worldwide health objectives. Currently, the DSM-5 considers suicidal behavior as an entity that requires further study. Among the three validators required for considering a psychiatric disorder, there is one based on psychological correlates, biological markers, and patterns of comorbidity. This review includes the most important and recent studies on psychological factors: cognitive, emotional, temperament, and personality correlates (unrelated to diagnostic criteria). We included classic factors related to suicidal behavior such as cognitive, inflexibility, problem-solving, coping, rumination, thought suppression, decision-making, autobiographical memory, working memory, language fluency, burdensomeness, belongingness, fearless, pain insensitivity, impulsiveness, aggressiveness, and hopelessness. The personality correlates reported are mainly based on the personality theories of Cloninger, Costa and McCrae, and Eysenck. Moreover, it explores conceptual links to other new pathways in psychological factors, emptiness, and psychological pain as a possible origin and common end path for a portion of suicidal behaviors.
