RESUMO

Previous experimental work showed that young adults reporting loneliness performed less well on emotion recognition tasks (Diagnostic Analysis of Nonverbal Accuracy [DANVA-2]) if they were framed as indicators of social aptitude, but not when the same tasks were framed as indexing academic aptitude. Such findings suggested that undergraduates reporting loneliness possessed the social monitoring skills necessary to read the emotions underlying others' facial expressions, but that they choked under social pressure. It has also been found that undergraduates reporting loneliness have better recall for both positive and negative social information than their non-lonely counterparts. Whether those effects are evident across different age groups has not been examined. Using data from the British Broadcasting Corporation (BBC) Loneliness Experiment that included participants aged 16-99 years (N = 54,060), we (i) test for replication in a larger worldwide sample and (ii) extend those linear model analyses to other age groups. We found only effects for participants aged 25-34 years: In this age group, loneliness was associated with increased recall of negative individual information, and with choking under social pressure during the emotion recognition task; those effects were small. We did not find any such effects among participants in other age groups. Our findings suggest that different cognitive processes may be associated with loneliness in different age groups, highlighting the importance of life-course approaches in this area.

RESUMO

Global cerebral ischemia in rodents, which mimics cardiac arrest in humans, is associated with a surge in endocannabinoids and increased transmission of dopamine and glutamate leading to excitotoxic cell death. The current study assessed the role of CB1 receptor activation at the moment of an ischemic insult on ensuing regulation of stress and reward signaling molecules, neuronal injury and anxiety-like behavior. Male Wistar rats were separated into 4 groups (n=10/group); sham and ischemic rats administered the CB1 endocannabinoid receptor antagonist AM251 (2mg/kg, i.p.) 30min prior to global cerebral ischemia, and vehicle-treated counterparts. The effects of CB1 receptor blockade on corticotropin-releasing hormone (CRH), vesicular glutamate transporter 2 (vGluT2), tyrosine hydroxylase (TH) and dopamine receptor 1 (DRD1) signaling expression, together with CA1 neuronal damage and anxiety-like behaviors were assessed. Our findings show attenuated CA1 injury and behavioral deficits in AM251-treated ischemic rats. AM251-pretreatment also partially or completely reversed ischemia-induced alterations in TH-ir expression at the hippocampus, ventral tegmental area (VTA), nucleus accumbens (NAc) and basolateral amygdala (BLA), normalized DRD1-ir at the medial forebrain bundle, and diminished BLA and PVN-CRH expression. All groups showed comparable vGluT2 expression at the BLA and PVN-parvocellular subdivision. These findings support a determinant role of CB1 receptor activation at time of ischemia on functional recovery. They also support "state-dependent" effects of endocannabinoids, raising considerations in the development of effective molecules to regulate HPA axis function and mood disorders following cardiac arrest and stroke.

RESUMO

Lonely individuals may decode social cues well but have difficulty putting such skills to use precisely when they need them--in social situations. In four studies, we examined whether lonely people choke under social pressure by asking participants to complete social sensitivity tasks framed as diagnostic of social skills or nonsocial skills. Across studies, lonely participants performed worse than nonlonely participants on social sensitivity tasks framed as tests of social aptitude, but they performed just as well or better than the nonlonely when the same tasks were framed as tests of academic aptitude. Mediational analyses in Study 3 and misattribution effects in Study 4 indicate that anxiety plays an important role in this choking effect. This research suggests that lonely individuals may not need to acquire social skills to escape loneliness; instead, they must learn to cope with performance anxiety in interpersonal interactions.

RESUMO

Purpose. To describe the self-reported risky behaviors associated with adolescent social media use. Methods. Adolescents ages 13 to 21 years were recruited from a large, urban academic center to complete a written survey regarding social media use. Results are presented as frequencies and percentage; nominal variables were compared using χ(2) analysis. Results. Almost all participants (93%) reported belonging to a social media site. The majority of adolescents (72%) access the Internet with a phone. Nearly half (49%) of participants accept friend requests from strangers, 42% send friend requests to strangers, and 55% of participants report meeting people from social media sites in person. Conclusion. Adolescents self-report engaging in a number of risky behaviors when they use social media. Teenagers' use of social media is an additional behavior that requires attention and monitoring.

RESUMO

In the current paper, the authors posit that trait self-esteem moderates the relationship between social rejection and decrements in self-control, propose an information-processing account of trait self-esteem's moderating influence and discuss three tests of this theory. The authors measured trait self-esteem, experimentally manipulated social rejection and assessed subsequent self-control in Studies 1 and 2. Additionally, Study 3 framed a self-control task as diagnostic of social skills to examine motivational influences. Together, the results reveal that rejection impairs self-control, but only among low self-esteem individuals. Moreover, this decrement in self-control only emerged when the task had no social implications-suggesting that low self-esteem individuals exert effort on tasks of social value and are otherwise preoccupied with belonging needs when completing nonsocial tasks.

RESUMO

Lonely individuals typically fear negative evaluation and engage in overly cautious social behaviors that perpetuate their social isolation. Recent research has found analogous security-oriented (i.e., prevention-focused) responses following experiences highlighting concerns with social loss but differing growth-oriented (i.e., promotion-focused ) responses, such as attempts at social engagement, following experiences highlighting concerns with social gain. The present studies thus investigated whether fostering a promotion focus among lonely individuals through subtle primes of acceptance could reduce their self-protective social avoidance. This hypothesis was supported across four studies in which the links between primed acceptance and promotion-focused motivations were first established, and the impact of such primes on lonely individuals' social thoughts, intentions, and behaviors were then tested. Implications of observed differences between effects of acceptance primes on lonely versus nonlonely individuals are discussed in terms of deficits versus satiation with feelings of belonging.

RESUMO

Feelings of belonging are closely linked to feelings of self-esteem. This article examines whether these feelings are regulated in a similar manner. Research on self-esteem maintenance shows that self-enhancement strategies are interchangeable; self-esteem threats in one domain instigate indirect self-affirmations in unrelated domains that effectively replace needs to directly address the original threats. From this perspective, when self-esteem threats arise from a lack of belonging, indirect self-affirmations should again be both preferred and effective. However, belonging regulation may be distinct from self-esteem regulation. From this belonging maintenance perspective, indirect affirmations that enhance esteem, but do not directly repair belonging, may be relatively less preferred and effective following belonging threats. Supporting the belonging maintenance perspective, four studies demonstrated that whereas intelligence threats tended to elicit indirect self-affirmations, belonging threats elicited relatively more direct self-affirmations. Furthermore, whereas indirect affirmation strategies effectively repaired intelligence threats they did not effectively repair belonging threats.

RESUMO

Competing predictions about the effect of social exclusion were tested by meta-analyzing findings from studies of interpersonal rejection, ostracism, and similar procedures. Rejection appears to cause a significant shift toward a more negative emotional state. Typically, however, the result was an emotionally neutral state marked by low levels of both positive and negative affect. Acceptance caused a slight increase in positive mood and a moderate increase in self-esteem. Self-esteem among rejected persons was no different from neutral controls. These findings are discussed in terms of belongingness motivation, sociometer theory, affective numbing, and self-esteem defenses.

RESUMO

Social exclusion evokes powerful motivations and emotions. The present studies examined how these motivations and emotions might differ following exclusion that is explicit, active, and direct (i.e., when one is rejected) versus implicit, passive, and indirect (i.e., when one is ignored). It was hypothesized that being rejected should produce a sense of social loss and lead to more prevention-focused responses, including withdrawal from social contact, thoughts about actions one should not have taken, and increased feelings of agitation. In contrast, being ignored should produce a sense of failure to achieve social gain and lead to more promotion-focused responses, including reengagement in social contact, thoughts about actions one should have taken, and increased feelings of dejection. These hypotheses were supported across 4 studies in which people recalled or underwent experiences of being rejected or ignored. Past research on active versus passive exclusion is reexamined and found to be consistent with these hypotheses as well.

RESUMO

Groups vary in the range of benefits they provide to members, but one potential benefit of membership is a confirmation of individuals' sense of belonging to a larger social whole. The current studies present an exploration of this potential benefit by examining the activation and amplification of group identities and memberships following rejection. Results demonstrate that rejected participants exhibited heightened activation of group constructs, social identities, and idiosyncratic group memberships (Studies 1 and 2) and judged their own groups to be more entitative (meaningful and cohesive) than other groups (Study 3) as compared to controls. Moreover, heightened activation of group constructs and entitative group memberships after rejection was associated with higher self-esteem (Studies 1 and 2) and more positive mood (Study 4). The potential use of group identity activation and amplification as an indirect belonging regulation strategy is discussed within the context of a broader belonging regulation model.

RESUMO

The skill-deficit view of loneliness posits that unskilled social interactions block lonely individuals from social inclusion. The current studies examine loneliness in relation to social attention and perception processes thought to be important for socially skilled behavior. Two studies investigate the association between social monitoring (attention to social information and cues) and self-reported loneliness and number of close social ties. In Study 1, higher levels of loneliness are related to increased rather than decreased incidental social memory. In Study 2, individuals with fewer reported friends show heightened decoding of social cues in faces and voices. Results of these studies suggest that the attentional and perceptual building blocks of socially skilled behavior remain intact, and perhaps enhanced, in lonely individuals. Implications for recent models of belonging regulation and theories of loneliness are discussed.

RESUMO

To successfully establish and maintain social relationships, individuals need to be sensitive to the thoughts and feelings of others. In the current studies, the authors predicted that individuals who are especially concerned with social connectedness--individuals high in the need to belong--would be particularly attentive to and accurate in decoding social cues. In Study 1, individual differences in the need to belong were found to be positively related to accuracy in identifying vocal tone and facial emotion. Study 2 examined attention to vocal tone and accuracy in a more complex social sensitivity task (an empathic accuracy task). Replicating the results of Study 1, need to belong scores predicted both attention to vocal tone and empathic accuracy. Study 3 provided evidence that the enhanced performance shown by those high in the need to belong is specific to social perception skills rather than to cognitive problem solving more generally.
