Estimating the Causal Effects of Social Interaction with Endogenous Networks
Jon Rogowski & Betsy Sinclair
Political Analysis, forthcoming
Abstract:
Identifying causal effects attributable to network membership is a key challenge in empirical studies of social networks. In this article, we examine the consequences of endogeneity for inferences about the effects of networks on network members' behavior. Using the House office lottery (in which newly elected members select their office spaces in a randomly chosen order) as an instrumental variable to estimate the causal impact of legislative networks on roll call behavior and cosponsorship decisions in the 105th-112th Houses, we find no evidence that office proximity affects patterns of legislative behavior. These results contrast with decades of congressional scholarship and recent empirical studies. Our analysis demonstrates the importance of accounting for selection processes and omitted variables in estimating the causal impact of networks.

Oxytocin increases willingness to socially share one's emotions
Anthony Lane et al.
International Journal of Psychology, forthcoming
Abstract:
Oxytocin (OT) is a neuropeptide that is attracting growing attention from researchers interested in human emotional and social behavior. There is indeed increasing evidence that OT has a calming effect and that it facilitates pair-bonding and social interactions. Some of OT's effects are thought to be direct, but it has been suggested that OT also may have indirect effects, mediated by changes in behavior. One potentially relevant behavioral change is an increased propensity for "emotional sharing" as this behavior, like OT, is known to have both calming and bonding effects. In this study, 60 healthy young adult men were randomly assigned to receive either intranasal placebo (PL; n = 30) or oxytocin (OT; n = 30). Participants were then instructed to retrieve a painful memory. Subsequently, OT and placebo participants' willingness to disclose to another person event-related facts (factual sharing) vs. event-related emotions (emotional sharing) was evaluated. Whereas the two groups were equally willing to disclose event-related facts, oxytocin was found to specifically increase the willingness to share event-related emotions. This study provides the first evidence that OT increases people's willingness to share their emotions. Importantly, OT did not make people more talkative (word counts were comparable across the two groups) but instead increased the willingness to share the specific component that is responsible for the calming and bonding effects of social sharing: emotions. Findings suggest that OT may shape the form of social sharing so as to maximize its benefits. This might help explain the calming and bonding effects of OT.

Oxytocin enhances pupil dilation and sensitivity to "hidden" emotional expressions
Siri Leknes et al.
Social Cognitive and Affective Neuroscience, forthcoming
Abstract:
Sensing others' emotions through subtle facial expressions is a highly important social skill. We investigated the effects of intranasal oxytocin treatment on the evaluation of explicit and "hidden" emotional expressions, and related the results to individual differences in sensitivity to others' subtle expressions of anger and happiness. Forty healthy volunteers participated in this double-blind, placebo-controlled crossover study, which shows that a single dose of intranasal oxytocin (40IU) enhanced or "sharpened" evaluative processing of others' positive and negative facial expression for both explicit and hidden emotional information. Our results point to mechanisms which could underpin oxytocin's prosocial effects in humans. Importantly, individual differences in baseline emotional sensitivity predicted oxytocin's effects on the ability to sense differences between faces with hidden emotional information. Participants with low emotional sensitivity showed greater oxytocin-induced improvement. These participants also showed larger task-related pupil dilation, suggesting that they also allocated the most attentional resources to the task. Overall, oxytocin treatment enhanced stimulus-induced pupil dilation, consistent with oxytocin enhancement of attention towards socially relevant stimuli. Since pupil dilation can be associated with increased attractiveness and approach behaviour, this effect could also represent a mechanism by which oxytocin increases human affiliation.

Disclosing information about the self is intrinsically rewarding
Diana Tamir & Jason Mitchell
Proceedings of the National Academy of Sciences, 22 May 2012, Pages 8038-8043
Abstract:
Humans devote 30-40% of speech output solely to informing others of their own subjective experiences. What drives this propensity for disclosure? Here, we test recent theories that individuals place high subjective value on opportunities to communicate their thoughts and feelings to others and that doing so engages neural and cognitive mechanisms associated with reward. Five studies provided support for this hypothesis. Self-disclosure was strongly associated with increased activation in brain regions that form the mesolimbic dopamine system, including the nucleus accumbens and ventral tegmental area. Moreover, individuals were willing to forgo money to disclose about the self. Two additional studies demonstrated that these effects stemmed from the independent value that individuals placed on self-referential thought and on simply sharing information with others. Together, these findings suggest that the human tendency to convey information about personal experience may arise from the intrinsic value associated with self-disclosure.

Effects of Financial Insecurity on Social Interactions
Hope Corman et al.
Journal of Socio-Economics, forthcoming
Abstract:
Little is known about the effects of financial insecurity on social interactions despite consistently observed income effects on social capital and a growing recognition of the potential importance of income volatility in affecting hardships, distress, and other aspects of well-being. We use data on women participating in a longitudinal study in the U.S. to investigate the effects of financial insecurity measured along two dimensions (safety nets and hardships) on two types of social interactions (participating in community organizations and having close friends). In auxiliary analyses we explore the potential mediating effects of mental health. We find that safety nets in the form of bank accounts, credit cards, and ability to borrow money increase both participation in organizations and friendships, whereas material hardships decrease friendships but increase participation in organizations. We find no evidence that mental health, as we have measured it, mediates the observed effects of financial insecurity on social interactions, although it has strong and negative independent associations with having close friends.

Comparing social contact and group identification as predictors of mental health
Fabio Sani et al.
British Journal of Social Psychology, forthcoming
Abstract:
Current research on social integration and mental health operationalizes social integration as frequency of interactions and participation in social activities (i.e., social contact). This neglects the subjective dimension of social integration, namely group identification. We present two studies comparing the effect exerted by social contact and group identification on mental health (e.g., depression, stress) across two different groups (family; army unit), demonstrating that group identification predicts mental health better than social contact.

The effect of hours of work on social interaction
Henry Saffer & Karine Lamiraud
Review of Economics of the Household, June 2012, Pages 237-258
Abstract:
Increases in hours of work per capita over past 30 years have created an intuitively plausible notion that there now is less time for social interaction. The purpose of this paper is to empirically investigate the effect of hours of work on social interaction. The empirical work is complicated by the argument that unobserved factors could increase both hours of work and social interaction. The empirical work in this paper employs an exogenous decline in hours of work in France due to a new employment law to bypass this endogeneity problem. The data employed are derived from the 1999-2003 Continuous Survey of Household Living Conditions which is a random sample of French households. Gender specific results from a difference-in-difference model show that the employment laws reduced hours of work but there is no evidence that the extra hours went to increased social interactions. Contrary to the intuitive argument, the paper concludes that in the range of approximately 94 extra hours of leisure per year, hours of work have no effect on social interaction.

Reducing Competitive Victimhood in Kosovo: The Role of Extended Contact and Common Ingroup Identity
Luca Andrighetto et al.
Political Psychology, forthcoming
Abstract:
During intractable conflicts, "competitive victimhood" refers to the subjective belief that one's own ingroup has suffered more than the outgroup. Although competitive victimhood is considered an important inhibitor of reconciliation processes, no research has attempted to examine ways of reducing it. The present study aims to fill this gap. Kosovar Albanians students (N = 170) were asked to report their perception of ingroup and outgroup victimhood during the protracted violence between Serbs and Albanians in Kosovo. Our findings revealed that frequent and high-quality extended contact with outgroup members and identification with a common ingroup reduced competitive victimhood. The effects of extended contact and common ingroup identification were fully mediated by increased perspective taking and trust toward the outgroup, and by decreased outgroup infrahumanization. The implications of these results for restoring fractured intergroup relations are discussed.

Altruism in social networks: Evidence for a ‘kinship premium'
Oliver Curry, Sam Roberts & Robin Dunbar
British Journal of Psychology, forthcoming
Abstract:
Why and under what conditions are individuals altruistic to family and friends in their social networks? Evolutionary psychology suggests that such behaviour is primarily the product of adaptations for kin- and reciprocal altruism, dependent on the degree of genetic relatedness and exchange of benefits, respectively. For this reason, individuals are expected to be more altruistic to family members than to friends: whereas family members can be the recipients of kin and reciprocal altruism, friends can be the recipients of reciprocal altruism only. However, there is a question about how the effect of kinship is implemented at the proximate psychological level. One possibility is that kinship contributes to some general measure of relationship quality (such as ‘emotional closeness'), which in turn explains altruism. Another possibility is that the effect of kinship is independent of relationship quality. The present study tests between these two possibilities. Participants (N= 111) completed a self-report questionnaire about their willingness to be altruistic, and their emotional closeness, to 12 family members and friends at different positions in their extended social networks. As expected, altruism was greater for family than friends, and greater for more central layers of the network. Crucially, the results showed that kinship made a significant unique contribution to altruism, even when controlling for the effects of emotional closeness. Thus, participants were more altruistic towards kin than would be expected if altruism was dependent on emotional closeness alone - a phenomenon we label a ‘kinship premium'. These results have implications for the ongoing debate about the extent to which kin relations and friendships are distinct kinds of social relationships, and how to measure the ‘strength of ties' in social networks.

Neighborhood Connections, Physical Disorder, and Neighborhood Satisfaction in Las Vegas
Andrea Dassopoulos et al.
Urban Affairs Review, forthcoming
Abstract:
This study helps to disentangle the mutual effects of neighborhood disorder and social cohesion on how residents evaluate their neighborhoods. We draw upon data from the 2009 Las Vegas Metropolitan Area Social Survey to understand how neighborhood cohesion, physical disorder, and perceptions of crime and safety influence neighborhood satisfaction and neighborhood quality of life among residents in the dynamic, yet understudied, urban context of Las Vegas, Nevada. We use ordinary least squares and binary logistic regression to predict two measures of neighborhood satisfaction. Our results show that even with significant neighborhood disorder, social connectedness with neighbors remains a significant predictor of neighborhood satisfaction. We discuss implications of neighborhood satisfaction research for other fast-changing metropolitan areas.

Hot or not? Thermal reactions to social contact
Amanda Hahn et al.
Biology Letters, forthcoming
Abstract:
Previous studies using thermal imaging have suggested that face and body temperature increase during periods of sexual arousal. Additionally, facial skin temperature changes are associated with other forms of emotional arousal, including fear and stress. This study investigated whether interpersonal social contact can elicit facial temperature changes. Study 1: infrared images were taken during a standardized interaction with a same- and opposite-sex experimenter using skin contact in a number of potentially high-intimate (face and chest) and low-intimate (arm and palm) locations. Facial skin temperatures significantly increased from baseline during the face and chest contact, and these temperature shifts were larger when contact was made by an opposite-sex experimenter. Study 2: the topography of facial temperature change was investigated in five regions: forehead, periorbital, nose, mouth and cheeks. Increased temperature in the periorbital, nose and mouth regions predicted overall facial temperature shifts to social contact. Our findings demonstrate skin temperature changes are a sensitive index of arousal during interpersonal interactions.

Social Forces, forthcoming
Abstract:
After 25 years of intense scrutiny, social capital remains an important yet highly debated concept in social science research. This research uses data from youth and mentors in several chapters of Big Brothers/Big Sisters to assess the importance of different mentoring relationship characteristics in creating positive outcomes among youths. The literature on social capital suggests that key characteristics are: (1. the amount of time spent between individuals, (2. racial similarity, (3. level of trust, (4. social class difference, and (5. intergenerational closure. I examine the effects of these social capital measures on academic and deviant behavioral outcomes and run models using propensity score weights to address selection bias. The results indicate that both the amount of time spent in a relationship and the level of trust consistently have positive effects for youths. Counter to what some theory suggests, race-matching and closure between parent and mentor have limited effects, and social class difference between individuals has no significant effect on any of the examined outcomes. These findings have important implications for future work on social capital and adolescent relationships in general.

Social Network Changes and Life Events Across the Life Span: A Meta-Analysis
Cornelia Wrzus et al.
Psychological Bulletin, forthcoming
Abstract:
For researchers and practitioners interested in social relationships, the question remains as to how large social networks typically are, and how their size and composition change across adulthood. On the basis of predictions of socioemotional selectivity theory and social convoy theory, we conducted a meta-analysis on age-related social network changes and the effects of life events on social networks using 277 studies with 177,635 participants from adolescence to old age. Cross-sectional as well as longitudinal studies consistently showed that (a) the global social network increased up until young adulthood and then decreased steadily, (b) both the personal network and the friendship network decreased throughout adulthood, (c) the family network was stable in size from adolescence to old age, and (d) other networks with coworkers or neighbors were important only in specific age ranges. Studies focusing on life events that occur at specific ages, such as transition to parenthood, job entry, or widowhood, demonstrated network changes similar to such age-related network changes. Moderator analyses detected that the type of network assessment affected the reported size of global, personal, and family networks. Period effects on network sizes occurred for personal and friendship networks, which have decreased in size over the last 35 years. Together the findings are consistent with the view that a portion of normative, age-related social network changes are due to normative, age-related life events. We discuss how these patterns of normative social network development inform research in social, evolutionary, cultural, and personality psychology.

Emotion, forthcoming
Abstract:
Social anxiety is associated with low positive affect (PA), a factor that can significantly affect psychological well-being and adaptive functioning. Despite suggestions that individuals with high levels of social anxiety would benefit from PA enhancement, the feasibility of doing so remains an unanswered question. Accordingly, in the current study, individuals with high levels of social anxiety (N = 142) were randomly assigned to conditions designed to enhance PA (Kind Acts), reduce negative affect (NA; Behavioral Experiments), or a neutral control (Activity Monitoring). All participants engaged in the required activities for 4 weeks and completed prepost questionnaires measuring mood and social goals, as well as weekly email ratings of mood, anxiety, and social activities. Both the prepost and weekly mood ratings revealed that participants who engaged in kind acts displayed significant increases in PA that were sustained over the 4 weeks of the study. No significant changes in PA were observed in the other conditions. The increase in hedonic functioning was not due to differential compliance, frequency of social activities, or an indirect effect of NA reduction. In addition, participants who engaged in kind acts displayed an increase in relationship satisfaction and a decrease in social avoidance goals, whereas no significant changes in these variables were observed in the other conditions. This study is the first to demonstrate that positive affect can be increased in individuals with high levels of social anxiety and that PA enhancement strategies may result in wider social benefits. The role of PA in producing those benefits requires further study.

Prosocial tendencies predict friendship quality, but not for popular children
Astrid Poorthuis et al.
Journal of Experimental Child Psychology, forthcoming
Abstract:
Is prosocial behavior a prerequisite for having good-quality friendships? This study (N = 477, mean age = 12.2 years) examined whether the link between children's prosocial tendencies and their perceived friendship quality was dependent on children's level of popularity in the peer group. Children's prosocial tendencies were assessed both as observed behavior in a standardized setting and as a self-reported predisposition to act in prosocial ways. Across measures, the results showed that prosocial tendencies are associated with higher perceived friendship quality among nonpopular children (i.e., children holding average or lower levels of popularity), but not among popular children. Thus, even if they lack prosocial qualities, popular children are still able to hold good-quality friendships. Popular children may have other compensating characteristics, such as popularity by association, that make them attractive for peers to be friends with.

Structure, Identity, and Solidarity: A Comparative Field Study of Generalized and Direct Exchange
Robb Willer, Francis Flynn & Sonya Zak
Administrative Science Quarterly, March 2012, Pages 119-155
Abstract:
Here we propose an account of the link between exchange structure and the emergence of solidarity capable of accounting for the conflicting evidence social scientists have found regarding the relationship between social exchange structures and the emergence of intangible, affectively laden group sentiments. We argue that benefits received through exchange foster group identification and solidarity but that this effect is stronger in generalized exchange systems - in which giving and receiving of resources occurs unilaterally among three or more individuals - than direct exchange systems - which feature reciprocal transfers of resources between two people. At low levels of benefit to recipients, generalized and direct exchange systems will produce similarly low levels of group identification. At high levels of benefit, however, generalized exchange will result in relatively higher levels of identification. Higher levels of identification leads individual members in turn to view the group as higher in solidarity. We find support for this mediated moderation model in two survey-based case studies of organizations designed to facilitate these forms of exchange: one of Freecycle, a large-scale, online generalized exchange system, the other of Craigslist, a comparable direct exchange system. The results further suggest that generalized exchange is likely to emerge where a critical mass of exchange benefits creates positive sentiments toward the group, sentiments that help fuel further contributions in the exchange system.

Shoes as a Source of First Impressions
Omri Gillath & Angela Bahns
Journal of Research in Personality, August 2012, Pages 423-430
Abstract:
Surprisingly minimal appearance cues lead perceivers to accurately judge others' personality, status, or politics. We investigated people's precision in judging characteristics of an unknown person, based solely on the shoes he or she wears most often. Participants provided photographs of their shoes, and during a separate session completed self-report measures. Coders rated the shoes on various dimensions, and these ratings were found to correlate with the owners' personal characteristics. A new group of participants accurately judged the age, gender, income, and attachment anxiety of shoe owners based solely on the pictures. Shoes can indeed be used to evaluate others, at least in some domains.

James O'Malley et al.
PLoS ONE, May 2012
Abstract:
Using a population-based, panel survey, we study how egocentric social networks change over time, and the relationship between egocentric network properties and health and pro-social behaviors. We find that the number of prosocial activities is strongly positively associated with having more friends, or an increase in degree, with approximately 0.04 more prosocial behaviors expected for every friend added. Moreover, having more friends is associated with an improvement in health, while being healthy and prosocial is associated with closer relationships. Specifically, a unit increase in health is associated with an expected 0.45 percentage-point increase in average closeness, while adding a prosocial activity is associated with a 0.46 percentage-point increase in the closeness of one's relationships. Furthermore, a tradeoff between degree and closeness of social contacts was observed. As the number of close social contacts increases by one, the estimated average closeness of each individual contact decreases by approximately three percentage-points. The increased awareness of the importance of spillover effects in health and health care makes the ascertainment of egocentric social networks a valuable complement to investigations of the relationship between socioeconomic factors and health.

What does being initiated severely into a group do? The role of rewards
Caroline Kamau
International Journal of Psychology, forthcoming
Abstract:
Undergoing an admission process (an initiation) can induce exaggerated feelings about a group, but there is little research about the role of rewards. This study replicated Aronson and Mills' (1959) experiment. Seventy participants underwent either a severe initiation or a mild initiation. After the initiation, about half the sample received an extrinsic reward for merely completing the task. The remaining half did not receive an extrinsic reward. This was to vary the amount of dissonance. Initiation severity and reward condition had significant, noncrossing interactions. A reward led to higher group identity than no reward, supporting Levine and Moreland's (1994) group socialization model. A severe initiation did not lead to more group identity than a mild initiation; therefore, Aronson and Mills' findings were not replicated. Interestingly, a mild initiation followed by a reward led to more group identity than a severe initiation followed by a reward. Another unexpected finding was that the extrinsic reward made no difference to group identity if the initiation was severe. Effects on ratings of the discussion were nonsignificant. Future research needs to establish how new group members ponder the severity of the admission process during the cost-benefit calculation preceding their identification with a group.

Peer Passengers: How Do They Affect Teen Crashes?
Allison Curry et al.
Journal of Adolescent Health, June 2012, Pages 588-594
Purpose: The specific mechanisms by which peer passengers increase teen drivers' crash risk are not completely understood. We aimed to provide insight on the two primary hypothesized mechanisms, distraction and promotion of risk-taking behavior, for male and female teen drivers and further for select driver-passenger gender combinations.
Methods: From the National Motor Vehicle Crash Causation Survey (2005-2007), we analyzed a nationally representative sample of 677 drivers aged 16-18 years (weighted n = 277,484) involved in serious crashes, to compare the risk of specific distraction-related and risk-taking-related precrash factors (documented via on-scene crash investigation) for teens driving with peer passengers and teens driving alone.
Results: Compared with males driving alone, those with peer passengers were more likely to perform an aggressive act (risk ratio, RR [95% confidence interval] = 2.36 [1.29-4.32]) and perform an illegal maneuver (RR = 5.88 [1.81-19.10]) just before crashing; risk taking increased regardless of passenger gender. Crash-involved males with passengers were also more likely to be distracted by an exterior factor (RR = 1.70 [1.15-2.51]). Conversely, females with passengers were more often engaged in at least one interior nondriving activity (other than conversing with passengers) (RR = 3.87 [1.36-11.06]), particularly when driving with opposite-gender passengers. Female drivers, both with and without passengers, rarely drove aggressively or performed an illegal maneuver before crashing.
Conclusions: Passengers may affect male teen driver crashes through both distraction and risk-promoting pathways, and female involvement primarily through internal distraction. Results of this and future studies investigating peer-driver interactions may guide development of passenger-related crash prevention efforts to complement already existing Graduated Driver Licensing passenger restrictions.

Own-gender imitation activates the brain's reward circuitry
Elizabeth Reynolds Losin et al.
Social Cognitive and Affective Neuroscience, forthcoming
Abstract:
Imitation is an important component of human social learning throughout life. Theoretical models and empirical data from anthropology and psychology suggest that people tend to imitate self-similar individuals, and that such imitation biases increase the adaptive value (e.g., self-relevance) of learned information. It is unclear, however, what neural mechanisms underlie people's tendency to imitate those similar to themselves. We focused on the own-gender imitation bias, a pervasive bias thought to be important for gender identity development. While undergoing fMRI, participants imitated own- and other-gender actors performing novel, meaningless hand signs; as control conditions, they also simply observed such actions and viewed still portraits of the same actors. Only the ventral and dorsal striatum, orbitofrontal cortex and amygdala were more active when imitating own- compared to other-gender individuals. A Bayesian analysis of the BrainMap neuroimaging database demonstrated that the striatal region preferentially activated by own-gender imitation is selectively activated by classical reward tasks in the literature. Taken together, these findings reveal a neurobiological mechanism associated with the own-gender imitation bias and demonstrate a novel role of reward-processing neural structures in social behavior.

Fen Xu et al.
PLoS ONE, April 2012
Background: All cultural groups in the world place paramount value on interpersonal trust. Existing research suggests that although accurate judgments of another's trustworthiness require extensive interactions with the person, we often make trustworthiness judgments based on facial cues on the first encounter. However, little is known about what facial cues are used for such judgments and what the bases are on which individuals make their trustworthiness judgments.
Methodology/Principal Findings: In the present study, we tested the hypothesis that individuals may use facial attractiveness cues as a "shortcut" for judging another's trustworthiness due to the lack of other more informative and in-depth information about trustworthiness. Using data-driven statistical models of 3D Caucasian faces, we compared facial cues used for judging the trustworthiness of Caucasian faces by Caucasian participants who were highly experienced with Caucasian faces, and the facial cues used by Chinese participants who were unfamiliar with Caucasian faces. We found that Chinese and Caucasian participants used similar facial cues to judge trustworthiness. Also, both Chinese and Caucasian participants used almost identical facial cues for judging trustworthiness and attractiveness.
Conclusions/Significance: The results suggest that without opportunities to interact with another person extensively, we use the less racially specific and more universal attractiveness cues as a "shortcut" for trustworthiness judgments.

Is Ostracism a Strong Situation? The Influence of Personality in Reactions to Rejection
Melissa McDonald & Brent Donnellan
Journal of Research in Personality, forthcoming
Abstract:
Previous research has demonstrated that ostracism from a social group generates psychological distress. As it stands, only a few previous studies have found evidence that immediate reactions to ostracism are moderated by individual differences. Using the classic Cyberball paradigm, the present research examined a comprehensive set of personality moderators and used the largest sample size to date of lab studies evaluating the effects of ostracism (N = 270). Results indicated that when personality effects were observed in the control condition, they tended to be attenuated in the exclusion condition. More broadly, however, the findings provide little evidence that negative reactions to ostracism are strongly influenced by individual differences in personality.

Organization Science, May/June 2012, Pages 743-757
Abstract:
This research investigates the relationship between virtual employees' degree of physical isolation and their perceived respect in the organization. Respect is an identity-based status perception that reflects the extent to which one is included and valued as a member of the organization. We hypothesize that the degree of physical isolation is negatively associated with virtual employees' perceived respect and that this relationship explains the lower organizational identification among more physically isolated virtual employees. In two field studies using survey methods, we find that perceived respect is negatively associated with the degree of physical isolation, and respect mediates the relationship between physical isolation and organizational identification. These effects hold for shorter- and longer-tenured employees alike. Our research contributes to the virtual work literature by drawing attention to physical isolation and the important but neglected role of status perceptions in shaping virtual employees' organizational identification. We also contribute to the literature on perceived respect by demonstrating how respect is affected by the physical context of work.

From the Cradle to the Grave: Age Differences in Attachment from Early Adulthood to Old Age
William Chopik, Robin Edelstein & Chris Fraley
Journal of Personality, forthcoming
Objective: Although attachment dynamics are thought to be important across the lifespan, relatively few studies have examined attachment processes beyond young adulthood. Extant research on age differences in attachment orientation has yielded conflicting results and interpretations. The purpose of this study was to provide a more complete picture of age-related differences in attachment anxiety and avoidance.
Method: We examined attachment anxiety and avoidance in 86,555 Internet respondents (71.8% female) ranging in age from 18 to 70.
Results: We found that attachment anxiety was highest among younger adults and lowest among middle-aged and older adults. Attachment avoidance showed less dramatic age differences overall but was highest among middle-aged adults and lowest among young and older adults. In addition, partnered individuals reported lower levels of attachment anxiety and avoidance compared to single individuals, particularly in younger and older adulthood. Women also reported slightly higher anxiety and avoidance compared to men, especially in young adulthood.
Conclusions: Findings are discussed in the context of lifespan changes in social roles, normative personality development, and emotion regulation throughout adulthood.

Abstract:
Affective changes in response to motive-relevant stimuli are a defining feature of implicit motives. We therefore expected to find an effect of individual differences in the implicit need for affiliation (nAff) on corrugator supercilii activity, an indicator of affect, when participants were confronted with nonverbal indicators of a conversational partner´s withdrawal. Participants' nAff was assessed with a Picture Story Exercise (PSE). They were then involved in an interaction with a smiling or a neutral experimenter while their corrugator activity was measured with electromyography (EMG). As expected, we found higher corrugator activity for people high in nAff compared to people low in nAff when the experimenter kept a neutral facial expression throughout the interaction but not when he/she was smiling.
