Sweet taste preferences and experiences predict prosocial inferences, personalities, and behaviors
Brian Meier et al.
Journal of Personality and Social Psychology, forthcoming
Abstract:
It is striking that prosocial people are considered "sweet" (e.g., "she's a sweetie") because they are unlikely to differentially taste this way. These metaphors aid communication, but theories of conceptual metaphor and embodiment led us to hypothesize that they can be used to derive novel insights about personality processes. Five studies converged on this idea. Study 1 revealed that people believed strangers who liked sweet foods (e.g., candy) were also higher in agreeableness. Studies 2 and 3 showed that individual differences in the preference for sweet foods predicted prosocial personalities, prosocial intentions, and prosocial behaviors. Studies 4 and 5 used experimental designs and showed that momentarily savoring a sweet food (vs. a nonsweet food or no food) increased participants' self-reports of agreeableness and helping behavior. The results reveal that an embodied metaphor approach provides a complementary but unique perspective to traditional trait views of personality.

Abstract:
When banks and firms are connected through interpersonal linkages - such as their respective management having attended college or previously worked together - interest rates are markedly reduced, comparable with single shifts in credit ratings. These rate concessions do not appear to reflect sweetheart deals. Subsequent firm performance, such as future credit ratings or stock returns, improves following a connected deal, suggesting that social networks lead to either better information flow or better monitoring.

Checkbooks in the Heartland: Change Over Time in Voluntary Association Membership
Pamela Paxton & Matthew Painter
University of Texas Working Paper, August 2011
Abstract:
Numerous scholars documented declines in America's social capital through the mid-1990s but we do not know whether the trend has continued. Further, despite warnings by Robert Putnam and Theda Skocpol that the quality of Americans' voluntary association memberships has also deteriorated - moving from active, "face-to-face" memberships to passive, "checkbook" memberships - data have not been available to test this claim. In this paper, we use both the Iowa Community Survey and the General Social Survey to explore the changing nature of voluntary association membership between 1994 and 2004. We demonstrate that not only are declines in voluntary association memberships continuing in the new century but there has been a shift in the intensity of voluntary association participation over time. We observe a decline in active membership over time and an increase in checkbook membership over time. These findings provide support for Putnam's claim that checkbook membership is increasing at the expense of more active types of memberships.

The social context of trust: The role of status
Robert Lount & Nathan Pettit
Organizational Behavior and Human Decision Processes, forthcoming
Abstract:
The current paper examines how status, a universal feature of organizational life, affects people's initial trust in others. In three experiments - which employ a range of status manipulations and trust measures - we consistently observed that the possession of high status led individuals to trust others more. In addition, our results help shed light on why this occurs. Namely, mediation analyses illustrated that having status alters how we perceive others intentions, such that the belief that others have positive intentions toward us (i.e., benevolence) accounted for the relationship between status and trust. These findings contribute both to our knowledge of the contextual features which impact trust and provide insight into the psychological consequences of status.

Instant messages vs. speech: Hormones and why we still need to hear each other
Leslie Seltzer et al.
Evolution and Human Behavior, forthcoming
Abstract:
Human speech evidently conveys an adaptive advantage, given its apparently rapid dissemination through the ancient world and global use today. As such, speech must be capable of altering human biology in a positive way, possibly through those neuroendocrine mechanisms responsible for strengthening the social bonds between individuals. Indeed, speech between trusted individuals is capable of reducing levels of salivary cortisol, often considered a biomarker of stress, and increasing levels of urinary oxytocin, a hormone involved in the formation and maintenance of positive relationships. It is not clear, however, whether it is the uniquely human grammar, syntax, content and/or choice of words that causes these physiological changes, or whether the prosodic elements of speech, which are present in the vocal cues of many other species, are responsible. In order to tease apart these elements of human communication, we examined the hormonal responses of female children who instant messaged their mothers after undergoing a stressor. We discovered that unlike children interacting with their mothers in person or over the phone, girls who instant messaged did not release oxytocin; instead, these participants showed levels of salivary cortisol as high as control subjects who did not interact with their parents at all. We conclude that the comforting sound of a familiar voice is responsible for the hormonal differences observed and, hence, that similar differences may be seen in other species using vocal cues to communicate.

Jonathan Cook et al.
British Journal of Social Psychology, forthcoming
Abstract:
An experience sampling study tested the degree to which interactions with out-group members evoked negative affect and behavioural inhibition after controlling for level of friendship between partners. When friendship level was statistically controlled, neither White nor Black participants reported feeling more discomfort interacting with ethnic out-group members compared to ethnic in-group members. When partners differed in sexual orientation, friendship level had a less palliating effect. Controlling for friendship, both gay and straight men - but not women - felt more behaviourally inhibited when interacting with someone who differed in sexual orientation, and heterosexual participants of both genders continued to report more negative affect with gay and lesbian interaction partners. However, gay and lesbian participants reported similar levels of negative affect interacting with in-group (homosexual) and out-group (heterosexual) members after friendship level was controlled. Results suggest that much of the discomfort observed in inter-ethnic interactions may be attributable to lower levels of friendship with out-group partners. The discomfort generated by differences in sexual orientation, however, remains a more stubborn barrier to comfortable inter-group interactions.

Group Processes & Intergroup Relations, September 2011, Pages 703-722
Abstract:
Bullying attitudes and behaviors and perceptions of peers were assessed in a case study experiment employing a social norms intervention in five diverse public middle schools in the State of New Jersey (Grades 6 to 8). Data were collected using an anonymous online survey (baseline n = 2,589; postintervention n = 3,024). In the baseline survey, students substantially misperceived peer norms regarding bullying perpetration and support for probullying attitudes. As predicted by social norms theory, they thought bullying perpetration, victimization, and probullying attitudes were far more frequent than was the case. Also as predicted, variation in perceptions of the peer norm for bullying was significantly associated with personal bullying perpetration and attitudes. Using print media posters as the primary communication strategy, an intervention displaying accurate norms from survey results was conducted at each of the five school sites. A pre-/postintervention comparison of results revealed significant reductions overall in perceptions of peer bullying and probullying attitudes while personal bullying of others and victimization were also reduced and support for reporting bullying to adults at school and in one's family increased. The extent of reductions across school sites was associated with the prevalence and extent of recall of seeing poster messages reporting actual peer norms drawn from the initial survey data. Rates of change in bullying measures were highest (from around 17% to 35%) for the school with the highest message recall by students after a one-and-a-half-year intervention. Results suggest that a social norms intervention may be a promising strategy to help reduce bullying in secondary school populations.

Peer Effects and Multiple Equilibria in the Risky Behavior of Friends
David Card & Laura Giuliano
NBER Working Paper, May 2011
Abstract:
We study social interactions in the risky behavior of best-friend pairs in the National Longitudinal Study of Adolescent Health (Add Health). Focusing on friends who had not yet initiated a particular behavior (sex, smoking, marijuana use, truancy) by the first wave of the survey, we estimate bivariate discrete choice models for their subsequent decisions that include peer effects and unobserved heterogeneity. Social interactions can lead to multiple equilibria in friends' choices: we consider simple equilibrium selection models as well as partial likelihood models that remain agnostic about the choice of equilibrium. Our identification strategy assumes that there is at least one individual characteristic (e.g., physical development) that does not directly affect a friend's propensity to engage in a risky activity. Our estimates suggest that patterns of initiation of risky behavior by adolescent friends exhibit significant interaction effects. The likelihood that one friend initiates intercourse within a year of the baseline interview increases by 4 percentage points (on a base of 14%) if the other also initiates intercourse, holding constant family and individual factors. Similar effects are also present for smoking, marijuana use, and truancy. We find larger peer effects for females and for pairs that are more likely to remain best friends after a year. We also find important asymmetries in the strength of the peer effects in non-reciprocated friendships.

Similarity in depressive symptoms in adolescents' friendship dyads: Selection or socialization?
Matteo Giletta et al.
Developmental Psychology, forthcoming
Abstract:
This study examined friendship selection and socialization as mechanisms explaining similarity in depressive symptoms in adolescent same-gender best friend dyads. The sample consisted of 1,752 adolescents (51% male) ages 12-16 years (M = 13.77, SD = 0.73) forming 487 friend dyads and 389 nonfriend dyads (the nonfriend dyads served as a comparison group). To test our hypothesis, we applied a multigroup actor-partner interdependence model to 3 friendship types that started and ended at different time points during the 2 waves of data collection. Results showed that adolescents reported levels of depressive symptoms at follow-up that were similar to those of their best friends. Socialization processes explained the increase in similarity exclusively in female dyads, whereas no evidence for friendship selection emerged for either male or female dyads. Additional analyses revealed that similarity between friends was particularly evident in the actual best friend dyads (i.e., true best friends), in which evidence for socialization processes emerged for both female and male friend dyads. Findings highlight the importance of examining friendship relations as a potential context for the development of depressive symptoms.

Being in "Bad" Company: Power Dependence and Status in Adolescent Susceptibility to Peer Influence
Robert Vargas
Social Psychology Quarterly, September 2011, Pages 310-332
Abstract:
Theories of susceptibility to peer influence have centered on the idea that lower status adolescents are likely to adopt the behaviors of high status adolescents. While status is important, social exchange theorists have shown the value of analyzing exchange relations between actors to understand differences in power. To build on status-based theories of peer influence, this study analyzes power dependence relations in three adolescent friendship groups. Analyzing adolescent interaction as social exchange showed how being in a group with balanced power relations insulated adolescents from peer influence, even when some peers were delinquent or low academic achievers. In contrast, adolescents in groups with unbalanced power relations were particularly susceptible to peer influence. This study presents an additional way to analyze the peer influence process and illustrates the importance of applying social psychological theory to cases of micro inequality, particularly in the context of small groups.

Abstract:
People enjoy acting extraverted, and this seems to apply equally across the dispositional introversion-extraversion dimension (Fleeson, Malanos, & Achille, 2002). It follows that dispositional introverts might improve their happiness by acting more extraverted, yet little research has examined potential costs of this strategy. In two studies, we assessed dispositions, randomly assigned participants to act introverted or extraverted, and examined costs-both emotional (concurrent negative affect) and cognitive (Stroop performance). Results replicated and extended past findings suggesting that acting extraverted produces hedonic benefits regardless of disposition. Positive affect increased and negative affect did not, even for participants acting out of character. In contrast, we found evidence that acting counterdispositionally could produce poor Stroop performance, but this effect was limited to dispositional extraverts who were assigned to act introverted. We suggest that the positive affect produced by introverts' extraverted behavior may buffer the potentially depleting effects of counterdispositional behavior, and we consider alternative explanations. We conclude that dispositional introverts may indeed benefit from acting extraverted more often and caution that dispositional extraverts may want to adopt introverted behavior strategically, as it could induce cognitive costs or self-regulatory depletion more generally.

Abstract:
Symmetry on bilateral body parts indicates evolutionary fitness. Thus, traits positively associated with symmetry are thought to have conferred fitness in evolutionary history. Studies of the relationships between personality traits and symmetry have been narrow and have produced inconsistent findings. In our study, we relate both body symmetry and facial symmetry to 203 personality scales and to the Big Five. Our results demonstrate that (a) symmetry is related to personality traits beyond chance, (b) socially aversive traits, such as aggression and Neuroticism are positively related to symmetry, and (c) pro-social traits such as empathy and Agreeableness are negatively related to symmetry. Such trait levels may developmentally adjust in response to symmetry or may be inherited with symmetry (i.e., dual inheritance).

Games and Economic Behavior, September 2011, Pages 91-110
Abstract:
Extensive field evidence shows individuals' decisions in settings involving uncertainty depend on their peers' decisions. One hypothesized cause of peer group effects is social interaction effects: an individual's utility from an action is enhanced by others taking the same action. We employ a series of controlled laboratory experiments to study the causes of peer effects in choice under uncertainty. We find strong peer group effects in the laboratory. Our design allows us to rule out social learning, social norms, group affiliation, and complementarities as possible causes for the observed peer group effects, leaving social interaction effects as the likely cause. We use a combination of theory and empirical analysis to show that preferences including "social regret" are more consistent with the data than preferences including a taste for conformity. We observe spillover effects, as observing another's choice of one risky gamble makes all risky gambles more likely to be chosen.

An experimental investigation of why individuals conform
Basit Zafar
European Economic Review, August 2011, Pages 774-798
Abstract:
Social interdependence is believed to play an important role in individual choice behavior. I first outline a simple model constructed on the premise that people are motivated by their own payoff and by how their action compares to others in their reference group. I show that conformity in actions may arise from learning about the descriptive norm, or from image-related concerns. In order to empirically disentangle the two, I use the fact that image-related concerns can only be present if actions are publicly observable. The model predictions are then tested in a charitable contribution experiment in which the actions and identities of the subjects are unmasked in a controlled and systematic way. Both learning about the descriptive norm (i.e., what others are doing) and image-related concerns play an important role in the choices of the subjects. Individuals indulge in social comparison and change their contributions in the direction of the social norm even when their identities are hidden. Once identities and contribution distributions of group members are revealed, individuals conform to the choice of other group members. Moreover, I find that social ties (defined as subjects knowing each other from outside the lab) affect the role of social influence: Subjects only respond to the choices of group members they are friends with. In particular, a low contribution norm evolves that causes individuals to contribute less in the presence of friends. This suggests that social comparison and image-related concerns may not always lead to higher contributions.

Alone and Happy: Personality Moderates the Effect of Happy Mood on Social Approach
Christina Brown et al.
Journal of Research in Personality, forthcoming
Abstract:
Happy moods are believed to evoke an approach orientation and to broaden one's potential courses of action. Although positivity is strongly associated with approach, social approach is a more complex behavior because interacting with other individuals can offer either positive or negative consequences. We provide novel experimental evidence that happiness actually reduces social approach among individuals whose happiness might be threatened by social interaction. Specifically, experimentally induced mood interacted with participants' personality, such that participants who were high in social inhibition (e.g., shyness, rejection sensitivity) sat further away from another individual when in a happy mood. We suggest that happiness may produce a general orientation to approach other individuals except when such approach threatens mood.

Social constraints, genetic vulnerability, and mental health following collective stress
Alison Holman, Rachel Lucas-Thompson & Tammy Lu
Journal of Traumatic Stress, forthcoming
Abstract:
A repeat-length polymorphism of the serotonin promoter gene (5-HTTLPR) has been associated with depression and posttraumatic stress disorder (PTSD) in trauma-exposed individuals reporting unsupportive social environments. We examine the contributions of the triallelic 5-HTTLPR genotype and social constraints to posttraumatic stress (PTS) symptoms in a national sample following the September 11, 2001 (9/11) terrorist attacks. Saliva was collected by mail from 711 respondents (European American subsample n = 463) of a large national probability sample of 2,729 adults. Respondents completed web-based assessments of pre-9/11 mental and physical health, acute stress 9 to 23 days post-9/11, PTS symptoms, and social constraints on disclosure regarding fears of future terrorist attacks 2-3 years post-9/11. Social constraints were positively associated with PTS symptoms 2-3 years post-9/11. The triallelic 5-HTTLPR genotype was not directly associated with PTS symptoms, but it interacted with social constraints to predict PTS symptoms 2-3 years post-9/11: Social constraints were more strongly associated with PTS symptoms for individuals with any s/lg allele than for homozygous la/la individuals. Constraints on disclosing fears about future terrorism moderate the 5-HTTLPR genotype-PTS symptom association even when indirectly exposed to collective stress.

Homophily in stable and unstable adolescent friendships: Similarity breeds constancy
Christopher Hafen et al.
Personality and Individual Differences, October 2011, Pages 607-612
Abstract:
This study examines homophily among adolescent friends. Participants were drawn from a community-based sample of Swedish youth who ranged from 11 to 18 years old. A total of 436 girls and 338 boys identified their closest friends and described their own delinquent activities, intoxication frequency, achievement motivation, and self-worth. Correlations and difference scores describe similarity between reciprocally nominated friends on each dimension. Adolescents who remained friends from one year to the next tended to be more similar than those who did not, during the friendship and, to a lesser extent, before the friendship. Comparisons with random pairs of same-age peers revealed that age-group homophily accounts for most of the similarity between unstable friends but only a fraction of the similarity between stable friends.

Tryptophan and Interpersonal Spin
D.S. Moskowitz et al.
Journal of Research in Personality, forthcoming
Abstract:
Increased serotonergic activity is often described as increasing the inhibition of behaviors. This study examined the more general hypothesis that increased serotonergic activity produces greater control over social behavior. Participants were drawn from two samples, individuals elevated on irritability and individuals unselected on personality characteristics. Individuals participated in a double blind cross-over design, providing event contingent records about their behavior during two nine-day periods which involved taking tryptophan or placebo. When taking tryptophan (which increases serotonergic activity), within-person variability among social behaviors across events (i.e., interpersonal spin) was reduced for irritable individuals, particularly those low on trait Agreeableness. These results suggest that higher levels of serotonergic activity enhance greater control and consistency in social behavior among irritable-disagreeable individuals.
