Extraversion and the ability to decode nonverbal communication

This study examined the relationship between extraversion, as measured by the Eysenck Personality Inventory (EPI), and skill at decoding nonverbal forms of communication. Prior research has had mixed success in establishing this relationship. Because extraverts have more experience in social settings than introverts, and because extraverts have a greater desire for sensory stimulation than introverts, it was hypothesized that extraverts would decode nonverbal cues in social interaction more accurately than introverts. The data supported this hypothesis. Extraverts were significantly more accurate in interpreting the meaning of nonverbal communication than introverts; in addition, extraverts were more confident that they were accurate decoders than introverts. The results are discussed in terms of cognitive processing style: the ‘extravert advantage’ in decoding nonverbal communication may be due to extraverts' superior attentive/perceptual skills; their superior interpretive/attributional skills; or both. In addition, the results are discussed in terms of methodological issues in the nonverbal decoding literature and their impact on research on extraversion. The nonverbal decoding task used in the present study differed from that of prior research by presenting scenes of natural, spontaneous, dyadic interactions for which an objective criterion for accuracy existed.     

Extraversion and reactions to cognitive inconsistency

Two studies are reported which test the hypothesis that extraverts are more tolerant of cognitive inconsistency than are introverts. The first study tested this prediction in the context of Heider's balance model. While degree of extraversion did not moderate reactions to imbalance, extraverts did show less aversion to interpersonal disagreement than introverts. When coupled with other recently published data this suggests that extraverts find arousing social situations less aversive than introverts. In support of the main hypothesis, the second experiment showed that extraverts changed their attitudes less than introverts as a result of writing an essay which was counter to their own attitude under conditions where they had high perceived freedom of choice.     

Study habits and Eysenck's theory of extraversion-introversion

Predictions derived from Eysenck's theory of personality were tested in two samples by relating extraversion scores to library study locations, frequency of study breaks, and self-report of factors which influence study location. The predicted main effects for study location were found, with extraverts occupying locations that provided greater external stimulation. Positive correlations were consistently found between extraversion and preferred level of noise, preferred level of socializing opportunities, and rated importance of socializing opportunities. The prediction that extraverts would take more frequent study breaks was supported in Sample 1 but not replicated in Sample 2. The data are interpreted as providing direct support for Eysenck's theory of behavioral differences and mixed indirect support for his theory of neurological differences between introverts and extraverts.     

Links between real and virtual networks: a comparative study of online communities in Japan and Korea.

The present study explores how online communities affect real-world personal relations based on a cross-cultural survey conducted in Japan and Korea. Findings indicate that the gratifications of online communities moderate the effects of online communities on social participation. Online communities are categorized into a real-group-based community and a virtual-network-based community. The membership of real-group-based online community is positively correlated with social bonding gratification and negatively correlated with information- seeking gratification. Japanese users prefer more virtual-network-based online communities, while their Korean counterparts prefer real-group-based online communities. Korean users are more active in online communities and seek a higher level of socializing gratifications, such as social bonding and making new friends, when compared with their Japanese counterparts. These results indicate that in Korea, personal relations via the online community are closely associated with the real-world personal relations, but this is not the case in Japan. This study suggests that the effects of the Internet are culture-specific and that the online community can serve a different function in different cultural environments.     

Gay-Straight Alliances Vary on Dimensions of Youth Socializing and Advocacy: Factors Accounting for Individual and Setting-Level Differences

Gay‐Straight Alliances (GSAs) are school‐based youth settings that could promote health. Yet, GSAs have been treated as homogenous without attention to variability in how they operate or to how youth are involved in different capacities. Using a systems perspective, we considered two primary dimensions along which GSAs function to promote health: providing socializing and advocacy opportunities. Among 448 students in 48 GSAs who attended six regional conferences in Massachusetts (59.8 % LGBQ; 69.9 % White; 70.1 % cisgender female), we found substantial variation among GSAs and youth in levels of socializing and advocacy. GSAs were more distinct from one another on advocacy than socializing. Using multilevel modeling, we identified group and individual factors accounting for this variability. In the socializing model, youth and GSAs that did more socializing activities did more advocacy. In the advocacy model, youth who were more actively engaged in the GSA as well as GSAs whose youth collectively perceived greater school hostility and reported greater social justice efficacy did more advocacy. Findings suggest potential reasons why GSAs vary in how they function in ways ranging from internal provisions of support, to visibility raising, to collective social change. The findings are further relevant for settings supporting youth from other marginalized backgrounds and that include advocacy in their mission.     

Effects of punishment on response latency in extraverts

Previous findings indicate that in comparison to introverts, extraverts are prone to form responses that are resistant to interruption by punishment. Because the tendency to stop and reflect following punishment may be crucial for subsequent learning, the present study was designed to examine differences between introverts' and extraverts' reactions to punishment using response latency on the trial following punishment as the dependent variable. Sixty-six extraverted and 66 introverted male undergraduates performed a pattern-matching task in which they received noncontingent 50% success and 50% failure feedback under three incentive conditions including reward only, punishment only, or both. As predicted, a significant interaction was found in the both condition, reflecting the tendency of extraverts to respond more quickly and introverts more slowly following punishment feedback than following reward feedback. No significant effects were found in the other two conditions; however, a tendency was noted for extraverts to respond more quickly overall when only reward was given. A second experiment using reward-only and punishment-only feedback replicated this finding and yielded a significant interaction of Group X Condition. The results indicate that in contrast to introverts, extraverts are activated by the availability of reward and, paradoxically, that punishment may facilitate rather than interrupt extraverts' reward seeking behavior.     

Extraversion and positive affect: A day reconstruction study of person–environment transactions

Extraversion is robustly correlated with positive affect, but the reasons for this correlation remain unclear. One possibility is that extraverts and introverts both enjoy interacting with others, but extraverts do so more frequently. Another possibility is that extraverts enjoy social interactions more. Both hypotheses were tested using the Day Reconstruction Method. Subjects reported on interactions with others and positive affect experienced during all of the episodes from a single day. Results were consistent with the first hypothesis: the relation between extraversion and positive affect was partially mediated by extraverts’ greater social participation. The findings support a transactional approach to personality, in which traits like extraversion are seen as styles of actively engaging with the environment.     

Do extraverts get more bang for the buck? Refining the affective-reactivity hypothesis of extraversion

One of the most robust observations in personality and emotion research is the finding that extraverts are happier than introverts. Some theorists have attributed this to differential reactivity of the brain reward system, which is central to many biologically inspired models of extraversion. This affective-reactivity hypothesis, which suggests that extraverts should be more susceptible to the induction of positive affect, has so far received very mixed empirical support. In this article, we consider a more biologically plausible account of extraverts' affective-reactivity. Over 5 experiments, we demonstrate that extraverts show greater affective-reactivity only in response to clearly appetitive stimuli and situations (e.g., where rewards are being pursued). Conversely, after merely pleasant stimuli and situations (without any reward-approach element), extraverts and introverts respond similarly. We also show that it is specifically activated affect (e.g., feelings of alertness), rather than pleasantly valenced affect (e.g., feelings of contentment), that characterizes the affective-reactivity of extraverts. Such reactions may potentially facilitate the reward-seeking behavior associated with extraversion, but they seem unlikely to explain the broadly happy disposition of extraverts.     

The influence of introversion-extraversion on activity choice and satisfaction among the elderly

The present study investigated the optimum theory of aging. This theory predicts that individuals with different personality types will react differentially to the aging process. In the present study, 60 nursing-home residents were administered the Eysenck Personality Inventory and then randomly assigned to one of two experimental manipulations. Elderly subjects classified as extraverts showed a high level of satisfaction to an experimental manipulation which was of a high activity, interpersonal type; those classified as introverts evidenced more satisfaction with a low activity, non-interpersonal type manipulation. Inspection of records documenting actual participation in programs within the nursing home indicated that introverts were more often involved in low activity, non-interpersonal events whereas extraverts participated more often in high activity, interpersonal events. Implications of these results are discussed in relation to the optimum theory of aging.     

Interpersonal movement synchrony facilitates pro‐social behavior in children's peer‐play

The emergence of pro‐social behaviors and social interaction skills is a major focus of research on children's development. Here, we consider one important feature of human social interactions, interpersonal movement synchrony, and explore its effects on pro‐sociality among young children. Coordinated movements are a crucial part of mother–infant interactions, with important social effects extending well into childhood. Musical interactions are also known to facilitate bonding between infants and caretakers and pro‐sociality among peers. We specifically examine the pro‐social effects of interpersonal movement synchrony in a naturalistic peer‐play context among 4‐ to 6‐year‐old children. We assessed the amount of helping behavior between pairs of children following an activity that they performed synchronously or non‐synchronously. Children who engaged in synchronous play, as compared with non‐synchronous play, showed significantly more subsequent spontaneous helping behavior. Further, more mutual smiling and eye contact were observed in the synchronous condition and amounts of mutual smiling and eye contact during the movement task correlated with amount of helping behavior observed. Neither measure mediated the condition‐wise effects on helping, however. These results are discussed in terms of their contribution to existing literature and their broader implications for the development of pro‐sociality and coordinated movements in early childhood.     

Associational social capital and psychological type: an empirical enquiry among cathedral Friends in England

A sample of 1131 members of the Friends associations of six English cathedrals (616 women and 515 men) completed the Francis Psychological Type Scales (FPTS) and a modified version of the Williams Religious Social Capital Index (WRSCI). The data demonstrated that higher levels of religious social capital were found among extraverts (compared with introverts), sensing types (compared with intuitive types), and feeling types (compared with thinking types). No significant differences were found between judging types and perceiving types. The finding that extraverts displayed higher levels of religious social capital poses a challenge for the cathedrals, given that introverts outnumbered extraverts by nearly 2:1 in the Friends groups. Since religious social networks are known to influence generosity with time and money, it is suggested that cathedrals not only develop strategies to recruit more extravert Friends but also devise novel ways of encouraging introvert types to participate in associational activities where social capital will be generated.     

Quality of relationships and structural properties of social support networks of female survivors of abuse

The purposes of this study were to examine the structural properties of the social support networks of female survivors of violence and abuse and to investigate the quality of the relationship, and specific level of satisfaction, survivors have with their social support networks. Participants averaged 5.8 persons in their social support networks. Their levels of satisfaction with the emotional, practical, financial, guidance, and socializing support they received from members of their social support networks were higher with respect to close friends and coworkers than with respect to family members and professionals (e.g., attorneys and social workers). The most common type of support provided by close friends who were themselves victims of abuse was emotional, guidance, and socializing support, and the most satisfying support was the financial and practical help that came from parents or family. An interesting finding was the significant presence of men in the survivors' social support networks. Overall satisfaction with the quality of support from the social support networks was high, and satisfaction with support from men was comparable, if not higher, than support from women. Multiple regression models revealed that satisfaction with support networks was a potent predictor of self-esteem, emotional health, and loneliness. Intimacy, especially in terms of exclusiveness and trust or loyalty, with at least a few members of the support network contributed significantly to the variance in self-esteem, emotional health, and loneliness among the abused women. The size of the support network also emerged as a limited contributor to well-being. Implications and applications are discussed for professionals working with female survivors of abuse.     

Toward a Science of Mood Regulation

Mood is distinguished from emotion, and mood regulation is distinguished from coping. A model of mood regulation is presented which draws on principles of control theory, which distinguishes between maximizing pleasure and minimizing psychic pain, and which emphasizes individual differences in several component subprocesses. A preliminary taxonomy of strategies and behaviors for remediating unpleasant affect is presented. Important topics for future research are discussed, including the assessment of successfulness of mood-regulation strategies, affective specificity in strategies (e.g., what works for anger might not work so well for sadness), and person specificity in strategies (e.g., socializing or helping others may be more effective strategies for extraverts than introverts). The relationship of mood regulation to overall life satisfaction and global happiness is discussed.     

The impact of Eysenck's extraversion-introversion personality dimension on prospective memory

Prospective memory (PM) is memory for future events. PM is a developing area of research (e.g., Brandimonte, Einstein & McDaniel, 1996) with recent work linking personality types and their utilisation of PM (Goschke & Kuhl, 1996; Searleman, 1996). The present study compared 28 extraverts and 28 introverts on their short- and long-term prospective memory using the Prospective Memory Scale developed by Hannon, Adams, Harrington, Fries-Dias & Gibson (1995). The main finding was that extraverts reported significantly fewer errors on short- and long-term PM than introverts, and this difference could not be explained in terms of the number of strategies used to support prospective remembering. These findings are discussed in relation to differences between the personality types.     

Parasite-stress promotes in-group assortative sociality: the cases of strong family ties and heightened religiosity

Throughout the world people differ in the magnitude with which they value strong family ties or heightened religiosity. We propose that this cross-cultural variation is a result of a contingent psychological adaptation that facilitates in-group assortative sociality in the face of high levels of parasite-stress while devaluing in-group assortative sociality in areas with low levels of parasite-stress. This is because in-group assortative sociality is more important for the avoidance of infection from novel parasites and for the management of infection in regions with high levels of parasite-stress compared with regions of low infectious disease stress. We examined this hypothesis by testing the predictions that there would be a positive association between parasite-stress and strength of family ties or religiosity. We conducted this study by comparing among nations and among states in the United States of America. We found for both the international and the interstate analyses that in-group assortative sociality was positively associated with parasite-stress. This was true when controlling for potentially confounding factors such as human freedom and economic development. The findings support the parasite-stress theory of sociality, that is, the proposal that parasite-stress is central to the evolution of social life in humans and other animals.     

Socialization of Discrete Negative Emotions: Gender Differences and Links with Psychological Distress

On the basis of Malatesta-Magai's model (Magai, 1996) of emotion socialization, parental contingent responses to expressed emotion in children were expected to facilitate (e.g., Reward, Magnify) or inhibit (e.g., Override, Neglect, Punish) the expression of various discrete emotions. In this study, retrospective reports of parental emotion socialization in childhood were reported by 322 young adult participants. Perceptions of 3 negative emotions—sadness, anger, and fear—were assessed. Using a retrospective, self-report measure, gender-based emotion socialization patterns were found across all 3 emotions, which suggests that the gender of both the parent and child influences the way in which different emotions are socialized. Young adults reported, in recalling their childhood, that mothers were more typically involved in socializing negative emotions than were fathers. For anger, mothers reportedly were the more active emotion socializing agents; they used Reward, Magnify, and Override more than did fathers. For sadness and fear, parents reportedly modified the way in which they socialized these emotions based on the gender of their child. For example, fathers reportedly rewarded girls and punished boys for expressing sadness and fear. A second aim of this study was to examine links between emotion socialization strategies and psychological distress. Perceptions of the parental emotion socializing responses of Punish and Neglect were positively correlated with psychological distress in young adults. Although certain aspects of the methodology limit conclusions, the findings of this study suggest that emotion socialization differs in girls and boys, and these differences are consistent with models that link specific parental emotion socialization approaches (e.g., punishment of negative emotions) to psychopathology—a question that deserves further exploration.     

Understanding extraverts' enjoyment of social situations: the importance of pleasantness

Extraversion is a broad, multifaceted trait, yet researchers are still unsure of its defining characteristics. One possibility is that the essential feature of extraversion is the tendency to enjoy social situations. An alternative possibility is that extraversion represents sensitivity to rewards and the tendency to experience pleasant affect. In three studies, participants rated situations that varied on two dimensions: (a) whether they were social or nonsocial and (b) whether they were very pleasant, moderately pleasant, moderately unpleasant, or very unpleasant. Extraverts only rated social situations more positively than introverts did when the situations were pleasant, and extraverts also rated nonsocial situations more positively than introverts did if the situations were pleasant. Thus, the pleasantness of situations was more important than whether they were social or nonsocial in determining extraverts' and introverts' enjoyment.     

Expectation of success following noncontingent punishment in introverts and extraverts

Recent findings indicate that extraverts are more likely than introverts to continue responding in the face of punishment and frustrating nonreward (Newman & Kosson, 1984; Tiggemann, Winefield, & Brebner, 1982). The current study investigates whether extraverts' expectations for success are, similarly, resistant to interruption and alteration. To test this hypothesis, 50 introverted and 50 extraverted male undergraduates were exposed to pretreatment with either a 50% level of noncontingent reward or a 50% level of noncontingent punishment. As predicted, there were significant Group X Pretreatment interactions on all dependent measures. In comparison to those introverts who received the punishment pretreatment, extraverts exposed to the same pretreatment placed larger wagers on their ability to succeed, and reported higher levels of perceived control. In addition, relative to their estimates for the pretreatment task, extraverts exposed to noncontingent punishment increased their expectation for success, whereas introverts exposed to noncontingent punishment decreased their performance expectations. No differences were observed between the two groups following pretreatment with noncontingent reward. The results suggest that extraverts are characterized by a distinctive reaction to punishment involving response facilitation as opposed to response inhibition.     

What do people desire in others? A sociofunctional perspective on the importance of different valued characteristics

Humans, as discriminately social creatures, make frequent judgments about others' suitability for interdependent social relations. Which characteristics of others guide these judgments and, thus, shape patterns of human affiliation? Extant research is only minimally useful for answering this question. On the basis of a sociofunctional analysis of human sociality, the authors hypothesized that people highly value trustworthiness and (to a lesser extent) cooperativeness in others with whom they may be interdependent, regardless of the specific tasks, goals, or functions of the group or relationship, but value other favorable characteristics (e.g., intelligence) differentially across such tasks, goals, or functions. Participants in 3 studies considered various characteristics for ideal members of interdependent groups (e.g., work teams, athletic teams) and relationships (e.g., family members, employees). Across different measures of trait importance and different groups and relationships, trustworthiness was considered extremely important for all interdependent others; the evidence for the enhanced importance of cooperativeness across different interdependence contexts was more equivocal. In contrast, people valued other characteristics primarily as they were relevant to the specific nature of the interdependent group or relationship. These empirical investigations illuminate the essence of human sociality with its foundation of trust and highlight the usefulness of a theoretically derived framework of valued characteristics.     

The Big Five,self-esteem,and narcissism as predictors of the topics people write about in Facebook status updates

Status updates are one of the most popular features of Facebook, but few studies have examined the traits and motives that influence the topics that people choose to update about. In this study, 555 Facebook users completed measures of the Big Five, self-esteem, narcissism, motives for using Facebook, and frequency of updating about a range of topics. Results revealed that extraverts more frequently updated about their social activities and everyday life, which was motivated by their use of Facebook to communicate and connect with others. People high in openness were more likely to update about intellectual topics, consistent with their use of Facebook for sharing information. Participants who were low in self-esteem were more likely to update about romantic partners, whereas those who were high in conscientiousness were more likely to update about their children. Narcissists’ use of Facebook for attention-seeking and validation explained their greater likelihood of updating about their accomplishments and their diet and exercise routine. Furthermore, narcissists’ tendency to update about their accomplishments explained the greater number of likes and comments that they reported receiving to their updates.
