EXTRAVERSION

Personality and Socialization

Extraversion is a personality characteristic associated with sociability, impulsiveness and aggression. Extraversion has also been linked to physiological factors. Studies on twins have found that extraversion and introversion have a genetic component.

How individual differences in Extraversion and Agreeableness affect cooperation in an experimental resource dilemma. Extraversion was generally negatively related to cooperation, whereas Agreeableness was generally positively related to cooperation. Whereas individuals high in Extraversion and individuals low in Agreeableness were unresponsive to feedback regarding collective resource use, individuals low in Extraversion and individuals high in Agreeableness exercised more self-restraint when the common resource was severely threatened.

Exploratory analyses revealed neither interactive effects of Extraversion and Agreeableness nor effects of individual differences in Conscientiousness, Emotional Stability, and Intellect. Together, these results highlight the importance of individual differences in Extraversion and Agreeableness in social dilemma settings. - Sander L.

This paper compares the Hebrew editions of the Extraversion, Neuroticism and Lie Scales of the short form EPQ-R with the longer and more established indices of the EPQ among a sample of 190 female trainee teachers in Israel.

Putting Personality in Social Context: Extraversion, Emergent Leadership, and the Availability of Rewards - Lorne Campbell, University of Western Ontario, Jeffry A. Simpson,  John Manning, Texas A&M University, Mark Stewart, Southern Methodist University - Personality and Social Psychology Bulletin, Vol. 29, No. 12, 1547-1559 (2003)
The present research tested relations between extraversion and emergent leadership among men in situations that differed in potential reward availability. Four-person groups of men engaged in a Leaderless Group Discussion (LGD) task and were randomly assigned to be evaluated by an attractive female observer, an attractive male observer, or not be evaluated. Evolutionary theories suggest that impressing a female evaluator in a competitive situation should hold greater reward potential for men than impressing either a male evaluator or no evaluator. Extraversion should play a key role and more extraverted men should display more group leadership when being evaluated by a woman than either a man or no one. Self-and peer ratings confirmed that more extraverted men were significantly more likely to emerge as leaders, but only in the female-evaluator condition.

The Big Five Inventory (BFI) is a self-report measure designed to assess the high-order personality traits of Extraversion, Agreeableness, Conscientiousness, Neuroticism, and Openness.

The Multifactorial Nature of Extraversion-Introversion in the Myers-Briggs Type Indicator and Eysenck Personality Inventory - Gary J. Sipps, Ralph A. Alexander, The Univ of Akron, Educational and Psychological Measurement, Vol. 47, No.3
The study was designed to test the construct validity of extraversion-introversion and to explore the nature of the concept as measured by the Myers-Briggs Type Indicator (MBTI) and the Eysenck Personality Inventory (EPI). The psychometric properties of the MBTI have been inadequately studied, whereas those of the EPI have been investigated extensively. Responses to the two measures were submitted in toto to factor analysis. Of the seven factors retained, three measures of extraversion appeared. Findings supported the view of extraversion-introversion as a complex construct (Eysenck and Eysenck, 1977; Guilford, 1977; Howarth, 1976). The Myers-Briggs Type Indicator - Extraversion Introversion (MBTI-EI) and the Myers-Briggs Type Indicator-Judging Perceiving (MBTI-JP), scales were found, surprisingly, to be factorially valid measures of impulsivity/non-planning.

The role of conscientiousness and extraversion in affecting the relationship between perceptions of group potency and volunteer group member selling behavior: An interaction perspective - Mitchell Neubert, Baylor University, Simon Taggar, Wilfrid Laurier University, Steven Cady, Bowling Green State University, Human Relations, Vol. 59, No. 9, 1235-1260 (2006)
We studied 284 volunteers, loosely coupled in groups (i.e. low task interdependence, high outcome interdependence), selling memberships in a non-profit organization. Consistent with economic models of altruism, we found individual perceptions of group potency to be negatively related to individual selling behavior. Furthermore, individual members’ perceptions of group potency were found to interact with two personality traits (conscientiousness and extraversion) to influence individual selling behavior.

Research Note: Personality and Music Preference: Extraversion and Excitement Seeking or Openness to Experience? Stephen J. Dollinger, Dept. of Psychology, Southern Illinois Univ.
Psychology of Music, Vol. 21, No. 1, 73-77 (1993) © 1993 Society for Education, Music, and Psychology Research
The NEO Personality Inventory and an abbreviated version of the Little and Zuckerman (1986) Music Preference questionnaire were administered to university students to test the relation of openness and extraversion to music preferences. Replicating the findings of other researchers, extraversion was positively related to one kind of music with high arousal properties (jazz), and excitement seeking to another (hard rock).
