Deciding to defect: the effects of video-game violence on cooperative behavior.

This experiment examined the effect of video-game violence on cooperative decision making. Participants (N= 48) were randomly assigned to play either a violent or a nonviolent version of the video game Doom in dyads. Following the video-game task, participants were separated and given an opportunity to choose to cooperate with their partner for mutual gain, withdraw from the interaction, or exploit their partner for their own benefit. Participants in the violent condition were significantly more likely to choose to exploit their partners than participants in the nonviolent condition. These findings suggest that playing violent video games may undermine prosocial motivation and promote exploitive behavior in social interactions.

You can't always get what you want: effortful control and children's responses to undesirable gifts.

This study examined individual differences in children's regulation of emotional expression after receiving desirable and undesirable gifts. Effortful control, the ability to suppress a dominant response in favor of a subdominant one, was measured using a battery of behavioral tasks. Reactions to the gifts were videotaped, and emotional expression was coded. Age predicted effortful control, but not emotional displays. Effortful control predicted similarity of children's displays of positive affect after receiving the two gifts. Specifically, children high in effortful control showed similar amounts of positive affect after receiving the desirable and undesirable gifts, whereas children low in effortful control showed less positive affect after receiving the undesirable gift than after receiving the desirable gift. Results are discussed in terms of temperament and the development of socially appropriate expressive behavior.

Emotional expression in cyberspace: searching for moderators of the Pennebaker disclosure effect via e-mail.

Research has shown that writing about emotional topics can positively influence physical and mental health. The current study tested the efficacy of an e-mail-based writing treatment and shows how such an implementation can aid in the search for moderators. Participants (N = 546) were randomly assigned to either a long- or short-interval traumatic writing condition or to a nonemotional writing control condition. In contrast to previous disclosure research, participants received and submitted their writing responses via e-mail. Health outcomes were assessed weekly for 5 weeks after treatment and were reported at the conclusion of the study. Results supported the effectiveness of an e-mail-based writing treatment in producing positive health outcomes and successfully identified several moderators of the writing treatment effect. The moderators implicated varied depending on the nature of the health outcome assessment.

Personality development: an introduction toward process approaches to long-term stability and change in persons.

This special issue is concerned with the systematic transformation of persons and personalities as they move through their lives. The focus is on developmental processes early in the life course that influence both long-term stability and change. Contributors represent diverse topics and viewpoints, but offer new data on classical issues of personality, including trait structure, self-regulation and internalization, self-evaluation, and self-efficacy. In addition, the issue includes empirical contributions on newer approaches to bullying, developmental processes in psychopathology, the influence of racial and ethnic discrimination on subsequent adjustment, and cultural influences on personality development. The issue also includes a special contribution addressing methodological and statistical advances in dealing with prospective longitudinal data assessing personality over time.

Self-esteem, personality and achievement in high school: a prospective longitudinal study in Texas.

This research explored four empirical questions: (1) Is self-esteem a better predictor of academic success and adjustment than other aspects of personality? (2) How is self-esteem related to Big-Five dimensions of personality during the transition from middle school to high school? (3) Do dispositions like Agreeableness or Openness relate to an adolescent's adaptation and affect reactions to the self? and (4) Do sources of information about adolescents (e.g., self-rating, other rating, objective "life history") converge? We also explored the general hypothesis that personality, self-esteem, and teachers' ratings of adjustment during the middle school years predict later life outcomes during high school. Overall, results indicate Big-Five personality characteristics were more stable than self-esteem across this transition period. Agreeableness and Openness assessed in middle school are related to later scholastic competence and behavioral conduct, academic success, and adjustment in high school. Results were discussed in terms of personality development and self-evaluation.

Agreeableness: dimension of personality or social desirability artifact?

Agreeableness is linked to socially valued traits and prosocial motives, so self-reported Agreeableness may be distorted by self-favoring biases (SFB). A three-study multimethod research program explored links between the Big Five dimension of Agreeableness and SFB from three perspectives. First, we examined zero-order relations between Agreeableness and SFB measures (N = 316). Next, we used a round robin design (N = 351) and the Social Relations Model analyses (Kenny, 1994) to partition perceptions of Agreeableness into target and perceiver effects. These effects then were related to SFB concerns, and differential responsiveness to a manipulation of the social desirability of Agreeableness. Study 3 (N = 312) examined a manipulation of Agreeableness as a moderator of the relation between dispositional Agreeableness and interpersonal conflict tactics. Overall, results indicate that Agreeableness is not easily manipulated nor distorted by SFB. Results are discussed in terms of Agreeableness as a substantive system of motives.
