Judge, T. A., et al (2006). Loving yourself abundantly: relationship of the narcissistic personality to self-and other perceptions of workplace deviance,…

The authors report results from 2 studies assessing the extent to which narcissism is related to self- and other ratings of leadership, workplace deviance, and task and contextual performance. Study 1 results revealed that narcissism was related to enhanced self-ratings of leadership, even when controlling for the Big Five traits. Study 2 results also revealed …

Twenge, J. M., &Campbell, W. K. (2003). “Isn’t it fun to get the respect that we’re going to deserve?” Narcissism, social rejection, and aggression.

Across four studies, narcissists were more angry and aggressive after experiencing a social rejection than were nonnarcissists. In Study 1, narcissism was positively correlated with feelings of anger and negatively correlated with more internalized negative emotions in a self-reported, past episode of social rejection. Study 2 replicated this effect for a concurrent lab manipulation of …

Penney, L. M., & Spector, P. E. (2002). Narcissism and counterproductive work behavior: Do bigger egos mean bigger problems?. International Journal of selection and Assessment, 10(1‐2), 126-134.

In accordance with the theory of threatened egotism and aggression, the relationships among narcissism, trait anger, job constraints and counterproductive work behavior (CWB) were explored in a questionnaire study. The results were supportive of the hypotheses that narcissism would relate to trait anger, job constraints, and CWB and that the relationship between narcissism and CWB …

Salmivalli, C., et al. (1999). Self-evaluated self-esteem, peer-evaluated self-esteem, and defensive egotism as predictors of adolescents’ participation in bullying situations.

Three dimensions of self-esteem (SE) (self-evaluated, peer-evaluated, defensive egotism) were related to each other and to adolescents’ social behavior. In addition to exploring links between single variables, five SE profiles were formed by means of a cluster analysis and connected to adolescents’ behavior in situations of bullying. Self-and peer-evaluated SEs were significantly correlated, whereas defensive …

Fein, S., &Spencer, S. J. (1997). Prejudice as self-image maintenance: Affirming the self through derogating others. Journal of personality and Social Psychology, 73(1), 31.

The authors argue that self-image maintenance processes play an important role in stereotyping and prejudice. Three studies demonstrated that when individuals evaluated a member of a stereotyped group, they were less likely to evaluate that person negatively if their self-images had been bolstered through a self-affirmation procedure, and they were more likely to evaluate that …

L. Fredrickson, B., &Levenson, R. W. (1998). Positive emotions speed recovery from the cardiovascular sequelae of negative emotions.

Two studies tested the hypothesis that certain positive emotions speed recovery from the cardiovascular sequelae of negative emotions. In Study 1, 60 subjects (Ss) viewed an initial fear-eliciting film, and were randomly assigned to view a secondary film that elicited: (a) contentment; (b) amusement; (c) neutrality; or (d) sadness. Compared to Ss who viewed the …

Fredrickson, B. L., Mancuso, R. A., Branigan, C., &Tugade, M. M. (2000). The undoing effect of positive emotions. Motivation and emotion, 24(4), 237-258.

Positive emotions are hypothesized to undo the cardiovascular aftereffects of negative emotions. Study 1 tests this undoing effect. Participants (n = 170) experiencing anxiety-induced cardiovascular reactivity viewed a film that elicited (a) contentment, (b) amusement, (c) neutrality, or (d) sadness. Contentment-eliciting and amusing films produced faster cardiovascular recovery than neutral or sad films did. Participants …

Berk, L. S., &Tan, S. A. (2006). [beta]-Endorphin and HGH increase are associated with both the anticipation and experience of mirthful laughter. The FASEB Journal, 20(4), A382.

Chronic stress is correlated with increases in stress hormones such as cortisol and catecholamines. This can lead to suppression of immune components. We have previously reported that humor associated mirthful laughter (a eustress, positive phenomenon that ameliorates biological effects of distress): 1) decreases “detrimental” stress hormones; 2) increases NK cell activity and 3) increases IFN-. …

Twenge, J. M., Konrath, S., Foster, J. D., Keith Campbell, W., &Bushman, B. J. (2008). Egos inflating over time: A cross‐temporal meta‐analysis of the Narcissistic Personality Inventory.

ABSTRACT A cross‐temporal meta‐analysis found that narcissism levels have risen over the generations in 85 samples of American college students who completed the 40‐item forced‐choice Narcissistic Personality Inventory (NPI) between 1979 and 2006 (total n=16,475). Mean narcissism scores were significantly correlated with year of data collection when weighted by sample size (β=.53, p<.001). Since 1982, …
