One widely employed paradigm in this field of experimental economic games is the prisoner's dilemma-used to examine competitive versus cooperative behaviour. In the present study a prisoner's dilemma game was administrated to individuals (N = 320), along with measures of grandiose narcissism, vulnerable narcissism and impulsivity. Specifically, our results show that vulnerable narcissism has a significant positive effect on defecting behaviors, while grandiose narcissism has a significant positive effect on cooperation in the initial round. However, while the game proceeded, grandiose narcissism started to have a positive effect on defecting behaviors too. This suggests that grandiose narcissists have, at least initially, positive qualities to them which can make them popular, but in the long run they lose their positive reputation and their likeability and willingness to cooperate decrease.

Over 400 items relating to four types of discounting were generated. Next, a study followed by a series of psychometric analyses of data obtained from a group of 2843 individuals was conducted. Principal Component Analysis yielded a four-factor structure of data, reflecting the four types of discounting. The results of Confirmatory Factor Analysis showed good fit of the four-factor model to data. Through several iterations of retaining and deleting items on the basis of their component loadings, item intercorrelations, and contribution to coefficient alphas, the total number of items was reduced to 48. The final 48-item version of the inventory has satisfactory psychometric characteristics, including Cronbach's alpha and test-retest stability. In addition, significant correlations were observed between the DI and traditional discounting instruments, suggesting that the DI measures a construct similar to the behavioral discounting process. The development of the tool was based on the assumption that discounting is a personality trait. However, the present data suggest that discounting may reflect more a state than trait function.
