خود شیفتگی خود بزرگ بین، خود شیفتگی آسیب پذیر و تکانشگری

Correlations between the grandiose narcissism and vulnerable narcissism with two self-report personality measures (i.e., BIS-11 and I7) and two behavioral tasks (i.e., Stop-Signal Task and Delay-Discounting task) of impulsivity in 338 students were examined. As one of the first studies to apply a two-dimensional approach to narcissism (i.e. grandiose narcissism and vulnerable narcissism) in different self-report and behavioral impulsivity measures, the present results have reported that both grandiose and vulnerable narcissism showed a significant positive correlations with the self-reported impulsivity. Moreover, the grandiose narcissism has shown significant associations with both behavioral tasks of impulsivity. Contrary, vulnerable narcissism was negatively related to the stop reaction time – people high in vulnerable narcissism scored shorter stop reaction time values and, consequently, presented less impulsive responding.
