Individuals with narcissism are, by definition, self-centered, focus on self-benefit, and demonstrate less prosocial behaviors. Trusting strangers is risky, as it can result in exploitation and non-reciprocation. Thus, the trust may be antagonistic to narcissism. However, how narcissists make the choice to trust remains to be elucidated. The current study examined 44 participants (22 rated high in narcissism) playing as trustors in one-shot trust games, and their electroencephalograms were recorded. Individuals high in narcissism exhibited less trust toward strangers, especially following gaining feedback for their trust. In addition, narcissists exhibited a larger N2 following distrust and a stronger negatively-valanced difference in feedback-related negativity (dFRN) after trustee feedback. Our findings provide insights into how individuals with narcissism trust strangers. The results also shed light on the temporal course of brain activity involved in trust decision-making and outcome evaluation in individuals with narcissism.

The Dark Triad (DT), encompassing narcissism, Machiavellianism and psychopathy traits, poses significant societal challenges. Understanding the neural underpinnings of these traits is crucial for developing effective interventions and preventive strategies. Our study aimed to unveil the neural substrates of the DT by examining brain scans from 201 individuals (mean age: 32.

Research on externalizing psychopathology has relied heavily on White samples to generate core knowledge, with few studies examining variability in its components, including grandiose narcissism, across racial/ethnic groups. This preregistered (https://osf.io/n4s3f/) study addressed the following research questions: (1) Is there evidence for measurement invariance of the Narcissistic Admiration and Rivalry Questionnaire (NARQ) across racial/ethnic groups?; (2) Are there racial/ethnic group differences in (a) mean levels of the two NARQ subscales: admiration and rivalry, and (b) correlations between NARQ subscales and self-esteem?; (3) Do variations in ethnic identity commitment account for any observed group differences in the mean levels and correlations? The sample consisted of 1,248 U.

Consistent evidence has documented the cross-sectional and longitudinal associations of externalizing psychopathology with personality and behavioral traits, suggesting the presence of a broad, underlying liability to externalizing. In one of the first studies of its kind, we use a large, representative sample of youth ( = 2,245 twins and their siblings) to evaluate the evidence of an externalizing spectrum model, which includes psychopathology, personality, and behavioral traits and spans normal and pathological variation. We examine evidence for the inclusion of 15 candidate traits, from the domains of general and pathological personality, temperament, and aggression, in a model that includes dimensions of common childhood externalizing psychopathology.

Background: In medicine, empathy refers to a predominantly cognitive attribute (rather than an emotional one), which is important as a foundation for positive physician-patient relationships. Physicians with a narcissistic personality trait have an assortment of characteristics that undermine their interpersonal functioning in clinical encounters with their patients. Evidence suggests an inverse relationship between empathy and certain characteristics of a narcissistic personality trait in general population.

The Hypersensitive Narcissism Scale (HSNS) is a an economical, widely used self-report measure of vulnerable narcissism. Developed and mostly used as a unidimensional scale, previous structural examinations suggest two correlated dimensions, one emphasizing hypersensitive/neurotic aspects and the other highlighting egocentric/antagonistic aspects of vulnerable narcissism. The few extant factor analyses of the HSNS, however, differ profoundly in their methodological approach, the resulting item-to-factor assignment, and lack a thorough validation of the two putative subscales.
