Personality Traits and Psychology

Self-enhancement and devaluation of others during belief formation are linked to narcissistic traits

This study links narcissistic traits to self-enhancement and devaluation of others during belief formation using computational modeling and behavioral experiments.

Deviation from typical brain activity during naturalistic stimulation is related to personality traits

The paper examines the relationship between personality traits and brain activity using naturalistic fMRI data, finding that higher Neuroticism/Harm Avoidance is associated with lower typicality in brain activity.

Narcissistic and Antisocial Personality Traits are both encoded in the Triple Network: Connectomics evidence

This study investigates the neural basis of narcissistic and antisocial traits using connectome-based analyses, finding shared and distinct patterns in the triple network.

Longevity or Well-being? A Dual-Dimension Structure of Neuroticism

The paper proposes that neuroticism variability can be structured into two dimensions, one linked to longevity and the other to well-being, with distinct neural and genetic underpinnings.

Narcissus reflected: gray and white matter features joint contribution to the default mode network in predicting narcissistic personality traits

This study uses machine learning to identify brain networks involving gray and white matter that predict narcissistic personality traits and validates their generalizability.

Gray Matter Differentiation Between Two Subordinate Personality Traits of Extraversion: Enthusiasm and Assertiveness

The paper examines the neural basis of two subordinate extraversion traits, finding a significant interaction in the left angular gyrus between enthusiasm and assertiveness.

The Big Five personality traits and CNS arousal in the resting state

"The Heidelberg Five" Personality Dimensions: Genome-wide Associations, Polygenic Risk for Neuroticism, and Psychopathology 20 Years after Assessment

The paper identifies genetic associations with five personality dimensions and links them to psychiatric symptoms over time.

Little Evidence for Associations Between the Big Five Personality Traits and Variability in Brain Gray or White Matter

The paper tests associations between Big Five personality traits and brain structure variability in 1,107 students, finding only a weak and inconsistent link between conscientiousness and superior temporal gyrus surface area.
