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.

Interleukin-6 responses to acute stress are not altered in alcohol use disorder despite elevated baseline inflammation

This study examines IL-6 responses to acute stress in individuals with alcohol use disorder (AUD) and finds no difference compared to healthy controls, despite elevated baseline inflammation.

Self-compassion is linked to positive affect and buffers declines in self-esteem in low performers

The paper examines how self-compassion affects positive affect and self-esteem, finding it buffers declines in self-esteem for low performers and predicts higher positive affect.

Self-esteem modulates beneficial causal attributions in the formation of novel self-beliefs

This study examines how self-esteem and depression influence causal attributions and self-belief formation through a computational model of learning.

No neurobehavioral evidence for reduced motivational potential of social rewards in alcohol use disorder

This study finds no evidence of reduced motivation for social or monetary rewards in individuals with alcohol use disorder using neuroimaging and behavioral tasks.

Prior expectations about own abilities bias self-belief formation and hinder subsequent revision

This study shows that initial expectations bias self-belief formation and hinder their revision even when feedback contradicts them.

Time-of-day related fluctuations of self-belief formation

The paper examines how time-of-day affects self-belief formation through computational modeling of learning behavior in healthy participants.

Altered physiological, affective, and functional connectivity responses to acute stress in patients with alcohol use disorder

This study examines altered physiological, affective, and functional connectivity responses to acute stress in individuals with alcohol use disorder compared to controls.

Aberrant insula activity to negative and reduced learning from positive prediction errors as mechanisms underlying maladaptive self-belief formation in depression

The paper investigates how depression affects self-belief formation through altered neural responses to positive and negative feedback.

Neurocomputational mechanisms of affected beliefs

This study investigates how affect and neural activity influence the formation of self-efficacy beliefs through computational modeling and neuroimaging.

Association of stress-related neural activity and baseline interleukin-6 plasma levels in healthy adults

This study links baseline interleukin-6 plasma levels to neural stress responses in healthy adults, finding negative associations in specific brain regions.

Self-beneficial belief updating as a coping mechanism for stress-induced negative affect

The paper investigates how self-related belief updating helps manage stress-induced negative affect after social-evaluative stress, showing it improves recovery compared to physical stress or no stress.

Selective REM-Sleep Suppression Increases Next-Day Negative Affect and Amygdala Responses to Social Exclusion

This study shows that suppressing REM sleep increases negative affect and amygdala responses to social exclusion the next day, but not emotional regulation through reappraisal.

The Pursuit of Pride: Outcomes achieved under Beliefs of Internal Control shape positive Affect and neural Dynamics in the vmPFC

The paper shows that believing in internal control increases self-evaluative affect and neural activity in the vmPFC, leading to preferences for control.
