Using computational modeling, we investigated how narcissistic traits and the experience of pride are linked to how individuals form beliefs about themselves and others. Methods: Healthy individuals and individuals with psychiatric diagnoses varying in narcissistic traits (N = 97) completed a learning task in which self-serving biases emerged implicitly through trial-by-trial belief updating in response to manipulated feedback. Computational modeling quantified how participants updated beliefs about their own and another person's ","pubDate":"2026-10-26","url":"https://www.biorxiv.org/content/10.64898/2026.10.21.760328v1?rss=1"},"indexado":"2026-10-26T23:22:05.517Z"}}
