Cet outil s'appuie sur PubMind

PubMind est une plateforme collaborative de veille scientifique qui permet d'importer des publications depuis PubMed, de suivre leur avancement de lecture, d'en extraire les éléments méthodologiques clés (protocoles, variables, résultats) et de constituer une synthèse structurée afin de faciliter la réalisation de revues de littérature. Entièrement personnalisable, cet outil s'adapte aux thématiques de recherche de ses utilisateurs.

Nous l'avons configuré ici pour centraliser et analyser la littérature scientifique concernant les croyances, les traitements psychologiques, l'étude de la scrupulosité, ainsi que l'impact et la prise en charge des troubles liés aux dérives sectaires.

Résumé

Magical ideation refers to beliefs about causality that lack empirical bases. Few studies have investigated the neural correlates of magical thinking and religious beliefs. Here, we investigate the association between magical ideation and religious experience in a sample of Vietnam veterans who sustained penetrating traumatic brain injury (pTBI) and matched healthy controls (HCs). Scores on the Magical Ideation Scale were positively correlated with scores on the Religious Experience Scale, but only in pTBI patients. Lesion mapping analyses in subgroups of pTBI patients indicated that prefrontal cortex (PFC) lesions were associated with increased magical ideation scores and this relationship was mediated by religious experience. Our findings clarify the mechanism by which the frontal lobe processes modulate magical beliefs. Suppression of the PFC opens people to religious experiences, which in turn increases magical ideation.
