Impulsivity, time perception and non-suicidal self-injury in adolescents: from behavioral and fNIRS evidence (opens in new tab)

BackgroundElevated impulsivity and temporal processing deficits are key risk factors for adolescent non-suicidal self-injury (NSSI); however, their joint neural substrates and specific contributions to NSSI remain inadequately characterized. This study aimed to elucidate the behavioral and neural interplay between these cognitive domains in adolescents with NSSI.MethodsWe recruited 44 adolescents with NSSI and 37 typically developing (TD) controls. Participants completed the Barratt Impulsive...
