Study shows similarities between people with aggressive and psychopathic tendencies

People with more aggressive and psychopathic tendencies adopt hostile behaviors quickly, but they find it difficult to abandon these behaviors when they are no longer adaptive or practical. Although this was already suspected, a study published in the journal Translational Psychiatry confirms this hypothesis for the first time, thanks to an extensive mathematical methodology applied to a task that measures hostile responses explicitly. The study has been led by experts from the Individual Differences Lab (IDLab) research group at the Faculty of Psychology and the Institute of Neurosciences of the University of Barcelona (UBNeuro).
