The effects that violence leaves on people directly affect their cognitive abilities even decades after they suffered it, according to an international study with the participation of the Universitat Jaume I, which has analysed the response of more than 700 people facing different types of violence in Colombia and Germany. The study published in the journal *Proceedings of the National Academy of Sciences of the USA* shows for the first time the effects of violence on short-term memory, the ability to store information and cognitive control related to the ability to concentrate and take decisions.  
  
Survivors of violence are exposed to serious consequences for their lives. To date, research on these effects has mainly focused on their consequences on the health and individual behaviour of individuals. The study led by UJI researcher Gianluca Grimalda, together with Francesco Bogliacino of the Faculty of Economics of the National University of Colombia, first established the effects of exposure to violence on the cognitive abilities of individuals. It concludes that a traumatic experience that is unresolved can negatively affect a person's ability to exert cognitive abilities even decades after the trauma has occurred. The research also included Pietro Ortoleva of Princeton University and Patrick Ring of IfW.
