The transfer of social threat learning to decision making is robust to extinction.

Abstract

Through traditional mass media and online social media, we are almost constantly exposed to second-hand experiences of trauma and violence, providing ample opportunities for us to learn about threats through social means. This social threat learning can influence instrumental decision making through a social learning to decision-making transfer process, resembling the so-called Pavlovian to instrumental transfer effect, resulting in consequences that can be maladaptive. Here, we assessed if this influence could be diminished by extinction learning, a procedure where a previously threatening stimulus is learned to be safe, and thereby mitigate possible maladaptive consequences. To this end, we recruited 251 participants to undergo a social threat learning procedure (where they observed someone else receive electric shocks to one out of two images), followed by either a social or direct extinction procedure (in which no shocks were given), before conducting an instrumental decision-making task to measure the strength of the transfer effect. Based on theoretical considerations and previous literature, we proposed two competing hypotheses: (a) extinction learning would diminish the transfer effect or (b) the transfer effect would be robust to extinction. Our results clearly demonstrate that the social to instrumental transfer effect is remarkedly robust to extinction, supporting the second hypotheses. Irrespective of whether extinction was carried out through direct experience or social means, learning about threats through second-hand aversive experiences strongly influence instrumental behavior, suggesting that potentially maladaptive effects of social threat learning are challenging to diminish.
