The impact of narratives on human psychology ranges widely from what events we remember most easily to our choices about important foundational behaviors to include our degree of trust in others. Since the brain is the proximate cause of our actions, narratives have a direct impact on the neurobiological processes of both the senders and receivers of them. Understanding how narratives inform neurobiological processes is critical if we are to ascertain what effect narratives have on the psychology and neurobiology of human choices and behaviors, and can assist in everything ranging from exploring how Post-Traumatic Stress Disorder is influenced by event repetition to better understanding the thoughts and feelings of others.
