The Discussion on the Experience Effect in the Construction of Ability of Psychological Immune

When people encounter major traumatic life events for the first time,their emotional activities behave more strongly and the time of adapting and attributing to normal last longer;but when people encounter similar events again,their ups and downs of emotion are unlikely and the adaptation time last shorter relatively.At the same time,their sensitivity to events will reduce.It is because people obtained "experience" or understanding about the events after the first traumatic event.When people encounter these traumatic events again,these "experience" and understanding can play a guiding role,which is similar to the emergence of "immune" process in biology.
