After terrorist attacks such as the bombing in Manchester, England, where 22 people were killed, community leaders often urge people show resilience, and continue on with their daily lives, according to Roxane Cohen Silver, professor of psychology and social behavior.
But many factors determine each person's specific response. Stress symptoms, for instance, can be especially acute for those exposed to a relentless stream of violent images.
"There is variability in how people respond," Silver told The Washington Post. "There’s no one monolithic response to these kinds of events, and the individual responses depend on quite a number of factors."
