Can mere visuals of trauma heighten stress and trigger post traumatic stress disorder?
A recent US study suggests that there is a great deal of psychological impact that occurs due to constant and repeated exposure to violence through digital and traditional media.
A survey of 4675 US adults conducted after the 15 April attacks and the manhunt that was launched for one suspect, Tamerlan Tsarnaev, left a deep impact on viewers.
Even those that were not directly connected with the incident were affected emotionally. "Media exposure was a stronger predictor of acute stress response than having been there," experts said.
"It wasn't that the direct exposure was not important, it was just that above and beyond having been there, media exposure was an even stronger predictor of acute stress response. It doesn't become PTSD until the characteristic problems go on for more than six weeks and interfere in some significant way with people's lives. People should be aware there is no psychological benefit to repeated exposure to pictures of horror."
