Michael Telch, a psychology professor from UT, is on the road to figuring out who’s going to go all John Rambo.
Perhaps the biggest insight came from the eye-tracking test. Before deployment, Telch asked soldiers to look at a panel of four faces while a computer monitored the soldiers’ eye movements. In the panel the soldiers saw a happy face, a sad face, a fearful face, and a neutral face. The soldiers who quickly averted their gaze from the fearful face—looked away within 100 milliseconds of seeing the photo—were far more likely to develop PTSD after deployment, the study found.
They’ve tested soldiers’ panic response, by having them inhale oxygen laced with 35 percent carbon dioxide; those who lose their nerve appear to be more likely to develop PTSD.
From the Boston Globe. There’s some stuff towards the end about giving high-risk-for-PTSD guys “easy” military jobs–it doesn’t make sense–but the predictability is interesting.
