Summary

Post-traumatic stress disorder (PTSD) is characterized by hypervigilance. In particular, previous works suggest that patients tend to scan constantly the environment for possible threats. The present project aims at investigating such attentional bias in patients with PTSD using the change blindness paradigm that offers the interesting possibility of studying sensitivity to sudden changes using ecological stimuli. More precisely, the investigators will investigate whether patients are more sensitive than matched controls to sudden changes in the visual environment and whether this hypersensitivity is specific or even stronger when visual information has an emotional content. The attentional bias will be measured using motor responses (accuracy and speed to indicate the occurrence of a change by pressing a button) as well as eye movements.
