Abstract(s) :

(Anglais) Introduction. Eye-tracking-based attentional research tend to highlight a sustained attention to emotional information in posttraumatic stress disorder (PTSD). However, most of this research employed controversial tasks (such as the dot-probe) and only negatively-valenced stimuli, which tend to orient the results. Furthermore, those experiments were performed on samples that did not include both trauma-exposed healthy participants and non-trauma-exposed participants. Here, using an established eye tracking paradigm, we explore attention processes to neutral, positive and negative cues. Methods. PTSD patients (n=15, still collecting), trauma-exposed healthy controls (TEHC; n=37), and healthy controls (HC; n = 30) performed a Face in the Crowd paradigm in which 81 matrices were presented. Each matrix comprised nine different identities presenting either the same emotion (happy, neutral, angry), or in which one identity presented a different emotion (i.e. the intruder). The participants were required to identify as quickly as they can the intruder. One-third of the matrices (i.e., 27) were target-absent trials composed of only one type of emotional expression (i.e., nine trials each of matrices that were all neutral, all happy or all angry faces).
