“…This increased attentional allocation leaves insufficient resources for executive control processes (reduced top–down attentional system) to inhibit such information and relocate attentional resources towards pertinent stimuli (Eysenck, Derakshan, Santos, & Calvo, 2007 ). However, although research conducted on anxiety-related disorders has highlighted homogeneous results regarding the presence of heightened bottom–up activation (Bar-Haim, Lamy, Pergamin, Bakermans-Kranenburg, & van Ijzendoorn, 2007 ), this has not been the case for PTSD (Blekic, Wauthia, Kandana Arachchige, Lefebvre, & Rossignol, 2020 ; Cisler et al, 2011 ; Torrence & Troup, 2017 ). Therefore, studies have recently turned to the identification of a possible top–down dysfunction that could help us to understand the clinical hyperarousal observed in the daily clinical aspects of this pathology.…”
