“…Cognitive models of PTSD development and maintenance [Brewin, 2001; Brewin, Dalgleish, & Joseph, 1996; Ehlers & Clark, 2000] highlight the role of pre‐trauma vulnerability factors such as prior trauma exposure, peri‐trauma factors such as an overwhelming fear response, visual, and detail focused processing (particularly of sensory features), and post‐trauma factors such as negative/catastrophic appraisals, rumination, suppression, avoidance, and social withdrawal. Many of these risk factors are features of ASD, for example, detail focus [“weak‐central coherence”; Frith, 1989; Happé, 1999] and difficulties with social interaction [Bauminger & Kasari, 2002; Orsmond, Krauss, & Seltzer, 2004]; known to be prevalent in ASD, for example, suppression [Shipherd & Beck, 2005] and emotion dysregulation [Mazefsky, Borue, Day, & Minshew, 2014]; or associated with polygenic scores for ASD, for example, childhood trauma [Warrier & Baron‐Cohen, 2019]. Research in recently traumatized individuals with acute stress disorder has shown that when cognitive load is high, the ability to suppress memories is compromised resulting in increased traumatic intrusions (during active suppression and generally) and priming toward trauma related stimuli [Nixon & Rackebrandt, 2016].…”
