Plane emergency landing psychology study: People with PTSD have irrelevant memories.: "What did vary among the accounts was the number of details that had nothing to do with Air Transat Flight 236 at all. After transcribing the memories, the researchers went back and coded statements as “internal” (“directly related to the main event … specific to time and place … conveying a sense of episodic re-experiencing”) and “external” (“factual information or extended events that did not require recollection of a specific time and place,” “tangential … autobiographical details,” editorializing, repetitions, metacognitive claims like “I can’t remember”). They found that passengers with PTSD produced far more external details than those without. This held true for the nonflight memories too: A survivor with PTSD was more likely to surround her nonemotional recollection with semantic data, repetition, and unrelated noise. "
