The present paper contributes to the analysis and understanding of post-traumatic stress disorder from the perspective of Husserlian phenomenology. The particular approach taken integrates the experience of a ptsd trigger into Husserl’s descriptive framework of noematic constitution. By analyzing the constituent makeup of a particular object that acts as a trigger for ptsd symptoms, a descriptive account of how an ordinary noematic correlate becomes a pathological traumatic correlate is provided. This is done in three steps. First, the traumatic correlate is (...) shown to emerge by way of a judgment. Then, the role of the Ego will be examined to identify the point where the intentional relation between sufferer and traumatic correlate becomes pathological. Third, a phenomenological description of belief characteristics indicates the mechanism by which this pathology is maintained. I conclude by showing the connection between a phenomenological account of ptsd triggers and the current therapeutic practice of prolonged exposure therapy. (shrink)
