How they work
CPT
Core mechanism: Identifying and challenging stuck points (distorted trauma-related beliefs) restores balanced appraisals of safety, trust, power, esteem, intimacy
Ontology: Trauma disrupts pre-existing beliefs or generates distorted accommodations about self and world
Prolonged Exposure
Core mechanism: Repeated imaginal and in-vivo exposure to trauma-related stimuli activates fear structure and provides corrective information
Ontology: Fear structure with pathological associations; avoidance prevents emotional processing

What each assumes — and misses
CPT
Philosophical roots: Beck (cognitive model); Horowitz (stress response theory); Piaget (accommodation/assimilation); constructivism (meaning is actively constructed)
Blind spots: Cognitive focus may underemphasize somatic and emotional processing; structured protocol can feel rigid
Therapeutic voice: You wrote that the assault was your fault because you didn't fight back. Let's look at that stuck point together.
Prolonged Exposure
Philosophical roots: Foa & Kozak (emotional processing theory); Lang (fear structure); Craske (inhibitory learning update); empiricist tradition
Blind spots: Dropout rates are significant; not suited for unstabilized clients; may underemphasize relational and meaning dimensions
Therapeutic voice: I want you to close your eyes and tell me what happened, in the present tense, as if it's happening right now.
Choosing between them
CPT and Prolonged Exposure both sit within the Cognitive-Behavioral tradition — they share a worldview about what suffering is and how change happens. Differences are more often about technique and emphasis than about underlying theory.
