Ve zkratce
The authors describe fear as a memory structure, not a simple reflex. Exposure helps by adding information that corrects that structure. Fear that drops during and between sessions suggests processing is working.

Context
This paper is a theoretical model, not a clinical trial. Foa and Kozak published it in Psychological Bulletin in 1986. They set out to explain how emotional processing of fear actually works. They also asked why exposure helps some clients and fails with others. The paper reviews existing ideas and builds a framework from them. It draws on animal learning research and on clinical observation of anxiety treatment. The model was influential in shaping exposure-based therapy. It still remains a proposal rather than a tested result. The paper reports no new data, no sample, and no effect sizes.
Findings
The authors view emotions as information structures stored in memory. Anxiety occurs when a structure that programs escape or avoidance gets activated. Emotional processing means modifying the memory structures that underlie the emotion. The authors argue that exposure to feared situations is common to many anxiety therapies. Confrontation with feared objects or situations is an effective treatment. Two signs indicate that processing is happening. The first is bodily activation, such as a racing heart or sweating. The second is habituation, meaning the fear response gets weaker with repeated contact. Habituation can happen within one session. It can also happen across sessions, when the starting fear level drops from one session to the next. Fear must first be activated for change to occur. The authors then examine what influences activation and habituation. They conclude that three kinds of information must be integrated. These are the feared stimulus, the person's responses in the situation, and the meaning it holds for them. Treatment failures, they suggest, come from interference. Cognitive defenses, high bodily arousal, mood state, and mistaken beliefs can all block change. Each of these can keep the fear structure from being corrected.
Implications
For your practice, the model suggests exposure must genuinely activate fear. A calm conversation about a feared situation may not switch the structure on. Track fear levels within each session and across the whole course. If fear does not drop, look for what is blocking it. Check for subtle avoidance, very high arousal, low mood, or a mistaken belief. Address the meaning of the fear, not only the cues. The authors stress that exposure is not just facing a situation. It is facing information that contradicts what the client expects. The paper does not specify how many sessions are needed. It also does not say which clients will respond.
Co nepřeceňovat
This is a 1986 theoretical model, not trial evidence. It gives no effect sizes and no proof of cause. Habituation as a marker of change is proposed, not validated. The paper does not say exposure works for every client or how long it should take.
