From Self-Protection to Experiential Engagement: A State-Dependent Autonomic Model of Psychotherapy Process

Abstract

This conceptual and clinical article introduces the State-Dependent Autonomic Response Model (SDARM), a transtheoretical framework for understanding moment-to-moment client responses during psychotherapy. The model addresses a common clinical challenge: as clients approach painful emotions, attachment injuries, traumatic memories, maladaptive schemas, or other forms of core suffering, their responses may shift in ways that make therapeutic work difficult. They may criticize themselves or others, argue, search for someone to blame, overanalyze, intellectualize, change the subject, become preoccupied with abstract psychological, philosophical, spiritual, or social explanations, fall silent, experience mental blankness, withdraw, become numb, or lose access to emotional and bodily experience. Different psychotherapy traditions describe these phenomena using constructs such as dysfunctional thoughts, cognitive distortions, rumination, resistance, defense mechanisms, experiential avoidance, self-criticism, process markers, coping modes, self-interruption, or protective parts. Although each of these concepts can be clinically valuable, the large number of approach-specific classifications may leave therapists uncertain about the client’s immediate position in relation to painful experience and about the most appropriate next therapeutic step. SDARM offers a simplified preliminary map that can be used before applying school-specific formulations. Rather than interpreting an isolated thought, emotion, behavior, silence, or bodily reaction in itself, the model examines the broader organization and function of the client’s response. It proposes four provisional response directions: Fight or confrontation, in which the person attempts to oppose, control, criticize, blame, defeat, or suppress the perceived source of danger; Flight or distancing, in which the person increases distance from painful experience through avoidance, excessive analysis, abstraction, rapid problem-solving, topic changes, humor, psychological explanation, or other forms of cognitive and relational movement away from immediate experience; Shutdown, characterized by reduced activation, hopelessness, withdrawal, mental blankness, silence, numbness, diminished agency, bodily collapse, or loss of access to emotion and language; and Experiential engagement, supported by sufficient autonomic regulation, in which the person can remain connected to bodily sensation, emotion, present reality, personal agency, and the therapeutic relationship while approaching painful material. Fight, flight, and shutdown are conceptualized as self-protective directions, rather than as defects, resistance, or deliberate noncompliance. Their function may be to regulate proximity to an experience that is perceived, at that moment, as dangerous, overwhelming, shameful, or intolerable. Experiential engagement does not mean constant calmness or the absence of intense emotion. A client may cry, feel anger, or experience fear while remaining experientially engaged if bodily awareness, relational contact, reflective capacity, and meaningful choice remain sufficiently available. The model is informed by Polyvagal Theory and broader research on autonomic regulation, stress, emotion regulation, therapeutic presence, and interpersonal coordination. However, it does not claim that any particular behavior provides a direct or definitive marker of a specific neural pathway. Autonomic organization is treated as a dynamic and testable clinical hypothesis that must be inferred through multimodal observation. Relevant information may include the content and function of thoughts, speech, silence, respiration, vocal rate and prosody, facial expression, gaze, muscular tension, gesture, posture, movement, client-reported bodily sensations, temporal changes during the session, and the therapist’s own embodied and relational responses. No single sign is considered diagnostically sufficient. A central contribution of SDARM is the distinction between technique-led practice and state-led practice. When therapists become preoccupied with selecting the correct intervention, challenging a defense, correcting a thought, eliciting emotion, or “fixing” the client, their own anxiety and sympathetic activation may increase. This can lead to pursuit, pressure, premature interpretation, mechanical empathy, withdrawal, or reciprocal escalation. The model therefore proposes that therapists first observe their own autonomic organization and action tendencies, recover sufficient regulatory flexibility, and strengthen therapeutic presence and relational safety. From this position, co-regulation may reduce the client’s need for protection and make a state-congruent intervention more effective. The manuscript positions SDARM in relation to cognitive therapies, psychodynamic psychotherapy and ISTDP, Emotion-Focused Therapy, Internal Family Systems therapy, schema therapy, and Somatic Experiencing. It is not intended to replace the formulations or techniques of these approaches. Instead, it offers an orienting layer that asks three immediate clinical questions: Where is the client in relation to pain? What protective function is the current response serving? What conditions might make experiential contact safer and more tolerable? The article also presents testable propositions and outlines a multimodal psychotherapy-process research program. Future studies could combine video and audio coding with client and therapist self-reports, respiration, heart rate and heart-rate variability, electrodermal activity, facial-action coding, gaze, voice analysis, posture, movement, and dyadic time-series methods. These studies could examine whether the proposed response organizations can be reliably identified, whether therapist regulation predicts recovery of experiential engagement, and whether state-led interventions improve alliance, client agency, rupture repair, retention, emotional processing, and clinical outcomes. This manuscript is a conceptual model and scholarly working paper. SDARM has not yet been validated as a diagnostic system, observational coding instrument, or evidence-based treatment protocol. The proposed categories are probabilistic, overlapping, context-sensitive, and open to empirical revision. The paper is shared to support theoretical discussion, clinical reflection, model refinement, collaborative research, and future empirical testing.
