Bottom-up processing enters the depth-psychology corpus primarily through the somatic and trauma-treatment literature, where it functions as a counterpoint — and corrective — to the dominance of cognitively mediated, insight-oriented therapies. Levine stakes the most philosophically ambitious claim: bottom-up processing is ontologically prior, rooted in our identity as 'motor creatures' who sense and act before they think, inverting the Cartesian premise on which most Western psychotherapy rests. Ogden and her collaborators develop the clinical architecture most systematically, mapping bottom-up processes to subcortical and sensorimotor levels of a tripartite brain model and arguing for bidirectional integration with top-down cognition as the therapeutic ideal. Winhall extends this framework into addiction treatment via the Felt Sense Polyvagal Model, drawing on Gendlin's felt-sense phenomenology to position bottom-up processing as the somatic foundation for genuine change. Siegel and Barrett approach the term from neuroscientific angles — predictive processing and interoceptive hierarchies — reframing bottom-up signals as prediction-error inputs that continuously revise top-down priors. A persistent tension runs through the corpus: bottom-up processing is simultaneously celebrated as the royal road to embodied transformation and cautioned against when, unchecked by cortical regulation, it produces dysregulation, flooding, or subcortical 'hijacking' of executive function. The term thus names both a therapeutic method and a neurobiological phenomenon whose clinical leverage depends entirely on its calibrated relationship with top-down governance.

Bottom-up processing is more potent than top-down processing in altering our basic perceptions of the world. This potency derives from the fact that we are first and foremost motor creatures.
Levine grounds bottom-up processing in a somatic ontology that reverses Cartesian primacy of thought, arguing that sensation, action, and feeling precede and outweigh cognitive reflection in shaping fundamental perception.
Levine, Peter A., In an Unspoken Voice: How the Body Releases Trauma and Restores Goodness, 2010thesis
Top-down and bottom-up processing represent two directions of information flow, and their interplay holds significant implications for the occurrence and treatment of trauma.
Ogden theorizes bottom-up processing as one axis of a bidirectional information-flow model, arguing that effective trauma therapy requires the clinician to identify and work at the level — sensorimotor, emotional, or cognitive — most productive at each therapeutic moment.
Ogden, Pat, Trauma and the Body: A Sensorimotor Approach to Psychotherapy, 2006thesis
Bottom-up interventions... similarly, bottom-up interventi[ons]... if such interventions overmanage, ignore, suppress, or fail to support adaptive body processes, these traumatic responses may not be resolved.
Ogden argues that bottom-up interventions targeting sensorimotor experience are indispensable to trauma resolution, but warns that exclusive reliance on either top-down or bottom-up strategies alone is insufficient.

In seeking a bottom-up approach to the study of addiction, I found myself exploring more of Gendlin's writings... the struggle to integrate top-down (logical and objective) and bottom-up (felt dimension of experiencing) processing.
Winhall, drawing on Gendlin's phenomenology, frames bottom-up processing as the felt-sense dimension of experience and positions its integration with top-down logic as the central challenge of addiction therapy.

Awareness of how information processing occurs will help clients to understand how bottom-up therapy works. HIJACKING OF YOUR NEOCORTEX explores how the triggering of subcortical reactions can interfere with cortical functioning.
Ogden presents bottom-up therapy as an educational framework in which clients learn to recognize subcortical hijacking of cortical function, reframing symptoms as neurobiological events rather than personal failures.
Ogden, Pat, Sensorimotor Psychotherapy Interventions for Trauma and, 2015thesis
The systems that develop first influence the 'wiring' of both bottom-up and top-down processes and, in turn, strongly influence action systems that develop subsequently.
Ogden situates bottom-up processing within a developmental framework, showing how early attachment relationships shape subcortical regulatory circuits before cortical top-down governance becomes available.

Impulsive clients can be helped to decrease shame and put their impulsivity into better perspective if they understand that bottom-up 'hijacking' by the subcortical brains (Goleman, 1995) results in the loss of neocortical monitor[ing].
Ogden applies the concept of bottom-up subcortical hijacking therapeutically, arguing that psychoeducation about this mechanism reduces shame and enables clients to reframe impulsivity as a neurobiological rather than moral failing.

Unanticipated information is a prediction error signal that tracks the difference between the prediction and the actual incoming input from the world and the body (also known as 'bottom up' signal).
Siegel, integrating predictive coding theory, recasts bottom-up signals as prediction-error inputs — discrepancies between expected and actual sensory data — that continuously revise the brain's top-down anticipatory models.

The cognitive behavioural therapy (CBT) model flourished... Its emphasis is on changing the client's 'maladaptive' cognitions in order to change behaviour. The trouble, it seems, is all in our heads.
Winhall positions CBT as a paradigmatic top-down approach and implicitly contrasts it with bottom-up somatic methods, arguing that cognition-first models neglect the body's primacy in signalling safety and regulating the autonomic nervous system.

She tried to tell herself everything was OK, but this top-down attempt to manage her subcortical responses did not quie[t them].
Ogden illustrates through clinical vignette the insufficiency of top-down self-talk when subcortical bottom-up responses have been activated, demonstrating the practical necessity of somatic intervention.

Dysregulated arousal may drive a traumatized person's emotional and cognitive processing, causing emotions to escalate, thoughts to spin, and misinterpretation of present environmental cues as those of a past trauma.
Ogden describes the pathological dominance of bottom-up sensorimotor dysregulation in trauma, wherein subcortical arousal overwhelms and distorts higher cognitive and emotional processing.

A 'paradigm shift' is indicated in psychotherapy... that takes into account the dominance of nonverbal, body-based, implicit processes over verbal, linguistic, explicit processes.
Ogden frames the turn toward body-based, bottom-up clinical methods as a necessary paradigm shift, grounded in Schore's evidence for right-hemisphere and implicit-process dominance in human behavior.

polyvagal model: a bottom-up approach / Jan Winhall.
Winhall's foundational framing names the Felt Sense Polyvagal Model explicitly as a bottom-up approach, establishing the book's entire clinical framework as an application of somatic, body-first processing to addiction and trauma.

Sensorimotor processing refers to experiencing, articulating, and integrating physical/sensory perception, body sensation, physiological arousal, and motor functioning.
Ogden defines sensorimotor processing as the practical clinical correlate of bottom-up processing, distinguishing it from emotional processing and arguing that their differentiation is therapeutically essential in trauma work.

Important components of traumatic events are encoded and processed at a subcortical level... aspects of previous traumatic experience are confused with current reality.
Ogden establishes the subcortical encoding of trauma as the neurological basis for bottom-up interventions, noting that somatic remembering — sensations, autonomic responses, involuntary movements — bypasses and distorts cognitive processing.

Prediction signals (also known as 'top down') are embodied, whole-brain representations that continuously anticipate... Unanticipated information is a prediction error signal... (also known as 'bottom up' signal).
McGovern, drawing on predictive processing and the Free Energy Principle, situates bottom-up signals within a Jungian-neuroscientific synthesis, framing subcortical prediction errors as the neurological substrate through which archetypal content achieves salience.

A sensory representation is thought to have a minimal amount of categorization; that is, input is registered in the brain with relatively little 'top-down' processing.
Siegel distinguishes raw sensory registration — bottom-up input with minimal categorical processing — from top-down perceptual categorization, providing the neurobiological architecture underpinning the clinical bottom-up/top-down distinction.
