The ability to participate in meaningful daily activities — school, play, self-care, social interaction — is the primary goal of most pediatric behavioral and therapeutic services. Yet for many children, particularly those with autism spectrum disorder or sensory processing differences, participation is limited not by skill deficits alone but by undetected or unmanaged interoceptive challenges. Interoception — the sense that informs us about our internal body state — is the invisible variable in many participation difficulties, shaping motivating operations, emotional regulation, and adaptive behavior in ways that standard observational assessment may not capture.
Abigail Hamilton's course provides clinicians with the knowledge base and practical tools to assess and address interoceptive challenges within pediatric caseloads. For behavior analysts, the significance of this content lies in its relevance to a major explanatory gap in ABA practice: why do some clients who have mastered all prerequisite skills still fail to engage in target activities? Why do behaviors that appear escape-maintained show inconsistent patterns that do not respond to standard antecedent interventions?
The answer, in a meaningful proportion of cases, is that an interoceptive variable — unrecognized discomfort, undetected arousal, failure to perceive the physiological signal of an emotion building — is functioning as the true establishing operation for the behavior. This course equips clinicians to recognize and address this variable in ways that are aligned with both the behavioral and occupational therapy knowledge bases.
The cross-disciplinary nature of this course, which offers 0.1 AOTA CEUs, reflects the practical reality that most pediatric behavior analysts work alongside OTs regularly. Understanding the OT framework for interoception enriches collaboration and produces better integrated care.
Interoception research has accelerated significantly over the past decade, with neuroscientific, developmental, and clinical studies converging on its importance for emotional regulation, social cognition, and adaptive behavior. The basic neuroscience: the body continuously sends signals from internal organs and tissues to the brain via the vagus nerve and other pathways. The insular cortex integrates these signals and produces conscious awareness of internal states — the phenomenology of feeling hungry, tired, anxious, or in pain.
Developmental research has shown that interoceptive awareness is not innate but develops through experience. Caregiving interactions — in which caregivers label and respond to infants' internal states — play an important role in building the neural pathways that support interoceptive awareness. For children who have had disrupted caregiving, or whose neurodevelopment affects sensory processing, this developmental process may be atypical.
Research on autism spectrum disorder has documented that interoceptive atypicality is common, with many autistic individuals reporting difficulty detecting and identifying internal body sensations. This finding has clinical implications that extend well beyond the domain of OT: if a learner cannot detect hunger, they may not eat appropriately; if they cannot detect the physiological signature of anxiety, they cannot access coping strategies early enough to prevent behavioral escalation; if they cannot detect the need to use the bathroom, toilet training will be persistently difficult.
For behavior analysts, the behavioral research tradition on biological MOs provides a well-established framework for integrating these findings. Biological establishing operations — internal physiological states that increase the reinforcing value of specific stimuli — are a standard part of the MO taxonomy. Interoceptive difficulty can be understood as impaired access to the information needed to identify which biological MO is currently active, resulting in behavior that is driven by internal states the learner cannot clearly perceive or communicate.
When conducting functional behavior assessments on pediatric clients with suspected interoceptive difficulties, behavior analysts should consider extending the standard indirect and direct assessment methods to explicitly probe for biological establishing operations. The ABC data collection format can be supplemented with columns recording physiological state information: time since last meal, hours of sleep the previous night, health status, and observed behavioral indicators of heightened arousal at session start.
This data enrichment does not require specialized training — it requires only the deliberate decision to track these variables alongside standard antecedent information. Over time, patterns often emerge: a learner who is consistently more dysregulated at sessions scheduled before lunch, or whose behavior escalation is more frequent when arriving from a sensory-intense environment, is displaying a signature that points to interoceptive variables as functionally relevant.
Intervention at the antecedent level is often the first line of response when interoceptive MOs are identified. Scheduling sessions in ways that minimize adverse physiological states (not before meals for food-deprived learners, not immediately following high-sensory-load activities) reduces the establishing operation before a behavioral problem occurs. This is a simpler and faster intervention than teaching interoceptive labeling, and it can stabilize the treatment context while more complex skill-building is in progress.
For longer-term intervention, helping learners develop interoceptive labeling skills — the ability to detect, identify, and communicate internal states — is the most durable solution. This skill-building can be incorporated into existing ABA programs as a form of verbal behavior instruction: tacting internal states is a verbal operant that can be taught through standard prompting and reinforcement procedures, with the addition of structured interoceptive awareness activities recommended by OT literature.

Code 2.01 of the BACB Ethics Code requires behavior analysts to practice within their competence and to refer to other professionals when client needs require it. For clients with significant interoceptive challenges, this means being transparent about the limits of behavior-analytic methods for addressing sensory processing concerns and actively facilitating OT involvement when indicated. Attempting to address interoceptive challenges using only behavioral procedures, without the sensory processing framework that OTs bring, may produce incomplete treatment.
Code 3.01 on assessment requires that behavior analysts use scientifically validated methods appropriate to the presenting concerns. For clients where biological MOs are clearly operating but standard FBA methods are not producing a clear functional picture, expanding assessment to include interoceptive probes and requesting interdisciplinary assessment is consistent with this standard.
Assent and consent are particularly important in interoception-focused intervention because some activities (body scan exercises, activities designed to produce specific physiological sensations) may be experienced as uncomfortable or anxiety-provoking, especially for learners with trauma histories or significant sensory sensitivity. Caregivers must be fully informed about the nature of these activities, and learner assent should be sought at the appropriate communication level. Activities should be designed to be gradually graded in intensity and should always be presented within a context of safety and learner control.
The principle of individualized assessment (Code 3.02) is especially relevant here: interoceptive profiles vary significantly across individuals, and intervention approaches should be tailored to the specific interoceptive challenges identified through assessment. Generic 'sensory strategies' applied without individualized assessment data are inconsistent with both ethical and evidence-based practice standards.
A clinical decision framework for incorporating interoception into pediatric assessment begins with three screening questions: Does the learner have a history of sensory processing differences identified by an OT? Does the FBA show behavioral patterns consistent with biological MOs (e.g., behavior consistently worse before meals, after physical exertion, or in high-sensory environments)? Do caregivers report that the learner has difficulty detecting or communicating internal states?
If any of these screens are positive, a more structured assessment of interoceptive awareness is warranted. For behavior analysts without OT training, this means requesting an OT consultation and sharing the behavioral data that prompted the referral. For behavior analysts working in settings without OT access, a caregiver-completed interoceptive history interview — asking specifically about the child's awareness of hunger, fatigue, pain, temperature, and emotional physical sensations — can provide useful indirect information.
Within-session assessment can include brief probes before and after interoceptive awareness activities: asking the learner to indicate (through any available communication modality) how their body feels before a session, tracking this rating over time, and examining whether days on which the learner reports low-arousal states are associated with higher performance and lower problem behavior frequency.
Decision rules for escalating to OT referral should be specified in advance. A reasonable threshold is: if behavioral variability cannot be explained by the identified function across three or more consecutive treatment plan review cycles, and biological MO explanations are plausible based on pattern data, an OT referral is clinically indicated. Documenting this reasoning in the clinical record supports both ethical accountability and continuity of care.
Clinicians who integrate interoceptive awareness into their clinical frameworks are better equipped to explain — and address — the behavioral variability that resists standard intervention approaches. This does not require becoming an interoception specialist; it requires incorporating a specific set of assessment questions, observational strategies, and collaborative practices into existing workflows.
The most impactful practice change is simple: start tracking physiological state variables in FBA and session data. Add fields for time since last meal, sleep quality (reported by caregiver), health status, and observed indicators of pre-session arousal to existing data collection tools. This requires no new assessment training and immediately enriches the dataset available for functional analysis.
Building stronger referral relationships with OTs on shared caseloads is another high-leverage action. Many behavior analysts and OTs work with the same clients but conduct their sessions independently, comparing notes only in brief team meetings. Scheduling periodic joint observation sessions — in which the OT and BCBA observe the same session together and discuss what they see from each framework — produces insights that neither discipline generates working alone.
For direct care staff and RBTs, brief training on interoception concepts — framed in accessible language — helps them notice and document the behavioral signals of interoceptive distress before escalation occurs. Teaching staff to recognize early behavioral indicators (increased self-stimulatory behavior, changes in facial expression, proximity-seeking or avoidance) as possible signals of interoceptive distress gives them more information with which to make in-session decisions. This enriches the data flow back to the supervising BCBA and the broader treatment team.
