All behaviors in Sensory Processing
ASMR Response
Autonomous Sensory Meridian Response — a tingling, scalp-down, parasympathetic-tinged felt-sense triggered by specific quiet stimuli such as whispered voices, slow gestures, close attention, and gentle repetitive sounds, present in roughly twenty percent of people in measurable form.
ASMR Tolerance
The gradual blunting of the ASMR response after repeated or compulsive use, in which previously reliable triggers stop producing tingling or calm, prompting the loop-runner to seek louder, longer, or more novel stimuli to reproduce the original effect.
Auditory Overload
A bandwidth-failure state specific to the hearing channel — overlapping voices, mechanical hum, mid-range hiss, traffic — where incoming sound exceeds the system's capacity to sort signal from background, and the Threat System routes the body toward shutdown.
Chromesthesia
A specific form of synesthesia in which sound — particularly music, but also voices, ambient noise, and individual pitches — automatically and reliably triggers the experience of colour, often arriving as moving light, hue, or texture in the visual field or the mind's eye.
Frisson
The brief pleasurable shiver that runs along the spine, scalp, or arms at a peak aesthetic moment — a chord change, a line of poetry, a sudden recognition — when the Meaning System confirms that something has landed.
Goosebump Trigger
The specific stimulus — a chord, a vista, a memory, a cold breeze, a sudden fear — that activates the pilomotor reflex and raises the small hairs on the arms, neck, or scalp, often signalling that something has crossed an aesthetic or autonomic threshold.
Gustatory Sensitivity
A heightened reactivity to taste and oral texture — bitterness, spice, slime, grit, mixed mouthfeel — where the nervous system rejects certain foods with a speed and certainty that looks like preference but operates closer to a protective reflex.
Highly Sensitive Person Profile
A constitutional trait — present in roughly fifteen to twenty percent of people — characterised by deeper processing of stimuli, easier overstimulation, stronger emotional reactivity, and finer sensing of subtleties, first formalised by Elaine Aron as Sensory Processing Sensitivity.
Hyperacusis
A reduced tolerance to sound at intensities that most people find comfortable, where ordinary noise — a door closing, water running, a phone ringing — registers as painful, threatening, or physically intolerable, often following hearing damage or prolonged threat exposure.
Interoceptive Numbness
A quiet disconnection from the body's interior — hunger, fatigue, emotion, thirst, fullness — where the felt signals that would orient a regulated life have become faint, late, or routed through external proxies rather than felt directly.
Interoceptive Sensitivity
A heightened awareness of the body's interior signals — heartbeat, breath, gut, temperature, tension — where ordinary internal events register as loud, urgent, and worth checking against the question *is something wrong with me right now?*
Misophonia
A sensory-emotional condition in which specific, often soft sounds — chewing, sniffing, pen-clicking — trigger a disproportionate rage or panic response, as if the brain had wired a particular auditory pattern directly into the threat circuitry.
Number-Form Synesthesia
A form of synesthesia, first described by Francis Galton in 1881, in which numbers and ordered sequences — dates, months, years, the alphabet — occupy specific, stable positions in space, forming a personal spatial geometry that the synesthete sees or feels alongside the sequence itself.
Olfactory Sensitivity
A heightened detection of and response to ambient smells — perfumes, cooking, cleaning products, body odours — where the nervous system reads scents most people barely notice as urgent information and recruits low-grade vigilance throughout the day.
Proprioceptive Seeking
A nervous system's quiet, repeated request for deep pressure, weight, joint compression, or muscular load — the kind of input that produces a felt sense of having edges, having a body, being held by something.
Sensory Avoidance
A defensive pattern in which the body pulls away from specific sensory inputs — lights, sounds, textures, smells, crowds — because the Threat System has classified those inputs as costly or dangerous, often correctly, sometimes preemptively.
Sensory Diet
An intentional daily portfolio of sensory inputs — proprioceptive, vestibular, tactile, auditory, visual — distributed across the day to keep the nervous system inside its window of tolerance, originally a clinical occupational-therapy framework now widely adopted by adults.
Sensory Hypersensitivity
A baseline calibration of the nervous system in which sensory thresholds are set low — sounds register louder, lights register brighter, fabrics register sharper — producing both a finer perceptual life and a more easily-taxed bandwidth.
Sensory Hyposensitivity
A baseline calibration of the nervous system in which sensory thresholds are set high — input has to be louder, brighter, hotter, or more emphatic to register — so the body often reaches for amplified contact to feel present in its own life.
Sensory Overload
A state in which the nervous system's incoming signal exceeds its current processing bandwidth — light, sound, touch, and movement arriving faster than the body can sort them — and the Threat System begins to treat the room itself as the danger.
Sensory Processing Disorder
A recognised clinical pattern in which the nervous system organises sensory information atypically — over-responding, under-responding, or seeking input across multiple channels — to a degree that meaningfully shapes daily life, often present alongside but distinct from autism.
Sensory Re-Engagement
The careful, titrated return to sensory contact after a period of withdrawal — light first, then sound, then touch, then social engagement — restoring the body's capacity to inhabit the world without re-triggering the overload that called the withdrawal in the first place.
Sensory Regulation Strategies
The specific moves — cold water, deep pressure, slow breathing, rhythmic movement, dim light, weighted blanket — that an individual uses to shift their nervous system back into the window of tolerance, ideally matched to the signal the body is actually sending.
Sensory Resetting
The deliberate practice of returning the sensory system to baseline — cold water, a dark room, a slow walk in nature, a stretch of silence — to clear the accumulated input load and restore the body's capacity to register signal cleanly.
Sensory Seeking
An active orientation toward strong, varied, or intense sensory input — bass, speed, spice, pressure, novelty — that the body uses either as integrated nourishment or, when chronic and untracked, as a substitute for the feeling of being alive.
Sensory Soothing
The use of gentle sensory input — warmth, soft texture, low light, slow music, a familiar scent — to settle an activated nervous system into a calmer state, integrative when matched to a real need and shallow when run as a substitute for rest the system actually needs.
Sensory Underload
A state in which the nervous system's incoming signal is too sparse to feel alive in — a low-key emptiness in the body's input layer that the Meaning System tries to plug with substituted stimulation rather than actual contact.
Sensory Withdrawal States
Periods when the nervous system retreats from sensory contact — dim light, low sound, no touch, no engagement — sometimes a necessary protective shutdown after overload, sometimes a default the system has settled into long after the original overload has passed.
Synesthesia
A neurological trait in which stimulation of one sense reliably and automatically produces an experience in another — letters carrying colours, sounds carrying shapes, numbers occupying positions in space — present in roughly four percent of people and stable across the lifetime.
Tactile Defensiveness
An unusually strong protective response to ordinary touch — clothing tags, light brushes, certain textures — where the nervous system reads neutral contact as a small threat and recruits avoidance before the conscious mind has weighed in.
Vestibular Seeking
A nervous system's recurring pull toward motion, spinning, swinging, rocking, or rapid speed change — input from the inner ear that produces a felt sense of aliveness the rest of the day seems to misplace.
Visual Overload
A bandwidth-failure state in the visual channel — flickering screens, dense signage, tight patterns, mixed light temperatures, fast motion — where the eyes are still working but the brain has stopped being able to compose what they bring in.
