Audio-Visual Entrainment (AVE, Brainwave Entrainment)
Audio-visual entrainment (AVE) is a therapeutic technique that uses rhythmic light and sound stimuli to influence brainwave activity, guiding the brain toward specific frequency states associated with…
Autistic Meltdown (Meltdown, Sensory Meltdown)
An autistic meltdown is an intense, involuntary response to overwhelming sensory, emotional, or cognitive overload, during which an autistic person may temporarily lose the ability to regulate their b…

Decreased Sound Tolerance (DST, Sound Intolerance)
Decreased sound tolerance (DST) is an umbrella term for conditions in which everyday sounds are perceived as uncomfortably loud, threatening, or emotionally distressing. It encompasses hyperacusis (ab…
Intentional Sensory Stimulation
A design approach for technology that deliberately leverages optimal sensory modes — visual, auditory, haptic, or multimodal — to facilitate comprehension and engagement, rather than simply reducing i…
Interoception (Interoceptive Awareness)
The sense of the internal state of the body, including perception of heartbeat, breathing, hunger, thirst, temperature, pain, and emotional feelings. Interoception enables people to recognize and resp…

Sensory Based Motor Disorder (SBMD)
A subtype of Sensory Processing Disorder in which the brain has difficulty using sensory information to plan and execute motor actions. SBMD encompasses two sub-types: postural disorder, which affects…
Sensory Processing (Sensory Integration, Sensory Processing Differences)
Sensory processing refers to the way the nervous system receives, organizes, and responds to sensory input from the environment, including sound, light, touch, smell, taste, and movement. When sensory…
Sensory Processing Disorder (SPD, Sensory Integration Disorder, Sensory Integration Dysfunction)
A condition in which the brain has difficulty receiving, organizing, and responding to sensory information from the environment and the body. People with Sensory Processing Disorder may be oversensiti…
Sound Localization (Auditory Localization)
The ability to determine the direction and distance of a sound source using auditory cues such as differences in timing and intensity between the two ears. Blind and visually impaired people often dev…
Tactile Reading (Touch Reading)
The process of reading text through the sense of touch, primarily using the fingertips to perceive raised characters such as braille. Tactile reading requires distinct perceptual and cognitive skills …
