- Para Powerlifting(also: Adaptive Powerlifting, Paralympic Powerlifting)
- A Paralympic strength sport in which athletes with physical disabilities perform bench press lifts. Unlike able-bodied powerlifting which includes squat, bench press, and deadlift, para powerlifting focuses solely on the bench press to accommodate athletes with lower limb…
- Para-Athlete(also: Disabled Athlete, Adaptive Athlete)
- An athlete with a disability who competes in adaptive or Paralympic sports. Para-athletes may have physical disabilities (amputations, spinal cord injuries, cerebral palsy), visual impairments, or intellectual disabilities. They compete using adaptive equipment such as…

- Perceivability(also: Perceivable)
- The quality of information or interface elements being detectable through one or more senses — sight, hearing, or touch. Perceivability is the first principle of WCAG 2.0 and requires that information and user interface components be presentable to users in ways they can…
- Perceptual Guidance
- An instructional technique that directs a user’s attention to specific perceptual features of a target — most commonly color and on-screen location — to help them detect or disambiguate it. In accessibility contexts, perceptual guidance is used in screen-reader cues, tutorial…
- Playback Speed(also: Video Speed, Playback Rate)
- The rate at which video or audio content plays relative to its original recording speed. Most video platforms allow users to adjust playback speed, typically from 0.25x to 2x or higher. For viewers with ADHD, playback speed is an important accessibility feature—faster playback…

- An approach to learning that organises instruction around short, repeatable cycles of attempting a task, receiving feedback, and refining performance, rather than around passive content consumption. Practice-based learning is well suited to embodied skills - sign language, motor…
- Problem-Solving Style(also: Problem-Solving Facets, GenderMag Facets)
- Problem-solving style refers to the characteristic ways individuals approach technology-mediated problem-solving tasks. In inclusive design, particularly in the GenderMag method, problem-solving style is captured across five facets: Motivations (why someone uses technology),…
- Psychoacoustics
- The branch of perceptual psychology that studies how humans subjectively perceive sound - loudness, pitch, timbre, spatial location, foreground/background segregation, and masking. Psychoacoustic principles underpin accessible audio design: screen reader pacing, earcon and…
