Desensitization training progression involves exposure to which stimuli?

• A. Textures, weights, and vibration.
• B. Colors, sounds, and smells.
• C. Heights, speeds, and distances.
• D. Static pressure only.

Answer: (C)

Desensitization training progression is about gradually exposing a person to escalating levels of threat or challenge to lessen fear and avoidance. By starting with less daunting situations and moving to more demanding ones, the nervous system learns to tolerate the trigger without an excessive anxiety response. In this context, exposure to heights, speeds, and distances provides progressively more demanding environmental and motor challenges, allowing the person to build coping skills and confidence as each level is mastered. The other options describe tactile or multisensory stimuli used for sensory discrimination or reactivity, not the stepped exposure to fear-provoking contexts that desensitization aims to develop.
