• Dunn’s Model of Sensory Processing – A framework positing four sensory processing patterns: Low Registration, Sensory Seeking, Sensory Sensitivity, and Sensory Avoidance, based on thresholds for sensory input and self-regulation strategies.

  • Low Sensory Registration – High threshold and passive response; individuals may not notice sensory stimuli.

  • Sensory Sensitivity – Low threshold and passive response; individuals experience discomfort or distress from sensory input.

  • Sensory Avoidance – Low threshold and active response; individuals attempt to avoid or minimize sensory input.

  • Sensory Seeking – High threshold and active response; individuals actively pursue sensory stimulation.
