Which processing pattern is NOT a part of Dunn's four processing patterns?

• A. Visual tracking
• B. Sensory seeking
• C. Sensory avoiding
• D. Low registration

Answer: (A)

Dunn's four processing patterns describe how a person responds to sensory input based on their sensory thresholds (high vs low) and whether they regulate that input actively or passively. The four patterns are sensory seeking (high threshold with active self-regulation), sensory avoiding (low threshold with active self-regulation), sensory sensitivity (low threshold with passive self-regulation), and low registration (high threshold with passive self-regulation). Visual tracking is not a processing pattern in this framework; it’s a specific visual motor skill—an eye movement task—rather than a descriptor of how someone consistently processes and responds to sensory information. The other options fit as examples of the Dunn patterns: sensory seeking involves actively getting more input, sensory avoiding involves actively reducing input, and low registration describes a passive tendency to miss stimuli despite plenty of input. So visual tracking is the one not part of Dunn's four processing patterns.
