What are the two types of sensory processing disorders?

• A. Hyperactivity and hypoactivity
• B. Over-responsivity and under-responsivity
• C. Visual and auditory
• D. Proprioceptive and vestibular

Answer: (B)

How a person responds to sensory input is the focus here. Sensory processing disorders are commonly described by the pattern of response to sensations: some individuals are over-responsive, reacting strongly to ordinary stimuli (hypersensitivity), while others are under-responsive, showing a diminished or delayed reaction to sensory input (hyposensitivity). This framing—over-responsivity and under-responsivity—best captures the two types described. The other options mix up ideas like activity levels or specific senses, which aren’t the two broad processing patterns themselves, though the senses can be involved in SPD.
