Hyperreactivity is

Hyperreactivity is

• A. Decreased intensity
• B. No effect
• C. Variable intensity
• D. Increased intensity

Answer: (D)

Hyperreactivity means an exaggerated response to a given stimulus—the same input produces a stronger, larger reaction than normal. This reflects heightened sensitivity or excitability of the system, so the intensity of the response is increased. Decreased intensity would be hypo-responsiveness, no effect would mean no change, and variable intensity would imply inconsistency; hyperreactivity specifically denotes a consistently heightened response. For example, bronchial hyperreactivity involves the airways constricting more readily to stimuli than normal.
