Habituation is most efficient when the stimulus exposures and training sessions are:

• A. distributed in time
• B. massed in a short period
• C. continuous with no breaks
• D. stepwise increasing intensity

Answer: (A)

Habituation means the animal reduces its response to a repeated, neutral stimulus. It works best when exposures are spread out over time because spacing gives the nervous system opportunities to process each encounter, rest between sessions, and consolidate the quieter response. This leads to a more durable, long-term decrease in responsiveness. Cramming many exposures in a short period tends to produce a quick, temporary drop in response that can rebound later and may involve fatigue or heightened arousal, making the effect less stable. Continuous exposure with no breaks doesn’t allow this consolidation to occur, and stepwise increasing intensity helps with gradual tolerance but still isn’t as effective for durable habituation as distributing exposures over time.
