Which option best captures learned irrelevance?

• A. A pre-exposure effect in which the dog learns to ignore stimuli that have no meaning.
• B. An immediate, uniform response to familiar cues.
• C. A weariness that reduces responsiveness to all stimuli.
• D. A learned fear response to cues.

Answer: (B)

Learned irrelevance occurs when a dog learns that certain cues do not predict anything useful, so attention to those cues fades and later conditioning to them is harder. The option describing a pre-exposure effect in which the dog learns to ignore stimuli that have no meaning best fits this idea. By encountering nonpredictive cues without consequences, the dog assigns them low significance and stops paying attention, which makes future learning about those cues less likely. This is related to latent inhibition, where prior exposure to irrelevant cues slows down or prevents conditioning to them. The other options point to different processes: an immediate, uniform response to familiar cues suggests a general, non-specific reaction rather than selective ignoring; weariness reducing responsiveness to all stimuli signals fatigue or low arousal, not a selective irrelevance; a learned fear response to cues is conditioning that increases responsiveness, not ignores them.
