Which concept focuses on generalization of cues across environments through training variations?

• A. Differential Reinforcement
• B. Fixed Schedules
• C. Proofing
• D. Variable Schedules

Answer: (C)

Proofing focuses on making a trained cue reliable across different places and situations by introducing training variations. By practicing the cue in a variety of environments—different rooms, outdoors, with different people, at different times of day, and with mild distractions—you reinforce the response under many conditions. This builds the dog’s ability to generalize the behavior beyond the exact training context to real-world settings. The other concepts deal with how often or when rewards are given (reinforcement schedules) or with reinforcing a different behavior, rather than expanding the cue’s effectiveness across environments.
