Which outcome is most associated with positive reinforcement in training?

• A. Increased likelihood of the target behavior when followed by a reward.
• B. Immediate cessation of a behavior due to punishment.
• C. Reduction of a desirable behavior through withdrawal of rewards.
• D. Unchanged behavior due to lack of feedback.

Answer: (A)

Positive reinforcement strengthens a behavior by delivering a reward after the behavior, so the dog is more likely to repeat it. When the dog sits and a treat is given right away, the sit becomes more likely in the future because the reward creates a positive association with that action. This immediate, desirable consequence is what teaches the dog to perform the behavior again.

The other descriptions describe different outcomes not produced by positive reinforcement: punishment aims to suppress behavior by adding something unpleasant; removing rewards can reduce or extinguish a behavior; and no feedback leaves the dog without a learning signal, so behavior doesn’t reliably change.
