Fluency is described as the second phase of learning and focuses on

• A. Initial acquisition of a new skill
• B. Speed and accuracy of the response
• C. Extinction of a behavior
• D. Generalization to new contexts

Answer: (B)

Fluency in learning emphasizes performing a behavior quickly and accurately once it has been learned. In the second phase, the goal is to increase both the speed of the response and the reliability of its correctness, so the dog can perform the skill smoothly under typical conditions with minimal prompting. This combination—fast performance that remains accurate—demonstrates robust mastery and dependable execution, which is what fluency seeks to establish after the initial acquisition. The other ideas refer to different aspects of behavior change: acquiring a skill is the initial stage where the correct response begins to appear, extinction involves reducing or stopping a behavior, and generalization concerns applying the skill in new contexts or settings. While those are important parts of learning, fluency specifically targets faster, more automatic, and consistently accurate performance.
