A patient with cocaine use disorder receives lottery-based reinforcement where the chance of winning a prize increases with consecutive cocaine negative urines, but resets to baseline upon a positive urine. This specific schedule of reinforcement in contingency management is known as:

• A Fixed ratio schedule
• B Escalating with reset schedule ✓
• C Variable ratio schedule
• D Continuous reinforcement schedule

Explanation

The escalating with reset schedule is a specific contingency management design where the value or probability of reinforcement increases with consecutive abstinent samples, but resets to baseline upon a positive sample or missed appointment. Fixed ratio provides reinforcement after a set number of responses. Variable ratio provides reinforcement after an unpredictable number. Continuous reinforcement rewards every instance of the target behavior.
