Which schedule provides reinforcement for the first correct response after a variable amount of time, regardless of the number of responses?

• A. VARIABLE INTERVAL
• B. VARIABLE TIME SCHEDULE
• C. VARIABLE RATIO
• D. FIXED INTERVAL

Answer: (B)

This item focuses on how reinforcement is scheduled based on time rather than the number of responses. A variable time schedule delivers reinforcement after changing time intervals, and it does not depend on how many responses the learner emits. The key idea is that reinforcement opportunities come from the passage of time—after an unpredictable amount of time has elapsed, the next correct response can be reinforced, regardless of how many responses occurred in the interim. This distinguishes it from schedules controlled by response count or by a fixed time, where the patterns of reinforcement would look different.
