Which reinforcement strategy is a variation of differential reinforcement focusing on speed of response?

• A. Differential reinforcement
• B. Fixed Interval
• C. Variable Interval
• D. Limited Hold Reinforcement

Answer: (D)

Focusing on how quickly a response occurs after the opportunity to earn reinforcement is presented is the idea behind a limited hold. This variation of reinforcement tightens the time window in which reinforcement is available after the target behavior. Because the reward must be obtained within that brief hold period, the learner is encouraged to respond promptly rather than delaying.

In contrast, interval schedules (both fixed and variable) govern when reinforcement is available based on elapsed time, not on how fast the response occurs after that opportunity. Differential reinforcement, in general, reinforces a specific behavior while withholding reinforcement for others, but when the emphasis is on speeding up the response, the limited hold adjustment is what adds that speed requirement.
