Which term is defined as a reward marker that bridges the stimulus and the conditioned reinforcer/secondary reinforcer?

• A. Clicker
• B. Reinforcer
• C. Spontaneous Recovery
• D. Extinction

Answer: (A)

A reward marker that clearly signals the exact moment a behavior occurs and links it to the reward is the clicker. In clicker training, the click marks the precise moment the dog performs the desired behavior, creating a clear bridge between the action and the reinforcement that follows. This immediate, distinctive signal helps the animal understand which behavior earned the reward, even if there’s a short delay before the primary reinforcement arrives. With repeated pairing with food or another primary reward, the clicker also becomes a conditioned reinforcer, but its defining role here is to bridge the stimulus (the behavior) and the reinforcement.

A reinforcer is the actual reward that increases the likelihood of the behavior, not the signaling bridge. Spontaneous recovery and extinction describe changes in behavior after reinforcement is removed or after a rest period, rather than a signaling tool used to connect behavior to reward.
