Which term describes a cue signaling reinforcement is available for a specific response?

• A. Discriminative Stimulus
• B. Extinction cue
• C. Discrimination training
• D. Punishment cue

Answer: (A)

A discriminative stimulus functions as a cue that signals reinforcement is available for a specific response. In operant conditioning, when this cue is present, reinforcement is contingent on performing the target behavior, so the likelihood of that behavior occurring increases. The cue essentially sets the occasion for the behavior to occur. When the cue is absent, reinforcement isn’t available for that behavior, so it’s less likely to be emitted. This distinguishes it from an extinction cue, which would indicate reinforcement is not available; discrimination training, while related, is the process of teaching organisms to respond to different cues appropriately; and a punishment cue would signal the availability of a punishment rather than reinforcement.
