During discrimination training for the color red, the RBT reinforces the learner for touching the red card when asked 'red' and provides no reinforcement when the learner touches the blue card. The blue card in this arrangement is the:
- AEstablishing operation
- BSD
- CS-delta
- DConditioned reinforcer
Show answer and rationale
Correct: C. The stimulus in whose presence a response is not reinforced is the S-delta. The red card (in the presence of the instruction) is the SD because responding to it is reinforced.
- B — The SD signals that reinforcement is available for the response.
- D — A conditioned reinforcer is a consequence, not an antecedent stimulus.
- A — An establishing operation changes the value of a reinforcer; the card does not.
