Final answer:
In terms of operant conditioning, the traffic lights serve as discriminative stimuli.
Step-by-step explanation:
In terms of operant conditioning, the traffic lights serve as discriminative stimuli.
Discriminative stimuli are cues or signals that indicate when a particular behavior is likely to be reinforced. In the case of traffic lights, the red light signals to a driver that it is not the appropriate time to drive, while the green light signals that it is safe to proceed.
Therefore, the traffic lights in this scenario act as discriminative stimuli, providing information to the driver about the appropriate behavior to engage in based on the current situation.
