What is an example of a naturally occurring discriminative stimulus in action?

A naturally occurring discriminative stimulus is an environmental cue that signals the availability of reinforcement or specific responses in a given context. In this case, the correct answer illustrates a scenario where a person sees a stop sign and comes to a stop. The stop sign acts as a discriminative stimulus that signals the driver to stop, as compliance with this signal often results in safety and avoids potential negative consequences (like accidents or getting pulled over by law enforcement).

This response indicates that the individual recognizes the stop sign and acts upon it appropriately, demonstrating an understanding of the traffic rule associated with the sign. The stop sign is a clear and real-world example of a discriminative stimulus, as it is meant to evoke a specific behavior in the context of driving.

The other options do not exemplify the concept of a naturally occurring discriminative stimulus in action in the same way. Ignoring a stop sign, for instance, does not involve a response to the stimulus; instead, it reflects a lack of action. Explaining what a stop sign means does not involve the individual's behavior in response to the sign in a real-world context. Similarly, drawing a picture of a stop sign is unrelated to the actual situation of driving and does not represent a response to the stimulus in action.
