Answer: extinction is occurring.
Explanation:
In this example, what happens is extinction, meaning that the reinforcement provided for problem behavior (engaging in a discussion about the importance of not interrupting people when they speak) is discontinued to reduce or eliminate the problem behavior. As Jim´s interruptions are ignored, he doesn´t get the attention he wants and stops interrupting.
The other options are incorrect because this is not an example of shaping (a behavior is changed by rewarding the successive approximations to the desired behavior), discrimination (the ability to differentiate two distinct stimuli), nor generalization (the inclination to react in the same way to similar stimuli).
