Answer:
Prejudgment.
Explanation:
As the exercise presents, Dolores' ability to listen is being hindered, limited, by prejudgment. This, as it's name suggests, is to have an opinion about a situation (in this case an interview with the President of the United States) before knowing or considering all the facts. She says she "already knows" what he has to say but she may not even know what subject he is adressing. Perhaps he was about to speak about something completely new and important but she let her prejudgment get the better of her.
