In class you sit up front and act as if you are really listening by maintaining eye contact and nodding in agreement with your instructor; however, your mind is far away and not focused on the lecture. You are demonstrating
pseudo-listening.

You've already given the answer -- pseudo-listening -- so I'll just explain what it is.

Explanation:

Pseudo-listening refers to someone acting as if they are paying attention to what someone else is saying when, in reality, they are not. The other person believes you are listening because you act as if you are interested by maintaining eye-contact and nodding at intervals. The Greek root for pseudo means "not real" or "not genuine". Pseudo-listening is, in short, the action of pretending to listen to someone.
