Final answer:
The coach's behavior illustrates the barrier to social perception known as selective perception.
Step-by-step explanation:
The coach's behavior in ignoring the complaint of the football team about their quarterback, Jorah, because Jorah was the most valuable player, illustrates the barrier to social perception known as selective perception. Selective perception refers to when we selectively choose which information to pay attention to and process, based on our own biases or preconceived notions. In this case, the coach is selectively perceiving Jorah's rude behavior because of his value to the team.
