Answer:
Self-monitoring for cues
Step-by-step explanation:
Self-concept is the idea that a person has about himself. This is a collection of beliefs that explains who we are and how others perceive us. In this case, Sheila is explaining something to her teacher. However, as she does so, she is carefully examining the reactions on her teacher's face. Most likely, Sheila is trying to look for cues in order to better understand herself, and how other people (such as her teacher) perceive her.
