Answer:
The correct answer would be, Social Referencing.
Explanation:
When an infant uses the affective display of an adult towards an environment, object, person, or situation, to regulate his or her own behaviors towards that environment, object person or situation, this process is called as Social Referencing.
For example, as in this question, Abed looked at her mother to take a clue about how to encounter the person who just came into the room and is delighted to see him, his mother's broad smile for Abed's uncle tells Abed that he can move towards that person, as his mother is given a positive sign which he took as a reference. So Abed demonstrated the Social Referencing.
