Final answer:
Conformity is the extent to which an individual complies with group norms or expectations. The student's description of Ethan changing his behavior to align with the group's behavior illustrates the concept of conformity.
Step-by-step explanation:
Ethan's behavior, conforming to the group's actions, exemplifies the psychological phenomenon known as conformity. Conformity is the tendency to adjust one's behavior, attitudes, or beliefs to align with the prevailing norms or social expectations within a group.
In this scenario, Ethan changed his actions to be consistent with the group's behavior, showcasing the influence of social pressure on individual decision-making. Conformity can stem from a desire for social acceptance, a fear of rejection, or a belief that the group possesses more accurate information.
This adaptive behavior is a fundamental aspect of social psychology, highlighting how individuals often seek to fit in with the collective actions of their social environment.
