When forming academic self-concept (ASC), the question arises of classroom friend achievement or class achievement having a larger effect. One hypothesis suggests that friend average achievement has the larger effect. This is known as the friend dominance hypothesis and is consistent with the local dominance effect model. The local dominance effect model posits that people tend to rely on the most local comparison source when there are multiple comparison sources available. Friends are considered a more local source for comparison than classmates, so this indicates that friends should have a larger effect on ASC than classmates.
