Which conceptual distinction is most relevant to understanding social facilitation?

A) task vs.socioemotional
B) dominant vs.nondominant
C) internal vs.external
D) unitary vs.discretionary

Social facilitation theory suggests that the presence of others enhances performance on dominant (well-learned or easy) tasks and impairs performance on nondominant (new or difficult) tasks. This distinction is crucial for understanding how and why performance changes in social contexts.
