Social facilitation theories refer to explanations for how the presence of others can impact an individual's performance on a task. These theories explore the effects of social influence, arousal, and evaluation apprehension on an individual's performance.
Social facilitation theories explore how the presence of others affects an individual's performance. Two key perspectives are the arousal perspective, suggesting that others' presence increases physiological arousal, and the evaluation apprehension theory, which posits that performance is affected by concern for social evaluation.
Robert Zajonc's 1965 research is foundational, indicating that the presence of others enhances performance on simple tasks but hinders it on complex tasks. Later studies refined this finding, showing the role of perceived evaluation and task familiarity in social facilitation effects.
