Explanation:
The concept of social facilitation was first proposed by Norman Triplett. After observing a cycling event, in which he noticed that cyclist performed better when they have others around competing with them, rather than cycling alone just against time.

He observed that, children wound the fishing reel faster in the presence of other children performing similar task, when compared to when perform such task alone.
