Explanation:
Norman Triplett was an American psychologist during the late 19th century. He is remembered for his experiments related to the social facilitation effect. Triplett began with the observation that cyclists tend to be faster when cycling with someone than when cycling alone. He then conducted a similar experiment that involved 40 children. Triplett discovered that there was a positive relationship between the speed at which the children wound the reel and the presence of other children.
