Blaine works in a factory producing car stereos. He notices that workers produce more stereos by the end of the day when they work together in the same room than when they work in separate rooms. His observation is consistent with a classic study conducted by which of the following researchers?

a. Lewin

b. Asch

c. Triplett

d. Sherif

The answer is c. Triplett.

Explanation:

Accodring to Norman Triplett, people tend to perform better in the presence of others. This is also known as the social facilitation effect.

Triplett had noticed that cyclists had faster times in the presence of other cyclists. He reproduced the experiment with children performing simple lab taks and the results were consistent with his observations (the children did better when in the same room than when in separate rooms).

Triplett is the correct answer.

Explanation:

Norman Triplett was an American psychologist born in Perry, Illinois. His experiment, social facilitation effect, is considered as the first one in sports psychology. There, Triplett noticed that cyclists were faster when they faced each other instead of just running alone. He did a similar experiment with children, by setting some tasks in a laboratory. First, he made them work alone and then in pairs. In both experiments, people performed better when they were surrounded by others than when they were by themselves.
