1 .<-NARRATOR:-> Listen to part of a lecture in a psychology class.
1 .<-MALE PROFESSOR:-> Now, a study was done that illustrated this phenomenon.
2 .In the study people were given an ordinary task that everyone has probably done before-
3 .they were simply asked to peel potatoes.
4 .And to peel as many potatoes as possible in a given amount of time.
5 .OK, so some people worked alone-
6 .and they were told that the number of potatoes they each peeled would be recorded.
7 .Others peeled potatoes together, as part of a group,
8 .and they were told that only the total number of potatoes peeled would be recorded.
9 .So it would be impossible to tell how any one person had done.
1 .Then researchers compared the results of the people who worked alone
2 .and those that worked together to see if there was any difference.
3 .That is, they took the average score of the people working alone
4 .and compared it to the average score of the people working together in a group.
5 .And they did discover a difference.
6 .It turns out that people working as a group
7 .peeled significantly fewer potatoes than people who worked alone.
