When the second group of children came in, they were brought to the same room, shown the same anagrams, but this time Miss Smith told them which anagrams to do and which markers to write their answers with.

Now when the third group came in, they were told that their anagrams and their markers had been chosen by their mothers.

The kids got to choose which pile of anagrams they would like to do, and they even got to choose which marker they would write their answers with.

Anglo Americans, they did two and a half times more anagrams when they got to choose them, as compared to when it was chosen for them by Miss Smith or their mothers.
