Take Note: Doodling Can Help Memory

For the experiment, a two-and-a-half minute listing of several people's names and places was played for test subjects, who were charged with writing down only the names of the people said to be attending a party. During the recording, half the participants were asked to simultaneously shade in shapes on a piece of paperwithout attention to neatness. Participants were not told they were taking part in a memory test.

When the recording ended, all were asked for the eight names of those attending the party as well as eight place names mentioned in the audio. Those asked to doodle wrote down, on average, 7.5 names and places, while those who didn't doodle listed only 5.8.

问题是，这两组人的差异没有被排除掉。试验中，除了doodle这一项差异外，还有其他差异。而且样本也小。
