Before
We will ask participants to do a two-stage task. At each stage, participants will be given a list of 18 Chinese poetry and asked to remember them. They will be informed of there will be a quiz to test their poetry memory.
We will randomly divide participants in three groups. For the participants in the control group, no feedback will be provided. For the participants in the class-rank treatment group, they will be informed of their rank in their classroom. We can interpret the class rank as a measurement of one's relative position in a large comparison group. For the participants in the group-rank treatment group, they will be informed of their rank in a group including those who sit in the same column as them. In this case, participants will learn their relative position in a small comparison group. Then, they will be given another poetry list and test.
