2.6.2. Remote Association Task (RAT)
An adapted Chinese version of the Remote Association Task (RAT) was implemented to assess convergent thinking (Duan et al., 2020). During the task, participants were presented with three Chinese characters and were asked to generate a Chinese character that could combine with each of the shown three characters to produce a reasonable word. For example, one of the RAT questions was: “board, hole, color”, and the answer is: “black” which can be combined into “blackboard, black hole, and black color”. Each question was randomly presented for a maximum of 20 s. Once the participant figured out the answer, he or she could immediately press the keyboard (space key) to report it. The pre-test and post-test contained 20 different item groups with solution rates ranging from 40% to 65%. To prevent interference at the linguistic level, all of the words were chosen from the Modern Chinese Frequency Dictionary (1989). Previous research has found that the revised RAT has adequate internal consistency.
