This study is one of the first to employ an online interactive creativity task platform to explore one's creativity performance in a paired-player mode. It analyzed the differences between 342 participants' performances in single- and paired-player modes on two creativity tests: The Alternative Uses Task (AUT) and Chinese Radical Remote Associates Test (CRRAT). Potential factors affecting performance in the paired-player mode were summarized based on participants' responses to the AUT and CRRAT to analyze the correlation between the factors and creativity performance. Results showed that playing the AUT or CRRAT, low scorers can improve fluency, flexibility, originality, and performance by referring to response category or another participant's answer, closing the gap between their score and that of the high scorers. These results reveal both the similarities and differences of creativity performance on the two tests in an interactive situation and the correlation between response strategies and creativity performance in the paired-player mode. This study utilized online standardized measurement tools to explore how two persons cooperate in creativity tests to reveal that creativity performance may vary between tasks.
