With the advent of the information society in recent years, creativity is becoming increasingly important, and divergent thinking is gaining prominence. The Alternative Uses Test (AUT) is the most commonly used test using language for evaluating divergent thinking. However, its result is affected by differences in native language and the evaluation is dependent on the person conducting the assessment. The purpose of this study is to propose a new task to evaluate the flexibility of divergent thinking that solves the problems of the AUT．
In the task, a user is required to generate a color queue and flexibility is evaluated by how many varieties of color sequences are in a color queue consisting of color sequences, which is called Color Queue Creation Task (CQCT). Based on the relationship between randomness a person possesses and divergent thinking from previous research, we considered that the more random color sequences in a color queue, the more flexible it is. In CQCT, a user selects colors while satisfying the requirement of generating a more random color queue.
The experiment to validate CQCT was conducted with the participation of six university students. We asked them to perform the CQCT under three conditions: presenting color dot background, gray-scale dot background, and non-presenting. In addition to this, we asked them to perform AUT to examine the relationship between CQCT and existing divergent thinking tests. As a result, while no correlation between flexibility in CQCT and flexibility in AUT was shown, flexibility under the presenting condition was higher than under the non-presenting condition. This suggests that CQCT can be useful as a divergent thinking test if similar results are obtained with a larger number of participants.
