In creativity research, creative thinking such as fixation that negatively affects to the flexibility of idea generation are known. Currently, the detection and elimination of these negative factors highly depends on human skills and techniques. In this paper, we report a hypothesis verification aimed at detecting negative factors using gaze information. Specifically, we conducted hypothesis verification experiments on whether or not the length of gaze fixation time to the existing idea lowers the flexibility of idea generation in divergent thinking task. As a result of the experiment, there was no significant relation between the length of gaze fixation time to existing idea and flexibility of idea generation. As another characteristic result, a cubic regression was observed between blink rate and flexibility, which was similar to the previous study.
