The cooperative game Hanabi is a suitable interactive subject for analyzing cooperative behavior based on implicit intention communication. In recent years, research has been conducted to analyze people's cooperative behavior by comparing the results of cooperating with several Hanabi agents that behave differently. However, these methods have problems such as large costs of experiment with human subjects and the inability to directly observe human's internal psychological states. One solution to these problems is to use models created on cognitive architectures, which are used to reproduce human behavior, and conduct simulations. In this study, we simulated the Hanabi game using model, developed on the cognitive architecture ACT-R, with and without risky actions. As a result, we found that the time spent per game changed similarly to that of the human Hanabi game. It was also suggested that having risky actions as options reduced the learning efficiency to improve scores and increased time required for action. In addition, memory retrieval was found to be a factor that increased the time required for action decisions in Hanabi play.
