In addition, in "empathy and support skills", coaches who were not both winning and process oriented showed significantly lower scores than coaches who were process oriented.
• The relationship between competitive level and visuospatial working memory - A study of competitive cyclists
  Joint Author, Sep. 2015, The 61st Annual Meeting of the Japanese Society of Hypnosis and Medicine, Nippon Sport Science University, This study examined overall imagery, clarity, and control in cycling athletes, who have a strong element of closed skills, and clarified the relationship with competitive ability. The participants in the experiment were 19 men and 4 women. As a result, no difference was found between the ability to clearly visualize the image and competitive level. Therefore, it was shown that it is necessary to improve visuospatial working memory in order to improve competitive ability and demonstrate one's true potential. In addition, because female athletes were significantly better able to visualize the entire image than male athletes, it was suggested that efforts should be considered that take gender differences into account.

Path analysis showed that threat perception and inference errors increase depressive symptoms through competitive anxiety, and that inference errors directly increase depressive symptoms. Furthermore, it was shown that cognitive control may reduce depressive states directly or through competitive anxiety.

• Consideration from the perspective of meaning to improve athletes' logical thinking errors
  Sole Author, Oct. 2023, The 50th Annual Meeting of the Japanese Society of Sport Psychology, This study exploratory examined the effect of assimilation and accommodation of meaning aimed at reducing inference errors on depressive symptoms. The survey subjects were 1,317 people affiliated with a sports university, of which 980 who answered that they were continuing to play were analyzed. The results showed that while inference errors in athletes have a high impact on depressive symptoms, it is possible that depressive symptoms can be reduced through accommodation of meaning. However, accommodation can be dangerous as it can lead to negative understanding and interpretation due to newly obtained information in the process of trying to modify one's own perspective and way of thinking, so it is thought that when providing assistance or intervention, it is necessary to work towards a positive direction.
