In this study, we evaluated the effects of a cognitive response task using smiling facial expression stimuli on physical and cognitive abilities, training mood, and motivation during multitask training that combines cognitive response tasks and walking using a Walk training robot. The results showed that the cognitive ability test on working memory and the evaluation index of positive emotion were significantly higher in the facial expression response task group than in the signal response task group.
