Professor Hiroshi Miyawaki and Professor Shu Morioka, Ph.D. course students at Kio University Graduate School, and Professor Shu Morioka, have a relationship between sensorimotor cues and cognitive cues when self-other attribution during motor control is achieved. It was clarified whether it is used in.
So far, Mr. Miyawaki and Professor Morioka have been collaborating with Nijukai Ishikawa Hospital to study the misattribution of sensory feedback and its improvement in stroke patients with sensorimotor disorders.Attribution to oneself and others at the time of motor control is to distinguish whether oneself controls one's own movement or not.It is thought that sensorimotor cues such as internal prediction and sensory feedback and cognitive cues such as knowledge and thinking are involved in self-other attribution, but the relationship between these clues in determining self-other attribution. Regarding sex, it was not well understood whether cognitive cues that were not directly involved in exercise could affect self-other attribution during motor control.
Therefore, in this study, we conducted an experiment to verify the effect of cognitive cues on self-other attribution by having participants (healthy college students) perform feedback control tasks while manipulating the amount of information on sensorimotor cues.As a result, cognitive cues were not used for self-other attribution in situations where sensorimotor cues were fully available, but cognitive cues were also used for self-other attribution in situations where the amount of sensorimotor cues was small. I understand.Interestingly, on the other hand, no cognitive cues were effective in situations where few sensorimotor cues were available.
From this study, it was shown that self-other attribution during motor control is based on sensorimotor cues, but cognitive cues can be compensated for in situations where the amount of information available for sensorimotor cues is small.However, it was also suggested that the use of cognitive cues is limited to specific situations that depend on the amount of information available for sensorimotor cues.
This discovery can be said to be a self-other attribution strategy during motor control in healthy subjects, but in the future, we will verify the self-other attribution strategy even in patients with sequelae of stroke that may cause problems in the use of sensorimotor cues. He says he plans to go.
