The feeling and judgment that "it was the one who caused the behavior" is called the sense of exercise subject, and it is thought that the sense of exercise subject is composed of two levels.
The first level (comparator model) is based on sensorimotor function, and when one's movement and the result match in time, one feels a sense of motor subjectivity.At the second level, a sense of motor subjectivity is formed based on cognitive cues such as expectations, beliefs, and context.

 Especially for the first level, it is known that the time error between the exercise and the result reduces the sense of exercise subject, and there is a time window of how much time error the sense of exercise subject can be.This time, a team from the Neurorehabilitation Research Center of Kio University investigated whether the time window of exercise-oriented feeling is different between children and adults.

 The experiment involved 6 school-aged children aged 12-128 and 21 young adults aged 23-30.In a program where ■ jumps on the screen when a participant presses a button, answer "whether you feel like you jumped ■" while inserting various time delays between the button press and the jump. By having them do it, we quantified the time window of the feeling of exercise.

 As a result, it was found that the greater the time error, the smaller the sense of exercise subjectivity in both school-aged children and young adults, but the time window of the sense of exercise subjectivity in school-aged children was significantly shorter than that of young adults.It may suggest that children have a more fixed connection between the subject and the environment and are less adaptable and flexible.

 Furthermore, when a manual dexterity test was conducted, a correlation was found between the time window of exercise-oriented feeling and the manual dexterity only for school-aged children.This suggests that the first level of the two levels of motor subjectivity contributes relatively significantly to the formation of motor subjectivity in children.Since it is difficult for children with developmental coordination disorder to learn motors based on the comparator model, it can be said that this suggests that some problems may have occurred in the sense of motor subjectivity.
