Abstract
This study aimed to evaluate the developmental progression of young children’s achievement in executive function tasks using a grip strength grading visualization system. The executive function task applied by this system involved comparing left- and right-colored images projected on a display screen to analyze and characterize the coordination of thoughts and actions at the following stages: (1) when the color of the image changes based on grip strength (perception), (2) when grip strength is adjusted (cognition), and (3) when one side has the same color (motion). Specifically, the developmental process of achieving an executive function task was initially investigated in a toddler from 2 years and 6 months to 3 years and 6 months of age, which suggested an increase in achievement over time. Subsequently, developmental change of the success rate of achieving executive function tasks was examined in 4 kindergarten children, indicating an increase in the success rate upon reaching the age of 3 years and 6 months. The findings of this study are expected to contribute to an understanding of social and emotional skills development by employing a grip strength grading that accurately adjusts the amount of force required in interactions with objects, which is essential for preschool skills support.
