  Abstract:
Spatial ability, essential for navigating and interacting with the environment, comprises small-scale (e.g., mental rotation) and large-scale (e.g., spatial navigation) skills. Previous research underscores the influence of motor expertise on these abilities, yet comparative studies among different types of movement experts are limited, especially regarding the impact of gross motor skills on large-scale spatial abilities. This case-control study compared small-scale and large-scale spatial abilities among fine movement experts, gross movement experts, and non-movement experts. Ninety participants (30 per group) were assessed through computer-based spatial ability tests, including the Revised Purdue Spatial Visualization Test (PSVT: R), Mental Rotation Test, a navigation task developed in Unity 3D, and Triangle Completion Test (TCT). Fine movement experts excelled in small-scale spatial tasks compared to non-movement experts. Gross movement experts demonstrated superior large-scale spatial abilities, evidenced by lower errors in TCT and higher navigation scores, distinguishing their performance in spatial navigation and orientation from both fine movement experts and non-movement experts. The study highlights the distinct impacts of fine and gross motor expertise on spatial abilities, with gross motor skills particularly benefiting large-scale spatial navigation. These findings suggest potential clinical applications of gross motor training for improving spatial abilities in neurological populations, advocating for further research in immersive virtual environments and exploring lateral dominance effects on spatial performance.
