Objective: To investigate correlations between motor skills with focused and shifting attention among preschool children, and to provide basis for the overall development of preschool children aged 4-6 years. Methods: During March to June 2020, a total of 165 preschool children aged 4-6 years were selected and investigated with subscales of the Bruininks Oseretsky Test of Motor Proficiency 2nd Edition (BOT-2) for agility and limb bilateral coordination assessment, and subscales of the Movement Assessment Battery for Children test 2nd Edition (MABC-2) for throwing and catching skill assessment, as well as balance subscale for the assessment of limb movement coordination, hand eye coordination, agility, and balance. The Kansas Reflection Impulsivity Scale for Preschoolers for Pre schoolers (KRISP) and Dimensional Change Card Sort (DCCS) were used to assess focused and shifting attention levels. Correlation and linear regression analyses were performed for statistical analysis. Results: Except for one handed throwing skills and shifting attention, there were statistically significant gender differences between boys and girls in total score of body movement coordination, total score of hand to eye coordination, hand to hand connection, total score of agility of movement, total score of movement balance, static support, walking on tiptoe, foot to foot jump and focused attention( t =-6.86, -2.00 ,-3.15,-3.75,-3.00,-2.95,-2.18,-2.11,-3.21, P ＜0.05), and girls were better than boys; children s total score of body movement coordination, total score of hand to eye coordination, hand to hand connection, agility of movement, walking on tiptoe and focused attention improves with age( r =0.47,0.41,0.47,0.51,0.16,0.31, P ＜0.05); After excluding the interference of gender and age, total score of body movement coordination was significantly correlated with preschool children s focused attention( β=0.31,95%CI =0.08-0.39, P ＜0.01). Conclusion Limb movement coordination and focused attention are significantly and positively correlated among preschool children aged 4-6 years. Therefore, preschool education and family activities should focus on designing and developing limb movement coordination related games and courses to enhance the focused attention of and form favorable attention quality in preschool children aged 4-6 years.
