Relations between Preschool Children's Fine Motor Skills and General Cognitive Abilities

An increasing number of findings suggest that cognition is grounded in sensorimotor experiences. Research suggests that fine motor skills (FMS) link to cognitive abilities. Existing studies, however, lack conceptual and methodological differentiation regarding FMS and little is known about the directional nature of links. In study 1, we measured three types of FMS, namely dexterity, grapho-motor skill, speed-dominated FMS in a sample of preschool children (n = 78) aged 4.42 years, and analyzed their links with nonverbal reasoning and general knowledge. Factor analyses verified the existence of these three distinct subsets of FMS. A unique link was found for dexterity and reasoning after controlling for age, attention and processing speed. In study 2, using a cross-lagged-panel design with two measurement points one year apart in preschool (n = 84), a cross-lagged link from four-year-old children's dexterity to their reasoning skills at age five was demonstrated. Findings support the idea of FMS being involved in the development of cognitive abilities.
