These include explicit process in which the performer consciously knows the acquisition of the skill and the other one is an implicit process in which the performer has no conscious knowledge of acquiring the skill. The purpose of this study was to investigate the effect of explicit and implicit instructions and sleep on  the  performance of the fine motor skill. Participants in this study included 30 right-handed volunteer students with a good sleep quality, aged between 18-25 years old. They were randomly divided into two homogeneous explicit (N = 15) and implicit (N = 15) groups based on Purdue Fine Motor Skill Test and Simple Reaction Time. Each group participated in a three-time round at six in the afternoon, 12 midday on the same day, and at eight o'clock next morning in a Timed Motor Sequences Task. The data was analyzed by ANOVA with repeated measures. The results showed that in the accuracy of the short elements, stabilization was done but promotion was not observed but there was no change in the accuracy of the long elements and there was no significant difference between groups. https://www.biotech-asia.org/vol15no3/the-effect-of-explicit-and-implicit-instructions-and-sleep-on-consolidation-of-the-accuracy-of-elements-of-a-fine-motor-skill/ Accuracy; Explicit and Implicit Learning Instructions; Fine Motor Skill; Nighttime Sleep
