Abstract
The purpose of this study was the comparison of the required time and repetition for the acquisition of simple and complex timed motor sequenced task (TMST) among various practical conditions and determination of suitable practical methods with respect to individual characteristics. One hundred and fourteen university students, with the age range of 19-25 years old, were divided in 4 groups  according to Raven Intelligence test, Achievement Motivation Test, Reaction time and Purdue pegboard, and based on the first, second and third quadrants. Then they were randomly placed in one of the two groups of simple and complex TMST and also in one of the practical conditions of the interaction of the organization of practice (random, blocked, constant), and practical distribution (massed, distributed). The subjects trained 6 days under their specific practical condition of simple or complex TMST, in a way they reached to the acquisition criterion (accuracy %75, timing %25, stability %15) in a practical training block. The number of repetitions and passage of time before this criterion block were considered as the minimum required time and repetition for acquisition of TMST. The data were analyzed using two-factor analysis of variance, independent t-test and Xi - 2 test (=&alpha0.1). The results showed individuals with different characteristics have acquired simple TMST in blocked and  massed condition (except group ) in average within 30 repetitions and 1347 minutes, and complex TMST in random and distributed condition (except group ) in 25 repetitions and 1228 minutes. In addition, the findings showed that the principles of practical programming is affected by both the complexity level of task and individual characteristics. At last, it seems there is a need of more studies on the combination effect of the environment, individual and task on the acquisition fine motor skills.
