For this purpose, 40 soccer players in Iran first division league with mean age of 28.65±3.9 years in different positions participated in this study. To measure impulsiveness features, Barratt Impulsiveness Scale (BIS-11) and Continuous Performance Test (CPT) were used. Multivariate analysis of variance results indicated that goalkeepers and defenders achieved higher scores in cognitive and motor variables of impulsiveness factors and in misdiagnosis of continuous performance test items than the middle players and offenders (<em>F</em>_(9,82)=3.126, <em>P</em>=0.001, Wilks Lambda 0.228, partial <em>η²</em>=0.389). Based on these results, it can be stated that impulsiveness is one of the main explanatory factors of players' tendency towards different soccer positions along with other relevant variables.   The aim of this study was to investigate impulsiveness features of soccer players in different positions according to the mastery orientation approach.
