摘要：The purpose of the present study was to compare the investment and the decision making of skilled and semi-skilled players in team and individual athletics under stressed conditions. A sample of 60 females from Sanandaj Municipal Basketball and Badminton Clubs consisted of four groups, each with 15 subjects (semi-skilled). To measure decision making, the software was designed to test the speed and accuracy of decision making as a paired decision (2010). To assess "reinvestment", the questionnaire of investment (1992), the review of Jackson and Ashford (2010) and for the success of pressure manipulation under stressed conditions the Cox competitive anxiety state Questionnaire were used (2003). Players responded to game conditions under two situations of high pressure (complex task) and low pressure (simple task). Multivariate analysis of variance was used to compare the groups. The results showed that the level of investment of skilled players was lower than that of semi-skilled players and investment of individual athletes were higher than team ones. Semi-skilled players in individual athletics scored more points in all vigilant scales except in the cognitive deflection variable. In general, investment, skill level and discipline (team-individual) are the most important factors influencing decision-making under pressure.
