摘要：background An important component of mental training in sport is the utilization of positive imagery.The “human brain cannot distinguish between an imagined experience and a real experience.The same areas of the brain light up in an imagined experience or imagined performance as in a real experi_ence or performance.For that reason,positive performance imagery has enormous potential” (Orlick,2008,p.101).Im?agery “has been described as a centre pillar of applied sport psychology” research (Morris,Spittle,& Perry,2004,p.344).The aim of the present study was to examine reliability and validity characteristics of the Polish language version of the Sport Imagery Ability Measure (SIAM).participants and procedure Polish athletes (N = 316) from a range of sports and competitive levels completed the 48 item SIAM.The partici?pants (163 male,153 female) were aged between 12 and 57 years (M = 22.15,SD = 8.25).results Results indicated that the SIAM had sound internal consis?tency and maintained good stability over a 3-week period.Confirmatory factor analysis demonstrated that the a priori 3-factor structure of the SIAM resulted in a set of accept_able and poor fit indices (CFI =.91,NFI =.90,RMSEA =.12).Finally,differences in athletes’ imagery abilities were exam?ined in relation to competitive level,gender,and age.conclusions Overall,results generally supported the reliability and con?struct validity of the Polish version of the SIAM.
