The main purpose of this study was to examine the effect of metamotivational states on self-efficacy perceptions and motor performance in dart throwing beginners in easy and difficult conditions. For this purpose, the paratelic dominance questionnaire (Cook & Gerkovich, 1993) was distributed among 140 male students, and 32 participants were randomly divided into two groups (16 in a telic group and 16 in a paratelic group). Each task consisted of three blocks of eight trials, and each trail consisted of 4 throws. Participants completed the Self-Efficacy Scale (Feltz & Chase, 1998) in their pretest and after trials 8, 16, 24. Data were analyzed with repeated measure, ANCOVA test and LSD post hoc test. The results showed a significant difference between paratelic and telic participants in self-efficacy perception (difficult task), and no significant difference in motor performance. Overall, the study only partially confirmed the reversal theory.
