In this study we tested the hypothesis about advantage of academic motivation profile with dominating intrinsic motivation over another profile with equally high intrinsic, self-esteem and controlled types of motivation (and low level of amotivation). Latent class analysis confirmed the suggestion that these two profiles are most typical in university students. Students with high and dominating intrinsic motivation showed highest curiosity, consistency of interests, perceived academic control and academic achievements but didn’t differ from students with high controlled motivation by the perseverance of effort that was high in both types. Generally the results show that high extrinsic controlled motivation is a disadvantageous factor that decreases student motivational potential. The results are discussed from the point of view of self-determination theory and need model of motivation.
