More Direction but Less Freedom? How Task Rules Affect Intrinsic Motivation

Task rules restrict freedom by definition, but do they necessarily harm intrinsic motivation? We examine how task rules for an open-ended writing activity affect intrinsic motivation, or enjoyment, with one's sense of direction and psychological freedom as potential mechanisms. Results from three online experiments (Experiment 1, Experiments 3a and 3b; N = 1,176), conducted with both undergraduate student and adult (Amazon MTurk and Prolific) samples, suggest that task rules may indirectly increase enjoyment by enhancing direction (indirect effect: beta's range [0.09, 0.17], p's < .05), yet at the same time, indirectly decrease enjoyment by reducing freedom (indirect effect: beta's range [-0.31, -0.07], p's < .05). Results from a fourth online experiment (Experiment 2; student sample; N = 121) address a potential alternative explanation, finding that only the task rules, not mere examples, were sufficient to increase direction (rules present: d = 0.55, p = .04; examples: d = 0.25, p = .48) and reduce freedom (rules present: d = 0.78, p < .001; examples: d = 0.22, p = .31). Theoretical and empirical connections are made to self-determination theory and flow theory. Further research is needed to delineate situational and personal factors that may moderate these effects.
