... Given the importance placed on one's need for autonomy in supporting intrinsic motivation, self-determination theory holds that having choice should result in enhanced intrinsic motivation, as well as other positive motivational and performance outcomes supported by intrinsic motivation (Deci, 1980;Deci & Ryan, 1985;Ryan & Deci, 2000). Much research has supported this postulate of self-determination theory, demonstrating that choice leads to enhanced intrinsic motivation (e.g., Cordova & Lepper, 1996;Iyengar & Lepper, 1999;Patall, Cooper, & Robinson, 2008;Swann & Pittman, 1977;Zuckerman, Porac, Lathin, Smith, & Deci, 1978), as well as enhanced eff ort, task performance, subsequent learning, perceived competence, preference for challenge, and creativity (e.g., Amabile, 1979Amabile, , 1983Amabile, Hennessey, & Grossman, 1986;Becker, 1997;Cordova & Lepper, 1996;Iyengar & Lepper, 1999;Kernan, Heimann, & Hanges, 1991;Patall, Cooper, & Robinson, 2008). For example, in one seminal study on the eff ect of choice on intrinsic motivation, Zuckerman, Porac, Lathin, Smith, and Deci (1978) found that participants who were asked to choose three puzzles to work on among six options spent more time engaged in the puzzle-solving task in a subsequent free-play period compared to participants who were assigned to work on three of the six puzzles. ...
