Intrinsic motivation has been operationally defined in various ways, al- though there have been two measures that have been most often used. Basic experimental research (e.g., Deci, 1971) has rested primarily on a behavioral measure of intrinsic motivation called the ‘‘free choice’’ measure. In experiments using this measure participants are exposed to a task under varying conditions (e.g., getting a reward or not). Following this period, the experimenter tells participants they will not be asked to work with the target task any further, and they are then left alone in the experimental room with the target task as well as various distractor activities. They thus have a period of ‘‘free choice’’ about whether to return to the activity, and it is assumed that, if there is no extrinsic reason to do the task (e.g., no reward and no approval), then the more time they spend with the target task, the more intrinsically motivated they are for that task. This measure has been the mainstay through which the dynamics of intrinsic motivation have been experimentally studied.
The other common approach to the measurement of intrinsic motivation is the use of self-reports of interest and enjoyment of the activity per se. Experimental studies typically rely on task-specific measures (e.g. Ryan, 1982; Harackiewicz, 1979). Most field studies have instead used more general, ‘‘domain’’ focused measures, such as one’s intrinsic motivation for school
