A projective assessment of autonomous motivation in children: Correlational and experimental evidence

This article presents two studies aimed at validating a new TAT-like projective measure of autonomous motivation in children. Study 1 assesses the validity of the new measure by correlating it with self-report questionnaires of autonomous motivation, positive and negative affect, task value and mastery goal orientation. Study 2 is an experiment in which autonomous motivation is manipulated and then assessed with the new projective measure and with a self-report scale. Results of both studies support the validity of the new projective measure. In study 2, regression analysis suggests that the new projective measure is sensitive to aspects of experimentally induced autonomous motivation that are not captured by a self-report measure.
