A Model of Mastery Motivation in Children: Individual Differences and Developmental Change Susan H arte r
Motivational constructs have perennially been at the heart of our theorizing about human behavior. Most recently, the concept of intrinsic motivation has come into vogue. Two general approaches to this topic can be identified. Within the social-psychological camp, experimentalists such as Lepper (this volume) and Deci (1975) and their proponents as well as opponents have focused on a programmatic effort to examine the conditions under which extrinsic rewards undermine intrinsic motivation. In these attributional models, closely wed to a growing data base, a number of parameters that govern the relationship between extrinsic rewards and one’s motivation to perform a given behavior have been identified.
