This chapter focuses on three primary models for understanding motivation during transitions and addresses: (1) Expectancy × Value theory, (2) cognitive models for motivation and in particular attribution theory, locus of control, and taxonomy of perceived causes; and (3) intrinsic/extrinsic motivation theory and the self-determination model. We focus specifically on the ways in which intrinsic and extrinsic motivation influence human behavior. Individuals who are repeatedly successful in making a transition will more often demonstrate motivation intrinsically in decisions to make a transition. We examine the role of achievement motivation, need for autonomy, need for competency, search for satisfaction, and need for affiliation and relatedness as motivators for career change. They are discussed in light of the retrospective interviews with twenty-four elite performers in three domains (business, sports, and music) who successfully and repeatedly transitioned to higher positions within their field.
