theory of personal investment
a motivational theory stating that the degree to which an individual will invest personal resources of time and effort in an activity, in anticipation of benefits, is a function of personal incentives (mastery orientation, competitive orientation, affiliation, status); beliefs about oneself (sense of competence, self-reliance, goal-directedness, identity); and perceived options (behavioral choices seen as available in the specific situation). [proposed in 1986 by U.S. psychologists Martin L. Maehr (1932– ) and Larry A. Braskamp]
