Nature and mechanisms of loss of motivation

Loss of motivation refers either to the weakening of a motive q or to the loss of energy and persistence with which some subordinate goal p is planned for and pursued in view of q. Although interrelated, such aspects can be kept distinct, and the present work focuses on the loss of strength of the subordinate goal. An analysis is provided of such mental attitudes as subjective frustration, negative expectation, disappointment, and discouragement so as to clarify their respective roles in favoring loss of motivation. The necessary cognitive conditions for the occurence of loss of motivation are singled out; namely, goal p should be an intention, and a disappointment should occur in regard to the instrumental relationship between p and q, p's attainability, or p's convenience. Both advantages and limits of the model are discussed.
