The fields of religious and motivation psychology have quite independently developed their own conceptualizations and research agendas. Few scholars, however, have examined issues that are at the intersection of both fields and, if so, most researchers in the psychology of religion did not make use of existing general motivational frameworks to enrich their understanding of the motivational dynamics for religious behaviors. The aim of the present chapter is to indicate how self-determination theory (Ryan & Deci, (2000a) American Psychologist, 55, 68-78) might help to further refine Allport's classical distinction between intrinsic and extrinsic religious orientation. Specifically, it is argued that the reasons or regulations for religious behavior (initially, intrinsic vs. extrinsic; later, autonomous vs. controlled) and the goals of religious behavior (intrinsic vs. extrinsic), as they are defined within self-determination theory, are not distinguished within Allport's and other researchers' frameworks. Both conceptual dimensions might better be disentangled, so that their independent effects could be studied.
