Contribution
A compact review, not a new result. It puts SDT’s two founding mini-theories in one place. Cognitive evaluation theory (CET) accounts for what raises and lowers intrinsic motivation. Organismic integration theory (OIT) accounts for how extrinsic regulations are internalized and how far. The paper then adds the step that unifies them: both sets of findings are read as effects of satisfying or thwarting three basic needs, and need satisfaction is tied directly to well-being, including within-person, day-to-day.
Key insight
The question about a motive is not how strong it is but whose it is. Two students can both do their homework, one “because they personally grasp its value for their chosen career”, the other “only because they are adhering to their parents’ control” (p. 71). Both are extrinsically motivated and both are intentional, but they differ in relative autonomy, and the difference predicts persistence, quality of performance and well-being. Autonomy for a non-interesting act is achieved by internalization, and how far internalization goes depends on whether the context supports autonomy.
Assumptions
- An organismic metatheory. People have “evolved inner resources” and “inherent growth tendencies” (p. 68). The theory does not explain why intrinsic motivation exists (“an evolved propensity”, p. 70), only what sustains or diminishes it.
- Intrinsic motivation applies only to activities that hold intrinsic interest. “For activities that do not hold such appeal, the principles of CET do not apply” (p. 71). Cameron, Banko and Pierce’s 2001 reply (LIT-562, read since in NOTE-587) reports that rewards enhance free choice on low-interest tasks (0.28), so the scope condition matters to the dispute.
- Self-reported reasons measure regulation. The continuum’s evidence is Ryan and Connell’s (1989) self-report reasons, whose subscales correlate in a “quasi-simplex pattern” (p. 73).
- Universality. The three needs are “innate, essential, and universal” (p. 74). Their modes of satisfaction are not.
Key results
The paper reports others’ results. Its main claims, with its pages:
- CET (pp. 70–71). Competence-supporting events (optimal challenge, positive feedback) enhance intrinsic motivation only with “a sense of autonomy”, an internal perceived locus of causality. Tangible rewards, threats, deadlines, directives, pressured evaluations and imposed goals undermine it. Choice and acknowledgement of feelings enhance it. The reward meta-analysis of Deci, Koestner and Ryan (LIT-557) is said to have “confirmed, in spite of claims to the contrary by Eisenberger and Cameron (1996), that all expected tangible rewards made contingent on task performance do reliably undermine intrinsic motivation” (p. 70).
- Relatedness (p. 71). Its role in intrinsic motivation is “distal”: a secure base, not a proximal requirement.
- OIT and the continuum (pp. 71–73). Amotivation, external regulation, introjection, identification, integration, intrinsic motivation. External and introjected regulation are sometimes combined as “controlled”, and identified, integrated and intrinsic as “autonomous”. Internalization is not a stage sequence: a new regulation can be internalized “at any point along this continuum” (p. 73).
- Outcomes of internalization (p. 73). Introjection goes with effort but also anxiety and poor coping with failure. Identification goes with interest, enjoyment and positive coping. In health care, more internalized regulation goes with medication adherence, maintained weight loss, glucose control and attendance in addiction treatment.
- What fosters integration (pp. 73–74). Relatedness and competence support internalization. Contexts “can yield autonomous regulation only if they are autonomy supportive”. In Deci, Eghrari, Patrick and Leone (1994), controlling contexts yielded internalization “only introjected”.
- Autonomy is not independence (p. 74). Autonomy “refers … to the feeling of volition that can accompany any act, whether dependent or independent, collectivist or individualist”.
- Needs and well-being (pp. 74–76). Intrinsic aspirations (growth, relationships, community) predict well-being; extrinsic aspirations (wealth, fame, image) predict lower well-being, and attaining them does not help (T. Kasser & Ryan; replicated in Russia). Daily fluctuations in each need’s satisfaction independently predict daily well-being (Reis et al.). Contexts that set needs against each other, “as when a child is required by parents to give up autonomy in order to feel loved”, set up “alienation and psychopathology” (p. 75).
Claims
| id | claim | strength | support |
|---|---|---|---|
| C1 | Autonomy-supportive versus controlling events raise versus lower intrinsic motivation, through perceived locus of causality | strong (stated as the theory’s core; many cited experiments) | pp. 70–71; Deci et al. 1999 |
| C2 | Extrinsic motivation varies in relative autonomy along a single continuum | moderate | Ryan & Connell’s quasi-simplex, p. 73 |
| C3 | Autonomy support is required for integration; relatedness and competence alone yield at most introjection | moderate | Deci et al. 1994 and correlational field studies, pp. 73–74 |
| C4 | More internalized regulation predicts better persistence, performance and health behaviour | moderate (correlational in the main) | p. 73 |
| C5 | Autonomy is volition, compatible with dependence and collectivism | definitional, with cited support (Kim et al.; Ryan & Lynch) | p. 74 |
| C6 | The three needs are universal and essential to well-being | moderate as stated; the within-person diary studies are the strongest support offered | pp. 74–76 |
| C7 | Need deprivation is a principal source of distress and psychopathology | weak here: asserted, cited to Ryan, Deci & Grolnick 1995 | p. 74 |
Concepts
- intrinsic motivation: “the inherent tendency to seek out novelty and challenges, to extend and exercise one’s capacities, to explore, and to learn” (p. 70); doing an activity “for the inherent satisfaction of the activity itself” (p. 71).
- extrinsic motivation: “the performance of an activity in order to attain some separable outcome” (p. 71).
- internalization / integration: “Internalization refers to people’s ‘taking in’ a value or regulation, and integration refers to the further transformation of that regulation into their own so that, subsequently, it will emanate from their sense of self” (p. 71).
- introjected regulation: regulation “taken in” but “not fully accepted as one’s own”; “regulation by contingent self-esteem” (p. 72).
- identified regulation: “a conscious valuing of a behavioral goal or regulation, such that the action is accepted or owned as personally important” (p. 72).
- integrated regulation: identified regulations “fully assimilated to the self”, i.e. “evaluated and brought into congruence with one’s other values and needs” (p. 73).
- amotivation: “lacking the intention to act” (p. 72).
- perceived locus of causality: deCharms’s internal versus external attribution of the cause of one’s action (pp. 70, 72).
- basic need: an energizing state whose satisfaction conduces to health and whose frustration contributes to pathology (p. 74).
Connections
- Deci & Ryan (2000), LIT-558. The long version of the same theory, published the same year, with the definition of needs argued against Hull and Murray, the self, need thwarting and evolution.
- Deci, Koestner & Ryan (1999), LIT-557. The meta-analysis this paper cites as settling the reward question. The dispute it settles is with Eisenberger and Cameron (1996), the reworked form of Cameron and Pierce (1994), LIT-556.
- Bandura (1977), LIT-545, unread. The paper names self-efficacy twice: autonomous motivation predicts better outcomes even at equal self-efficacy (p. 69), and not feeling competent is one source of amotivation (p. 72, citing Bandura 1986). Self-efficacy is SDT’s perceived competence, and is treated as necessary, not sufficient.
- The record’s Frankfurt holdings (LIT-293, NOTE-264; THEORY-029, THEORY-040). No philosopher is cited here, but the continuum answers a question they ask. Frankfurt distinguishes desires a person identifies with from those that are “ours in a gross literal sense” but externalized (NOTE-264, §§5–6). SDT’s introjection is regulation “within the person” that has not become part of “the self”, and it is placed by degree on a continuum, not by the order of an endorsing attitude. Ryan and Deci draw the comparison themselves in 2006 (LIT-560).
Bearing on the record
- The empirical counterpart of THEORY-029. That account says no higher-order attitude makes a motive one’s own by its order alone. SDT places ownership in integration, the congruence of a regulation “with one’s other values and needs” (p. 73), and makes it graded. It says nothing about order. It does not escape Velleman’s dilemma either: “the self” with which a regulation is integrated is specified, in this paper, only through the integrating process. The 2000 target article (LIT-558) supplies the organismic account of the self that would have to carry that weight.
- A historical condition for THEORY-040. SDT makes the social history of internalization matter: the same behaviour, internalized under control, is introjected; under autonomy support, it can be integrated (pp. 73–74). That is a condition on how an attitude came to be held. The paper does not consider manipulation, and its measures are present self-reports.
- No ML instruction. Nothing here belongs in the anthology.
Limitations
- A review: every empirical claim is cited to other work, and no effect sizes are given except by reference.
- The continuum rests largely on self-reported reasons. The paper does not discuss whether people can report the source of their regulation.
- Integrated regulation is defined but rarely measured separately: “In some studies, identified, integrated, and intrinsic forms of regulation have been combined” (p. 73).
- “Universal” needs are supported here by samples from the United States, Russia and Korea. The cultural argument is that modes of satisfaction vary while the needs do not, which makes the universality claim hard to falsify without a measure of need satisfaction independent of well-being.
Open questions
- Can integrated regulation be measured apart from identified regulation and intrinsic motivation? If not, the top of the continuum is a definition.
- Is the need for relatedness proximal or distal for intrinsic motivation? The paper calls it distal (p. 71) but central for internalization (p. 73).
- What evidence would show that a need is not basic? The 2020 review (LIT-561) states criteria.

Note of 2026-11-03: attainment, read first-hand
Niemiec et al. 2009 (NOTE-1520), the direct test, show extrinsic attainment adding nothing to well-being only with intrinsic attainment in the same model (β = .00 on well-being, .38 on ill-being). On its own extrinsic attainment correlates positively with well-being (mean r = .19) and with need satisfaction (.18).
