Based on the results from earlier animal and human studies regarding intrinsic motivation the author explored two possibilities. In the first two experiments he looked at the effect of extrinsic rewards in terms of a decrease in intrinsic motivation to perform a task. Earlier studies showed contradictory or inconclusive findings regarding decrease in performance on a task following an external reward.
The third experiment was based on findings of developmental learning theorists and looked at whether a different type of reward enhances intrinsic motivation to participate in an activity. This experiment tested the hypothesis that if an individual is intrinsically motivated to perform an activity, introduction of an extrinsic reward decreases the degree of intrinsic motivation to perform the task.
Each group participated in three sessions conducted on three different days. During the sessions, participants were engaged in working on a Soma cube puzzle—which the experimenters assumed was an activity college students would be intrinsically motivated to do. The puzzle could be put together to form numerous different configurations. In each session, the participants were shown four different configurations drawn on a piece of paper and were asked to use the puzzle to reproduce the configurations while they were being timed.
The first and third session of the experimental condition were identical to control, but in the second session the participants in the experimental condition were given a dollar for completing each puzzle within time. During the middle of each session, the experimenter left the room for eight minutes and the participants were told that they were free to do whatever they wanted during that time, while the experimenter observed during that period.
The amount of time spent working on the puzzle during the free choice period was used to measure motivation. As Deci expected, when external reward was introduced during session two, the participants spent more time working on the puzzles during the free choice period in comparison to session 1 and when the external reward was removed in the third session, the time spent working on the puzzle dropped lower than the first session.
All subjects reported finding the task interesting and enjoyable at the end of each session, providing evidence for the experimenter's assumption that the task was intrinsically motivating for the college students.
The study showed some support of the experimenter's hypothesis and a trend towards decrease in intrinsic motivation was seen after money was provided to the participants as external reward. The second experiment was a field experiment, similar to laboratory Experiment I, but was conducted in a natural setting.
Eight student workers were observed at a college biweekly newspaper. Four of the students served as a control group and worked on Friday. The experimental group worked on Tuesdays.
The control and experimental group students were not aware that they were being observed. The week observation was divided into three time periods. The task in this study required the students to write headlines for the newspaper.
During "Time 2", the students in the experimental group were given 50 cents for each headline they wrote. At the end of Time 2, they were told that in the future the newspaper cannot pay them 50 cent for each headline anymore as the newspaper ran out of the money allocated for that and they were not paid for the headlines during Time 3.
The speed of task completion headlines was used as a measure of motivation in this experiment. Absences were used as a measure of attitudes. To assess the stability of the observed effect, the experimenter observed the students again Time 4 for two weeks.
There was a gap of five weeks between Time 3 and Time 4. Due to absences and change in assignment etc. The results of this experiment were similar to Experiment I and monetary reward was found to decrease the intrinsic motivation of the students, supporting Deci's hypothesis. Experiment III was also conducted in the laboratory and was identical to Experiment I in all respects except for the kind of external reward provided to the students in experimental condition during Session 2.
The experimenter hypothesized that a different type of reward—i. The results of the experiment III confirmed the hypothesis and the students' performance increased significantly during the third session in comparison to session one, showing that verbal praise and positive feedback enhances performance in tasks that a person is initially intrinsically motivated to perform. This provides evidence that verbal praise as external reward increases intrinsic motivation.
The author explained differences between the two types of external rewards as having different effects on intrinsic motivation. When a person is intrinsically motivated to perform a task and money is introduced to work on the task, the individual cognitively re-evaluates the importance of the task and the intrinsic motivation to perform the task because the individual finds it interesting shifts to extrinsic motivation and the primary focus changes from enjoying the task to gaining financial reward.
However, when verbal praise is provided in a similar situation increases intrinsic motivation as it is not evaluated to be controlled by external factors and the person sees the task as an enjoyable task that is performed autonomously.
The increase in intrinsic motivation is explained by positive reinforcement and an increase in perceived locus of control to perform the task. Pritchard, Campbell and Campbell  conducted a similar study to evaluate Deci's hypothesis regarding the role of extrinsic rewards on decreasing intrinsic motivation.
Participants were randomly assigned to two groups. A chess-problem task was used in this study. Data was collected in two sessions. Participants were asked to complete a background questionnaire that included questions on the amount of time the participant played chess during the week, the number of years that the participant has been playing chess for, amount of enjoyment the participant gets from playing the game, etc. The participants in both groups were then told that the experimenter needed to enter the information in the computer and for the next 10 minutes the participant were free to do whatever they liked.
The experimenter left the room for 10 minutes. The room had similar chess-problem tasks on the table, some magazines as well as coffee was made available for the participants if they chose to have it. The time spent on the chess-problem task was observed through a one way mirror by the experimenter during the 10 minutes break and was used as a measure of intrinsic motivation. After the experimenter returned, the experimental group was told that there was a monetary reward for the participant who could work on the most chess problems in the given time and that the reward is for this session only and would not be offered during the next session.
The control group was not offered a monetary reward. After a filler task, the experimenter left the room for 10 minutes and the time participants spent on the chess-problem task was observed. The experimental group was reminded that there was no reward for the task this time. After both sessions the participants were required to respond to questionnaires evaluating the task, i.
Both groups reported that they found the task interesting. The results of the study showed that the experimental group showed a significant decrease in time spent on the chess-problem task during the minute free time from session 1 to session 2 in comparison to the group that was not paid, thus confirming the hypothesis presented by Deci that contingent monetary reward for an activity decreases the intrinsic motivation to perform that activity.
Other studies were conducted around this time focusing on other types of rewards as well as other external factors that play a role in decreasing intrinsic motivation. Principles of SDT have been applied in many domains of life, e. Murcia, Roman, Galindo, Alonso and Gonzalez-Cutre  looked at the influence of peers on enjoyment in exercise. Specifically, the researchers looked at the effect of motivational climate generated by peers on exercisers by analyzing data collected through questionnaires and rating scales.
The assessment included evaluation of motivational climate, basic psychological needs satisfaction, levels of self-determination and self-regulation amotivation, external, introjected, identified and intrinsic regulation and also the assessment of the level of satisfaction and enjoyment in exercising.
Data analysis revealed that when peers are supportive and there is an emphasis on cooperation, effort, and personal improvement, the climate influences variables like basic psychological needs, motivation and enjoyment.
The task climate positively predicted the three basic psychological needs competence, autonomy and relatedness and so positively predicted self-determined motivation. Task climate and the resulting self-determination were also found to positively influence level of enjoyment the exercisers experienced during the activity. Awareness has always been associated with autonomous functioning; however, it was only recently that the SDT researchers incorporated the idea of mindfulness and its relationship with autonomous functioning and emotional wellbeing in their research.
Brown and Ryan  conducted a series of five experiments to study mindfulness: They defined mindfulness as open, undivided attention to what is happening within as well as around oneself. From their experiments, the authors concluded that when individuals act mindfully, their actions are consistent with their values and interest.
Also, there is a possibility that being autonomous and performing an action because it is enjoyable to oneself increases mindful attention to one's actions. Another area of interest for SDT researchers is the relationship between subjective vitality and self-regulation. Ryan and Deci  define vitality as energy available to the self, either directly or indirectly, from basic psychological needs. This energy allows individuals to act autonomously.
Many theorists have posited that self-regulation depletes energy but SDT researchers have proposed and demonstrated that only controlled regulation depletes energy, autonomous regulation can actually be vitalizing. A recent study by Hyungshim Jang  in which the capacity of two different theoretical models of motivation were used to explain why an externally provided rationale for doing a particular assignment often helps in a student's motivation, engagement, and learning during relatively uninteresting learning activities.
Students who received the rationale showed greater interest, work ethic, and determination. Structural equation modeling was used to test three alternative explanatory models to understand why the rationale produced such benefits:. The data fit all three models; but only the model based on self-determination theory helped students to engage and learn.
Findings show the role that externally provided rationales can play in helping students generate the motivation they need to engage in and learn from uninteresting, but personally important, material. The importance of these findings to those in the field of education is that when teachers try to find ways to promote student's motivation during relatively uninteresting learning activities, they can successfully do so by promoting the value of the task.
One way teachers can help students value what they may deem "uninteresting" is by providing a rationale that identifies the lesson's otherwise hidden value, helps students understand why the lesson is genuinely worth their effort, and communicates why the lesson can be expected to be useful to them.
An example of SDT and education are Sudbury Model schools where people decide for themselves how to spend their days. In these schools, students of all ages determine what they do, as well as when, how, and where they do it.
This freedom is at the heart of the school; it belongs to the students as their right, not to be violated. The fundamental premises of the school are simple: In practice this means that students initiate all their own activities and create their own environments. The physical plant, the staff, and the equipment are there for the students to use as the need arises. The school provides a setting in which students are independent, are trusted, and are treated as responsible people; and a community in which students are exposed to the complexities of life in the framework of a participatory democracy.
Sudbury schools do not perform and do not offer evaluations, assessments, or recommendations, asserting that they do not rate people, and that school is not a judge; comparing students to each other, or to some standard that has been set is for them a violation of the student's right to privacy and to self-determination. Students decide for themselves how to measure their progress as self-starting learners as a process of self-evaluation: According to self-determination theory,  individuals who attribute their actions to external circumstances rather than internal mechanisms are far more likely to succumb to peer pressure.
In contrast, individuals who consider themselves autonomous tend to be initiators of actions rather than followers. Research examining the relationship between self-determination theory and alcohol use among college students has indicated that individuals with the former criteria for decision making are associated with greater alcohol consumption and drinking as a function of social pressure.
For instance, in a study conducted by Knee and Neighbors,  external factors in the individuals who claim to not be motivated by internal factors were found to be associated with drinking for extrinsic reasons, and with stronger perceptions of peer pressure, which in turn was related to heavier alcohol use.
Given the evidence suggesting a positive association between an outward motivation and drinking, and the potential role of perceived social influence in this association, understanding the precise nature of this relationship seems important.
Further, it may be hypothesized that the relationship between self-determination and drinking may be mediated to some extent by the perceived approval of others. Motivational interviewing MI is a popular approach to positive behavioral change. It is a client-centered method that doesn't persuade or coerce patients to change and instead attempts to explore and resolve their ambivalent feelings, which allows them to choose themselves whether to change or not.
They believe that MI provides an autonomy-supportive atmosphere, which allows clients to find their own source of motivation and achieve their own success in terms of overcoming addiction. Patients randomly assigned to an MI treatment group found the setting to be more autonomy-supportive than those in a regular support group.
Several studies explored the link between self-determination theory and environmental behaviors to determine the role of intrinsic motivation for environmental behavior performance and to account for the lack of success of current intervention strategies. Environmental attitudes and knowledge are not good predictors of behavior. Self-determination theory suggests that motivation can predict behavior performance.
Each item is scored on a Likert scale. The Amotivation toward the Environment Scale measures the four reasons for amotivation by answering a question 'Why are you not doing things for the environment? The participants rank 16 total statements four in each category of amotivation on a Likert scale. Intervention strategies have to be effective in bridging the gap between attitudes and behaviors.
Monetary incentives, persuasive communication, and convenience are often successful in the short term, but when the intervention is removed, behavior is discontinued. In the long run, such intervention strategies are therefore expensive and difficult to maintain.
Self-determination theory explains that environmental behavior that is not motivated intrinsically is not persistent. On the other hand, when self-determination is high, behavior is more likely to occur repeatedly. The importance of intrinsic motivation is particularly apparent with more difficult behaviors. While they are less likely to be performed in general, people with high internal motivation are more likely to perform them more frequently than people with low intrinsic motivation.
According to Osbaldiston and Sheldon , autonomy perceived by an individual leads to an increased frequency of environmental behavior performance. In their study, university students chose an environmental goal and performed it for a week. Perceived autonomy, success in performing chosen behavior, and their future intention to continue were measured. The results suggested that people with higher degree of self-perceived autonomy successfully perform behaviors and are more likely to do so in the long term.
