Editing Intrinsic Motivation (section)

==Evidence==
Some of the earliest evidence to support intrinsic motivation actually comes from research on animal behavior that showed that exploration is an activity that reinforces itself, that is, it could be considered intrinsically motivated. <ref>Dashiell, J. F. A quantitative demonstration of animal drive. Journal of Comparative Psychology, 1925, 5, (pp. 205–208). </ref>Dashiell and <ref>Nissen, H. W. A study of exploratory behavior in the white rat by means of the obstruction method. Journal of Genetic Psychology, 1930, 87, (pp. 361–376). </ref>Nissen (as cited in <ref name="deci" />Deci) demonstrated through their experiments on rats that the subjects endured electric shocks to explore novel stimuli in a maze. 

In his research, <ref>deCharms, R. (1968). Personal causation: The internal affective determinants of behavior. New York: Academic Press.</ref><ref>deCharms, R. (1976). Enhancing motivation: Change in the classroom. New York: Irvington.</ref>deCharms (as cited in <ref name="csiks" />Csikszentmihalyi & Nakamura) found that school children who felt in control of their lives and had high intrinsic motivation, or ''Origins'', as he called them, showed more accountability for their behavior and enjoyed it regardless of external rewards. In comparison, ''Pawns'', or children who did not feel in control of their lives did not demonstrate such behavior. 

<ref name="deci" />Deci’s research (as cited in <ref name="csiks" />Csikszentmihalyi & Nakamura) agreed with this hypothesis and showed that if people were given rewards such as money for things they enjoyed when this reward was taken away they lost interest in these activities faster than when there was no extrinsic reward involved.
