Self-determination theory (Deci & Ryan, 1985) posits that (a) people a
re inherently motivated to internalize the regulation of uninteresting
though important activities; (b) there are two different processes th
rough which such internalization can occur, resulting in qualitatively
different styles of self-regulation; and (c) the social context influ
ences which internalization process and regulatory style occur. The tw
o types of internalization are introjection, which entails taking in a
value or regulatory process but not accepting it as one's own, and in
tegration, through which the regulation is assimilated with one's core
sense of self. Introjection results in internally controlling regulat
ion, whereas integration results in self-determination. An experiment
supported our hypothesis that three facilitating contextual factors-na
mely, providing a meaningful rationale, acknowledging the behaver's fe
elings, and conveying choice-promote internalization, as evidenced by
the subsequent self-regulation of behavior. This experiment also suppo
rted our expectation that when the social context supports self-determ
ination, integration tends to occur, whereas when the context does not
support self-determination, introjection tends to occur.
