As previously stated, motivation is a
multidimensional construct. It is fluid and represents a continuum from amotivation to intrinsic
motivation. Organismic Integration Theory (OIT) is another sub-theory of SDT that is focused
upon the fluid process of internalization of motivation. Internalization is the process by which
one takes external motivators and makes these his or her own (Deci & Ryan, 1985). The
continuum begins with amotivation, and then moves through the four regulations of extrinsic
motivation represented in OIT. The first stage is called external regulation. External regulation
is characterized by one acting in order to gain rewards or avoid the consequences of the action.
This is the least self-determined form of extrinsic motivation (Deci & Ryan, 1985).
