Deci & Ryan's SDT is the first hyperlink in this post. Also note the reference at the bottom of the image:

Deci, E., & Ryan, R. (1991). A motivational approach to self: Integration in personality.
In R. Dienstbier (Ed.), Nebraska symposium on motivation: Vol. 38. Perspectives on motivation (pp. 237–288). Lincoln: University of Nebraska Press.

It's always best to read first, and criticize later.
