If you are a regular visitor of Mappalicious, you know by now that I´m a big fan of Self-Determination Theory and adjacent frameworks such as Self-Concordance Theory. These concepts have been developed roughly at the same time as central tenets of Positive Psychology – without necessarily being regarded as “part of” Positive Psychology (don´t ask me why, I guess it´s just a consequence of different research agendas/”brand building”).
Recently, I stumbled upon a TEDx talk given by Edward Deci where he explains the foundations of SDT. In addition, there´s a nice intro to the framework by Richard Ryan given at a SDT conference. Listening to the two SDT co-founders will give you a great and lively overview of the core concepts and some of its applications. Enjoy!
