Dialogical self
Inspired by the original ideas of William James and Mikhail Bakhtin, Hubert Hermans, Harry Kempen and Rens van Loon wrote the first psychological publication on the "dialogical self" in which they conceptualized the self in terms of a dynamic multiplicity of relatively autonomous "I"-positions in the (extended) landscape of the mind. In this conception, the "I" has the possibility to move from one spatial position to another in accordance with changes in situation and time. The "I" fluctuates among different and even opposed positions, and has the capacity to imaginatively endow each position with a voice so that dialogical relations between positions can be established. The voices function like interacting characters in a story, involved in processes of question and answer, agreement and disagreement. Each of them have a story to tell about their own experiences from their own stance. As different voices, these characters exchange information about their respective Me's and mines, resulting in a complex, narratively structured self.
Constructive developmental framework
Dialectical thinking has its roots in Greek classical philosophy but is also found in ancient Hindu and Buddhist philosophy, and relates to the search for truth through reasoned argument. It finds its foremost expression in the work of the German philosopher Georg Hegel. Essentially, dialectics is viewed as the system by which human thought attempts to capture the nature of reality. Building on Bhaskar and Basseches, CDF uses a framework for dialectical thinking based on the idea that everything in reality is transient and composed of contradictions, part of a larger whole, related in some way to everything else, and subject to sudden transformation. This framework therefore distinguishes dialectical thinking in terms of four classes of dialectical thought forms that can be said to define reality:In addition, CDF distinguishes seven individual thought forms for every class, making a total of 28 thought forms, representing a re-formulation of Basseches' 24 schematas.
