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.
David Kantor
David Kantor, (b. 1927) is an American systems psychologist, organizational consultant, and clinical researcher. He is the founder of three research and training institutes, the author of numerous books and articles, and the inventor of a series of psychometric instruments that provide insight into individual and group behaviors. His groundbreaking empirical research revealed a fundamental structure to all communication, known as Structural Dynamics, which provides the solution to the most common communication challenges experienced in any human system. Kantor’s Four Player Model has been referenced by hundreds of other theorists including Peter Senge in The Fifth Discipline, Bill Isaacs in Dialogue: The Art of Thinking Together, and Michael Jensen and Werner Erhard in their revolutionary leadership program: Being a Leader and the Effective Exercise of Leadership as Your Natural Self Expression. His work has made a significant contribution to both family systems therapy and organizational theory and practice.
