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.
Dialogical self
Given the basic assumption of the extended self, the other is not simply outside the self but rather an intrinsic part of it. There is not only the actual other outside the self, but also the imagined other who is entrenched as the other-in-the-self. An important theoretical implication is that basic processes, like self-conflicts, self-criticism, self-agreements, and self-consultancy, are taking place in different domains in the self: within the internal domain (e.g., "As an enjoyer of life I disagree with myself as an ambitious worker"); between the internal and external (extended) domain (e.g., "I want to do this but the voice of my mother in myself criticizes me") and within the external domain (e.g., "The way my colleagues interact with each other has led me to decide for another job").
