Autocommunication - Self-communication - Communicating with oneself: One might actually want to add one (or more) question marks to this title: "Autocommunication?" Does it exist? Can a person direct signs at themselves? Self-talk, diaries, self-reflections, shopping or reminder notes come to mind. But are these phenomena even comprehensible within the paradigm of communication theory? Communication means that one (sender) conveys something to another (receiver), right? Even within the paradigm of autopoietic systems, where there is no transmission of signs, but where each system must construct all meaning itself, questions arise: Is autocommunication a cognitive operation because it is performed by one person alone? Or is it a communicative operation, as its name 'autocommunication' suggests? This volume.
