Conversation theory is a pedagogical, dialectical, and cybernetic framework that examines conversation, cognition and learning in the context of two conversational participants who attempt to establish what is meant by a topic during a conversation. In effect, each participant attempts to converge towards a common understanding with the other as to the significance of the said topic between themselves. The theory provides a formal dialectical framework that examines how conversational participants may modulate the conceptualisation processes of each participant throughout a conversational interaction. A conversational interaction is characterised as a shared learning process: Each participant takes turns within the interaction—switching at intervals between the role of a student or the role of a teacher—to achieve a state of mutual understanding between themselves. In this sense, the theory concerns itself with how two a priori asynchronous cognitive systems—either mechanical or organic in nature—are able to converse and conceptualise about a topic, in such a way that each system achieves the a posteriori synchronization of each cognitive system's particular perspective or attitude towards said topic. This resultant synchronization allows each conversational participant to satisfy some shared task or goal. Conversation theory provides an experimental framework that heavily utilizes both human-computer interaction frameworks and computer-theoretic models, in order to create a testable framework explaining how conversational interactions may lead to the emergence of shared knowledge between participants. The theory was developed by Gordon Pask, who worked with Bernard Scott, Dionysius Kallikourdis, Robin McKinnon-Wood, and others during its initial development and implementation. With Ranulph Glanville and Paul Pangaro also contributing to the application and implementation of the framework in subsequent periods.
== Overview == Conversation theory is a formal theory—with practical applications—describing how conversation modulates conceptualisation processes between conversational participants. Both experimentation and learning exercises are enacted in the practical application of the theory, in order to verify if a consensus has been established between conversational participants in relation to some aim or goal. The theory prioritizes analysing learning and teaching approaches related to education, rather than other concerns about conversational forms. Historically, Gordon Pask and his associates at System Research Ltd., attempted to examine the learning and intellectual development of conversational participants by means of human-machine interactions; thereby sufficiently providing a psychological framework with educational technological applications. Pask's initial motivation for developing conversation theory, was to study and evaluate the nature of cybernetic inquiry via a cybernetic framework.
=== Conversation === A conversation—in the context of conversation theory—involves a learning exchange between conversational participants. Because of this, participants engaging in a discussion about a subject matter make their knowledge claims explicit through the means of various conversational transactions. Since meanings are agreed during the course of a conversation, and since purported agreements can be illusory—whereby each conversational participant may assume a shared understanding of a given topic with their partner which may then be verified as false—an empirical approach to the study of conversation would require stable reference points during such conversational exchanges between peers so as to permit reproducible results. Using computer theoretical models of cognition, conversation theory can document these intervals of understanding that arise in the conversations between two participating individuals, such that the development of individual and collective understandings can be analysed rigorously. In this way, Pask has been argued to have been an early pioneer in AI-based educational approaches: Having proposed that advances in computational media may enable conversational forms of interactions to take place between man and machine.
==== Strict Conversation ==== The types of languages that conversation theory demarcates in its approach include (i) language regarding the experiment itself and (ii) languages used by the experimental participants during the course of an experiment. Within conversation theory, a dialogue is said to display different modalities: This is based on how an observer chooses to frame a language under observation within the context of an experiment. The types of languages considered in conversation theory are as follows: Natural languages used for general discussions outside of the experiment; object languages which are the subject of inquiry during an experiment, and finally the metalanguage which is used to talk about the design, management, and results on an experiment. For the purposes of experimentation and observation, all conversational transactions within a given interaction under observation take the form of a strict conversation: That is, a conversation where (i) there is an agreement to limit the conversational engagement to a finite number of topics, and (ii) there exists some experimenter who documents each iteration of a participant's ongoing understanding of a given topic during a conversation. Such strict conversations are monitored though a cooperative externalisation technique (CET) which involves participants agreeing to externalise their—normally private—cognitive events within the context of a strictly observable experiment. Each experiment operates under the principle of there existing a CET heuristic. This heuristic refers to the assumption—held by both the experimenter and each participant of the strict conversation—that (i) one participant is able to correctly interpret another participant's understanding of a topic through constructing an explanation of said topic, and (ii) that such an understanding persist for the remainder of a given conversational interaction.
