Conversation theory

Conversation theory is a cybernetic approach to the study of conversation, cognition and learning that may occur between two participants who are engaged in conversation with each other. ^{[1] [2] [3]} It presents an experimental framework heavily utilizing human-computer interactions and computer theoretic models as a means to present a scientific theory explaining how conversational interactions lead to the emergence of knowledge between participants. ^{[4] [5]} The theory was developed by Gordon Pask, who credits Bernard Scott, ^[6] Dionysius Kallikourdis, Robin McKinnon-Wood, ^[7] and others during its initial development and implementation as well as Paul Pangaro during subsequent years. ^{[8] [9] [Footnote 1]}

Overview

Conversation theory may be described as a formal theory of conversational process, ^[10] as well as a theoretical methodology concerned with concept-forming and concept-sharing between conversational participants. ^[11] It may be viewed as a framework that may be used to examine learning and development through the means of conversational techniques by means of human-machine interactions; the results of which may then inform approaches to education, educational psychology, and epistemology. ^[12] While the framework is interpretable as a psychological framework with educational applications (specifically, as a general framework to think about teaching and learning), ^[13] Pask's motivation in developing the theory has been interpreted by some who closely worked with him develop upon certain theoretical concerns regarding the nature of cybernetic inquiry. ^[14]

The theory has been noted to have been influenced by a variety of psychological, pedagogical and philosophical influences such as Lev Vygotsky, R. D. Laing and George H. Mead. ^{[15] [16] [17]} With some authors suggesting that the kind of human-machine learning interactions documented in conversation theory to be mirroring Vygotsky's descriptions of the zone of proximal development, ^[18] and his descriptions of spontaneous and scientific concepts. ^[19]

The theory prioritizes learning and teaching approaches related to education. ^[20] A central idea of the theory is that learning occurs through conversations: For if participant A is to be conscious with participant B of a topic of inquiry, both participants must be able to converse with each other about that topic. ^[21] Because of this, participants engaging in a discussion about a subject matter make their knowledge claims explicit through the means of such conversational interactions.

The theory is concerned with a variety of "psychological, linguistic, epistemological, social or non-commitally mental events of which there is awareness". ^[22] Awareness in this sense is not of a person-specific type, i.e., it is not necessarily localized in a single participant. Instead, the type of awareness examined in conversation theory is the kind of joint awareness that may be shared between entities. ^[22] While there is an acknowledgment of its similarities to phenomenology, the theory extends its analysis to examine cognitive processes. ^[23] However, the concept of cognition is not viewed as merely being confined to an individual's brain or central nervous system. ^[24] Instead, cognition may occur at the level of a group of people (leading to the emergence of social awareness), or may characterize certain types of computing machines. ^[25]

Initial results from the theory lead to a distinction in the type of learning strategies participants used during the learning process; whereby students in general gravitated towards holistic or serialist learning strategies (with the optimal mixture producing a versatile learning strategy). ^[3]

Conversation

Following Hugh Dubberly and Paul Pangaro, ^[26] a conversation in the context of conversation theory involves an exchange between two participants whereby each participant is contextualized as a learning system whose internal states are changed through the course of the conversation. ^[27] What can be discussed through conversation, i.e., topics of discussion, are said to belong to a conversational domain. ^[28]

Conversation is distinguished from the mere exchange of information as seen in information theory, by the fact that utterances are interpreted within the context of a given perspective of such a learning system. ^[27] Each participant's meanings and perceptions change during the course of a conversation, and each participant can agree to commit to act in certain ways during the conversation. ^[29] In this way, conversation permits not only learning but also collaboration through participants coordinating themselves and designating their roles through the means of conversation. ^[30]

Since meanings are agreed during the course of a conversation, and since purported agreements can be illusory (whereby we think we have the same understanding of a given topic but in fact do not), 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 analyzed rigorously. ^[31]

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. ^[32]

Language

The types of languages that conversation theory utilizes in its approach are distinguishable based on a language's role in relation to an experiment in which a conversation is examined as the subject of inquiry; thus, it follows that conversations can be conducted at different levels depending on the role a language has in relation to an experiment. ^[33] The types of languages are as follows: Natural languages used for general discussions outside the experiment; object languages which are the subject of inquiry during an experiment, and finally a metalanguage which is used to talk about the design, management, and results on an experiment.

A natural language ${\displaystyle L^{+}}$ is treated as an unrestricted language used between a source (say a participant) and an interrogator or analyst (say an experimenter). ^[34] For this reason, it may be considered a language for general discussion in the context of conversation theory. An object language ${\displaystyle L}$ meanwhile, has some of the qualities of a natural language (which permits commands, questions, ostentation and predication), ^[35] but is used in conversation theory specifically as the language studied during experiments. ^[36] Finally, the metalanguage ${\displaystyle L^{*}}$ is an observational language used by an interrogator or analysis for describing the conversational system under observation, prescribing actions that are permitted within such a system, and posing parameters regarding what may be discussed during an experiment under observation. ^[35]

The object language ${\displaystyle L}$ differs from most formal languages, by virtue of being "a command and question language[,] not an assertoric language like [a] predicate calculus". ^[37] Moreover, ${\displaystyle L}$ is a language primarily dealing with metaphors indicating material analogies and not on the kind of propositions dealing with truth or falsity values. ^[37] Since conversation theory specifically focuses on learning and development within human subjects, the object language is separated into two distinct modes of conversing.

Conversation theory conceptualises learning as being the result of two integrated levels of control: The first level of control is designated by ${\displaystyle Lev\;0}$ and designates a set of problem-solving procedures which attempt to attain goals or subgoals, whereas the second level of control is designated as ${\displaystyle Lev\;1}$ and denotes various constructive processes that have been acquired by a student through maturation, imprinting and previous learning. ^[38] The object language ${\displaystyle L}$ then is demarcated in conversation theory based on these considerations, whereby it is split between ${\displaystyle L^{0}}$ and ${\displaystyle L^{1}}$ lines of inquiry such that an object language is the ordered pair of such discourse types ${\displaystyle L=\langle L^{0},L^{1}\rangle }$. According to Bernard Scott, ${\displaystyle L^{0}}$ discourse of an object language may be conceptualized as the level of how, i.e., discourse that is concerned with "how to “do” a topic: how to recognize it, construct it, maintain it and so on". ^[39] Meanwhile, ${\displaystyle L^{1}}$ discourse may be conceptualized as the level of why, i.e., it is discourse "concerned with explaining or justifying what a topic means in terms of other topics". ^[39]

Concepts

A concept in conversation theory, is conceived of as the production, reproduction, and maintenance of a given topic relation ${\displaystyle R_{i}}$ from other topic relations ${\displaystyle R_{j}}$, all belonging to a given conversational domain ${\displaystyle R}$. ^{[40] [41]} This implies ${\displaystyle R_{i},R_{j}\in R}$, where ${\displaystyle i}$ and ${\displaystyle j}$ are used to represent a number on a finite index of numbers. A concept must satisfy the twin condition that it must entail ${\displaystyle R_{i}\vdash R_{j}}$ and be entailed ${\displaystyle R_{j}\vdash R_{i}}$ by other topics. ^[42]

A concept in the context of conversation theory is not a class, nor description of a class, nor a stored description: Instead, a concept is specifically used to reconstruct, reproduce or stabilize relations. ^[43] Thus, if ${\displaystyle R_{H}}$ is the head topic of discussion, then ${\displaystyle CON(R_{H})\rightarrow R_{H}}$ implies that the concept of that relation produces, reproduces, and maintains that relation. ^[44]

Now, a concept itself is considered to consist of the ordered pair containing a program and an interpretation:

${\displaystyle CON\triangleq \langle PROG,INTER\rangle }$

Whereby a program attempts to derive a given topic relation, while an interpretation refers to the compilation of that program. ^[44] In other words, given a specific topic relation, a program attempts to derive that relation through a series of other topic relations, which are compiled in such a way as to derive the initial topic relation. ^[44] A concept as defined above is considered to be a ${\displaystyle L}$-procedure, which is embodied by an underlying processor called a ${\displaystyle L}$-processor. ^[44]

In this way, Pask envisages concepts as mental organisations that hold a hypothesis and seek to test that hypothesis in order to confirm or deny its validity. ^[45] This notion of a concept has been noted as formally resembling a TOTE cycle discussed by Miller, Galanter and Pribram. ^{[46] [Footnote 2]} The contents and structure that a concept might have at a given interaction of its continuous deformation can be represented through an entailment structure.

Such conceptual forms are said to be emergent through conversational interactions. They are encapsulated through entailment structures, which is a way by which we may visualize an organized and publicly available collection of resultant knowledge. ^[47] Entailment structures may afford certain advantages compared to certain semantic network structures, as they force semantic relations to be expressed as belonging to coherent structures. The entailment structure is composed of a series of nodes and arrows representing a series of topic relations and the derivations of such topic relations. For example:

In the above illustration, let ${\displaystyle TPQ\in \{R_{i}\}}$, such that there are topic relations that are members of a set of topic relations. Each topic relation is represented by a node, and the entailment represented by the black arc. It follows that ${\displaystyle \langle P,Q\rangle \vdash T}$ in the case above, such that the topics P and Q entail the topic of T.

Assuming we use the same derivation process for all topics in above entailment structure, then we are let with the following product as illustrated above. This represents a minimal entailment mesh consisting of a triad of derivations: ${\displaystyle \langle P,Q\rangle \vdash T}$, ${\displaystyle \langle T,Q\rangle \vdash P}$, and ${\displaystyle \langle P,T\rangle \vdash Q}$. The solid arc indicates that a given head topic relation is derived from subordinate topics, whereas the arcs with dotted lines represent how the head topic may be used to derive other topics. Finally:

Represents two solid arcs permitting alternative derivations of the topic T. This can be expressed as ${\displaystyle \langle P,Q\rangle \lor \langle R,S\rangle \vdash T}$, which reads either the set containing P and Q, or the set containing R and S entail T. Lastly, a formal analogy is shown where two topics T and T' belonging to two entailment meshes are demonstrated to have a one-to-one correspondence with each other. The diamond shape ${\displaystyle R}$ below denotes analogy relation that can be claimed to exist between any three topics of each entailment mesh.

The relation of one topic T to another T' by an analogy can also be seen as: Being based on an isomorphism ${\displaystyle \Leftrightarrow }$, a semantic distinction ${\displaystyle /}$ between two individual universes on interpretation ${\displaystyle \mathbb {U} }$. Assuming an analogy holds for two topics in two distinct entailment meshes, then it should hold for all if the analogy is to be considered coherent and stable.

Cognitive Reflector

From conversation theory, Pask developed what he called a "Cognitive Reflector". This is a virtual machine for selecting and executing concepts or topics from an entailment mesh shared by at least a pair of participants. It features an external modelling facility on which agreement between, say, a teacher and pupil may be shown by reproducing public descriptions of behaviour. ^[2] We see this in essay and report writing or the "practicals" of science teaching.

Lp was Pask's protolanguage which produced operators like Ap which concurrently executes the concept, Con, of a Topic, T, to produce a Description, D. Thus:

Ap(Con(T)) => D(T), where => stands for produces.

A succinct account of these operators is presented in Pask ^[48] Amongst many insights he points out that three indexes are required for concurrent execution, two for parallel and one to designate a serial process. He subsumes this complexity by designating participants A, B, etc. ^[48] In Commentary toward the end of Pask, he states:

The form not the content of the theories (conversation theory and interactions of actors theory) return to and is congruent with the forms of physical theories; such as wave particle duality (the set theoretic unfoldment part of conversation theory is a radiation and its reception is the interpretation by the recipient of the descriptions so exchanged, and vice versa). The particle aspect is the recompilation by the listener of what a speaker is saying. Theories of many universes, one at least for each participant A and one to participant B- are bridged by analogy. As before this is the truth value of any interaction; the metaphor for which is culture itself. ^[48]

Learning strategies

In order to facilitate learning, Pask argued that subject matter should be represented in the form of structures which show what is to be learned. These structures exist in a variety of different levels depending upon the extent of the relationships displayed. The critical method of learning according to Conversation Theory is "teachback" in which one person teaches another what they have learned. ^[33]

Pask identified two different types of learning strategies: ^[33]

• Serialists – Progress through a structure in a sequential fashion
• Holists – Look for higher order relations

The ideal is the versatile learner who is neither vacuous holist "globe trotter" nor serialist who knows little of the context of his work.

In learning, the stage where one converges or evolves, many Cyberneticians describe the act of understanding as a closed-loop. Instead of simply “taking in” new information, one goes back to look at their understandings and pulls together information that was “triggered” and forms a new connection. This connection becomes tighter and one's understanding of a certain concept is solidified or “stable” (Pangaro, 2003). Furthermore, Gordon Pask emphasized that ^[49] conflict is the basis for the notion of “calling for'' additional information (Pangaro, 1992).

According to Entwistle, experiments which lead to the investigation of phenomenon later denoted by the term learning strategy came about through the implementation of a variety of learning tasks. ^[50] Initially, this was done through utilising either CASTE, INTUITION, or the Clobbits pseudo-taxonomy. ^{[51] [52] [53]} However, given issues resulting from either the time-consuming nature or operating experiments or inexactness of experimental conditions, new tests were created in the form of the Spy Ring History test and the Smuggler's test. The former test involved a participant having to learn the history of a fictitious spy ring (in other words, the history of a fictitious espionage network); the participant, having to learn about the history of five spies in three countries over the period of five years. The comprehension learning component of the test involved learning the similarities and differences between a set of networks; whereas the operation learning aspect of the test involved learning the role each spy played and what sequence of actions that spy played over a given year. ^[51]

While Entwistle noted difficulties regarding the length of such tests for groups of students who were engaged in the Spy Ring History test, the results of the test did seem to correspond with the type of learning strategies discussed. ^[54] However, it has been noted that while Pask and associates work on learning styles has been influential in both the development of conceptual tools and methodology, the Spy Ring History test and Smuggler's test may have been biased towards STEM students than humanities in its implementation, with Entwistle arguing that the "rote learning of formulae and definitions, together with a positive reaction to solving puzzles and problems of a logical nature, are characteristics more commonly found in science than arts student". ^{[55] [56]}

Applications

One potential application of conversation theory that has been studied and developed is as an alternative approach to common types of search engine Information retrieval algorithms. ^{[57] [58]} Unlike PageRank-like algorithms, which determine the priority of a search result based on how many hyperlinks on the web link to them, conversation theory has been used to apply a discursive approach to web search requests. ^{[57] [58]}

ThoughtShuffler is an attempt to build a search engine utilizing design principles from conversation theory: ^[59] In this approach, terms that are input into a search request yield search results relating to other terms that derive or help provide context to the meaning of the first in a way that mimics derivations of topics in an entailment structure. ^[57] For example, given the input of a search term, a neighbourhood of corresponding terms that comprise the meaning of the first term may be suggested for the user to explore. In doing this, the search engine interface highlights snippets of webpages corresponding to a neighbourhood terms that help provide meaning to the first. ^[57]

The aim of this design, is to provide just enough information for a user to become curious about a topic in order to induce the intention to explore other subtopics related to the main term input into the search engine. ^[60]
