" "An earlier paper (Pask, 1976) introduced conversational techniques, some involving a human participant in dialogue with a student, others involving a mechanically or computer implemented 'participant' through which the student 'talks to himself' under restrictions imposed by the device. In either case (human or mechanical monitoring) the subject matter of a conversation is represented in a liberally conceived, but standard, fashion, as a conversational domain consisting in an entailment structure (embodying one or more description schemes and indicating the many ways in which one topic may be known in terms of or derived from others) and behaviour graphs (one for each topic in the domain) that prescribe what may be done to model or explain the topic in question. Within this framework, the conversational techniques secure, or approximate, a standard condition for experiments on learning.
Andrew Gordon Speedie Pask (June 28, 1928 – March 29, 1996) was an English cybernetician and psychologist who made significant contributions to cybernetics, instructional psychology, experimental epistemology and educational technology.

Holists, either irredundant or redundant commit mistakes due to simple over-generalization (for example, that (β) always implies "Bushy Tail" which is true for only some subspecies) or systemic over-generalization to render the classification scheme more rational or symmetrical than it actually is (for example, falsely naming a subspecies "Bit QL" on the evidence that Q stands for "4-legged" and L stands for "Linear" together with the valid inference that a 4-legged linear creature exists. A serialst is prone to list the subspecies by examining picture cards in Class A. If he is to be successful, he checks the relevance of the information entering his list by forming single predicate hypotheses.
Observers are men, animals, or machines able to learn about their environment and impelled to reduce their uncertainty about the events which occur in it, by dint of learning... [We] shall examine human observers who, because we have an inside understanding of their observational process, belong to a special category. For the moment, we shall not bother with HOW an observer learns, but will concentrate upon WHAT he learns about, i.e. what becomes more certain.
We now come to the underpinning contention of the previous monograph. Psychological phenomena, especially those involved in learning and education, stem from or are related to states of consciousness. Using the argument which relates the information available about conscious processes to the type of experimental situation, we maintain that the basic unit of psychological /educational observation is a conversation. In order to test hypotheses and explicate the conversational transactions, it is necessary to invoke various tools and explanatory constructs. These are coherent enough to count when interlocked as a theory, and this theory was dubbed conversation theory.
