[edit] History
PARRY was written in 1972 by psychiatrist Kenneth Colby, then at Stanford University.[1] While ELIZA was a tongue-in-cheek simulation of a Rogerian therapist, PARRY attempted to simulate a paranoid schizophrenic.[1] The program implemented a crude model of the behavior of a paranoid schizophrenic based on concepts, conceptualizations, and beliefs (judgements about conceptualizations: accept, reject, neutral). It also embodied a conversational strategy, and as such was a much more serious and advanced program than ELIZA.
PARRY and ELIZA (also known as "the Doctor"[2][3]) "met" several times.[1]RFC 439[2] The most famous of these exchanges occurred at the ICCC 1972, where PARRY and ELIZA were hooked up over ARPANET and "talked" to each other[2].
