This research note is concerned with the PUPS theory of cognition. PUPS was developed from the ACT theory in response to evidence about the importance of analogy to cognition. This report follows a general discussion of representation with a discussion of the analogy mechanism which drives the PUPS representation. A formal specification of the PUPS representation is next presented, and finally the connection between this representation and earlier propositional representations of the ACT theory is discussed.
