Strictly speaking, there is room for the view that, while psychologism is not intrinsically hostile to logic, psychologism about the unconscious and the pre-linguistic simply stretches logic further than it can go, and should therefore be resisted. Most, if not all, of what people don’t like about so liberal a conception of logic is already present in the standard objections to psychologism, which we have already discussed. If there is anything odd about our approach, it can only be the proposal to include such matters in the ambit of logic. There is a large literature - if not a large consensus - on various aspects of subconscious, pre-linguistic cognition. Some people will simply abhor the idea, needless to say. In the past pages we have flirted with the idea that a PLCS might extend or have an adaptable component that extends to cognitive processes that are pre-linguistic and subconscious. Gabbay, John Woods, in A Practical Logic of Cognitive Systems, 2003 3.2.6 Logics for Down Below These and other properties make production systems well suited to the modeling of cognitive performance and cognitive skill.ĭov M. If relevant information appears in the data memory, the production system can abandon its current line of processing and follow a new one. For the same reason, it is interruptible. Because the processing at each step is determined by what the rule conditions ‘recognize’ in the data memory, the control can be very flexible. A production system is not forced to follow a fixed control structure, such as a rigid hierarchy of routines and subroutines.

Each rule can be written to be self-contained, expressing an item of knowledge which the problem solver is postulated to know.

Each rule in a production system is potentially independent of all the other rules. In the act phase, a single rule is chosen for firing, so the actions are carried out one at a time. The recognize phase, i.e., the testing of conditions, occurs in parallel, across possibly hundreds of thousands of rules.

Production systems exhibit aspects of both parallel and serial processing, corresponding to the two phases of the recognize–act cycle.
