Mechanical Cognition Sciences

An approach to studying the mind that models cognitive processes as sequences of discrete, rule-governed operations on symbolic representations. This is the classic "computer metaphor" of cognition: perception inputs data, working memory buffers it, a central processor applies logical rules, and output is produced. It treats thinking as computation, and the brain as the hardware running the software. This paradigm powered the cognitive revolution and remains indispensable for many applications, though its limitations are increasingly apparent.

Mechanical Cognition Sciences Example: Early expert systems in artificial intelligence were pure Mechanical Cognition. Programmers interviewed human experts, extracted their decision rules (IF symptom A AND test B THEN diagnosis C), and encoded them in software. The system "thought" by mechanically applying these rules. This worked for well-defined domains like mineral prospecting but failed spectacularly for common sense, metaphor, or any task requiring flexibility. The rules were too rigid; the world refused to stay within their IF-THEN boundaries.
