PSYC85H3 Lecture Notes - Lecture 11: Turing Machine, Cognitive Psychology, Unconscious Mind
Document Summary
Primary stimulus for growth of cognitive psychology came from outside academic psychology: developments in logic, mathematics, computer science themselves products of applied research during wwii. How to use transmit the most possible information that"s in encoded through a limited channel so that you don"t lose bits of it. Norbert wiener (1894-1964: designed servomechanisms, they are goal-oriented & self-regulate based on feedback from target, like a torpedo (mechanical model) A mechanical model for immediate memory & attention. Stm (short term memory) limits how many are active: humans attend to stimuli. Differing depths of processing (how much of the information do you recognize and how do you use it: all this shows that humans have active attention. Symbolic logic equated with electronic circuitry & neural networks: electronic circuits and it"s on-off positions are like neurons that fire or don"t. Turing machine (kind of like a calculator) performs set of stored instructions.
