  2. Sept. 11, 2014 Chapter 1.3 - Introduction • Outline • The birth of cognitive psychology • Contributions from other fields • • Communications • • Human engineering • • Computer Science • • Linguistics • The Hixon symposium • Sept. 11, 1956 • • The 1960s • Assumptions of cognitive psychology Study Question. • What were the contributions of non-psychological fields of study to the development of cognitive psychology?

  4. History of Cognitive Psychology • The Birth of Cognitive Psychology • WW II • Human engineering • Brain-damaged soldiers • Advances in Communications • Information theory and the human information processor • Development of servo-mechanical devices • Tackling teleology (purposeful behaviour) • The development of the computer • AI / Simulations • Analogy

  5. History of Cognitive Psychology • The Birth of Cognitive Psychology • WW II and Human Engineering • Limits of the behaviourist approach • Problems of perception, judgment, decision making, problem solving • Fitts and Jones (1947) • 50% of pilot errors in operating aircraft controls involved using the wrong control devices • Aircraft Position of Control • Left Centre Right • B-25 throttle prop mixture • C-47 prop throttle mixture • C-82 mixture throttle prop • Mappings between locations and functions needed to be consistent and unambiguous. • WW2: in first 2 years of combat, over 2,000 multi-engine U.S. aircraft crashed because the landing gear and wing flap controls could not be discriminated from one another by location, feel, or direction of movement. • • Design error, not "pilot" error.

  6. History of Cognitive Psychology • The Birth of Cognitive Psychology • WW II and Human Engineering • “Human / machine system” concept • Humans as receivers, processors, and transmitters of information. • From human engineering, cognitive psychology has retained: • Humans as information processors • Processing limits • Government interest in funding (e.g., NASA)

  7. History of Cognitive Psychology Claude Elwood Shannon (1916 - 2001) • The Birth of Cognitive Psychology • Advances in Communications Engineering • Information theory and human information channels • Contributions of Claude Shannon • Father of information theory • A Symbolic Analysis of Relay and Switching Circuits (1938) • “The most important masters thesis of the Century” (Gardner, 1985) • Laid the groundwork for the Boolean basis of computers • Introduced the concept of a bit • What is information? • > Information reduces uncertainty • > One bit reduces uncertain by 1/2

  8. History of Cognitive Psychology Claude Elwood Shannon (1916 - 2001) • The Birth of Cognitive Psychology • Advances in Communications Engineering • Contributions of Claude Shannon • E.g., Locating a space on a checker board • 0 = up, 1 = down; 0 = left, 1 = right; up/down, left/right, etc. 1 1 0 1 0 0

  9. History of Cognitive Psychology • The Birth of Cognitive Psychology • From communications engineering, cognitive psychology retained: • Coding • Limited channel capacity • Serial and parallel transmission / processing

  10. History of Cognitive Psychology • The Birth of Cognitive Psychology • The Hixon Symposium (Sept. 1948) • “Cerebral Mechanisms in Behaviour” • John von Neumann • Compared the newly developed electronic computer to the brain • Warren McCulloch • “Why the Mind is in the Head” • - Compared the nervous system to “logical circuits” • Karl Lashley • “The Problem of Serial Order in Behaviour”

  11. History of Cognitive Psychology George Miller (1920 - ) • The Birth of Cognitive Psychology • Miller’s recollections • Cognitive science as a counter-revolution • Birthdate of Cognitive Science: Sept. 11, 1956 • Key events in 1956: • • Bruner, Goodenough, & Austin publish “A Study of Thinking” • • Tanner & Swets apply signal detection theory to perception • • Miller’s “magical number” paper is published • • Carol publishes a volume of Whorf’s works on the effects of language on thought • • Sept 11: Symposium at M.I.T. by the “Special Interest Group in Information theory” • - Newell & Simon with a “logic machine” • - Rochester used a computer to test Hebb’s cell assemblies theory • - Chomsky laid the foundations for “Syntactic Stuctures” • - Other papers discussed the speed of perceptual processes and SDT.

  12. History of Cognitive Psychology • Cognitive Psychology - A child of the 1960s • Key events in 1960 • The “revolution” revisited • Harvard Center for Cognitive Studies (Miller/Bruner; 1960) • Sternberg’s dissertation (1960) • Miller, et al. (1960). Plans and the structure of behaviour • Fodor & Katz’s (1964) The Structure of Language • Neisser’s (1967) Cognitive Psychology textbook.

  13. History of Cognitive Psychology • The Assumptions of Cognitive Psychology • Mental processes exist. • Mental processes can be studied scientifically. • We are active information processors. • Miller’s Informavores • The brain does it.
