  • Describing Applied Cognitive Science
  • Chronicle the history, development and main contributors to the discipline
  • Describe how other fields and world events have influenced its development
  • Describe some of the methodologies used in the field

Cognitive Psychology

  • Study of the mental operations that support people's acquisition and use of knowledge

  • Early cognitive psychologists focused on methodology, basic cognitive processes (pure research) and theory building

Applied Cognitive Psychology

  • A fairly young field
  • It relies on methods, findings, and theories from cognitive science
  • Aims to understand cognitive processes as they occur in the real world of human experience
  • Attempts to solve practical/real-life problems

Wilhelm Wundt (1874)

  • Father of experimental psychology

  • Also measured reaction times to simple and two-choice stimuli
  • His work showed that psychology could be a valid experimental science

Galton (1883)

  • Investigated mental imagery
  • Used a questionnaire to investigate the strength and nature of mental imagery
  • Inquired about illumination, definition, and coloring of mental images

Thorndike (1914)

  • Developed learning theory (laws of learning)
  • Introduced operant conditioning and the learning curve

Ebbinghaus (1885)

  • Studied memory of nonsense syllables
  • Frequent repetitions help to fix mental associations more firmly in memory
  • Distributing learning trials over time is more effective than massing practice into a single session
  • Continued practice after the learning criterion has been reached enhances retention

Bartlett (1932)

  • Argued that cognitive research should have relevance to the real world
  • Advocated for naturalistic experimental designs and test materials that bear some semblance to real-life situations, such as meaningful information versus nonsense syllables
  • His research on memory for stories and pictures had direct real-life applications, such as on the testimony of courtroom witnesses

Donald Broadbent (1958)

  • Studied selective auditory attention
  • His dichotic listening experiments demonstrated the limitations of human attention

Alan Turing

  • His Colossus computer helped break the German "Enigma" codes during WWII
  • Drew an analogy between computers and human minds (hardware: brain, software: mind)
  • Theorized that thinking could be described in terms of algorithmic manipulation of information
  • These ideas led to the information processing paradigm in psychology, cognitive psychology and artificial intelligence

Other Influences

  • World wars
  • Impacted human-machine interaction
  • Influenced the visual and auditory displays, control tools, and systems that enable efficient human-machine interaction
  • Human factors psychology

  • Integrate mentalistic concepts to explain behavioral data

The Cognitive Revolution vs. Behaviorism

  • According Behavioral Psychologists the Goal is to study observable behaviour
  • Hypotheses about internals thoughts and ways of thinking are not based in observed reality
  • Animal experiments, conditioning, experiments

Potential Problems With Behavioralism

  • Much of human experience is unobservable - decisions or memories
  • Behaviourism cant account for learning and adapting
  • Evidence needed for responding, and learning without reinforcement
