"A Latin term meaning 'the faculty of knowing.' A set of processes (cognitive functions) that perceive and process stimuli from outside and in; store and retrieve information; decide upon and execute actions to achieve goals."

Historical Development of Studying Cognition

Natural Philosophy and Early Psychology

Natural Philosophy and Early Psychology

Early physicians and psychologists who built models of mental processes through behavioral observation and experimental manipulation, using methods like psychophysical judgment and memorization for later testing to quantify cognitive processes.

Key figures:

Example: George Miller's "magic number 7 plus or minus 2" experiment on working memory capacity—demonstrates how behavioral testing can reveal cognitive limitations.

Many methods from this era are still used today, such as verbal working memory span tests.


Behaviorism (Early 20th Century)

Behaviorism

"A school of psychology that focused on highly controlled experiments that match objective external stimuli to measurable behavior. Behaviorism rejects subjective work on mental functions as being outside the domain of proper scientific inquiry."
