Definition

A theoretical approach in psychology that focuses exclusively on observable actions and measurable external responses, rather than internal thoughts or feelings.

Etymology

Derived from the word 'behavior' with the suffix '-ism', indicating a doctrine or system. It emerged in the early 20th century as a school of thought that sought to establish psychology as an objective science by rejecting the study of consciousness.
