Historical Perspective
Originating in the early 20th century, the idea of operational definitions is linked to the development of behaviorism and logical positivism. Behaviorists such as B.F.

A group of scientists and philosophers known as the logical positivists made the claim that a claim must be testable by empirical evidence in order to have any real validity. As a result, t...
Current State of Research
Today, operational definitions are still a key component of psychological research. They aid in the replicationof research, ensuring that other researchers may conduct similar experiments to confirm the results. They also aid in making abstract ideas more understandable, measurable, and observable.
Importance
For a number of reasons, operational definitions are important. By giving accurate and detailed definitions of variables, they aid in ensuring the validity and reliabilityof a study. They enable the measurement and testing of abstract ideas. They also make it possible for researchers to replicate findings, which is essential to scientific inquiry. In essence, operational definitions help psychological research to be transparent and objective.
