An operational definition is designed to model or represent a concept or theoretical definition, also known as a construct.Scientists should describe the operations (procedures, actions, or processes) that define the concept with enough specificity such that other investigators can replicate their research.
Operationalization is the scientific practice of operational definition, where even the most basic concepts are defined through the operations by which we measure them. The practice originated in the field of physics with the philosophy of science book The Logic of Modern Physics (1927), by Percy Williams Bridgman, whose methodological position is called "operationalism".
The use of psychology in behavioral operations research links to the idea of judging the relationship between people's mental health and wellbeing and their behavior at work. Psychology experts often set up indicators to evaluate how an employee's surroundings, such as working environment and noise, can affect their productivity. [13]
Operational psychology is a specialty within the field of psychology that applies behavioral science principles through the use of consultation to enable key decision makers to more effectively understand, develop, target, and influence an individual, group or organization to accomplish tactical, operational, or strategic objectives within the ...
Pierre Janet was one of the first to use the concept in psychology. Mental operations have been investigated at a developmental level by Jean Piaget, and from a psychometric perspective by J. P. Guilford. There is also a cognitive approach to the subject, as well as a systems view of it.
The concrete operational stage is the third stage of Piaget's theory of cognitive development. This stage, which follows the preoperational stage, occurs between the ages of 7 and 11 (middle childhood and preadolescence ) years, [ 49 ] and is characterized by the appropriate use of logic.
At their operational altitude of 18,000 feet (5,500 m) and assuming clear channels, these aircraft can transmit radio and TV signals approximately 170 miles (270 km), which does not reach the objective areas near Baghdad. Straightforward physics dictate the range, given the power installed and the antenna configuration and assuming clear channels.
Operant conditioning originated with Edward Thorndike, whose law of effect theorised that behaviors arise as a result of consequences as satisfying or discomforting. In the 20th century, operant conditioning was studied by behavioral psychologists, who believed that much of mind and behaviour is explained through environmental conditioning.
