Motivation Theory of Maslow is called ________.

Concept: Maslow proposed that human motivation can largely be explained through a hierarchy of needs -- physiological, safety, love/belonging, esteem, and self-actualization -- with behavior generally driven toward satisfying the most pressing unmet need in that order (though several needs can motivate a person at once). Because the framework is built around identifying and satisfying these "needs," it is known as the Need Hierarchy (Need) Theory of motivation.

Application: In this item, "Principle of Need" is the term that matches this idea -- Maslow's theory explains motivation through a hierarchy of NEEDS, not through physical drives, willpower, or a single motivational force.

Cross-check (contrast the distractors by value):

• Physical Principle: would restrict motivation to bodily/physiological states alone, but Maslow's hierarchy spans far beyond the physical to social and psychological needs (belonging, esteem, self-actualization).

• Strong Will Power Principle: ties motivation to conscious willpower/determination, a concept from volition research, not from Maslow's need-based model.

• Principle of Drive: refers to physiological drive-reduction models (e.g., Hull's Drive Theory), a separate motivational framework built on tension-reduction, not on a hierarchy of needs.

Result: Motivation Theory of Maslow is therefore called the Principle (Theory) of Need.
