How does the Alderfer’s ERG theory differ from Maslow’s hierarchy of needs theory?

ANSWER

Maslow’s theory classifies human needs as lower-order needs and higher-order needs. It states that a satisfied need is not a motivator of behavior. It states that five needs exist in a hierarchy and that a need does not become activated until the next-lower-level need is already satisfied. People are expected to advance step by step up the hierarchy in their attempt to satisfy the lowest-level need that is currently unfulfilled.

In contrast, Alderfer’s ERG theory groups human needs into three categories. This theory suggests that any or all needs can influence individual behavior at a given time. ERG theory does not assume that certain needs must be satisfied before other needs become activated. Alderfer also believes that satisfied needs do not lose their motivational impact and that they can become reactivated and influence behavior when a higher-level need cannot be satisfied.
