Differences from Maslow's Hierarchy

In addition to the reduction in the number of levels, the ERG theory differs from Maslow's in the following three ways:

• Unlike Maslow's hierarchy, the ERG theory allows for different levels of needs to be pursued simultaneously.
• The ERG theory allows the order of the needs be different for different people.
• The ERG theory acknowledges that if a higher level need remains unfulfilled, the person may regress to lower level needs that appear easier to satisfy. This is known as the frustration-regression principle.

Thus, while the ERG theory presents a model of progressive needs, the hierarchical aspect is not rigid. This flexibility allows the ERG theory to account for a wider range of observed behaviors. For example, it can explain the "starving artist" who may place growth needs above existence ones.
