What is the key difference of the Alderfer's ERG theory in relation to need satisfaction?

Alderfer's ERG theory is an important advancement over Maslow's hierarchy of needs, primarily because it emphasizes the idea of frustration-regression. This concept suggests that if an individual is unable to satisfy higher-level needs (such as esteem or self-actualization), they may regress to lower-level needs (like existence or relatedness) to find satisfaction.

For example, if someone is striving for personal growth but encounters barriers, they might shift their focus and invest more time and effort into nurturing their relationships or ensuring their basic existence needs are met. This flexibility in addressing needs reflects a more dynamic understanding of human motivation, allowing for movement both upwards and downwards in the hierarchy of needs, contrary to the more rigid sequential approach found in Maslow's original theory.

The other options do not correctly highlight this core aspect of Alderfer's theory, which centers on the interaction and possible movement among different levels of needs rather than adhering to a strict pattern or excluding certain needs. This makes frustration-regression a vital component of understanding how individuals prioritize and address their motivational needs over time.
