What is meant by the frustration-regression principle in Alderfer's ERG Theory?

The frustration-regression principle in Alderfer's ERG Theory highlights the idea that when individuals face obstacles in fulfilling higher-level needs, they may regress to focusing on lower-level needs instead. For instance, if a person strives for esteem or self-actualization but encounters challenges that prevent them from achieving these needs, they might shift their attention back to fulfilling basic or related needs, such as those for safety or belonging. This is important because it illustrates the non-linear nature of human motivation; individuals do not always progress smoothly from one level of need to another. Instead, experiences of frustration can lead to a retreat to previously satisfied lower-level needs. This principle underscores the importance of recognizing that motivation is dynamic and may involve both advancement and regression based on circumstances.
