Alderfer's ERG theory focuses on which three types of needs?

Alderfer's ERG theory categorizes human needs into three distinct groups: existence needs, relatedness needs, and growth needs.

Existence needs encompass all of the material and physiological desires necessary for survival, such as basic food, shelter, and safety requirements. Relatedness needs address the social aspects of human life, focusing on the need for interpersonal relationships and a sense of belonging. Growth needs pertain to the intrinsic desire for personal development and self-improvement, encouraging individuals to pursue their potential.

This framework provides a more flexible approach compared to Maslow's hierarchy of needs, allowing for the idea that individuals can simultaneously pursue needs across different categories rather than strictly following a linear progression. By recognizing that growth can be pursued alongside fulfilling basic social and physical needs, Alderfer's theory helps to explain the complexity of human motivation in a more comprehensive way.

In contrast, the other options mentioned do not accurately represent Alderfer's framework, focusing instead on different sets or classifications of needs that do not align with ERG theory.
