Which motivational theory by Clayton Alderfer compressed Maslow’s five need levels into three core categories: Existence, Relatedness, and Growth?

Explanation

• Alderfer’s ERG Theory classifies human needs into Existence (physiological/safety), Relatedness (social/esteem), and Growth (self-actualization).
• Unlike Maslow, ERG theory includes a ‘frustration-regression’ dimension, where failure to satisfy higher needs reactivates lower needs.
• ERG theory allows for multiple needs to operate simultaneously.
