What theory suggests that needs develop during early life experiences?

The theory that suggests needs develop during early life experiences is McClelland's Acquired Needs Theory. This theory posits that individuals acquire certain needs based on their experiences and interactions throughout their lives. It identifies three primary needs that motivate behavior: the need for achievement, the need for affiliation, and the need for power. These needs are shaped by personal experiences, particularly during formative years, as individuals learn what is important to them and how they relate to others.

In contrast, Maslow's Hierarchy of Needs focuses on a tiered model of human motivation, positing that individuals are motivated to satisfy basic needs before progressing to higher-level psychological and self-fulfillment needs. Alderfer's ERG Theory allows for more flexibility in need fulfillment but does not specifically emphasize early life experiences as a foundational aspect. Herzberg's Two-Factor Theory distinguishes between hygiene factors and motivational factors but also does not delve into the developmental aspects related to early experiences.
