According to Maslow's hierarchy of needs, people are unable to experience higher needs until the needs below them have been met. Considering this statement, if someone is unable to experience belongingness and love needs, what needs have not been met?

The answer is physiological and safety.

Explanation:

Maslow developed a hierarchy of needs divided in five different stages, often represented as a pyramid. The first two stages are:

Physiological needs, which involve any essential resource for living, such as water, food and housing; and Safety needs, which provide a sense of safety and well-being, such as employment, money and health.

Once these stages are satisfied, the person will look to satisfy love and belonging needs.
