Final answer:
The top of Maslow's hierarchy of needs is occupied by self-actualization needs, which pertain to achieving one's full potential after more basic physiological and psychological needs have been met.
Step-by-step explanation:
At the top of Maslow's hierarchy of needs, which is illustrated as a pyramid, are self-actualization needs. These represent the need to realize one's full potential and are the highest level Maslow identified. However, it is important to note that later in his life, Maslow proposed an additional level above self-actualization known as self-transcendence, which encompasses the motivation to strive for meaning beyond oneself, often through altruistic or spiritual goals. The fundamental concept is that before one can focus on self-actualization, basic physiological and psychological needs at the lower levels of the hierarchy must be met, which include needs such as food, safety, love, and esteem.
