Final answer:
The highest level in Maslow's hierarchy is self-actualization, it represents the fulfillment of personal potential and is at the top of the psychological needs pyramid.
Step-by-step explanation:
The highest level in Maslow's hierarchy is self-actualization. Maslow's hierarchy of needs is a psychological framework that outlines human motivation which is often illustrated as a pyramid. At the base are physiological needs necessary for survival, such as food and shelter. These are followed by needs for safety, love and belonging, and esteem.
The pinnacle of the pyramid is self-actualization, a state where an individual has achieved their full potential. It represents growth of an individual toward fulfillment of the highest needs; those for meaning in life, in particular.
According to humanistic theories, self-actualization is an ongoing, life-long process and is only realized once all the other needs in the hierarchy have been met. Notably, some versions of the hierarchy include cognitive and aesthetic needs or self-transcendence above self-actualization.
