Final answer:
Self-actualization is the highest level of psychological development where a person achieves their full potential and experiences personal growth.
Step-by-step explanation:
The individual who is happy, autonomous, and creative has reached self-actualization, according to Abraham Maslow's hierarchy of needs. Self-actualization is the highest level of psychological development where a person achieves their full potential and experiences personal growth. It involves fulfilling one's inner potentials, expressing creativity, and pursuing meaningful life goals.
In Maslow's hierarchy, self-actualization is at the top tier, representing the ultimate level of psychological well-being. It can only be achieved once the lower needs on the pyramid, such as physiological needs, safety needs, belongingness and love needs, and esteem needs, have been satisfied.
For example, an individual who has met their basic needs and has developed a positive self-concept can focus on personal growth, explore their passions and interests, and engage in creative endeavors. They have a sense of purpose and fulfillment in life.
