Final answer:
A psychologist who studies creative individuals maximizing their talents is likely a proponent of humanistic psychology, which focuses on personal growth and self-actualization.
Step-by-step explanation:
A psychologist who focuses on healthy, creative people who fully utilize their talents is most likely an advocate of humanistic psychology. This field of psychology, often referred to as the 'third force', is a response to both the deterministic perspectives of psychoanalytic theory and the environmental focus of behaviorism.
Humanistic psychology emphasizes the innate capacity for self-determination and growth within healthy individuals. Abraham Maslow, a pioneer of humanism, studied exemplary figures and concluded that self-actualized individuals share traits like openness, creativity, and compassion—hallmarks of this psychological approach.
The highest need in Maslow's hierarchy of needs is self-actualization, the achievement of one's fullest potential, reflecting humanism's emphasis on personal growth and self-directed change.
