Question

Quizplus · Accepted Answer

Allport was one of the first psychologists to develop a comprehensive trait theory in the United States during the 1930s and 1940s. Although other psychologists, such as Cattell and Eysenck, also contributed to the development of trait theory, Allport is often considered the pioneer of the American approach. Zuckerman, on the other hand, is known for his research on sensation-seeking and personality, which is related but distinct from the trait theory.
