Answer:
Freudian and humanistic theorists sought to explain personality; trait theorists sought to describe personality.
Explanation:
Freudian theorists have a perspective based on the work of Sigmund Freud, the founder of psychoanalysis. To Freud, our mind was composed of three elements: the id, the ego, and the superego.
Humanistic theorists work from the perspective that dysfunction should not be the focus of study. Instead, they seek to help people thrive by developing to their full potential. Both the humanistic and the Freudian approaches seek to explain behavior.
Trait theorists, on the other hand, do not seek the same thing. Their purpose is to describe behavior by measuring traits that compose people's personalities. Traits can be explained as being habitual patterns of emotion, behavior, and thought.
