Final answer:
The correct answer is a) Humanistic; Behavioristic. Humanism aligns with existentialism through its focus on personal growth, while behaviorism is associated with the environmental determination of human actions.
Step-by-step explanation:
Existentialism is most strongly associated with the humanistic psychological viewpoint; as science is most associated with the behavioristic psychological viewpoint. The correct answer is a) Humanistic; Behavioristic. Humanism emerged as a movement focusing on personal control, intentionality, and the innate predisposition for "good" in human behavior, distinguishing itself from the reductionist views of behaviorism and the deterministic perspective of psychoanalysis. Whereas behaviorism, often associated with B. F. Skinner's work, suggests that the environment solely shapes human behavior through reinforcements and consequences.
The cognitive revolution challenged the behavioristic focus on external behavior by reintroducing the scientific focus on the mind, attention to the individual as a conscious being, and the study of cognitive processes. However, when addressing the correlation between existentialism and psychological perspectives, it is the existentialists' emphasis on human freedom and creating meaning that aligns more closely with humanistic psychology's focus on personal growth and self-actualization.
