Which psychologist is known for the theory of dualism?

• A. Perry
• B. Piaget
• C. Sullivan
• D. Watson

Answer: (A)

The psychologist known for the theory of dualism is actually not Perry. Dualism, particularly in psychological and philosophical contexts, is often associated with René Descartes, who famously proposed the distinction between the mind and body as separate entities. This concept suggests that mental phenomena are non-physical and that the mind and body interact but are fundamentally different in substance.

Perry, while known for his work in developmental psychology related to the cognitive development of college students and the understanding of epistemological development, does not specifically address dualism in his theories.

In contrast, Piaget focused on cognitive development in children, emphasizing the stages of intellectual growth rather than a dualistic approach to understanding the mind and body. Sullivan contributed to interpersonal theory and the dynamics of personality but did not center his work around the concept of dualism. Watson, a prominent figure in behaviorism, rejected mentalistic concepts entirely and focused on observable behavior, leaving little room for dualistic interpretations.

Thus, while Perry may be a viable candidate for some psychological theories, he is not specifically recognized for dualism.
