Which term did Wundt use to describe his theoretical approach to sensations?

Wundt used the term "Structuralism" to describe his theoretical approach to sensations. This approach emphasizes breaking down mental processes into their most basic components, which aligns with Wundt's focus on understanding the structure of the mind through introspection and experimentation. By studying the elements of consciousness—such as sensations, feelings, and images—Wundt aimed to establish a systematic and scientific basis for psychology. This foundational perspective was pivotal in moving psychology towards a more empirical and scientific discipline, paving the way for future research and theories in cognitive psychology.

The other terms represent different psychological approaches: Functionalism focuses on the function of mental processes and behavior; Behaviorism emphasizes observable behavior rather than internal mental states; Gestalt psychology studies perception and emphasizes that the whole is greater than the sum of its parts. Each of these perspectives developed in response to or in contrast with the ideas proposed by Wundt and Structuralism.
