E.B. Titchener (1867-1927) defined ‘Psychology’ as the science of____________?

The correct answer is Science of Experience. E.B. Titchener (1867–1927) formally defined psychology as the science of experience to distinguish it from other sciences and to establish its domain as the study of conscious processes as they are experienced by the individual.

Context & Definition

• Founder of Structuralism: Titchener founded Structuralism, which was the first formal school of psychology in the United States. He believed that the primary goal of psychology was to discover the basic "atoms" of the mind.
• The Definition in Detail: He argued that psychology should study the structure of the human mind by analyzing the basic elements of immediate, conscious experience. For Titchener, psychology was not about the physical world itself, but about the experience of that world. He famously asserted that physics studies experience independent of the perceiver (e.g., a chair as a physical object), whereas psychology studies experience as it is dependent on the experiencing person (e.g., the perception and sensation of the chair).
• The Method – Introspection: To study this structure, he employed introspection—a rigorous, trained method of self‑observation. Trained participants would report their conscious experiences (breaking them down into sensations, images, and feelings) in response to controlled stimuli, allowing Titchener to map the basic elements of consciousness.

Why the Other Options Are Incorrect

• Science of Soul (Option 1): This definition belongs to ancient and medieval philosophy (e.g., Plato, Aristotle, and early religious scholars). Titchener explicitly rejected metaphysical concepts like the "soul," insisting that psychology must be an empirical, natural science grounded in observable experience.
• Science of Mind (Option 2): While this is a common, general definition of psychology (used by figures like William James), it is too broad for Titchener’s strict operationalism. He specifically narrowed the focus to experience to avoid mentalistic speculation that could not be directly observed or experimentally measured.
• Conscious Experience (Option 4): This phrase accurately describes the subject matter that Titchener investigated (since he focused on the conscious mind). However, his formal, explicit definition of psychology as a science was "Science of Experience." He used this precise wording to differentiate his structuralist program from physics and biology. While "Conscious Experience" is closely related, the exact textbook answer to this specific MCQ is "Science of Experience."

In summary: Titchener redefined psychology to make it an experimental science of the conscious mind, breaking it down via introspection. His official definition—Science of Experience—remains the definitive answer to this question, clearly separating psychology from philosophy and the physical sciences.
