Edward Titchener (1867-1927) was a British psychologist who established the school of structuralism and coined the word empathy (which is the ability to put oneself in another's shoes). Structuralism proposed that by defining, categorizing, and organizing aspects of the mind then mental processes could be understood. There was no interest in the unconscious or the subconscious mental processes - only the conscious mind was considered to be a viable subject of study.
Importance on introspection was also a focus within structuralism. Research participants were trained in identifying mental processes and presented with stimuli. They then used introspection to describe the sequence of mental processes. Titchener theorized there were three facets that comprised conscious experiences: images, sensations, and feelings.
