Titchener and structuralism 
Edward B. Titchener founded the theory of structuralism. Because he was a student of Wilhelm Wundt at the University of Leipzig, Titchener's ideas on how the mind worked were heavily influenced by Wundt's theory of voluntarism and his ideas of association and apperception (the passive and active combinations of elements of consciousness respectively). Titchener attempted to classify the structures of the mind, like chemists classify the elements of nature into the periodic table.
Titchener said that only observable events constituted science and that any speculation concerning unobservable events has no place in society (this view was similar to the one expressed by Ernst Mach). In his book, Systematic Psychology, Titchener wrote:
It is true, nevertheless, that observation is the single and proprietary method of science, and that experiment, regarded as scientific method, is nothing else than observation safeguarded and assisted.
Mind and consciousness 
Titchener believed that the goal of psychology was to study mind and consciousness. He defined consciousness as the sum total of mental experience at any given moment, and the mind as the accumulated experience of a lifetime. He believed that if the basic components of the mind could be defined and categorized and why they interact in the ways that they do (why) was the basis of reasoning that Titchener used in trying to find structure to the mind.
The state of consciousness which is to be the matter of psychology ... can become an object of immediate knowledge only by way of introspection or self-awareness.
and in his book An Outline of Psychology:
...within the sphere of psychology, introspection is the final and only court of appeal, that psychological evidence cannot be other than introspective evidence.
Unlike Wundt's method of introspection, Titchener had very strict guidelines for the reporting of an introspective analysis. The subject would be presented with an object, such as a pencil. The subject would then report the characteristics of that pencil (color, length, etc.). The subject would be instructed not to report the name of the object (pencil) because that did not describe the raw data of what the subject was experiencing. Titchener referred to this as stimulus error.
In his translation of Wundt's work, Titchener illustrates Wundt as a supporter of introspection as a method through which to observe consciousness. However, introspection only fits Wundt's theories if the term is taken to refer to psychophysical methods.
Elements of the mind 
Titchener's theory began with the question of what each element of the mind is. He concluded from his research that there were three types of mental elements constituting conscious experience: Sensations (elements of perceptions), Images (elements of ideas), and affections (elements of emotions). These elements could be broken down into their respective properties, which he determined were quality[disambiguation needed], intensity[disambiguation needed], duration, clearness[disambiguation needed], and extensity. Both sensations and images contained all of these qualities; however, affections were lacking in both clearness and extensity.
Interaction of elements 
The second issue in Titchener's theory of structuralism was the question of how the mental elements combined and interacted with each other to form conscious experience. His conclusions were largely based on ideas of associationism. In particular, Titchener focuses on the law of contiguity, which is the idea that the thought of something will tend to cause thoughts of things that are usually experienced along with it.
Titchener rejected Wundt's notions of apperception and creative synthesis (voluntary action), which were the basis of Wundt's voluntarism. Titchener argued that attention was simply a manifestation of the "clearness" property within sensation.
Physical and mental relationship 
Once Titchener identified the elements of mind and their interaction, his theory then asked the question of why the elements interact in the way they do. In particular, Titchener was interested in the relationship between the conscious experience and the physical processes. Titchener believed that physiological processes provide a continuous substratum that give psychological processes a continuity they otherwise would not have. Therefore, the nervous system does not cause conscious experience, but can be used to explain some characteristics of mental events.
Wundt and structuralism 
Wilhelm Wundt instructed Titchener, the founder of structuralism, at the University of Leipzig.The 'science of immediate experience' was stated by him. This simply means that the complex perceptions can be raised through basic sensory information. Wundt is often associated in past literature with structuralism and the use of similar introspective methods. However, this is not the case. Wundt makes a clear distinction between pure introspection, which is the relatively unstructured self-observation used by earlier philosophers, and experimental introspection. Wundt believes this type of introspection to be acceptable since it uses laboratory instruments to vary conditions and make results of internal perceptions more precise.
The reason for this confusion lies in the translation of Wundt's writings. When Titchener brought his theory to America, he also brought with him Wundt's work. Titchener translated these works for the American audience, and in so doing misinterpreted Wundt's meaning. He then used this translation to show that Wundt supported Titchener's own theories. In fact, Wundt's main theory was that of voluntarism.
Structuralism has faced a large amount of criticism, particularly from the behaviorist school of psychology. The main critique of structuralism was its focus on introspection as the method by which to gain an understanding of conscious experience. Critics argue that self-analysis was not feasible, since introspective students cannot appreciate the processes or mechanisms of their own mental processes. Introspection, therefore, yielded different results depending on who was using it and what they were seeking. Some critics also pointed out that introspective techniques actually resulted in retrospection – the memory of a sensation rather than the sensation itself.
Behaviorists fully rejected even the idea of the conscious experience as a worthy topic in psychology, since they believed that the subject matter of scientific psychology should be strictly operationalized in an objective and measurable way. Because the notion of a mind could not be objectively measured, it was not worth further inquiry. Structuralism also believes that the mind could be dissected into its individual parts, which then formed conscious experience. This also received criticism from the Gestalt school of psychology, which argues that the mind cannot be broken down into individual elements.
Besides theoretical attacks, structuralism was criticized for excluding and ignoring important developments happening outside of structuralism. For instance, structuralism did not concern itself with the study of animal behavior, abnormal behavior, and personality. In addition, structuralism denied adopting the theory of evolution into its theory, which is arguably its biggest downfall. Ironically, in a critique of functional psychology, Titchener writes in his Systematic Psychology:
[Functional psychology] was born of the enthusiasm of the post-Darwinian days, when evolution seemed to answer all the riddles of the universe; it has been nourished on analogies drawn from a loose and popular biology; it will pass as other fashions pass.
Titchener himself was criticized for not using his psychology to help answer practical problems. Instead, Titchener was interested in seeking pure knowledge that to him was more important than commonplace issues.
Contemporary structuralism 
Today, the theory of structuralism has become virtually extinct. While researchers are still working to offer objective experimental approaches to measuring conscious experience, in particular within the field of cognitive psychology, Titchener's form of introspection is no longer used. Today, any introspective methodologies are done under highly controlled situations and are understood to be subjective and retrospective. Proponents argue that psychology can still gain useful information from using introspection in this case.
