Titchener, E. B. (1898). The postulates of a structural psychology. The Philosophical Review, 7(5), 449–465.
The purpose of this study was for experimental psychologists to use the same principles of division through out the process, as it remains a representation of modern psychology as the exact counterpart that is parallel to modern biology. Other determines factors that ware of importance were the scope and the divisions of psychological science in consistence with the nature and number of structural elements that consist in the mind. It was determined that Biology, which is the science of living things, is made up of three mutually interdependent sciences which are morphology, physiology and ontogeny that required the necessary classification their divisions as the counterpart is distinguished. Titchener mentioned very early in this article of the three points of view on how to conduct these experiments which are that “we may enquire into the structure of an organism, without regard to function, -by analysis determining its component parts, and by synthesis exhibiting the mode of its formation from the parts. Or we may enquire into the function of the various structures which our analysis has revealed, and into the manner of their interrelation as functional organs. Or again, we may enquire into the changes of form and function that accompany the persistence of the organism in time, the phenomena of growth and of decay” (Titchener, 1898). It became apparent that his main focus was to discover the elements that are in the mind, their quantity, but not for the reason of their existence. The goal is to distinguish the structure of psychology or structural psychology, the function or the descriptive details of functional psychology, ontogenetic psychology, taxonomic psychology, social psychology and phylogenetic psychology with the useful help of biological considerations. The first discovery was that a
