When studying Personality Theory as a discipline, as well as other fields in psychology, it is important to understand why it is a discipline. Well known theorists have attempted to view and understand human life though a certain lens in order to explore the many convolutions of an individual’s personality, and wonder and ask questions about human nature and personality. It is through this exploration that the discipline has evolved as a science since Freudian times.

The hypothesis is a suggested explanation or preliminary idea of how something works, many call it an educated guess or possible explanation for something, which should be able to be tested and needs to be able to be proven false if necessary. This is a cyclical process, where more hypotheses can be added and determined as the theory develops (p. 8). A theory must be able to generate research, be able to be organized or categorized as well have the ability to give a platform or structure to ‘guide actions’, like using the ‘if this then, what?’ notion (Jameson, PPT). For example, in order to find a workable answer a psychologist could ask: if the patient suffers from low self-esteem and melancholy, then …show more content…

Reliability is determined when the instrument yields consistent results and validity is the ‘degree to which the instrument/experiment design measures what it is supposed to measure’ (Jameson,
