Personality Psychology Introduction to Personality
Personality Defined • Personality is the set of • psychological traits and mechanisms • within the individual • that is organized and relatively enduring and • that influences his or her interactions with, and adaptations to, the environment.
Personality Defined • Personality is a • dynamic organization, • inside the person, • of psychophysical systems that create • the person's characteristic patterns of behavior, thoughts and feelings
Personality Defined This definition makes several points: Personality • has organization • is active, it has processes of some sort • is a psychological concept, but is tied to the physical body • is a causal force…it helps determine how the person relates to the world • shows up in patterns…it has consistency • is displayed in many ways (Carver, Scheier, Allport)
What is a Theory? Theory Defined • A theory is a model of reality that helps us to understand, explain, predict, and control that reality. • A theory is a set of related assumptions that allows scientists to use logical deductive reasoning to formulate testable hypotheses.
A Good Theory A useful theory must • Generate Research - both descriptive research and hypothesis testing, • Be Falsifiable; that is, research findings should be able to either support or refute the theory, • Organize Data into an intelligible framework and integrate new information into its structure; • Guide Action, or provide the practitioner with a road map for making day-to-day decisions; • Be Internally Consistent and have a set of operational definitions; and • Be Parsimonious, or as simple as possible.
Why Different Theories? • Psychologists and other scientists generate a variety of theories because they have different life experiences and different ways of looking at the same data. • Different theories may useful in different situations.
Major Questions a Personality Theory Attempts to Answer • Developmental-Historical Question • How did the person come to behave as he or she does now? What were the causes or the beginnings of the person? • Predictions-Consistency Question • Will this person behave similarly in similar situations at a later time? • Uniqueness-Generality Question • When are we unique and when are we the same? • Content/Process • "Personality is something that does something" Allport.
Pitfall of Theories • Ethnocentrism • Egocentrism • Dogmatism • Misunderstandings • Evidence (Lack of)
Basic Assumptions Concerning Human Nature • Heredity … Environment (?) • Free Will … Determinism (?) • Optimistic (Changeability) … Pessimistic (Unchangeability) (?) • Uniqueness …Universality • Physiological … Purposive Motivation • (Homeostasis … Heterostasis) • Unconsciousness … Conscious • Proactivity (Personal) … Reactivity (Situation) • Stage (Discontinuous) … Non Stage Theory (Continuous) • Early … Late Experience • Holism … Elementalism (Reductionism) • Cultural Determinism … Cultural Transcendence
Summary • Theories serve as a guide for researchers • Theories organize known findings • Theories allow us to make predictions • Theories are more than just beliefs • Theory and research are bound together
