Introduction to Personality Personality = an individual’s characteristic patterns of thoughts, emotion, and behavior Plus the psychological mechanisms (hidden or not) behind those patterns Plus the psychological mechanisms (hidden or not) behind those patterns

Pet Activity Think of pet you have had or have known. Describe their personality. Write this down.

Pet Personality How did you describe your pet? (what types of words?) How did you describe your pet? (what types of words?) Would everyone agree with your description? (would other people describe your pet the same way?) Would everyone agree with your description? (would other people describe your pet the same way?) How do you know about your pet’s personality? (i.e. on what did you base your descriptions?) How do you know about your pet’s personality? (i.e. on what did you base your descriptions?) Why is your pet the way he/she/it is? Why is your pet the way he/she/it is?

Questions asked parallel those in personality psychology What are the basic pieces of people? What are the basic pieces of people? How do we learn about people’s personality?

Goal of personality psychology Explain whole people Explain whole people In this mission, idea is to combine subfields of psychology into an integrated whole In this mission, idea is to combine subfields of psychology into an integrated whole Mission impossible – very difficult to look at everything at once and still maintain a scientific approach Mission impossible – very difficult to look at everything at once and still maintain a scientific approach

Mission Impossible/Need to focus efforts Personality psychologists must focus their efforts: 1. Trait approach = how people differ psychologically from one another. Focus on personality traits. 2. Psychoanalytic approach = focus on unconscious mind and internal conflict 3. Biological = address physiology, inheritance, and evolution and relate these to personality

Basic Perspectives on Personality continued 4. Humanistic/phenomenological approach = focus on conscious experience, focus on growth, spirituality, and self-fulfillment 5. Behaviorist/learning – focus on science of learning, impact of rewards, punishment 6. Cognitive approach – emphasizes human thought, draws from modern cognitive psychology 7. Interactionist perspective – emphasizes that we are different in different situations; situation and person interact

Focus – What each perspective does best Approaches often complement each other rather than compete Approaches often complement each other rather than compete Toaster analogy: a device that does one thing well is unlikely to do other things well Toaster analogy: a device that does one thing well is unlikely to do other things well

Themes and Issues 1. Awareness/unconscious 2. Concept of self 3. Unique vs. general laws Nomothetic Nomothetic idiographic idiographic 4. Person vs. situation 5. Philosophical view of people 6. Past, present, future 7. Feelings, thoughts, behavior

Approaches to theory building Two levels of information that personality theorists are interested in: 1. Individual level – what are individual people like? What are (this person’s) characteristics? 2. General level – general laws that apply to all people

Approaches to theory building Deductive approach – works from the “top” down generate basic laws about people generate basic laws about people Make deductions about what individual people will be like based on those laws Make deductions about what individual people will be like based on those laws Example: Freud – developed theory first Example: Freud – developed theory first

Approaches to theory building Inductive approach – reasoning based on a “bottom-up” approach. Collect data about people first Collect data about people first Develop the theory based on the data Develop the theory based on the data Example: Five Factor trait model Example: Five Factor trait model

Approaches to theory building Borrow and learn from related disciplines Use concepts that are known in other fields and apply to personality psychology Use concepts that are known in other fields and apply to personality psychology Example: PET scans allow us to learn about brain function and structure. Pers. theory must be consistent with this. Example: PET scans allow us to learn about brain function and structure. Pers. theory must be consistent with this.

Approaches to theory building Most modern theories involve all of these approaches. Best theories meet scientific criteria for a theory: 1. Comprehensive 2. Parsimonious 3. Testable 4. Productive – leads to new ideas & research
