- self report
- Rorschach ink blot test
- TAT

- reveal more about life than direct questioning of fear
- ie Rorschach anD TAT
Rorschach ink blot test
- person interprets ink blot
- reveal inner feelings
- interpret personality structure
Thematic apperception test (TAT)
- create stories about pictures of ambiguous people
- reveal underlying motives
Controversy with projective tests
- are they reliable?
- examiner add interpretation
Motivation
- traits reflect motives
- ie hunger motive, go to snack bar
- issue projective tests
Search for core traits
- traits classified using adjectives-organized in heirarchal power
- factor analysis
- big 5
Factor analysis
Sort traits items into small dimensions
- based on how people use traits to rate themselves
- detect similarities and differences
Big 5 dimensions of personality; 5 factor model
CANOE

- variation in alertness (ie extroverts seek out social interaction, introverts avoid)
- over/under stimulation of reticular formation
Grays theory for extroversion/intraversion an neuroticism
- 2 brain systems are responsible for extraversion and neuroticism
- behavioral activation system: go system seeking social reinforcement

Memory suppression-brain activity
Decreased hippocampal activity
