What are state differences?
temporary differences in people’s psychology . These differences are fundamentally temporary
What are trait differences?
Semi-Permanent, enduring differences between people’s psychology

Shyness, friendliness, courage
What is the definition of Personality?
A person’s characteristic and enduring style of behaving, thinking, and feeling. (i.e traits, not states)
What is the first problem in trying to identify how many distinct personality traits there are?
If you conclude too many, the ability to generate predictions and test them becomes near-impossible. If the number was too high we could never have a scientific theory. It would be way too difficult
What is the second problem in trying to identify how many distinct personality traits there are?
If you make too few, prediction is trivial but your theory has not explained anything at all about how people are actually different.
What are the two measures we would use for personality?
Self-report and Observation
What is the problem with self report?
- People may not tell you how they actually act but instead tell you how they wish they acted. (people aren’t always truthful)
What is the problem with Observation?
- researcher may not be able to reliably infer the causes of behaviour because of their biases.
- If people know they are being observed, they may not act naturally.
What are the 4 approaches to discovering where distinct personalities come from?
- Heredity and Evolution
- Early developmental Experiences
- Socio-Cognitive approach
- Humanistic Approach
What is the perspective on the role of heredity and evolution on personality?
The theory is that personality is a genetic trait that allows for variable adaptations to changing environments. They believe that we need balances/ different personalities in order to have people act differently and be adaptable to different environments.
What is the perspective on the role of Early Developmental experiences on personality? What approach is this most associated with?
theory is that personality comes from positive and negative experiences we have in our childhood and youth (most associated w/ Psychodynamic approach of Sigmund Freud).
What is the social-cognitive approach on personality? Do they believe that personality is permanent?
theory is that personality comes about from our history of reward and punishment in various social situations. They believe that personality is not permanent and that it can be changed based on our lives.
What is the Humanistic Approach to Personality?
theory is that personality comes about as we try to maximize our well-being and autonomy.
What is a self-report measure?
any test in which a person is asked to evaluate themselves on questions, which often rank on scales from “not at all like me” to “very much like of me”.
What happens when self-report measures are made poorly? Why?
they are prone to extreme bias
that makes them invalid measures.
What is the Barnum/Forer effect?
a common phenomenon whereby people take extremely general descriptions to be highly specific to them and their personality.
What effect do self report measures suffer from?
The Barnum/Forer effect
What are some examples of phrases that show the Barnum effect?
“you have a great need for others to like and admire you, but you tend to be critical of yourself.”
“at times you are extroverted and sociable, while at other times you are introverted and reserved”
why would most psychologists reject the Myers Briggs test?
because the research behind this test was done by people with vested interests. This research has actually been proven to be false. Statements are too general.
what are the 3 things we can do to make a good personality test?
- Indirect self reporting
- Measure tendency to bias
- Converge Multiple Methods
