What is personality?
A set of personality traits and mechanisms within the individual looking at the way we behave/feel/think across a variety of situations over a long period of time
Ways to test personality traits
Self reports( bias due to social disirablility, but data collection is easier Observer reports ( may only oberserve you in particular situations so need a range of observers e.g. Friends/parents... but can be more reliable
Vazire and Carlson (2011) showed self reports better for low observabiloty and evaluativeness e.g. Anxious. But observer reports better for high observability low evaluativeness (e.g. Talkative) and low observailitt high evaluativeness (e.g. Intelligence)
What is reliability?
The degree it produces consistent results, does it measure the same construct?
What is internal consistency reliability
The extent to which items correlate with each other
What is test-retest reliability?
The degree of consistency between scores across different measurement conditions
What is validity?
Does it measure what it claims to measure?
What is content validity?
The extent it measures al relevant features but not irrelevant features
What is construct validity?
The measures assess the same construct as it’s meant to measure. Made up of convergent and discriminate validity
What is convergant validity?
Correspondence with the measures, these characteristics should be correlated +/-
What is discriminat validity?
Correspondence with measures assessing characteristics unrelated to what’s it’s unintended to measure, meaning they shouldn’t be correlated
What is criterion /predictive validity?
Relations with relevant outcome variables
