What is science?
Philosophy of science in Psychology
History of Personality & Social Psychology
Present day of personality & social psych
-We have explicit + implicit assumptions when we do scientific studies
- Explicit assumptions: in differential psych, assumes that intrapersonal factors (within the individual) can be understood > understanding individual factors can help predict behaviour + describe future behaviour, factors of peoples personalities can be separated + verify introspection (self-reflection) through people’s behaviour
- Social psych indicates that intrapersonal effects are measurable, significant + have similar effects across people > social factors have similar impacts broadly. If they don’t, factors can be broken down + build a framework (e.g. take a breakdown of two people meeting for a data + find the commonalities between them + change one thing to see what happens such as wearing a fur suit vs not)
Implicit assumptions: The tools we use (e.g obs) can analyse information + we can construct an overarching theory of behaviour using these methods + tools
Methods of data collection
How we collect data
Macrolevel issues of studies
Validity
-How do we know what we found is correct > more types of validity exist
- Basic types of validity includes internal vs external > internal: does it measure what it claims to + external: can it be applied externally to a situation
-Specific types of validity too like criterion, content, construct, discriminant
• Criterion validity: do the measures link to an observable outcome (current + future) essentially, criterion validity is predictive + concurrent validity combined (predictive = does the test predict later performance on a related criterion, concurrent = does the test relate to an existing measure) > basically compares the current test to existing valid measures (criteria) > links to sensitivity
• Construct validity: = to internal validity for things which are not operationally defined > does it measure what it says it will? Construct validity must be investigated whenever no criterion or universe of content is accepted as entirely adequate to define the quality to be measured.
• Content validity: measure all parts of the domain being measured (e.g. depression test must assess all sub-types of depression or else lacks content validity)
- Discriminant validity: Does it measure things which are different from the theoretically related things? Links to specificity (do we find things we didn’t intend to)
