Social Psychology Lecture 1/ 2012- Ostovich
Scientific study of how people affect behavior, cognition and how they are influenced by the
presence of at least one other person
Very broad range of topics
Conformity- how most humans are sheep
o Persuation- we have great various ways to persuade people
o Group- behaviour--behave insensibly in groups
o Sexuality- human mating and sexuality
Social Psych is not common sense
o Ex. Do opposites attract?
Do birds of a feather flock together?
The Scientific Method
Observation Theory- leads you to hypthesis (predictions)
If your test agrees with your hypothesis -> adds to theory and observations
If tests fails to confirm, modify hypothesis
Do scientists "prove" stuf?
We don't have fact, we have theories and findings that provide support
Ways of testing hypothesis
Data collection decisions
1. Control ("internal validity")
2. Generalizability ("external validity)
There is a trade-off between the 1 and 2
No experimental research=> control goes Down
o Correlational studies (includes survey research)
o Field studies (observational)
o Research Question
How are 2 or more variables related?
Ex. Personality correlated with behaviours
o Pre-existing Data
Ex. Elevation level and athletic achievement
Ex. Cloud covver and amount of rain
What does it look like?
Do they go in one direction or other
+1 means it is on or close to line of best fit (positive)
-1 close to line of best fit (negative) Zero correlation
**Correlations DOES NOT equal Causality
Ex. A-->B A
B-->A C< Therefore cannot make causal statement
The "Third Variable" Problem
Increasing ice cream sales and violent crime
