Outcome:
Why complex human behaviours can rarely can be explained by one casual factor
What is wrong with pseudoscience
Correlation vs. causation
seudoscience :science imposters (looks like sciencewithout the credible evidence to back it

ultifaceted Levels of Psychology
M
Psychology spans multiple levels of analysis->considering multiple factors is essential for a
complete understanding
Social/Cultural Influences Psychological Biological
Involves relationships with Involves thoughts, feelings, Involves molecules and brain
others and personal and emotions structures
relationships
Environment (included social
norms)
Correlation Vs. Causation
orrelation:means 2 variables are related or changetogether - statistical relationship
C
between 2 variables
● Positive correlation: if both variables go up
● Negative correlation: one variable goes up and the other goes down
● Correlationonly shows a relationship, not a cause/reason
● Example: Ice cream sales increasing along with drowning deaths
○ Ice cream is not causing people to drown
○ Need to turn to science to understand the reason behind the correlation of
these 2 separate things
■ Creating theories and testing them using the scientific method
Causation:one causes the other - one variable directlycauses the other variable
● To be able to claim causation, 3 key steps
(1) The cause comes before the effect
(2) There is a direct mechanism
(3) Other explanations are ruled out
● Example: smoking and lung cancer
○ There is biological and controlled evidence that shows smoking causes
increased probability of getting cancer

he Third Variable: a hidden factor that influences both variables and makes it appear as if
T
there is a causation between two variables (creating a false impression of causation)
● Bringing back example of icecream sales and drowning
○ Ice cream does not cause drowning
○ The third variable here is the hot weather
■ In hot weather, people are more likely to buy ice cream
■ In hot weather, more people going out to swim, more chances of
someone drowning

Module 2: Research Methods-September 11-18, 2025
Outcomes
Identify Different Research Designs
Interpreting the correlation coefficient
Dependent vs. Independent variables
Measures of central tendency and dispersion
Science is NOT an area of study BUT rather an approach to asking questions
- Open minded attituderegardless of preconceptions
- Acceptance of evidence that is against own biases
The Bystander Effect-The Case of Kitty Genovese
- Case study: Woman brutally stabbed to death with 38 bystanders who witnessed the
murder
- Question developed as to why there was a lack of social responsibility on the
bystanders
- Application of science to this:IDENTIFY, GATHER,TEST, ANALYZE, BUILD
- (IDENTIFY)Curiosity as to why 38 people ignored amurder
- (GATHER)A diffusion of responsibility may have occurred->hypothesis
developed: If multiple bystanders are present then the principle of “diffusion of
responsibility” will decrease each bystanders likelihood of intervening
- (TEST)Create an emergency in a controlled settingutilizing variables
- Variable: anything that can be measured; anything that varies between
environments/individuals
- Expectindependent variable (manipulation) to havean effect on our
dependent variable (measurement)
- Independent variable (manipulation):# of people inthe room
- Dependent variable (measurement):time to notice smoke/report
