Sharks live as long as they do because they don’t experiment. They are extremely picky
When they actually attack a human, it is because of prey confusion.
The simplest experiment involves two groups:
Control group: group that exhibits natural behaviour
Experimental group: group that demonstrates how behaviour changes.
An experiment typically involves contrasting ‘behaviour’ across two or more conditions
that differ in some way that should matter (i.e. affect ‘behaviour’), according to some
Dependant variable is the variable that reflects behaviour of interest.
Independent variable is the variable that was changed to create critical difference
What makes it tricky is the need to make the connection between abstract theoretical
ideas and concrete variables that can be manipulated or measured.
Example: Prejudicial behaviour is linked to our self-esteem?
Economy can bring on prejudice:
When the economy is bad, people lose jobs (loss of self-esteem), and they take it
out on ‘out groups’ (groups that are different from your own).
o This is a ague theory. How do we take it to experiments?
Manipulate self-esteem to get one group to have intact self-esteem and other half to
take a hit to their self-esteem.
In this experiment, a stack of slides was knocked over and the subject was
blamed for it despite it not being their fault.
How do you measure/define prejudice? People do not openly display their own
prejudices? PSYA01 Sept. 24/26
