Psychology Chapter 2
The Scientific Method of Psychology
Naturalistic: e.x: Jane Goodale would move in with chimps and observe them and learn how
the behave
>problem was the monkeys couldnt be natural with something unnatural (as a human)
living with them
Correlation studies: relationship between two behaviors. Not powerful scientificaly
Experiments: tool that allow you to manipulate a variable, and see the effect it has
Variable: height, age, weight
Independent variable: experimenter manipulates
>under experimenters control
Dependent: variable being measured. Seeing if independent variable affects
>as I manipulate the independent variable, does anything happen to the dependent
variable
>determines cause and effect (assume causeality)
Control condition: reflect normal behavior, non manipulated behavior
Experimental group: represent behaviour when something is added/subtracted or
manipulated
Operational definition: taking something vague and general, and turned it into something
specific you can measure
Independent: whether or not we participate (how much we participate)
Dependent: measuring marks (how students who participate, do better)
Operational definition: clickers, rewards kids for participating, stands there waiting for
answers
Validity: how well the operational definition does what its supposed to do
>i.e. student who things marks aren't a way to test how much a student knows
>variable wasnt manipulated well
Test the same hypothesis in different ways. (using different operational definitions)
> same results=confirms hypothesis
Hypothesis example: when somebody feels low self esteem, thats when they become most
prejudicial to out groups (anybody different from you)
>study: table set up with slides, student would let subject in saying sorry im late, ive
got an important presentation and I had to get slides in order. While person was filling out
forms, the experimenter would make the slides fall of the table. They would then blame it
on the subject, make them feel really bad. Did that to some subjects, and not to others.
Manipulation of self esteem.
>then had them watch a movie about French Canadians. Group that was made to feel
bad, was more prejudicial towards french Canadians

OneClass has been such a huge help in my studies at UofT especially since I am a transfer student. OneClass is the study buddy I never had before and definitely gives me the extra push to get from a B to an A!
