Science and Psychology
What is science?
A way of discovering truth and evaluating ideas.
Formalizes a typical human process.
How does it proceed?
Observe --> explain --> predict --> observe
Observation --> Theory --> Hypothesis --> Research Project
You then apply the outcome of your observation to your hypotheses and
Generally, try to disprove theories.
Psychology is applying the tools of science to the study of the human.
Theories, Hypotheses, and Observations
Set of related ideas that explain observations
Explains most findings
Can be applied to new situations
Theories are general
Theories are parsimonious
Theories are falsifiable
A prediction for a particular context
Based on a theory
Cause and Outcome
Tells you how to design a research project
An empirical fact
Outcome of a research project
The misinformation effect –
Presentation of post-event misleading information leads to memory errors.
Source Monitoring Theory
Repetition and the misinformation effect
In this class --
You make one round of the process
Keep in mind the basic loop
Experiment --> Theory --> Hypothesis --> Experiment
You start with a basic issue
You find the theories concerning that issue
Those theories make claims about what causes things
You make predictions based on what you expect to cause what
You design experiments to vary cause and measure outcome
There should be plenty of theory and work in research domains to make
-- precise predictions
-- well controlled experiments
