Famous Psychology Experiments


Conducting Psychology Experiments


Hypothesis

  • Scientific method

  • Hypothesis formulation

=


Operationalization

  • Operationalization: to put an experiment into a form that allows researchers to test the hypothesis

  • Independent variable: the variable that researchers control

  • Dependent variable: the variable that researchers are studying

  • What other questions should the researchers ask?

Independent variable

Dependent variable


Operationalization (continued)

  • Confounding variables

  • Reliability

  • Validity

SCARY

= ?

What makes a movie scary?

How can we tell if a child has had a nightmare?

What else might cause nightmares?


Conducting the experiment

Experimenting, Recording Results, Conclusion

Recording the results

Drawing conclusions

does cause


Correlation vs. Causation

Correlation versus causation: just because two things are related doesn’t mean one thing caused the other

Just because

happened

happened and then

doesn’t necessarily mean that

caused


Replication and Theory Development

  • Replication

  • Theory development

=

Experiment 1 results

=

Experiment 2 results

=

Experiment 3 results

=

THEORY:


Ethical Issues

  • Is it right to experiment on people?

  • What limits should there be?


Ethical Issues

  • Is it right to experiment on animals?

  • What limits should there be?
