Research Methods Flashcards
What is the experimental method?
The experimental method is a scientific method involving the manipulation of variables to determine cause and effect?
What is operationalisation?
Clearly defining variables so that they can be manipulated
What are extraneous variables?
Other variables that could affect the DV that are controlled so that they do not vary across any of the experimental conditions
What are confounding variables?
Confounding variables are variables that confuse the results by affecting the DV.
What are demand characteristics?
Features of a piece of research that allow the participants to work out its aim and/or hypotheses. Participants may then change their behaviour and so frustrate the aim of the research.
What are investigator effects?
A research effect where the researchers influence participant responses.
What is a laboratory experiment?
Experiments conducted in a controlled environment allowing the establishment of causality.
