Key Terms
Aim: What you are trying to find out- purpose of the study
Causal Relationship: When one event causes another
Confidentiality: Participants' data should be kept anonymous unless they have given consent to make it public.
Consent: Researchers need to obtain the participants' full consent to take part in the study.
Control Condition: This is a condition that doesn’t involve changing the IV. E.g. the Tourette’s condition in Baron-Cohen
.
Correlation Co-efficient: Number between -1 and +1 and states how strong a correlation is.
Debriefing: Participants understanding of the research after the study has taken place.
Deception: Participants should never be deliberately mislead without medical (or any other valid) justification.
Demand Characteristics: Features that inform participants about the aim and can influence their behaviour or results. Can be reduced by single blind technique and double blind technique
Dependent Variable: A Dependent Variable is the “thing” that is being measured in the experiment (there can be more than one!).
Descriptive Statistic: Basically it’s just the mathematical things we use: Mean, median and mode!
Double-blind technique: Both participant researchers are unaware of aim of the experiment
Ecological Validity: How well a study can be related or reflects everyday real life situations
Empirical – This is a practical way of looking at something, usually realistic and experimental.
Ethics: Set of guidelines that psychologists should follow- participants should not be embarrassed, have loss of self-esteem, changing a person etc.
Event Sampling: When the researcher records an event every time it happens
Experiment/Alternative Hypotheses: predicts that one variable will affect another. E.g. People who listen to music
