Social Influence Flashcards
What is meant by Internal Validity?
Are we measuring what we are intending to
Give examples of Individual differences
Memory capacity, Language, Mental heath and Learning difficulties
What is meany by External Validity?
Do the people in the study the population ?
What is meant by Standardisation?
Keeping the experience of the participants the same
What is meant by the Independent Variable?
The thing we/the researcher are changing
What is meant by the Dependant Variable?
The thing we/the researcher are measuring
What is meant by a Null Hypothesis?
Experiment has no effect
What is meant by an Alternative Directional Hypothesis?
A prediction based off of previous evidence
What is meant by an Alternative Non Directional Hypothesis?
A prediction based off of no previous evidence
What us meant by an Extraneous Variable?
Anything extra that affects the DV
Give an example of Extraneous Variables
Stress, confidence , age and gender, location, appearance
What is a Laboratory experiment?
A controlled experiment conducted in an artificial setting
What is a Field experiment?
A controlled experiment conducted in the participants natural environment
What is a Natural experiment?
Where you do not affect the independent variable yourself, usually because it would be unethical
What is a Quasi experiment?
Where you can’t randomly allocate people to group because they are already naturally in these groups
What are levels of IV?
Each condition of an experiment, not a controlled group
What happens in Independent groups?
Each participant only takes part in one condition/level of the IV. Their results are then compared to different participants taking part in other conditions
What happens in Repeated measures?
Each participant takes part in all conditions/levels of the IV. Their performance on each condition is then compared
What happens in Matched pairs?
Each participant only takes part in one condition. However participants are matched on important criteria beforehand and assigned a group to give similar participants to each condition. Criteria can include age , gender, IQ and height
What are Demand characteristics?
Where participants figure out the aim of the research and change their behaviour, either making them try and ruin the experiment, make it work for the researcher or be socially desirable to others-reduces Internal Validity
