Research Methods Flashcards
What is the difference between an experimental method and an experimental design?
Method = Where it takes place + manipulation of the IV and it’s effect on the DV
Design = How it takes place = how participants are allocated to the conditions
What are the three features of a laboratory experiment?
1) Controlled environment
2) Researcher has complete control over IV and DV
3) Participants are randomly allocated to conditions
What are the three features of a field experiment?
1) Natural environment
2) Set up - Doesnt happen naturally
3) Researcher has control over IV
What are the two differences between a field and laboratory experiment?
1) In field, EVs cannot be controlled
2) Laboratory experiments can be replicated more easily
What are two features of a natural experiment?
1) IV is natural
2) Environment is natural
How do natural and field experiments differ?
Natural - natural IV
Field - Researcher has complete control over the IV
What are the two features of a Quasi experiment?
1) IV is a feature of the participants
2) Researcher is not able to randomly allocate participants to different conditions of the experiment
How does a quasi experiment differ from a field experiment?
Field - researcher has complete control over IV
Quasi - IV is a feature of the participant
What are the two strengths of a laboratory experiment?
1) Easy to replicate
2) High cause and effect
What are the two limitations of a laboratory experiment?
1) High demand characteristics
2) Poor ecological validity
What are the two strengths of a field experiment?
1) High ecological validity
2) Fewer demand characteristics
What are the three weaknesses of a field experiment?
1) Lots of EVs - lower cause and effect
2) Difficult to replicate exactly
3) Ethical implications
What are the two strengths of a natural experiment?
1) High ecological validity
2) Allows us to investigate areas that are impossible experimentally due to ethical issues
What are the three weaknesses of natural experiments?
1) Lots of EVs - lower cause and effect
2) Difficult to replicate exactly
3) Might have to wait a long time for the IV to occur naturally
What is the strength of a Quasi experiment?
1) Offers us a solution to research areas that might be difficult for ethical or practical reasons
