experiments

Question 1

strengths of lab experiments

Answer 1

P = easy to replicate
E = take place in an artificial environment that is highly controlled and uses a standardised procedure
E = goo because the study can be replicated and the reliability of results can be checked

Question 2

weakness of laboratory experiments

Answer 2

P = criticised for lacking ecological validity
E = this is because experiments take place in an artificial environment which is highly controlled, often with tasks that are unlike everyday tasks
E = bad because participants are unlikely to show their natural behaviour making it difficult to generalise results

Question 3

strengths of field experiments

Answer 3

P = praised for having ecological validity
E = because field experiments take place in the participants more natural environment often with a task that resembles an everyday task. = more likely to show natural behaviour
E = good because participants are likely to show their natural behaviour meaning results can be generalised

Question 4

weakness of field experiments

Answer 4

P = criticised for raising ethical issues
E = because often participants are unaware they are talking part in an experiment
E = this is bad because it is the right of the participant to give informed consent, have the right to withdraw and not be deceived

Question 5

strengths of natural experiments

Answer 5

P = praised for having high external validity
E = because they involve the study of real-life issues and problems as they happen
E = good because it means the findings are more relevant to real experiences

Question 6

weaknesses of natural experiments

Answer 6

P = criticised for being hard to replicate
E = this is because the IV has not been directly manipulated by the researcher, it has occurred naturally over time
E = bad because the research cannot be repeated and the reliability of the results cannot be checked

Question 7

strengths of quasi experiment

Answer 7

P = there is often high control
E = this is because they are often carried out under controlled conditions
E = this is good because replication is possible

Question 8

weaknesses of quasi experiments

Answer 8

P = participants are not randomly allocated
E = this is because the experimenter has no control over which participants are placed in which condition as the IV is pre-existing
E = this is bad because participant variables may have caused the change int= the DV acting as a confounding variable

Question 9

lab, field, quasi, natural - IV is manipulated or not?

Answer 9

lab = IV is manipulated
field = IV is manipulated
quasi = IV is no manipulated
natural = IV is not manipulated

Question 10

lab, field, quasi , natural - cause and effect can be established?

Answer 10

lab = can be
field = can be
quasi = cannot be
natural = cannot be
