types of experiments

Question 1

laboratory

Answer 1

• researcher manipulated IV
• artificial setting

Question 2

field

Answer 2

researcher manipulates IV
natural environment

Question 3

natural

Answer 3

IV is naturally occurring
real life setting

Question 4

quasi

Answer 4

IV occurs naturally within a pp so pp’s can’t be randomly allocated to a condition
artificial setting

Question 5

strengths of laboratory

Answer 5

— easy to replicate > high degree of control > high level of reliability
— high level of control over EV/CV > establish cause and effect between IV and DV > high internal validity

Question 6

limitations of laboratory

Answer 6

behaviour could change > high level of control > demand characteristics
artificial setting > lacks ecological validity

Question 7

strengths of field

Answer 7

high ecological validity > natural setting
no demand characteristics > pp’s don’t know they’re apart of research

Question 8

limitations of field

Answer 8

less control over EVs > lowers validity
ethical issues > lack of consent

Question 9

limitations of field

Answer 9

less control over EVs > lowers validity
ethical issues > lack of consent

Question 10

strengths of natural

Answer 10

ethical
less chance of demand characteristics > real life setting

Question 11

limitations of natural

Answer 11

time consuming/ complex issues being studied
often issue being studied are rare > difficulty to find

Question 12

strengths of quasi

Answer 12

carried out under control conditions so replicable and reliable
allows research to occur ethically

Question 13

limitations of quasi

Answer 13

confounding variables > pp’s can’t be randomly allocated to a condition
can’t establish cause and effect between IV AND DV
