experiments Flashcards
1
Q
experiments
A
Look at a measureable change in the DV caused by a change to the IV
2
Q
lab experiments
A
high control over what happens, takes place in a lab
3
Q
field experiments
A
take place in a natural setting, IV manipulated by experimenter
4
Q
natural experiments
A
natural or lab setting, IV is not changed by the experimenter it varies naturally e.g. age, race
5
Q
lab strengths
A
- EV’s can be controlled, so cause and effect can be established
- Used of standardised procedures permits replication, can demonstrate validity
6
Q
lab weaknesses
A
- behaviour in a lab is less normal so difficult to generalise
- pp’s may change their behaviour because they are aware they are being watched
7
Q
field strengths
A
- more realistic than lab exp’s as in a natural environment
- can use standardised procedures so some control
8
Q
field weaknesses
A
- may lose control of EV’s so difficult to show cause and effect
- ethical issues because p’s not aware of the study
9
Q
natural strengths
A
- may have high validity because of real-world variables
- can standardise procedures so some control over EV
10
Q
natural weaknesses
A
- few opportunities to do this kind of research as behaviours may be rare
- may be EV’s because pp’s not randomly allocated to conditions
