Experimental Method^ Flashcards
1
Q
Laboratory Strength
A
+ high level of control
+ high reliability
+ can obtain direct link between IV and DV
2
Q
Laboratory Limitation
A
- lack ecological validity
- higher chance of investigator and participant effect
- artificial materials
3
Q
Field Strength
A
+ conclude cause and effect
+ high level of ecological validity
+ reduce participant effect and demand characteristics
4
Q
Field Limitation
A
- less control over EV’s
- time consuming
- random allocation to condition is difficult
5
Q
Natural Strength
A
+ useful when unethical or hard to manipulate the IV’s
+ high level of ecological validity
6
Q
Natural Limitation
A
- problems with internal validity
- can’t control EVs so we can’t conclude cause and effect
- no random allocation
7
Q
Quasi Strength
A
+ control over IV
+ ecologically valid
8
Q
Quasi Limitation
A
- does not manipulate variation in the IV
- no random allocation
- hard to infer cause & effect
9
Q
Operationalised Variables
A
clear defining variable in terms of how they are measured
- beh categories
10
Q
Non - Operationalised Variables
A
can’t be clearly measured
