Experiment Type Flashcards
1
Q
Definition of lab experiment
A
Artificial task in artificial setting
2
Q
Definition of field experiment
A
- done in natural environment of the participants
- IV is manipulated
3
Q
Definition of natural experiment
A
- done in the participants’ natural environment
- no control over IV (occurs naturally)
4
Q
Definition of quasi experiment
A
- IV is not manipulated
- difference between participants exists naturally (cannot be changed)
5
Q
Strengths of lab experiment
A
- Easily replicable due to standardised procedure
- High degree of control over extraneous variables
6
Q
Limitations of lab experiments
A
- Low ecological validity
- Low external validity
- Demand characteristics/experimenter bias
7
Q
Example of lab experiment
A
Milgram’s experiment on obedience (shock)
8
Q
Strengths of field experiments
A
- High ecological validity
- No demand characteristics (if the study is covert)
9
Q
Limitations of field experiments
A
- Less control over extraneous variables
- Difficult to replicate
10
Q
Example of field experiment
A
Holfing’s study on obedience (hospital)
11
Q
Strengths of natural experiments
A
- Very high ecological validity
- No demand characteristics
- Useful in situations where it is unethical to manipulate the IV (e.g. stress)
12
Q
Limitations of natural experiments
A
- Expensive and time consuming
- No control over extraneous variables
- Not replicable
13
Q
Example of natural experiment
A
Cherokee one
14
Q
Strengths of quasi experiments
A
- Useful when it is unethical to manipulate the IV
- High realism and ecological validity
15
Q
Limitations of quasi experiments
A
- Less reliable because of confounding environmental variables
- Must wait for IV to occur
- If participants are aware they are being studied = less internal validity
