1
Q
Laboratory experiment
A
Conducted under controlled, artificial
conditions.
2
Q
Features of laboratory experiment
A
- Researcher manipulates the independent variable (IV) whilst measuring the dependent variable (DV).
- Conducted under both experimental and a control conditions. Researcher randomly allocates participants to experimental or control conditions.
3
Q
Strengths of lab experiment
A
- High level of control; can infer that the IV caused the DV.
- Easy to replicate so that reliability can be checked.
4
Q
Weaknesses of lab experiment
A
- Problems of demand characteristics (participants act aganist or for what the experiement is)
- Low ecological validity
5
Q
Field experiment
A
Conducted in a natural environment
6
Q
Features of a field experiement
A
- IV is still manipulated by the researcher and the DV is still measured.
- Participants are unaware that they are being researched.
7
Q
Strengths of a field experiment
A
- High in ecological validity.
- Fewer demand characteristics.
8
Q
Weaknesses of a field experiment
A
- Unethical: participants are unaware of the research.
- Extraneous variables affect results.
9
Q
Natural experiments
A
A natural experiment is when a research does not deliberately manipulate an IV, they take advantage of a ‘naturally occurring’ IV. The DV of a natural experiment may be tested in a laboratory, in the field or online.
10
Q
Strengths of natural experiments
A
- Allows research where the IV can’t be manipulated for practical or ethical reasons; a range of behaviours can be investigated.
- Allows researchers to investigate ‘real’ problems, such as the effects of a disaster on health, which can help more people in more situations.
11
Q
Weaknesses of natural experiment
A
- Researcher has no sense of control over extraneous variable.
- Doesn’t allow for replication
Can’t establish cause and effect
