1
Q

Define Laboratory Experiements

A

When an experiment takes place in a highly controlled environment/condition

2
Q

What are the Strengths of Lab Experiments?

A
  • High control over EVs
  • High internal validity
  • Easily Replicable
3
Q

What are the Limitations of Lab Experiments?

A
  • Low External Validity
  • Low Mundane Realism (artificial tasks - also impacts generalisability)
  • Demand Characteristics are likely
4
Q

Define Field Experiments

A

An experiment where the IV is manipulated in a natural setting

5
Q

What are the strengths of Field Experiments?

A
  • High Mundane Realism
  • Produce authentic behaviour
  • High external vaildity
6
Q

What are the limitations of Field Experiments?

A
  • Lack of control over EVs
  • Ethical Issues; consent needs to be ensured
  • Replicability
7
Q

Define Natural Experiments

A

When the IV is pre-existing and would have changed even if the experimenter was not interested

8
Q

What are the strengths of Natural Experiments?

A
  • Provide opportunities that may have not been previously taken due to ethics
  • High External Validity
9
Q

What are the limitations of Natural Experiments?

A
  • Generalisability

- Impacts methodology as ppts may not be randomly allocated

10
Q

Give an example of a Natural Experiment

A

Rutters Romanian-English Adoptee study

11
Q

Define a Quasi Experiment

A

When the IV is based on an existing difference between ppts - the variable simply exists

e.g. age, gender

12
Q

What are the strengths of Quasi Experiments?

A
  • Often done in controlled conditions
13
Q

What are the limitations of Quasi Experiments?

A
  • Ppts cant be randomly allocated so confounding variables are likely
