Psycholgy - Lab experiments

Advantages

  • Relatively easy to replicate.
  • Tighter control of variables. Easier to comment on cause and effect.
  • Enable use of complex equipment.
  • Often cheaper and less time-consuming than other methods.
  • Yields quantitative data which can be analysed using inferential statistical tests.

Disadvantages

  • Demand characteristics - participants aware of experiment, may change behaviour.
  • Artificial environment - low realism.
  • May have low ecological validity - difficult to generalise to other situations.
  • Experimenter effects - bias when experimenter's expectations affect behaviour.
