experiment settings -

• what are weaknesses of field experiments?


  control over participants is limited.
• what are weaknesses of lab experiments?


  can create demand characteristics that can affect the behaviour of participants.
• what are strengths of lab experiments?


  the researcher has a high level of control over the experiment so they can examine exactly what they want.
• what are strengths of field experiments?


  takes place in a real life setting.
• what are weaknesses of quasi / natural experiments?

  • as participants know that they're participating in an experiment they may be affected by demand characteristics.
  • can't be sure that the results are due to the manipulation - many uncontrolled variables.
• what are quasi / natural experiments?


  an experiment that is done in the participants natural environment.
• what are the types of experiments?

  • laboratory experiments.
  • field experiments.
  • quasi / natural experiments.
• what does laboratory experiment mean?


  takes place in a controlled setting such as a laboratory or a classroom.
• what are strengths of quasi / natural experiments?


  researchers can see how people behave naturally.
• what are field experiments?


  take place in the participant's natural setting (e.g. studying nurses in a hospital).
