Milgram
Aim: to investigate whether individuals would obey authority figures
Ethical issues:
- Milligram was used- participants believed that they were shocking a real person, however Milgram argued that this would help eliminate response and participant bias- leading to more reliable and value results
- Participants were not protected- they were exposed to very stressful situations which could have potentially led to psychological harm. Miligram argued that the participants would be debriefed and that their stress levels would decrease
- Debriefing- this was successfully done and it was ensured that no participants were exposed to any real psychological or physiological harm
- Right to withdraw- this was permitted however not enforced; participants were pressured to:
Please continue.
The experiment requires that you continue.
It is absolutely essential that you continue.
You have no other choice, you must go on.
Little Albert
The experiment requires that you continue.
It is absolutely essential that you continue.
You have no other choice, you must go on.
Aim: to see how possible it is to remove the fear response in the laboratory.
Ethical issues:
- Little Albert was not protected from psychological harm; a fear was forced upon him
- Confidentiality was successful- Little Albert was not his real name; his identity remained hidden
- Lack of informed consent- Little Albert's parents did not know what their 9 month old son would suffer form in the future
- Right to withdraw- this was permitted and his mother removed from the hospital, however this meant that the negative effects that he gained were not removed
--- this experiment was very useful for psychologists as it helped them gain a better understanding on how phobias could be learnt
Asch
Aim: to investigate whether perceived group pressure by a majority can influence a minority in an experimental set up that is not ambiguous
Ethical issues:
- Participants were not protected form psychological stress and pressure which could have occurred if they decided to disagree with the others
- Deception was used- Asch told the volunteers that they were taking part in a 'vision' test to avoid response bias; Asch argued that this was neccessary to produce value results
Zimbardo
Aim: To investigate how readily people would conform to the roles of guard and prisoner in a role-playing exercise that simulated prison life.
Ethical issues:
- Lack of informed consent- experimenter himself did not know what would happen in the experiment. participants did not 'agree' to be 'arrested' at home
- Prisoners were not protected from psychological harm (they were put between real prisoners), Zimbardo stated that emotional distress could not be predicted prior to the experiment
- Participants were debriefed at the end of the experiment
Overall, the experimenters always argue that unethical experiments lead to more reliable and valid results and they always seem to find an excuse for ethical considerations that were not followed
