- Zimbardo’s Stanford Prison Experiment showed how being in prison can have a negative effect on the individuals mental health.
o E.g. one participants mental health was so badly affected they had to withdraw from the study.
o This is potentially due to the treatment from the guards and withdrawal of freedom.
o This gives the concept of custodial sentencing giving poor mental health supporting research.
o However caution should be taken when generalising to real prisons as the setting was experimental and therefore ecological validity is low.
