Obedience- Milgrams experiment (1963)-
CPS- Sheridan and King (1972) used students shocking a puppy – 54% of men and 100% of women gave what was said to be a lethal shock , making mil grams study genuine since people were the same when the shocks were real.
CPW- Perry (2013) confirmed that only 2 anticipates believed the shocks were real, so the participants were responding to demand characteristics by trying to fulfil the aims of the experiment.
