Compare the methods of Sherif et al. (1954) and Baddeley (1966).

Sherif used a field experiment at a summer camp, giving high ecological validity but little control; Baddeley used a laboratory experiment with word lists, giving tight control but low ecological validity.

Compare the ethics of Watson and Rayner (1920) and Rosenhan (1973).

Watson and Rayner conditioned fear in a baby without removing it, causing harm without proper consent; Rosenhan's pseudo-patients deceived hospital staff, who did not consent to being studied.

Compare Raine et al. (1997) and Baddeley (1966) as examples of psychology as a science.

Both are objective and quantitative: Raine used PET scans to compare brain activity in murderers and controls, and Baddeley measured recall under controlled conditions, so both could be replicated.

What ethical issues does Sherif et al. (1954) raise?

The boys were not told they were being studied, were deceived about the purpose of the camp, and were deliberately set against each other, causing hostility and distress.

What issues and debates does Raine et al. (1997) raise?

It is reductionist in linking violence to brain activity, socially sensitive because it could be used to label people as violent, and relevant to the nature-nurture debate, as brain differences could be caused by experience.
