1. Social explanations

         • Zimbardo (1969) carried out an investigation into individuation and increased aggression. He took two groups of four women and asked them to deliver electric shocks to another student. the first group wore lab coats, hoods which hid their faces and sat in separate cubicles so they couldn't see each other or the aid student. The second group wore normal clothes, name tags and sat so they were able to see each other and the aid student
