He used 16 baby monkeys to study attachment behaviour.
What was the aim of Harlow's study?
Investigate the mechanisms of attachment, focusing on the importance of emotional comfort over nourishment.
How did he test what was more important for the monkeys?
He scared them with a loud noise and observed where they would run to. They had a 'wire monkey' which provided them with food and a 'puppet monkey' which was soft and comforting. He saw that the monkeys ran to the softer monkey for comfort.
