Harlow’s work was based in a laboratory and was a long term experiment using monkeys. The treatment of the animals was seen as poor and unethical. Certain parts to the experiments could even be called cruel. Harlows work on attachment was based around the theory that attachment was formed to things that provided comfort to the animals, after discovering that they did indeed seek solace in more comfortable items which happened to be either a sanitary pad or its terry-cloth mother. The monkeys were taken completely out of their natural habitats and forced to live whatever way Harlow saw fit which is now not allowed. Since Harlow’s work there have been a lot of changes on experiments including animals and Harlows work would not have been allowed today.
Mary Ainsworths work was not taken place in a laboratory. She did her strange situation study in a room where the children were with their mothers most of the time and if not they were outside the room and could always see their children. The monkeys in Harlows work were completely taken away from their mothers. Ainsworth wasn’t working to see “contact comfort” but was observing how a child reacts when their mother leaves them, if they notice, if they become inconsolable or if they were easily comforted. If the children became to distressed then the parent would come in to comfort the child and stop the experiment. This was not the case in Harlows work with the monkeys.
In Harlows work he introduced the “the iron maiden” mother which was to take place as a abusive parent. The iron maiden blew pressurised cold air out at such a force that it threw the infant monkey across the cage. It would also be able to push the monkey away.
