Outline Lorenz’s and Harlow’s animal studies of attachment. Discuss what these studies might tell us about human attachment. [16 marks]
Lorenz studied attachment by randomly dividing 12 goose eggs into two groups. The geese were hatched in a natural environment with their mother in condition one. In condition two, they were incubated and the first thing they saw was Lorenzo. Their behaviour was recorded, and Lorenz found that through imprinting the geese attached to the first thing they saw within a critical period. This meant the control group followed the mother while the incubator group followed Lorenz, seeing him as their primary attachment. Using a controlled environment, Harlow used monkeys and reared them with two mother surrogates: one with plain wire dispensing milk and the other being cloth-covered with no milk. Time spent with each was recorded, and he found that time with the cloth-covered mother was longer, especially when fear conditions were added showing contact comfort is more important than food for attachment.
From these studies, we see that early neglect has long-lasting effects as Harlow's monkeys became antisocial, aggressive, and neglectful towards their children causing some of them to be killed. Applying this to humans, we could say neglect can lead to forming bad or a lack of relationships. Bowlby supported this with the internal working model as your primary attachment will form a schema for later relationships in life, if you are neglected you cannot form a healthy schema.
Lorenz and Harlow both agreed on the critical period, a “window of opportunity” for attachment. Lorenz found that if the geese did not have a mother figure, they would not form an attachment. Harlow argued that there was a 90-day critical period in which the monkeys should attach to their primary figure, if not the long-term damage would be irreversible. However, we cannot apply this to human attachment. Human studies have shown the critical period is more like a sensitive period as we have seen children recover from early neglect, for example, Romanian orphans. Research by Bowlby indicates this sensitive period can last up to 5 years which tells us humans can recover from early neglect much better than shown in animal studies.
Human attachment will likely not reflect the way animals attach so generalising animal studies to humans may not be valid. This is because Lorenz’s geese have a more simplistic way of attaching - through imprinting. If we are generalizing, Harlow’s study would be better suited because of the use of the mammalian species although the human brain is still more complex than a rhesus monkey. Human attachment therefore may have similarities with Harlow's findings but human attachment could be more complex.
Harlow is also supported by human studies such as Schaffer and Emerson. They argued responsiveness from the mother was more important than food for attachment through actions such as reciprocity and interactional synchrony. On the other hand, the studies of attachment contradict themselves as harlows emphasis on the importance of contact comfort goes against social learning theory - which prioritises food. Schaffer and Emerson also noted that a baby’s primary attachment would still become the mother, even if others were feeding them. Therefore, we can’t come to a definitive answer for our attachment.
