Harlow’s findings revealed that separated infant rhesus monkeys would show attachment behaviours towards a cloth-covered surrogate mother when frightened, rather than a food-dispensing surrogate mother. Harlow measured the amount time that monkeys spent with each surrogate mother and the amount time that they cried for their biological mother. Harlow conducted research with 8 rhesus monkeys which were caged from infancy with wire mesh food dispensing and cloth-covered surrogate mothers, to investigate which of the two alternatives would have more attachment behaviours directed towards it. This would explain why goslings imprint after a matter of minutes due to their increased mobility human babies are born immobile and therefore there is less call for them to form an attachment straight away, and so, this develops later (8-9 months). It supports the view that having a biological basis for an attachment is adaptive as it promotes survival. Once goslings had hatched they proceeded to follow the first moving object that they saw between 13 & 16 hours after hatching in this case, Lorenz. Lorenz conducted an experiment in which goslings were hatched either with their mother or in an incubator. Lorenz’s research suggests that organisms have a biological propensity to form attachments to one single subject. Of the most well-known animal studies were conducted by Konrad Lorenz and Harry Which used animal subjects to investigate early life experiences and theĪbility for organisms to form attachments contributed significantly to the
