Green (1994) Humans and Monkeys are similar in that they have the same brain structure.

Harlow's research has important practical implications to childcare in that it recognises child’s physical needs alone are not sufficient for adequate development.

Results can't be generalised to humans. Do these animals/studies really reflect the emotional connections/interactions of humans?

Gosling experiment. Hatched with mother or incubator. Once goslings hatch they follow the first thing they saw that moved - which was Lorenz.

suggests that organisms have a biological propensity to form attachments to one single subject.

supports the view that having a biological basis for an attachment is adaptive as it promotes survival.

8 rhesus monkeys, caged from infancy with wire mesh food dispensing and cloth-covered surrogate mothers. measured the time that monkeys spent with each surrogate mother and the amount of time that they cried for their biological mother.

Findings - separated infant rhesus monkeys would show attachment behaviours towards a cloth-covered surrogate mother rather than a food-dispensing surrogate mother. Monkeys in isolation with the surrogate mothers all displayed dysfunctional adult behaviour,

Suggests that food is not as crucial as comfort when forming a bond.

The longevity of the goslings’ bond with Lorenz would support the view that early attachment experiences do predict future bonds.

Suggests early attachment experiences predict long-term social development
