Research on Bowlby's evolutionary theory
Konrad Lorenz (1935):
He studied the behaviour of geese who are likely to imprint on the first moving object the see-
following their mother wherever she goes.
He divided a group of chicks in two- left one group with their natural mother and the other eggs
were kept in an incubator. When the eggs in the incubator hatched, the first living/ moving thing they
saw was Lorenz, so started following him everywhere he went, and the same with the natural
mother. After a while, he marked them to see which ones were which and placed them together in
the same group with their natural mother. They quickly divided themselves up and followed whoever
was their `mother'.
How is this related to the evolutionary theory?
A young animal is more likely to be safe from predators, fed and learn how to find food. It is more
likely to survive- which is what the evolutionary theory is all about- Inherited behaviours that
promote reproduction are naturally selected.
Lamb (1982)- Study on monotropy
Studied the relationships and attachments infants had with many people like fathers,
grandparents and siblings. He found that different attachments served for different purposes
rather than being a hierarchy.
