Evaluation of Bowlby's evolutionary theory
Geese- Konrad Lorenz
Found that if he was the first thing the geese saw when they hatched then
they would follow him around (imprint on him)
Also, if the geese didn't see anyone within the first 24 hours they didn't
imprint on anyone.
This supports the critical period.
When the critical period is generalised to humans it is called the sensitive
period as humans can form attachments after a much longer time, 18 months
2 ½ years.
The continuity hypothesis (later development) suggests that individuals, who
are securely attached, continue to be socially and emotionally stable. The
secure attachment is the key to those later traits.
Kagan's temperament hypothesis can also explain the correlation. A trusting
and friendly personality, inherited through genes, could be the main factor
which influences attachment type and later development.
This alternative explanation for the trend doesn't support Bowlby's theory.
The idea that you have one main attachment which is to your mother.
Other researchers have questioned Bowlby's assumption that fathers do not
exert as much influence on their child's development as the mother does.
Research has shown that the quality of attachment to a father can influence
later development, for example, you are more likely to become a criminal if
you don't have a strong attachment to your father.
