Bowlby believed attachment was an innate system that gives us survival advantage. Attachment evolved as a mechanism to keep young animals safe by ensuring they stay close to adult caregivers.
Monotropy
Bowlby placed great emphasis on a child's attachment to one particular caregiver - monotropic. He believed the child's attachment to this one caregiver is different and more important than others. Bowlby believed the more time a baby spent with the primary attachment caregiver the better.
the law of continuity - the more constant and predictable a child’s care the better their quality of attachment.
the law of accumulated separation - the effects of every separation from the mother add up and the safest dose is therefore a zero dose
Social releasers & the critical period 1/2
Bowlby suggested that babies are born with a set of innate cute behaviours like smiling, cooing & gripping that encourage attention from adults. These actions activate adult social interaction and make an adult attach to the baby. Bowlby recognised attachment was a reciprocal process. Mother and baby are hand-wired to become attached.
Social releasers & the critical period 2/2
The interplay between baby and adult attachment systems gradually builds the relationship between baby & caregiver, beginning in early weeks of life. Bowlby proposed there’s a critical period around 6 months when the infants attachment system is active : viewed more as a sensitive period. A child is maximally sensitive at 6 months, possibly extending to the age of 2. If an attachment isn't formed in this time, the child will find it much harder to form one later.
Internal Working Model
Bowlby proposed that a child forms a mental representation of their relationship with their primary caregiver ; internal working model. It serves as a blueprint for all future relationships. It affects the child's later ability to be a parent themselves. People tend to base their parenting behaviour on their own experiences of being parented. This explans why children from functional families tend to have similar families themselves.
