In the first chapter on attachment theory, I explained the four characteristic of attachment: safe haven, separation distress, secure proximity maintenance and safe base. Based on how well the caregiver meets each characteristic, the baby and his/her caregiver will form a different attachment style.
In a famous experient titled the “Stranger situation” psychologists Mary Aninsworth (expanding on work done by Bowlby) observed children between the age of 12 to 18 months. She was interested in their response at being left alone and then reunited with their mothers. The results led her to 3 major attachment styles. In 1986, researches Main and Solomon added a forth attachment style. A number of studies since then have confirmed that the attachment style that developed in a child’s early years of life will determine their future relationships and connections with other human beings for years to come.
The four attachment styles are: secure, ambivalent, avoidant and disorganized.
