avoidant children are not interested in contact and show no difference when either separated or reunited with their caregivers. anxious-ambivalent children want attention from their caregiver, experience fear when separated and are not willing to experience new situations. secure and anxious-ambivalent attachments are advantageous in the social world as staying with a caregiver allows them to explore and develop while being provided for (Bowlby 1965 as cited inMitchell, Ziegler, and Mitchell, 2013).
Regardless of the type of attachment a person has, it helps them to develop and grow into an adult with different cognitive mechanisms to navigate the social world. This can be assumed by the evidence of children who do not have attachments e.g. orphans. Due to not having attachments, it causes problems in the social world as they have not learned socially acceptable behaviour via primary socialisation, do not have fully developed brains and do not have all their cognitive mechanisms to an acceptable range e.g. delay in speech and language (Nelson 2007 as cited in Martin, Carlson, and Buskist,
