These findings do not support the role of the internal working model being important in the development of childhood and adult relationships, casting doubt on the emphasis placed on this concept by developmental psychologists such as Bowlby
There are methodological issues with assessing attachment type retrospectively, as recollections from years gone by are likely to be impaired and any answers provided may lack accuracy due to deterioration which lowers the internal validity of findings
The internal working model is an unconscious framework, so individuals may not report honestly or even have an insight into their own template of expectations
Research into the impact of attachment on childhood and adult relationships have very set views on the outcomes for future behaviour, presenting a deterministic view of behaviour
Not all psychologists prescribe to deterministic views, and many would argue that humans have free will and the ability to overcome negative childhood experiences and go on to form happy and healthy adult relationships
