A strength of Bowlby's theory?

-Research support for the concept of the internal working model -Bailey assessed attachment relationships in 99 mothers and their 1 year old babies. Measured the mothers' attachment to their own primary attachment figures (parents) -Researchers also assessed the attachment quality of their babies. Found that mothers with poor attachment to their own primary attachment figures were more likely to have poorly attached babies -Supports Bowlby's idea that mothers' ability to form attachments to their babies is influence by their own internal working model, which is due to their own early attachment experiences
