A weakness of of Bowlby's theory?

-A lack of reserach support for monotropy which Bowlby was said to be crucially important -Schaffer and Emerson found that although most babies did attach to one person at first, a signifiant minority formed multiple attachments at the same time. -Although the first attachment does appear to have a strong influence on later behaviour, this may simply mean its strong, no different in quality from the child's other attachment. Eg: other attachments to family members provide all the same key qualities (emotional support, safe base) -Means that Bowlby may be incorrect with his assertion that there is a unqiue quality and importance to the child's first primary attachment figure
