What research is there to support the link between attachment and later development?
Fearon and Roisman: reviewed evidence and concluded that early attachment constantly predicts emotional wellbeing and parental relationships
Conveys that secure attachment -> advantages for future development and disinhibited attachment -> seriously disadvantages children
Why do retrospective studies weaken the validity of the influence of attachment?
Most research isn't longitudinal - researchers identify adolescent/adult participants' attachment types from asking them questions about their relationships with their parents
Relies on honesty and accurateperception of ppts
Hard to know whether it is adult or early attachment that is being assessed
Means measures of early attachment may be confounded with other factors - making them meaningless
How is the influence of early attachment on future relationships guilty of determinism?
Theory suggests that insecurely-attached children are doomed to struggle with later relationships, implying a lack of free will and self-fulfilling prophecies may occur
Other research suggests that insecurely-attached children can go on to experience happy and fulfilling relationships - and that attachment types are not the only factor that affect relationships (biological, innate personality factors)
Suggests attachment isn't as strongly linked to relationship development as thought
