adults base parenting style of own internal working model, attachment types can be passed down generations
Bailey et al:
studied attachment of 99 mothers to their babies + own mothers
mother infant through strange situation + mothers attachment through adult attachment interview
majority has same attachment to both mothers + babies
EVALUTION: research support
review (Fearon + Roisman) found early attachment predicts later attachment + emotional wellbeing
strength of connection between early + later attachment depends on type e.g insecure avoidant = mild disadvantages, disorganised = linked to developments of mental disorders
supports notion of secure attachment advantages + disorganised correlates to serious disadvantages
EVALUATION: problems with methodology:
most research isnt longitudinal ( dont revisit same person), instead ask questions about relationships with parents to identify type
2 validity issues: relies on honesty + accuracy (social desirability bias) + difficult to know what is being assessed (childhood or adult)
methodology may be confounded with other factors = less meaningful
EVALUATION: reductionism (CVs + alternative explanation):
mcCarthy assessed infancy attachment, assessment of childhood attachment is valid - however quality + later development can be affected by other variables e.g traumatic incidents
psychological approaches suggest alternative approaches e.g genetically influenced personality
not sure if early attachment or other factors influence later developments
