    • aim
      Ainsworth & bell
      to produce a method of assessing the quality of attachments & to investigate whether there are individual differences in attachment
    • procedure
      controlled observation, 100 middle class American infants (12-18 months old) and their mothers
      seven 3-minuete episodes = mother leaves rom, re-enters room, stranger enters and leaves room
      behaviours observed - separation anxiety , willingness to explore , stranger anxiety , reunion behaviour
    • findings
      3 types of attachment found
      type A - insecure avoidant
      type B - secure
      type C - insecure resistant
    • type A - insecure avoidant
      22% , indifferent to mother , no separation anxiety or joy on reunion , no preference for mother over stranger, doesn't use mother as safe base
    • type B - secure
      66%, separation anxiety, joy on reunion, preference for mother over stranger, uses mother as safe base
    • type C- insecure resistant
      12%, extreme distress on separation, clingy, not comforted easily
    • conclusion
      there are individual difference in attachment, most american children are securely attached, appears to be association between mothers behaviour and attachment type, suggesting mothers behaviour determines attachment type
    • evaluation - reliability
      test-retest reliability = study in Germany found 78% children were classified the same at 1 and 6 years , when changes did occur they were linked to changes in family structure - attachment type is consistent over time
    • evaluation - population validity
      original study used middle class infants, may not be able to generalise to other social classes , study is ethnocentric as all P's were American - may not generalise to other cultures , childcare and attachment may differ around the world
    • evaluation - imposed etic approach
      was designed for measuring attachment in american infants, therefore may not be valid tool for assessing attachment in other cultures - but has been used cross-culturally = use of technique developed in one culture to study another - issue because different cultures have different norms , lacks cross-cultural validity
    • evaluation - internal validity
      demand characteristics - mother aware shes being observed , knows part of the aim , might interact with baby more than normal
      social desirability bias - wants to be seen as a good mother
      experience with previous separation - supported by research about Japanese babies
      temperament hypothesis - some babies born more independent, friendly... behaviour in could be due to innate personality not attachment type
    • evaluation - ethical issues
      no protection from physical harm, babies get upset which is upsetting for mother
      mother may feel unconfutable / embarrassed
