what was the method of Schaffer and Emmerson's study?
60 babies from working class families in Glasgow were observed
mothers and babies were visited once a month for the first year and then again at 18 months
they asked mothers questions about how the babies reacted in 7 everyday separations - separation anxiety
they assessed how babies reacted to unfamilliar adults - stranger anxiety
what were the findings of Schaffer and Emmerson?
between 25-32 weeks 50% of babies showed separation anxiety towards mother
this specific attachment was with the caregiver who was most sensitive to infant signals.
by 40 weeks 80% had a specific attachment and 30% had multiple
what are the stages of attachment?
Asocial: birth- 8 weeks
Indiscriminate: 2-7 months
specific attachment: 7-12 months
multiple attachments: 1 year onward
what are features of the Asocial stage?
behaviour between humans and non human objects are very similar
infants can recognise specific faces
happier in the presence of humans
will smile at anyone
prefer familiar individuals
what are features of the indiscriminate stage?
recognise and prefer familiar people
smile more at familiar faces
preference for people rather than objects
will accept comfort from ANYONE - no stranger anxiety
what are features of the specific attachment stage?
distinct protest when a particular person leaves - separation anxiety
happiness when comforted by that specific person - specific attachment
will show stranger anxiety
specific attachment isn't just about who spends the most time with them
what are features of the multiple attachment stage?
multiple attachments formed based on their consistent relationships
within 1 month of becoming attached 29% of infants had multiple attachments
within 6 months this had risen to 78%
what are the strengths of the stages of attachment?
there's good external validity in the study
it has real world application
why is there good external validity?
most observations done by parents during normal activities - highly likely that the ppts behaved normally
HOWEVER - mothers may not have reported some things - systematic bias
what is the real world application?
in the early stages babies can be comforted by any skilled adults but if a child starts day care during the stage of specific attachments care from unfamiliar adults may cause distress
why is the biased sample a weakness?
all ppts from the same district
working class population
sample from the 1960s - parenting has changed
now more mothers work
why were there problems studying the asocial stage?
babies have poor coordination and are immobile. therefore difficult to make judgments from observation - low reliability
what are the cultural variations? (weakness)
individualistic culture - western cultures value independence
