Shaffer and Emerson found that many formedone attachment at first but a significantminority formed multiple at the same time
Athough its suggests that the first attachment has a strong influence on the baby's later development it may mean stronger not different in terms of the quality of therebabies other attachments
For example family members provide the samequality ie emotionalsupport
may incorrect in saying that the primary attachment figure has a uniquequality and important
STRENGTH:
Evidence supporting the role of social releasers
Cutebabybehaviours are designed to elicitinteraction from caregivers
Brazelton et al 1975 observed babies trigger interactions with adults using socialreleasers
Researchers instructed the primary attachment figures to ignore babies socialreleasers
Babies became increasinglydistressed and some eventually curled up and lay motionless
illustrates the role of social releasers in emotionaldevelopment suggests that they are important in the process of attachmentdevelopment
STRENGTH
Support for the internalworkingmodel
Predicts patterns of attachment will be passed from onegeneration to the next
Bailey et al 2007 assessed attachmentrelationships in 99 mothers and their 1 year old babies
Measured mothersattachment to their own primaryattachment figures ie their parents
Assessed attachment quality of the babies
Found mothers with poorattachment to their own primary attachment figures were more likely to have poorlyattachedbabies
Supports idea that mothersability to form attachments to their babies is influenced by their internalworkingmodels
