Rudolph Schaffer and Peggy Emerson (1964) conducted a longitudinal study on 60 babies, observing them at monthly intervals for the first 18 months of life
The study focused on three measures:
Stranger Anxiety: response to the arrival of a stranger
Separation Anxiety: distress level when separated from the carer and degree of comfort needed upon return
Social Referencing: degree to which the child looks at the carer to check how to respond to something new (secure base)
Stages of attachment development:
Asocial Stage (0-6 weeks): infants are asocial and react favorably to various stimuli
Indiscriminate Attachments (6 weeks to 7 months): infants enjoy human company and respond equally to any caregiver, getting upset when interaction ceases
Specific Attachment (7-9 months): preference for a single attachment figure, showing fear of strangers and unhappiness when separated
Multiple Attachment (10 months and onwards): infants become independent and form several attachments, with most infants having multiple attachments by 18 months
Attachments are most likely to form with those who respond accurately to the baby's signals, not necessarily the person they spend the most time with (sensitive responsiveness)
Factors affecting attachment:
Prematurity: premature babies in incubators may struggle with the attachment process
Disability: parents may find it harder to attach to a baby with a disability, impacting attachment formation
Post-natal depression (PND): long-lasting PND can affect a mother's ability to bond with her baby
Challenges to attachment formation:
Emotional unavailability: parents' issues with alcohol, drug abuse, illness, or struggling with their role
Separation: parents' separation from the baby due to illness, bereavement, or divorce can impact attachment and a baby's sense of identity
Foster care/adoption: inconsistency of caregivers in the care system can affect attachments and a child's sense of identity
