DEVELOPMENTAL PSYCHOLOGY -
Explanations of atttachment
Learning theory
Classical
UCS produces UCR (before conditioning
CS produces CR (after conditioning)
Food is UCS, produces pleasure (UCR). Feeder (NS) becomes
associated with food (UCS) and pleasure (CR) is associated with
feeder.
Association between individual
and sense of pleasure is
attachment bond
Operant
Reinforcement + Punishment
Dollard & Miller (1950)
Hungry infant has drive to reduce that discomfort. Infant is
fed, producing pleasure (reward). Food becomes primary
reinforce. Supplier of food becomes secondary reinforce.
Attachment occurs because child
seeks person who can supply the
reward.
Lacks validity -
studies on animals -
oversimplified.
However, behaviourists believe we are
no different to animals.
Evaluation
Strengths
Provides an adequate
explanation of how
attachments form. We
do learn through
association and
reinforcement but food
may not be the main
reinforcer.
Weaknessess
Contact comfort is more important than food.
Harlow's monkeys (1959).
2 wire mothers, 1
with feeding bottle
and 1 covered in
cloth.
Monkeys spent most time
with cloth covered mother
and would cling to it when
frightened.
Human studies also challenge the
importance of food for
attachment
Schaffer and Emerson (1964).
60 babies from working-class homes in Glasgow.
Infants were most attached to the person
who was most responsive + interactive, not
the one who fed them.
Bowlby's theory (1969)
Children have innate drive to become
attached to caregiver. Adaptive because
they increase likelihood of survival.
Sensitive period
2nd quarter of the first year,
as months pass it becomes
increasingly difficult to form
attachments.
Caregiving is adaptive
Social releasers e.g. smiling
and crying elicit caregiving
A secure base
Attachment acts as a secure base
from while child explores and safe
haven to return to.
Monotropy and hierarchy
Primary attachment is monotropy.
Infants become most attached to
person who person who responds
most sensitively to infant's social
releasers
The primary attachment figure provides the main foundation for
emotional development, self esteem and later relationships.
Internal working model
Cluster of concepts about relationships
and what to expect from others.
The continuity hypothesis
There is a link between early attachment
behaviour and later emotional behaviour
Evaluation
Strengths
Research by Lorenz supports
imprinting (goslings followed 1st
moving object)
Sensitive period
Hodges and Tizard found that children who hadn't
formed attachments later had difficulties with peers.
Universality
If attachment did evolve, then it would be found in all cultures.
Tronick et al. (1992) studied an African tribe which lived in
extended family groups and found that the infants still
showed 1 primary attachment at 6 months.
Monotropy and hierarchy
Supported by Tronick et al.
Schaffer and Emerson also found this. They also
found little relationship between time spent and
attachment - suggests quality is most important.
Fathers are
important: When
monkeys only stayed
with their mothers,
they were socially
abnormal (Harlow).
Caregiver sensitivity
Schaffer & Emerson observed that
strongly attached infants had mothers
who responded quickly.
Harlow: wire
mother left
monkeys
maladjusted.
Carlson (1998) found that
insensitive caregiving was
associated with
disorganised attachment.
The continuity hypothesis
The Minnesota longitudinal study fond
continuity between early attachment and
later emotional / social behaviour.
Limitations
Multiple attachments
Grossmann & Grossmann (1991) did research
on infant-father attachment and suggest that
fathers have a key role in social development.
Alternative explanation - the temperament hypothesis
That certain personality /
temperamental characteristics of
the infant shape a mother's
responsiveness.
Born with it
Thomas & Chess found:
easy, difficult and easy
to warm up.
Belsky & Rovinne support this hypothesis
Infants who were
calmer and less
anxious were more
likely to be securely
attached.
