1. John Bowlby Attachment Theory
By: http://studiousguy.com/
The origins of attachment theory: John Bowlby and
Mary Ainsworth.
Bretherton, Inge
Developmental Psychology, Vol 28(5), Sep 1992, 759-775.
Its developmental history begins in the 1930s, with Bowlby's
growing interest in the link between maternal loss or deprivation
and later personality development and with Ainsworth's interest in
security theory. Although Bowlby's and Ainsworth's collaboration
began in 1950, it entered its most creative phase much later, after
Bowlby had formulated an initial blueprint of attachment theory,
drawing on ethology, control systems theory, and psychoanalytic
thinking, and after Ainsworth had visited Uganda, where she
conducted the 1st empirical study of infant–mother attachment
patterns. This article summarizes Bowlby's and Ainsworth's
separate and joint contributions to attachment theory but also
touches on other theorists and researchers whose work
influenced them or was influenced by them. The article then
highlights some of the major new fronts along which attachment
theory is currently advancing. The article ends with some
speculations on the future potential of the theory.
Attachment theory is based on the joint work of J. Bowlby (1907–
1991) and M. S. Ainsworth (1913–)

2. Background
John Mostyn Bowlby was born in London to an upper-middle-class
family. He was the fourth of six children and was raised by a nanny in
traditional British fashion of his class. His father, Sir Anthony Bowlby,
first Baronet Bowlby, was surgeon to the King's Household, but with a
tragic history; at age five, his own father (John's grandfather) had been
killed while serving as a war correspondent in the Anglo-Chinese Opium
War. Normally, John saw his mother only one hour a day after teatime,
though during the summer she was more available. She had thought
that spoiling her children was dangerous, so that attention and
affection was the opposite of what was required with a child. When

3. Bowlby was almost four years old, his beloved nanny, who was actually
his primary caretaker in his early years, left the family. Later, he was to
describe this as tragic as the loss of a mother.
At the age of seven, he was sent off to boarding school. His later work,
for example Separation: Anxiety and Anger, revealed that he regarded
it as a terrible time for him. Because of such experiences as a child, he
displayed an unusual sensitivity to children’s suffering throughout his
life.
He died September 2, 1990 at his summer home in Isle of Skye,
Scotland. He had married Ursula Longstaff, herself the daughter of a
surgeon, on April 16, 1938, and they had four children, including (Sir)
Richard Bowlby, who succeeded his uncle as third Baronet Bowlby and
is active in continuing his father's work.
Attachment Theory

4. Attachment theory is a concept in developmental psychology that
concerns the importance of "attachment" in regards to personal
development. Specifically, it makes the claim that the ability for an
individual to form an emotional and physical "attachment" to another
person gives a sense of stability and security necessary to take risks,
branch out, and grow and develop as a personality. Naturally,
attachment theory is a broad idea with many expressions, and the best
understanding of it can be had by looking at several of those
expressions in turn.

5. Stages of Attachment
The babies were visited monthly for approximately one year, their
interactions with their carers were observed, and carers were
interviewed. A diary was kept by the mother to examine evidence for
the development of an attachment. Three measures were recorded:

6.  Stranger Anxiety - response to arrival of a stranger.
 Separation Anxiety - distress level when separated from carer,
degree of comfort needed on return.
 Social Referencing - degree that child looks at carer to check how
they should respond to something new (secure base).
They discovered that baby's attachments develop in the following
sequence:
Asocial (0 - 6 weeks)
Very young infants are asocial in that many kinds of stimuli, both social
and non-social, produce a favourable reaction, such as a smile.
Indiscriminate Attachments (6 weeks to 7 months)
Infants indiscriminately enjoy human company and most babies
respond equally to any caregiver. They get upset when an individual
ceases to interact with them.
From 3 months infants smile more at familiar faces and can be easily
comfortable by a regular caregiver.
Specific Attachment (7 - 9 months)
Special preference for a single attachment figure. The baby looks to
particular people for security, comfort and protection. It shows fear of
strangers (stranger fear) and unhappiness when separated from a
special person (separation anxiety).
Some babies show stranger fear and separation anxiety much more
frequently and intensely than others, but nevertheless they are seen as
evidence that the baby has formed an attachment. This has usually
developed by one year of age.
Multiple Attachment (10 months and onwards)
The baby becomes increasingly independent and forms several
attachments. By 18 months the majority of infants have form multiple
attachments.

7. The results of the study indicated that attachments were most likely to
form with those who responded accurately to the baby's signals, not
the person they spent more time with. Schaffer and Emerson called
this sensitive responsiveness.
Intensely attached infants had mothers who responded quickly to their
demands and, interacted with their child Infants who were weakly
attached had mothers who failed to interact.
Many of the babies had several attachments by 10 months old,
including attachments to mothers, fathers, grandparents, siblings and
neighbors. The mother was the main attachment figure for about half
of the children at 18 months old and the father for most of the others.
The most important fact in forming attachments is not who feeds and
changes the child but who plays and communicates with him or her.
Therefore, responsiveness appeared to be the key to attachment.
