A strong, lasting emotional bond formed between a baby and their main caregiver
Features of attachment
Safe Base- children turning back to caregiver when scared/anxious.
Separation Anxiety- When children become distressed when they are separated from their attachment figure.
Stranger Anxiety- When children display distress in the presence of unfamiliar people, and instead prefer the company of their attachment figure.
Strengths of Longitudanal Studies
First, longitudinal studies enable us to get deeper insights into behaviour by seeing how behaviour changes over time.
Second, longitudinal studies give us insights into how early experiences shapes behaviour.
Third, longitudinal studies lead to more reliable results, because researchers can establish whether the participants’ behaviours are consistent over time.
What is meant by Attrition?
Attrition occurs when there is a loss of participants across the course of a study.
Attachment Stages:
Pre-Attachment Stage- first 3 months, no preference for any adult.
Indiscriminate Attachment Stage- 3-7 months, prefer familiar people, not one person in particular.
discriminate Attachment Stage- 7-9 months, preference to specific person.
Multiple Attachment Stage- 9 months onwards, attachment with people other than main caregiver.
Schaffer and Emerson (1969)
Longitudinal and Naturalistic observational study
60 babies from birth to 18 months
observed with caregivers to see separation anxiety + stranger anxiety
interviews conducted with family members
RESULTS:
Babies formed stronger attachments if caregivers displayed high sensitive responsiveness.
Evidence for the four stages of attachment.
87% of babies formed attachments with 2+ caregivers.
31% of babies formed attachment with 5+ caregivers
main attachment figure not always main caregiver
Strengths and Weaknesses to Schaffer and Emerson (1969)
STRENGTH: naturalistic observational study = more ecological validity + generalise behaviours in everyday life
WEAKNESSES:observer bias: (tendency for researchers to see what expect when conducting observation)Interview technique: socially desirable bias
,Reciprocity
The infant and caregiver take turns in an interaction, so that they respond to each others reactions
Interactional synchrony
caregivers and babies perform similar actions in time with each other
There are two studies that support the role of interactional synchrony and reciprocity in strengthening attachments...
Condon and Sander demonstrated that caregivers and infants display interactional synchrony and reciprocity
observed movements made by babies when with their mothers
babies actions timed in time with mothers speech
Isabella (et al) also doing positive correlation between interactional synchrony and strength attachment bond
The Learning Theory Of Attachment
Attachment is learnt through experience of being fed by care givers.
The reason babies form attachments is because caregivers feed them.
learn through operant + classical conditioning
Classical conditioning on Attachment
baby --> food = unconditional stimulus
baby --> caregiver = neutral stimulus
if the caregiver feeds the baby the caregiver will become a conditioned stimulus and the baby will produce a happy conditioned response.
Operant reinforcement on Attachment
Positive Reinforcement = the action of staying near the caregiver, babies learning that they get food when they stay near their caregiver.
Negative Reinforcement = the action of staying near the caregiver, babies learning that they can reduce hunger by staying near the caregiver.
Harlow (1959)
AIM: Test Learning Theory of Attachment by investigating whether monkeys choose comfort or food:
laboratory experiment
8 baby monkeys: 2 control groups
one: wire-mum, towel-mum (milk)
two: wire-mum (milk), towel-mum
DV: amount of time spend with either mother
IV: type of mother
RESULTS: Doesn't support Learning Theory of Attachment
suggests attachments are driven by comfort
Harlow Evaluation:
STRENGTHS:
conducted laboratory experiment = control extraneous variables e.g. milk given, living conditions
WEAKNESSES:
two types of fake mother had different heads = act as confounding variable
conducted on monkeys = lack generalisability (not representative)
unethical = distressed monkeys, couldn't consent
STRENGTHS of Learning Theory and Attachment
support from observation from Dollard + Miller:
observed babies and counted times fed in 1 year = 2000+ plus
suggesting Learning Theory of Attachment is true
WEAKNESSES of Learning Theory of Attachment
Harlow found that baby monkeys choose comfort over food
Babies raised in communal environments (Israel) by foster mums called metapelets don’t form attachments to their foster mums
Bowlby- Attachment
According to Bowlby’s monotropic theory, we have become biologically pre-programmed to need to form attachments to our caregivers through the process of evolution
Social Releasers
behaviours that babies perform to attract the attention of their caregivers
Caregiver biologically-programmed to help when social releasers cued
Crying, smiling, crawling and following are all social releasers.
Babies are biologically pre-programmed to perform social releasers.
Monotropic
Mono = one
Tropic = attachment
Bowlby stated that babies form one, unique attachment to one caregiver
The Critical Theory
Bowlby's theory:
First 2 1/2 years of babies life to form attachment
The Internal Working Model
The internal working model is a schema built from a child’s relationship with its main attachment figure, that guides the child's expectations and beliefs about future relationships.
Lorenz + imprinting
Lorenz conducted an experiment on geese to see how they form attachments
A control group of baby geese were hatched normally in the presence of their mother. An experimental control group were hatched in the presence of Lorenz.
The baby geese attached to the first thing they saw suggesting the attachment was biologically pre-programmed
WEAKNESSES Lorenz
A first weakness of his study is that the results were not completely replicated in later studies.
For instance, in Guiton’s research into imprinting baby chicks, he found that attachments were reversible and weren’t monotropic .
A second weakness of his study is that the results might not generalise to humans.
support for Bowlby's monotropic Theory (metapeletes):
Observations of metapeletes in Israel support the idea that attachments are formed to the main caregiver who provides emotional support and comfort, and that attachments are monotropic .
Bowlby's theory: real-world application:
positive: longer visiting hours for hospitals and longer parental leave.
negative: made mothers feel guilty for not staying at home and looking after children
Bowlbys' Maternal deprivation Theory
When children are deprived of an attachment figure during the critical period, they suffer psychological damage.
Psychological damage caused by deprivation is long-lasting and irreversible.
Consequences of Deprivation
Impairedemotional development, such as lashing out and showing signs of not caring for other
Impaired behavioural development, such as delinquency like fighting and fraud.
Impaired cognitive development, such as low IQ and poor language skills
PDD MODEL
three stages of short term detachment from main caregiver:
protest
despair
detachment
Little John Case Study
conducted by Bowlby and Robertson
Little John was separated from his mother and placed in a nursery for 9 days.
case study
Little John experienced all 3 stages
It was concluded that the effects of the separation were long-term
Bowlby's 44 Thieves study
compared 44 thieves to a control group of 44 non-criminals
conducted interviews
Bowlby asked the children to describe their childhood, focussing particularly on whether they had been separated from their attachment figure.
50% thieves - maternal deprivation in childhood
5% control group - maternal deprivation
32% classed as affectionless psychopaths
86% of affectionless psychopaths experienced maternal deprivation
Limitations of Bowlbys' 44 thieves study
interviews unreliable and lack objectivity (e.g. leading questions, memory fogged)
participants influenced by investigator effects (respond to demand characteristics)
Lacked control over extraneous variables as natural experiment
Limitations of Bowlby's Maternal Deprivation Theory
bowlby believed effects are irreversible
Jarmila Koluchova proved differently:
When the twins were found at the age of 7, they had experienced severe deprivation.
With the help of their adopted parents, the effects of the twins’ deprivation were reversed.
By the time they were adults, both twins were above average intelligence, had good jobs, and were in happy relationships.
Limitation of Bowlby Maternal Deprivation Theory- confounding variables
There are many other confounding variables that could cause any psychological damage to the children.
Establishing a causal relationship between deprivation and psychological damage is difficult.
Limitations of Maternal Deprivation Theory: Privation vs Deprivation
Michael Rutter criticised Bowlby’s theory because he confused deprivation with privation
privation: child never forms attachment to caregiver
more sever long-term effects
Hodges and Tizzard
natural experiment
65 children
4 groups:
children who were adopted early
returned to biological parents
remained in institution
control group who had not bee institutionalised
FINDINGS:
The children who were adopted early didn’t develop psychological damage.
The findings suggest that the effects of privation are irreversible.
The children who experienced privation and remained in the institution, or were returned to their biological parents, experienced impaired emotional development.
Rutter Romanian Children
naturalist, longitudinal study
111 Romanian children adopted in british homes
compared to 53 British orphans
found that Romanian children who were adopted after 6months had long-lasting effects of privation
Romanian children who were adopted before 6months reversed long-lasting effects of privation
Romanian children had more severeemotional impairment due to conditions of institutions of Romania (more neglection etc)
Limitations of Institutionalisation
Families might have displayed social desirability bias meaning a possible underestimation of the negative effects of privation.
There is oftenattrition in longitudinal studies meaning a possible underestimation of the negative effects of privation.
Attachment styles:
children displaying different behaviours + feelings towards caregivers
