These Maternal deprivation A-Level Psychology revision notes explain Bowlby’s claim that prolonged disruption of an infant’s relationship with a mother or permanent mother substitute may damage intellectual, emotional and social development. Crucially, separation is not automatically deprivation: harmful deprivation occurs when suitable emotional care is unavailable. You will distinguish deprivation from privation, ordinary separation and institutionalisation before evaluating Bowlby’s evidence, alternative explanations, recovery research and the practical impact of the theory.
The planned lesson focuses on explaining Bowlby’s theory, distinguishing forms of disrupted attachment and evaluating maternal deprivation as an explanation of developmental difficulties.

Revision Notes 📚
What is maternal deprivation?
Maternal deprivation is the prolonged loss or disruption of an infant’s relationship with their mother or permanent mother substitute when suitable emotional care is not available.
Bowlby argued that a young child needs a warm, intimate and continuous relationship with one principal attachment figure.
A serious or prolonged disruption to this relationship could affect:
Intellectual development.
Emotional development.
Social relationships.
Empathy and guilt.
Behaviour.
Later mental health.
The phrase mother figure does not have to mean the biological mother.
It may refer to:
A father.
An adoptive parent.
A foster carer.
A grandparent.
Another stable, responsive caregiver.
The key factor is the continuity and emotional quality of care rather than the caregiver’s biological relationship or gender.
Maternal deprivation and monotropy
Bowlby’s theory of maternal deprivation developed from the importance of a primary attachment figure.
According to monotropy:
Infants can form several attachments.
One attachment usually has special psychological importance.
This primary attachment provides security.
It contributes to the child’s internal working model.
Prolonged disruption may therefore have particularly serious consequences.
The deprivation hypothesis assumes that the primary attachment is not easily replaced by occasional or emotionally unresponsive care.
Bowlby’s central claim
Bowlby proposed that:
A young child should experience a warm, intimate and continuous relationship with a mother or permanent mother substitute.
When that relationship is absent or seriously disrupted, developmental difficulties may follow.
The basic sequence is:
Important attachment forms → prolonged separation occurs → adequate substitute care is unavailable → deprivation is experienced → development may be impaired
Separation is not automatically deprivation
This is one of the most important distinctions in the topic.
Separation means that the child is physically apart from the attachment figure.
Deprivation means that the child loses the emotional care normally provided by that relationship.
A child may be separated without being deprived.
For example, a child may stay in hospital while:
A parent visits regularly.
A familiar relative provides care.
Staff offer consistent and responsive emotional support.
Contact with the attachment figure is maintained.
The child is physically separated but may still receive sufficient emotional care.
In contrast, deprivation is more likely if:
The separation is prolonged.
Contact is limited.
Caregivers change repeatedly.
Nobody provides stable affection.
The child cannot form a substitute attachment.
Existing attachment needs are consistently unmet.
Quality of substitute care
The quality of substitute care determines whether separation becomes deprivation.
Suitable substitute care should be:
Stable.
Responsive.
Emotionally warm.
Consistent.
Sensitive to the child’s needs.
Available during distress.
A separation may be less harmful when the child forms a secure relationship with another caregiver.
A child can therefore be separated from their biological mother without experiencing maternal deprivation.
Applying the distinction
Scenario A
A two-year-old child’s mother spends several weeks in hospital. The child stays with a familiar grandparent who provides stable, affectionate care.
This is separation, but it may not become deprivation because:
The substitute caregiver is familiar.
Emotional care remains available.
The child has a stable relationship.
The mother-child relationship can be maintained through contact.
Scenario B
A two-year-old child experiences repeated changes of caregiver over several months. No adult remains long enough to provide consistent comfort.
This situation is more likely to involve deprivation because:
The primary relationship has been disrupted.
Substitute care lacks continuity.
The child cannot rely on one stable caregiver.
Emotional needs may remain unmet.
The critical period
Bowlby’s critical period
Bowlby argued that the effects of deprivation are particularly serious during an early critical period.
He proposed that infants are maximally ready to form and maintain attachments during approximately the first two-and-a-half years of life.
The risk of harmful consequences may continue into the early childhood years, sometimes described as extending up to around five years.
During this early period:
The attachment system develops.
The child forms expectations about caregivers.
Emotional regulation develops.
Language and intellectual skills develop rapidly.
The internal working model begins to form.
Prolonged deprivation during this stage may therefore have wide-ranging consequences.
Why timing matters
According to Bowlby, the earlier and longer the deprivation, the greater the risk.
Possible influences include:
The child’s age when separation begins.
The duration of separation.
Whether an attachment had already formed.
The quality of substitute care.
Whether the child later receives stable care.
Whether separations are repeated.
The theory does not predict that every brief separation causes permanent damage.
Critical or sensitive period?
A strict critical period implies that development becomes impossible or permanently damaged once the period has passed.
A sensitive period is a time when development occurs most easily, although later recovery remains possible.
Evidence that some deprived children improve after receiving stable care suggests that a sensitive-period account may be more accurate.
A balanced conclusion is:
Early deprivation presents a significant developmental risk, but its consequences are not necessarily inevitable or irreversible.
Prolonged and accumulated separation
Prolonged separation
A long period without the attachment figure may disrupt the continuity of care.
The possible effect depends on whether another caregiver provides suitable emotional support.
A long separation with excellent substitute care may be less harmful than a shorter separation involving frightening or inconsistent care.
Accumulated separation
Bowlby also considered the possibility that several separations might accumulate.
For example:
Repeated hospital admissions.
Frequent changes of foster placement.
Regular movement between institutions.
A caregiver repeatedly leaving without predictable reunion.
Each separation may be short, but the combined disruption could reduce the child’s sense of security.
The child may learn that caregivers are:
Unavailable.
Unpredictable.
Temporary.
Difficult to trust.
Day care is not automatically deprivation
Regular childcare should not automatically be described as maternal deprivation.
A child attending day care may still experience:
A stable relationship at home.
Predictable daily reunions.
Consistent childcare staff.
Warm and responsive interaction.
Several meaningful attachments.
Maternal deprivation concerns serious disruption without adequate emotional care, not every period spent away from a parent.
Possible consequences of maternal deprivation
Bowlby proposed several possible developmental consequences.
These include:
Reduced intellectual development.
Emotional difficulties.
Affectionless psychopathy.
Delinquency.
Difficulties forming relationships.
Intellectual development
Bowlby suggested that prolonged deprivation could affect intellectual development.
Possible outcomes include:
Reduced intelligence quotient, or IQ.
Delayed language development.
Poorer educational progress.
Difficulties concentrating.
Below-average academic achievement.
The explanation is that children deprived of stable care may receive less:
Language interaction.
Cognitive stimulation.
Encouragement.
Sensitive support.
Opportunity for exploration.
However, low intellectual performance could also result from poor education, malnutrition or generally deprived surroundings rather than the loss of one attachment alone.
Emotional difficulties
Possible emotional consequences include:
Anxiety.
Low trust.
Emotional withdrawal.
Difficulty regulating distress.
Fear of abandonment.
Problems seeking or accepting comfort.
The child may develop an internal working model in which other people are viewed as unreliable.
Affectionless psychopathy
Bowlby used the historical term affectionless psychopathy to describe a pattern involving:
Lack of guilt.
Limited empathy.
Reduced concern for others.
Difficulty forming genuine affection.
Failure to develop close relationships.
This is not the same as a current clinical diagnosis.
Within Bowlby’s theory, a child who lacks a stable early relationship may fail to develop the emotional understanding needed for empathy and guilt.
Delinquency
Delinquency refers to antisocial or criminal behaviour committed by a young person.
Bowlby proposed that affectionless psychopathy could increase delinquency because a young person may:
Feel little guilt.
Show reduced empathy for victims.
Struggle to value relationships.
Be less affected by the emotional consequences of their actions.
However, delinquency has many possible causes, including:
Poverty.
Peer influence.
Family stress.
Education.
Social disadvantage.
Temperament.
Maternal deprivation should not be treated as the only explanation.
Difficulties forming relationships
A deprived child may develop expectations that:
Caregivers will leave.
Support is unreliable.
Closeness is unsafe.
Emotional needs will not be met.
These expectations may influence:
Friendships.
Relationships with teachers.
Romantic relationships.
Parenting behaviour.
This link can be explained through the internal working model and later relationships.
Not every child shows every effect
The theory proposes increased risk, not certainty.
Outcomes may depend on:
Length of deprivation.
Age at deprivation.
Quality of later care.
Child temperament.
Social support.
Educational opportunities.
Whether the child had formed an attachment previously.
Wider family and economic circumstances.
Separation, deprivation and privation
Separation
Separation is physical absence from the attachment figure.
It may be:
Brief or prolonged.
Planned or unexpected.
Accompanied by good substitute care.
Accompanied by poor substitute care.
Separation does not necessarily cause developmental harm.
Deprivation
Deprivation is the loss or disruption of an attachment that has already formed.
For deprivation to occur:
A relationship must have existed.
The relationship is then interrupted or lost.
Suitable substitute emotional care is unavailable or inadequate.
Privation
Privation is the failure to form an attachment in the first place.
A child experiencing privation may never have had:
One consistent caregiver.
A stable source of comfort.
An opportunity to develop trust.
A primary attachment figure.
This could occur when care is provided by many changing adults with limited emotional interaction.
The key distinction
Concept | Has an attachment already formed? | What happens? |
Separation | Possibly | Child is physically apart from caregiver |
Deprivation | Yes | Existing attachment is disrupted and emotional care is lost |
Privation | No | Child never forms a stable attachment |
Institutionalisation | Varies | Child lives in institutional care, which may involve privation, deprivation or neither |
Example of deprivation
A child forms a strong attachment to a parent during infancy.
The parent then disappears from the child’s life, and no consistent substitute caregiver is available.
This is deprivation because an existing attachment has been disrupted.
Example of privation
A child spends the first years of life with many changing carers and never has the opportunity to form a stable attachment.
This is privation because there was no established attachment to lose.
Why the distinction matters
Deprivation and privation may have different causes and consequences.
If a study examines children who never formed attachments, it cannot provide clear evidence about the effects of losing an attachment.
Rutter argued that Bowlby sometimes failed to distinguish between these experiences.
This weakens conclusions that all developmental difficulties were caused by maternal deprivation.
Maternal deprivation and institutionalisation
Institutionalisation refers to living in an institutional setting such as an orphanage or residential care facility.
Institutional care may involve:
Many children.
Limited caregiver attention.
High staff turnover.
Restricted stimulation.
Few opportunities for close relationships.
However, institutionalisation is not identical to deprivation.
An institution could provide:
Stable key workers.
Warm emotional care.
Consistent routines.
Opportunities to form attachments.
Alternatively, poor institutional conditions may produce:
Privation.
Deprivation.
Intellectual understimulation.
Nutritional difficulties.
Several forms of developmental adversity.
The effects of institutional care and the English and Romanian Adoptees project are examined in the consequences of institutional care.
Bowlby’s 44 juvenile thieves study
Aim
Bowlby investigated whether prolonged early separation was associated with emotional difficulties and delinquency.
He focused particularly on affectionless psychopathy.
Participants
Bowlby examined:
44 young people referred to a child guidance clinic because of stealing.
A comparison group of emotionally disturbed young people who had not been referred for stealing.
The participants and their families were interviewed about:
Early separations.
Family relationships.
Emotional development.
Behaviour.
Findings
Among the 44 thieves:
14 were identified as affectionless psychopaths.
12 of these 14 had experienced prolonged separation from a mother figure during early childhood.
Early prolonged separation was less common among thieves who were not identified as affectionless psychopaths and among the comparison group.
Conclusion
Bowlby concluded that early maternal deprivation was associated with:
Affectionless psychopathy.
Delinquency.
Difficulty forming emotional relationships.
The study supported his claim that prolonged early disruption could have lasting emotional consequences.
Why the finding appears supportive
The particularly high rate of early separation among the affectionless group fits Bowlby’s prediction.
The proposed sequence is:
Early prolonged separation → disrupted emotional development → affectionless psychopathy → increased risk of delinquency
However, the research cannot establish this causal sequence with certainty.
Evaluating the 44 thieves study
Supporting evidence
The association between prolonged separation and affectionless psychopathy supports maternal deprivation.
Most of the affectionless thieves had experienced significant early separation.
This suggests that the relationship was not accidental.
Retrospective data
Information about early childhood was collected after the developmental difficulties had appeared.
Parents and young people had to remember experiences from earlier years.
These accounts may have been affected by:
Forgetting.
Reconstruction.
Current family difficulties.
A desire to explain the stealing.
Interviewer expectations.
This reduces the reliability of the separation histories.
Researcher bias
Bowlby conducted interviews and made judgements about affectionless psychopathy.
He already believed maternal deprivation caused later difficulties.
His expectations may therefore have influenced:
The questions he asked.
The details he emphasised.
The interpretation of behaviour.
The assignment of diagnostic labels.
Using independent assessors unaware of the children’s histories would have reduced this risk.
Correlation does not establish causation
The study found an association between:
Early separation.
Affectionless psychopathy.
Delinquency.
It did not prove that separation caused these outcomes.
Children who experienced separation may also have experienced:
Family conflict.
Parental mental illness.
Poverty.
Neglect.
Abuse.
Disrupted education.
Genetic vulnerabilities.
These factors could contribute to both separation and later difficulties.
Clinical and unrepresentative sample
The participants were children referred to a clinic.
They may not represent:
All separated children.
Children who experienced separation without later problems.
The wider population.
Children from different cultures and circumstances.
The findings may therefore have limited generalisability.
Pre-existing differences
Some children may have displayed emotional or behavioural difficulties before the separation.
These difficulties could have:
Increased family stress.
Contributed to placement changes.
Made separation more likely.
Continued after the separation.
The direction of cause and effect may therefore be unclear.
Goldfarb’s research
Goldfarb compared children raised in institutions with children placed in foster homes.
The children who remained in institutions showed poorer intellectual and social outcomes than those placed in foster care.
Support for Bowlby
The results suggest that a lack of stable early relationships may be associated with:
Lower intellectual performance.
Poorer social development.
Emotional difficulties.
This is consistent with Bowlby’s proposed consequences of deprivation.
A problem with interpretation
The children differed in more than access to one mother figure.
Institutional care may also have involved:
Less stimulation.
Fewer educational opportunities.
Poorer physical care.
Less individual attention.
More changing caregivers.
The results cannot show that maternal deprivation alone caused the difficulties.
Some institutional children may also have experienced privation rather than deprivation.
Rutter’s criticism
Confusing deprivation and privation
Michael Rutter argued that Bowlby did not distinguish clearly enough between:
Losing an attachment.
Never forming an attachment.
Children raised from infancy without a stable caregiver may experience privation.
Their developmental difficulties cannot automatically be explained by maternal deprivation because no attachment existed to be deprived.
Why this weakens the theory
If evidence used to support maternal deprivation comes from privated children, it does not test the theory accurately.
The causes may be:
Failure to form any attachment.
Poor institutional care.
Lack of stimulation.
Malnutrition.
Several interacting disadvantages.
The term maternal deprivation may therefore combine experiences that should be studied separately.
Rutter’s broader approach
Rutter emphasised that outcomes depend on:
The reason for separation.
The quality of substitute care.
Family conflict before separation.
The child’s later experiences.
Whether the child had formed an attachment.
Whether separation is one part of wider adversity.
This provides a more detailed explanation than treating all separations as equivalent.
Evidence of recovery
Koluchová’s Czech twins
Koluchová reported the case of identical twin boys who experienced severe early mistreatment and social isolation.
After removal from the harmful environment, they received stable and affectionate care.
The twins later showed substantial improvement in:
Language.
Intellectual development.
Social relationships.
Emotional functioning.
Why the twins challenge Bowlby
Their recovery suggests that early developmental damage may not always be permanent.
Stable later care may allow:
New attachments.
Cognitive development.
Improved social skills.
Revision of expectations about relationships.
This supports a sensitive-period interpretation rather than a completely irreversible critical period.
Limitation of the evidence
The research concerned an unusual case.
The twins may have benefited from:
Their relationship with each other.
Genetic similarities.
Particularly supportive later care.
Individual resilience.
A case study cannot establish that every child will recover in the same way.
Romanian orphan research
Research involving children adopted from Romanian institutions also suggests that earlier placement in supportive families is associated with better outcomes.
This provides evidence that:
Early adversity matters.
Duration matters.
High-quality later care can support recovery.
Outcomes are not completely fixed.
However, institutional deprivation includes several disadvantages and cannot isolate maternal deprivation alone.
Alternative explanations for developmental difficulties
Institutional understimulation
Poor intellectual development may result from limited:
Language input.
Play.
Education.
Exploration.
Individual attention.
These factors may explain reduced IQ more directly than separation from a mother figure.
Family adversity
Children experiencing deprivation may also experience:
Poverty.
Conflict.
Abuse.
Parental illness.
Unstable housing.
School disruption.
Later difficulties may reflect accumulated adversity rather than one disrupted attachment.
Genetic influences
Parents and children share genes.
A parent’s psychological or behavioural difficulties may:
Increase the likelihood of family disruption.
Be partly inherited by the child.
Contribute to later emotional or behavioural problems.
An apparent environmental effect may therefore contain a genetic influence.
Temperament
Children differ in temperament.
A more reactive or difficult temperament could:
Affect the caregiver-child relationship.
Increase family stress.
Influence reactions to separation.
Contribute to later behaviour.
This does not mean the child causes deprivation, but it shows that development involves interaction between several factors.
Continuing care quality
Developmental outcomes may depend more on continuing care than the original separation.
A child who receives stable and sensitive later care may improve.
A child whose adversity continues may experience greater difficulties.
The later environment can therefore strengthen or reduce the effect of early experiences.
Is maternal deprivation deterministic?
Determinism is the view that behaviour is caused by factors outside the person’s control.
A strict interpretation of Bowlby’s theory may imply:
Early deprivation inevitably produces permanent developmental damage.
This is too strong.
Research indicates substantial individual variation.
Some children show serious difficulties, while others demonstrate:
Recovery.
Resilience.
Successful later relationships.
Typical intellectual development.
A more appropriate interpretation is probabilistic:
Maternal deprivation may increase the risk of developmental difficulties, particularly when it is prolonged and combined with poor substitute care.
Social sensitivity and gender bias
Potential blame placed on mothers
The term maternal deprivation may suggest that mothers are personally responsible for any later difficulties experienced by their children.
This could produce:
Guilt among working mothers.
Negative attitudes towards childcare.
Pressure on women to remain at home.
Blame after unavoidable separation.
Undervaluing of fathers and other caregivers.
Bowlby’s actual concept
Bowlby referred to a mother or permanent mother substitute.
The theory does not require the caregiver to be:
Female.
Biologically related.
The only person providing care.
The central requirement is a stable, continuous and emotionally responsive relationship.
Modern interpretation
A less gender-biased interpretation focuses on:
Quality of care.
Stability.
Emotional availability.
Continuity of attachment.
Suitable substitute caregivers.
This avoids assuming that only biological mothers can provide healthy attachment.
Practical applications
Hospital visiting
Bowlby’s work influenced changes in hospital care.
Young children were once frequently separated from parents during hospital stays.
Modern practice is more likely to encourage:
Parental visits.
Parents staying with children.
Familiar objects and routines.
Continuity of emotional support.
Preparation for unavoidable separation.
Institutional care
The theory encouraged institutions to provide:
Consistent key workers.
Smaller caregiver-child ratios.
Opportunities for attachment.
Stable placements.
Emotionally responsive care.
Foster care and adoption
The theory supports:
Early placement where appropriate.
Avoiding repeated placement changes.
Maintaining continuity with familiar caregivers.
Supporting adoptive and foster relationships.
Preparing children carefully for transitions.
Parental leave and childcare
Bowlby’s work has influenced discussions about:
Parental leave.
Flexible working.
Affordable high-quality childcare.
Continuity of care.
However, the evidence should not be used to claim that working parents necessarily cause deprivation.
Consistent and responsive childcare can provide suitable emotional care.
Practical usefulness does not prove the theory
A theory can produce valuable policies even when some of its original claims are overstated.
The practical lesson that children benefit from stable emotional care is well supported.
This does not prove that:
One biological mother is always necessary.
Every separation is damaging.
Later recovery is impossible.
Maternal deprivation alone causes delinquency.
A balanced evaluation
What the theory explains well
Bowlby’s theory highlights:
The importance of early emotional care.
The risks of prolonged relationship disruption.
The value of continuity.
Possible links between attachment and later development.
The need for suitable substitute care.
It also generated research and practical reform.
What the theory explains less well
The theory may:
Confuse deprivation with privation.
Underestimate recovery.
Overemphasise one attachment figure.
Overlook wider environmental adversity.
Encourage deterministic interpretations.
Place unfair responsibility on mothers.
Rely on correlational and retrospective evidence.
Overall judgement
Maternal deprivation is best viewed as one risk factor within a wider developmental system.
Prolonged loss of a stable attachment during early childhood may contribute to intellectual, emotional and social difficulties, especially when substitute care is poor.
However, developmental outcomes are also influenced by:
Whether an attachment had formed.
Length and timing of separation.
Quality of later care.
Wider adversity.
Individual resilience.
Educational and social opportunities.
Applying maternal deprivation to scenarios
Scenario 1: good substitute care
Elijah’s mother is away for two months. Elijah stays with his father, with whom he already has a close relationship.
A strong application would state:
Elijah is separated from his mother, but this does not necessarily amount to maternal deprivation. His father provides a stable attachment relationship and suitable emotional care, reducing the likelihood that the separation will produce the consequences predicted by Bowlby.
Scenario 2: repeated placement changes
A young child moves through six foster homes over two years.
A strong application would state:
Repeated changes of caregiver may produce accumulated separation and prevent continuity of emotional care. Bowlby would predict an increased risk of an insecure internal working model, relationship difficulties or emotional problems.
Scenario 3: no original attachment
A child has been cared for by many changing staff since birth and has never formed a stable attachment.
A strong application would state:
This is more accurately described as privation rather than deprivation because the child did not form an attachment that was later lost. Using the case as evidence for maternal deprivation would confuse two different experiences.
Scenario 4: later recovery
A deprived child is adopted into a stable and responsive family and gradually develops close relationships.
A strong application would state:
The child’s improvement challenges a strict interpretation that early deprivation causes permanent damage. It suggests that later high-quality care can support recovery and that the early period may be sensitive rather than completely fixed.
Scenario 5: developmental difficulties
A child who experienced prolonged early separation later shows poor school performance and little guilt after hurting others.
Bowlby might explain:
Poor school performance through impaired intellectual development.
Lack of guilt through affectionless psychopathy.
Both outcomes as possible consequences of deprivation during the critical period.
A balanced answer should add that other variables may also explain the behaviour.
Answering examination questions
Outline questions
For an outline of maternal deprivation, include:
Prolonged disruption of an attachment.
Absence of suitable substitute emotional care.
The critical period.
Intellectual or emotional consequences.
Affectionless psychopathy where relevant.
Distinction questions
Use direct comparative wording.
For example:
Deprivation involves losing an attachment that has already formed, whereas privation involves failing to form an attachment in the first place.
Do not write two separate definitions without making the difference explicit.
Application questions
Use this structure:
Identify the disruption.
State whether an attachment had already formed.
Consider substitute care.
Link the circumstances to a predicted consequence.
Avoid assuming that the outcome is certain.
Discussion questions
A strong discussion could include:
Bowlby’s 44 thieves.
Supporting institutional evidence.
Retrospective and correlational limitations.
Rutter’s deprivation-privation distinction.
Recovery evidence.
Alternative environmental explanations.
Social sensitivity.
Practical applications.
Evaluation paragraph structure
State the point.
Present supporting evidence.
Explain its implication.
Link it directly to maternal deprivation.
Reach a qualified judgement.
Weak evaluation
Bowlby’s study was biased.
Stronger evaluation
Bowlby both interviewed the participants and classified affectionless psychopathy, despite already expecting deprivation to cause delinquency. His expectations may have influenced the questions and diagnoses, reducing the validity of the evidence used to support maternal deprivation.
Hints from the Examiner Reports 💡
Examiner hint: Define deprivation accurately. It involves prolonged or accumulated separation from a mother figure and inadequate substitute emotional care, not every physical separation.
Examiner hint: Include the critical period and specific possible consequences such as reduced intellectual development, emotional difficulties, delinquency and affectionless psychopathy.
Examiner hint: Apply the theory to the exact evidence in a scenario. For example, link below-average educational performance to intellectual effects or lack of empathy to affectionless psychopathy.
Examiner hint: Distinguish deprivation from privation. A child who never formed an attachment has experienced privation rather than the loss of an existing attachment.
Examiner hint: Research evidence must be linked back to the theory. Describing the 44 thieves study without explaining whether it supports maternal deprivation is incomplete.
Examiner hint: Methodological evaluation gains value only when its implications for the maternal deprivation explanation are explained.
Examiner hint: Useful discussion includes supporting and contradictory evidence, reversibility, institutional research, the deprivation-privation distinction and practical applications.
The June 2023 AQA mark scheme credited the absence of a mother figure, the critical period, prolonged or accumulated separation, reduced intelligence, emotional problems, delinquency and affectionless psychopathy. It also identified Rutter’s deprivation-privation distinction and evidence of recovery as relevant evaluation.
AQA’s examiner report noted that stronger responses applied specific consequences to the scenario and used evidence such as the 44 juvenile thieves, Romanian orphan research and the Czech twins. It also warned against including excessive research detail without maintaining focus on the question.

[1 mark]
reveal mark scheme and indicative content
Answer: C. The failure to form an attachment in the first place
Question 2
Define maternal deprivation.
[2 marks]
reveal mark scheme and indicative content
Mark scheme
AO1 = 2
2 marks: Clear definition referring to prolonged or repeated disruption of the child's relationship with the mother or mother figure, particularly during the critical period.
1 mark: Limited or partial definition.
Indicative content
Prolonged or accumulated separation from the mother figure.
According to Bowlby, this may harm psychological development if adequate substitute emotional care is unavailable.
Example answer
Maternal deprivation is prolonged or repeated separation from the mother or mother figure during early childhood, where the child's emotional care and attachment relationship are disrupted.
AQA defines deprivation within Bowlby's theory in terms of prolonged or accumulated separation from the mother figure.
Question 3
Explain one difference between separation and deprivation.
[3 marks]
reveal mark scheme and indicative content
Mark scheme
AO1 = 3
1 mark: Separation refers to the child being physically apart from an attachment figure.
1 mark: Deprivation involves the loss or disruption of emotional care associated with that attachment.
1 mark: Clear distinction showing that separation does not necessarily result in deprivation.
Indicative content
A child can be separated from their primary attachment figure without being deprived if a familiar substitute caregiver provides appropriate emotional care.
Example answer
Separation simply means being physically apart from an attachment figure, whereas deprivation involves the disruption or loss of the emotional care provided by that attachment. Therefore, separation does not necessarily cause deprivation if suitable substitute care is available.
Question 4
Explain one difference between deprivation and privation.
[3 marks]
reveal mark scheme and indicative content
Mark scheme
AO1 = 3
1 mark: Deprivation involves disruption or loss of an attachment that has formed.
1 mark: Privation involves failure to form an attachment in the first place.
1 mark: Clear comparison or elaboration.
Example answer
Deprivation occurs when an existing attachment is disrupted or lost, whereas privation occurs when a child has never formed an attachment in the first place.
This distinction is particularly important when evaluating Bowlby's evidence, because AQA explicitly credits Rutter's criticism that Bowlby did not adequately distinguish deprivation from privation
Question 5
A two-year-old child spends six weeks away from her mother but stays with a familiar grandparent who provides warm and consistent care.
Use your knowledge of maternal deprivation to explain why the child may not experience serious developmental difficulties.

AO2 = 4
Award 1 mark each for:
The child is separated from her mother for six weeks.
Separation alone does not necessarily mean serious maternal deprivation.
The familiar grandparent provides warm and consistent substitute emotional care.
This may maintain an attachment relationship and reduce the risk of the developmental consequences Bowlby associated with deprivation.
Indicative content
Bowlby's theory concerns disruption of the child's emotional bond, not simply physical absence from the biological mother.
Example answer
Although the child is physically separated from her mother, she is cared for by a familiar grandparent who provides warm and consistent emotional care. This means the separation may not result in serious deprivation because she still has an appropriate substitute attachment figure. Therefore, the harmful developmental effects predicted by Bowlby are less likely.
Question 6
A child formed an attachment to his father during infancy. His father then left, and the child experienced several changes of foster placement.
Explain how Bowlby’s maternal deprivation theory could account for later relationship difficulties.
[6 marks]

Mark scheme
AO2 = 6
Award credit for clear application of maternal deprivation theory.
Indicative content
The child had formed an attachment to his father, so the father's departure represents disruption of an existing attachment.
Repeated changes of foster placement could produce prolonged or accumulated deprivation.
Bowlby argued that deprivation during the critical period could have long-term emotional effects.
It could disrupt the child's internal working model of relationships.
The child may develop expectations that caregivers are unreliable or relationships are unstable.
These expectations could contribute to later difficulties trusting others or maintaining relationships.
AQA's examiner report specifically credits accumulated separation, an impaired internal working model and later relationship difficulties when applying maternal deprivation theory.
Example answer
The child had already formed an attachment to his father, so his father's departure could produce deprivation. The repeated foster placements could then create accumulated disruption to attachment during the critical period. Bowlby argued that such deprivation may damage emotional development and the internal working model. The child may learn that close relationships are unstable or that caregivers cannot be relied upon, which could make trusting and maintaining relationships more difficult later.
Question 7
Outline Bowlby’s 44 juvenile thieves study and explain how its findings support maternal deprivation.
[6 marks]

Mark scheme
AO1/AO3 = 6
Award credit for both study detail and the link to maternal deprivation.
Indicative content
Bowlby studied 44 children who had been referred for stealing.
Their emotional characteristics and early family/separation histories were investigated.
A comparison group of children who had not been referred for theft was also considered.
Some of the thieves were classified as affectionless psychopaths, showing little affection, guilt or concern for others.
Affectionless psychopathy was strongly associated with prolonged early separation from the mother or mother figure.
Bowlby concluded that early maternal deprivation could contribute to later emotional problems and delinquency.
AQA recognises Bowlby's 44 juvenile thieves as relevant evidence supporting maternal deprivation and identifies affectionless psychopathy and delinquency as predicted consequences of deprivation.
Example answer
Bowlby studied 44 children who had been referred to a child guidance clinic because of stealing. He examined their early family experiences and identified some as affectionless psychopaths, meaning they showed little guilt or affection towards others. These children were particularly likely to have experienced prolonged separation from their mother or mother figure early in life. Bowlby argued that this association supported his theory that maternal deprivation during the critical period can contribute to later emotional difficulties and delinquent behaviour.
Question 8
A researcher finds the following results:
Early experience | Mean relationship-difficulty score |
No prolonged separation | 7.2 |
Prolonged separation with stable substitute care | 8.1 |
Prolonged separation with changing caregivers | 16.7 |
Describe the pattern shown in the results. Explain what the findings suggest about maternal deprivation.

Award up to 3 marks for describing the pattern and 3 marks for explaining its significance.
Indicative content
Pattern
Relationship difficulties are lowest with no prolonged separation, 7.2.
Separation with stable substitute care produces only a small increase, to 8.1.
Separation combined with changing caregivers produces a much higher score, 16.7.
The difference between the two separation conditions is 8.6 points.
Conclusion
Prolonged physical separation alone may not be sufficient to produce serious developmental difficulties.
Stable substitute emotional care appears to reduce the effects of separation.
Repeated changes of caregiver and disruption to attachment relationships may be more damaging.
This suggests Bowlby's emphasis should be on deprivation or disrupted emotional care rather than separation alone.
Example answer
Children with no prolonged separation have a mean relationship-difficulty score of 7.2, while those separated but given stable substitute care score only slightly higher at 8.1. In contrast, children who experience separation with changing caregivers score 16.7. This suggests that separation itself may not be the main cause of later problems. Stable substitute care may protect children, whereas repeated disruption of attachment relationships appears to be associated with much greater difficulties.
Question 9
Explain one methodological limitation of research used to support Bowlby’s maternal deprivation theory.
[4 marks]
reveal mark scheme and indicative content
Mark scheme
AO3 = 4
Award credit for one clearly developed methodological limitation.
Indicative content
For example, Bowlby's 44 thieves study:
The research was correlational.
Early separation and later delinquency or affectionless psychopathy were associated, but separation was not experimentally manipulated.
Other variables, such as family conflict, poverty or poor-quality care, could have contributed to both separation and later difficulties.
Therefore, the evidence cannot establish that maternal deprivation caused the later problems.
Also credit:
retrospective reports of childhood separation may be inaccurate
Bowlby's involvement in interviewing and classifying participants could create researcher bias
difficulties separating the effects of deprivation from privation.
AQA specifically accepts methodological evaluation when it is clearly linked back to the validity of evidence for maternal deprivation, and also recognises Bowlby's failure to distinguish deprivation from privation as an important criticism.
Example answer
One limitation is that Bowlby's evidence was correlational. The 44 thieves study found an association between early separation and later affectionless psychopathy, but this does not establish cause and effect. Other factors, such as difficult family circumstances or poor-quality care, could have caused both the separation and later behavioural problems. Therefore, the study cannot demonstrate that maternal deprivation itself caused the later difficulties.

Discuss Bowlby’s theory of maternal deprivation as an explanation of developmental difficulties.
