Social & Emotional Development — Bowlby, Ainsworth & Burke
Social and Emotional Development Across the Lifespan
Social and emotional development describes how individuals build relationships, develop a sense of who they are, and learn to manage their feelings. It begins in the first weeks of life with the formation of an attachment bond and continues through adolescent friendships, adult partnerships, and the social challenges of later life. Health and social care practitioners — from nursery key-workers to residential care home staff — need a clear understanding of how this dimension of development changes across the five life stages.
Infancy: Bowlby’s Attachment Theory
The most important social and emotional development in infancy is the formation of attachment — a close emotional bond between an infant and their primary caregiver. John Bowlby (1907–1990) proposed that attachment is a biological drive: infants are programmed to seek proximity to a caregiver in order to survive. His theory had several key claims that practitioners must be able to name and explain.
Bowlby argued for monotropy — the idea that infants form one primary attachment that is qualitatively different from all others. This primary figure (usually, but not always, the mother) provides the infant with an internal working model: a mental template of what relationships are like, which shapes expectations of all future relationships. Bowlby also proposed a critical period of approximately 0–3 years, within which a secure attachment must form or the individual will suffer lasting developmental harm.
Bowlby’s 44 Thieves Study (1944) compared 44 juvenile thieves with a control group. He found that 14 of the thieves displayed “affectionless psychopathy” — a lack of concern for others — and that a significant proportion of these had experienced maternal deprivation (disruption to the primary attachment) in early childhood. Bowlby used this as evidence that broken attachment bonds in the critical period cause lasting emotional and social damage.
Ainsworth’s Strange Situation
Mary Ainsworth (1913–1999) wanted to study how the quality of the attachment bond varied between infants. She designed the Strange Situation (1970) — a controlled laboratory procedure in which an infant is placed in a series of brief scenarios involving a caregiver and a stranger. Ainsworth observed the infant’s behaviour during separation from the caregiver and, crucially, during reunion.
Ainsworth identified three main attachment types from her observations:
Secure attachment (approximately 70% of Ainsworth’s sample): The infant is upset when the caregiver leaves but is easily comforted on return and quickly returns to exploring. This reflects consistent, sensitive caregiving. Securely attached infants develop positive internal working models — they tend to form trusting relationships later in life.
Insecure-avoidant attachment (approximately 15%): The infant shows little distress when the caregiver leaves and appears to ignore them on return. This reflects caregiving that has consistently rejected or ignored the infant’s emotional signals. These infants have learned to suppress attachment-seeking behaviours.
Insecure-resistant (ambivalent) attachment (approximately 15%): The infant is highly distressed when the caregiver leaves and cannot be easily comforted on return — pushing the caregiver away while also seeking closeness. This reflects inconsistent caregiving, where the caregiver sometimes responds sensitively and sometimes does not. The infant is uncertain about whether the caregiver can be relied upon.
A nursery key-worker observing a child who shows little distress at parental drop-off and remains distant at pick-up may note this as a possible indicator of insecure-avoidant attachment — and may raise this with their SENCO or family support worker as part of an early-years welfare assessment.
Bowlby and Ainsworth are distinct contributions: Bowlby explained the existence of attachment and its importance (monotropy, critical period, 44 Thieves); Ainsworth explained how attachment quality varies between infants (secure, insecure-avoidant, insecure-resistant). Both names must be correctly matched to their contribution in exam answers.
Childhood: Self-Concept, Play, and Primary Socialisation
During childhood, children develop a growing sense of self-concept — an awareness of themselves as separate people with distinct characteristics. A young child begins to describe themselves in concrete terms (“I am tall”, “I am good at drawing”) before developing a more complex self-concept in adolescence.
Play is the primary vehicle for social development in childhood. Theorists describe stages of play moving from solitary and parallel play (young toddlers) to associative and cooperative play (older children). Primary school-aged children play in groups, negotiate rules, resolve conflicts, and build friendships based on shared interests — all important social skills practised in an informal setting before formal work relationships develop later.
Primary socialisation — the process of learning values, norms, and expectations from the family — is the dominant social influence in early childhood. As children move through school, secondary socialisation through peers, teachers, and wider society becomes increasingly important. Role models outside the family begin to shape behaviour and self-image.
Adolescence: Identity, Peer Influence, and First Intimate Relationships
Adolescence brings dramatic social and emotional changes. The central emotional task — identity formation — involves working out who you are in relation to your peers, family, culture, and aspirations. Peer groups become more influential than parents in shaping behaviour, values, and lifestyle choices.
Adolescents form their first intimate relationships outside the family. These relationships provide new emotional experiences and are formative for the internal working model of romantic partnerships. Young people also begin to assert autonomy — pushing for independence from parental control — while still depending on their families for security.
Albert Bandura’s social learning theory argues that much of human behaviour is learned through observation and modelling — watching others and imitating their behaviour, particularly when the model is admired or rewarded. Vicarious reinforcement occurs when an individual imitates a behaviour after observing someone else being rewarded for it, without being rewarded themselves. In adolescence, peer role models and social media influencers are particularly powerful models. A teenager who observes peers gaining social approval for a behaviour is more likely to imitate it — whether that behaviour is positive (volunteering, studying) or negative (smoking, risky behaviour). Social care practitioners working with young people in youth clubs or community settings use understanding of social learning to design positive role-model programmes.
Adulthood and Later Adulthood: Relationships, Loss, and Dependency
In adulthood, social networks are typically at their widest. Long-term intimate partnerships, work relationships, friendships, and parenting responsibilities form the fabric of adult social life. Parenthood in particular represents a major shift in social and emotional role — an adult becomes responsible for a new attachment relationship, reversing the direction of caregiving.
In later adulthood, the social and emotional landscape changes again. Retirement can bring a positive sense of freedom but also removes a key source of identity, purpose, and daily social contact. Bereavement of partners and close friends is more frequent, and social networks often shrink. Increased physical dependency can affect self-esteem and the emotional balance of close relationships. Loneliness is a significant and well-documented risk in this life stage — day centres, befriending services, and community groups all aim to address it within the care sector.
