Social relationships

Social relationships in development

Humans are inherently social beings and learning how to form and maintain relationships is central to development. These relationships include parents, siblings, peers and romantic partners. They play a crucial role in cognitive development, social development, health and overall wellbeing.

The family as a social system

The family provides the earliest and often most enduring social experiences. It includes multiple interconnected relationships such as partner relationships, parent–child interactions and sibling bonds. These relationships shape emotional security, behaviour and identity over time.

Ecological systems and family functioning

Bronfenbrenner’s ecological systems perspective highlights how families operate within broader systems. Families aim for homeostasis, maintaining stability through routines, rituals and traditions that support a shared identity. At the same time, adaptability is essential to respond to change. Boundaries regulate how open or closed a family is to outside influences, and effective functioning requires a balance between stability and flexibility.

Parental behaviour and socialisation

Parents influence children through reinforcement, modelling and environmental control. Reinforcement involves rewarding or disciplining behaviour to shape norms. Modelling occurs when children learn by observing others, often unintentionally adopting both positive and negative behaviours. Parents also manage the child’s environment, including physical, social and digital contexts.

Parenting styles and developmental outcomes

Parenting styles differ in levels of responsiveness and control. Uninvolved parenting is associated with neglect, insecure attachment, poor self-esteem and antisocial behaviour. Permissive parenting often leads to impulsivity, low self-control and lack of direction. Authoritarian parenting is linked to withdrawal, anxiety, low confidence and difficulties in peer relationships. Authoritative parenting is generally associated with the most positive outcomes, including strong social skills, self-esteem, adaptability and lower antisocial behaviour.

Criticisms of parenting style research

Much research has focused primarily on mothers, often neglecting fathers’ roles and whether parenting styles are shared. It may not account for differences between single- and two-parent households, child temperament or socioeconomic context. Cultural and ethnic differences are also often overlooked, limiting generalisability.

Parental relationships and wider family context

Relationships between parents influence the emotional climate of the household and children’s development. Family functioning must also be understood within broader contexts such as poverty, which can place stress on relationships and limit resources.

Sibling relationships

Siblings provide one of the most frequent sources of interaction outside parents. They offer opportunities for learning, support and conflict. Birth order can shape experiences, with differences between eldest and later-born children. Sibling relationships often evolve from rivalry and ambivalence in early years to trust and emotional support later on.

Divorce and remarriage

Changes in family structure, such as divorce and remarriage, can significantly affect children’s emotional and social development, depending on factors such as conflict, stability and support systems.

Age of parenthood

Early parenthood, particularly in teenage years, is associated with increased risks including economic hardship, delayed cognitive development in children and behavioural issues such as aggression and poor impulse control. Parenthood in the twenties and thirties is often linked to greater satisfaction, knowledge and sensitivity in parenting. Later parenthood, often defined as over 30, may involve more stable life circumstances and increased parental investment, leading to more positive parent–child relationships, though it can also be associated with fertility challenges.

Peer relationships in infancy and early years

In the first six months, infants show curiosity and responsiveness to peers, though interactions are mostly reactive. Between six months and one year, interactions become more active. Toddlers increasingly prefer peer interaction and engage in more social play.

Peer relationships in childhood and adolescence

In early childhood, play becomes more structured and social. As children grow, peers become increasingly influential, particularly during adolescence. Peers shape interpersonal behaviour, friendships, fashion choices and leisure activities. Parents continue to influence academic choices, career aspirations and structured activities, though their influence decreases somewhat with age.

Peer acceptance and sociometric status

Peer acceptance is essential for healthy social development and represents a child’s first experience of social evaluation outside the family. It is often measured using sociometric techniques, where children nominate peers they like or dislike, revealing social status within the group.

Victimisation and bullying

Victimisation involves repeated bullying, which may be physical, relational or online. It is associated with increased anxiety, depression, loneliness and social withdrawal. Victims often experience rejection, low self-esteem and difficulties adjusting to school. Strong friendships can act as a protective buffer against these effects.

Peer rejection

In the short term, peer rejection leads to loneliness, dissatisfaction and difficulty forming friendships. Long-term consequences can include poor academic achievement, school avoidance, increased risk of harassment, depression and antisocial behaviour. It may also delay key life transitions such as career development and forming long-term relationships.

Development of friendship

Friendships evolve over time, becoming more complex and meaningful. Early friendships are based on shared activities, while later friendships involve trust, intimacy and mutual understanding.

Romantic relationships

Romantic relationships bring both costs and rewards. Costs include increased conflict, mood swings and risk of depression following breakups. Rewards include enhanced self-worth, a sense of belonging and emotional support. As individuals develop, relationships tend to become longer and more meaningful, shifting from superficial factors such as appearance and status to deeper qualities like compatibility, shared values and emotional intimacy.
