Theories explaining the development of attachment in children

Attachment refers to the emotional bond that forms between a child and their caregiver, playing a crucial role in social and emotional development. Various theories have been proposed to explain how these bonds develop over time.

Key theories of attachment development

• Behaviorist theory - This theory suggests that attachment forms through conditioning. A caregiver becomes associated with meeting the child's basic needs, like food, leading to a learned emotional bond. The child associates the caregiver with comfort and security through repeated positive experiences.
• Humanistic theory - Focused on the child's innate need for love and acceptance, this theory posits that attachment develops when caregivers provide unconditional positive regard, fostering a sense of security and self-worth in the child.
• Bowlby's theory - John Bowlby proposed that attachment is an evolutionary mechanism essential for survival. Infants are biologically predisposed to form bonds with caregivers who protect them. He introduced the idea of a 'critical period', a specific window in early life during which attachment must form for healthy emotional development. If missed, forming secure bonds later becomes challenging.

Bowlby's four stages of attachment

Bowlby outlined four progressive stages through which attachment develops between an infant and their caregiver:

1. Pre-attachment (birth to 6 weeks) - Infants show no specific preference for any caregiver. They respond to any comforting presence with innate behaviours like crying or smiling to attract attention.
2. Attachment in the making (6 weeks to 6-8 months) - Infants begin to distinguish between familiar and unfamiliar people, showing a preference for primary caregivers through more directed responses, such as smiling more at known faces.
3. Clear-cut attachment (6-8 months to 18-24 months) - A strong bond forms with a specific caregiver, often the mother. Infants display separation anxiety when apart from this figure and seek them for comfort during distress.
4. Formation of reciprocal attachment (18-24 months onwards) - As language and cognitive skills develop, children understand caregivers' behaviours better and form mutual relationships. Separation anxiety decreases as they gain independence while maintaining the bond.

Ainsworth's classification of parent-infant attachment types

Mary Ainsworth expanded on Bowlby's work by identifying distinct patterns of attachment between infants and their caregivers, based on how children respond to stress and reunion with their caregiver.

Types of attachment identified by Ainsworth

• Secure attachment - Children feel confident in their caregiver's availability and responsiveness. They explore their environment freely when the caregiver is present, show distress when separated, and are easily comforted upon reunion.
• Insecure avoidant attachment - Children appear independent and avoid seeking comfort from their caregiver, even when distressed. They may ignore the caregiver upon reunion, often due to consistent rejection or unresponsiveness in early interactions.
• Insecure resistant attachment - Children show anxiety and uncertainty, often clinging to the caregiver but resisting comfort upon reunion. This type arises from inconsistent caregiving, where the child is unsure of the caregiver's reliability.
• Insecure disorganised attachment - Children display confused or contradictory behaviours, such as approaching the caregiver while looking away or freezing. This often results from frightening or unpredictable caregiver behaviour, leading to a lack of coherent attachment strategy.

Schaffer and Emerson's stages of attachment development

Schaffer and Emerson conducted research in the 1960s to understand how attachment evolves over the first year of life, identifying distinct stages based on infants' social behaviours.

Stages of attachment progression

1. Indiscriminate attachments (0-2 months) - Infants respond similarly to all caregivers, showing no preference. They seek comfort from anyone nearby through cries and smiles, focusing on basic needs being met.
2. Specific attachments (2-7 months) - A preference for a primary caregiver emerges, often the person who spends the most time with them. Infants begin to show distress when separated from this figure.
3. Single attachment figure (7-9 months) - A strong bond forms with one main caregiver, typically the mother. Infants exhibit clear separation anxiety and stranger anxiety, becoming wary of unfamiliar people.
4. Multiple attachments (9 months onwards) - Children start forming additional bonds with other familiar figures, such as fathers, grandparents, or siblings. While the primary attachment remains strongest, these secondary bonds become significant for emotional support.

The Strange Situation as an assessment method for attachment

The Strange Situation is a controlled observation method developed by Mary Ainsworth to assess individual differences in attachment styles among infants, focusing on their reactions to separation and reunion with their caregiver.

Methodology of the Strange Situation

• Setting - Conducted in a laboratory with a two-way mirror for unobtrusive observation, the environment includes toys to encourage exploration.
• Participants - Typically involves infants aged 12-18 months and their primary caregiver.
• Procedure - A series of eight episodes, each lasting about three minutes, designed to mildly stress the infant:
  • Caregiver and infant enter the room together.
  • A stranger enters, interacts with the caregiver, then plays with the infant.
  • Caregiver leaves, leaving the infant with the stranger.
  • Caregiver returns, and the stranger leaves.
  • Caregiver leaves again, leaving the infant alone.
  • Stranger returns to comfort the infant.
  • Caregiver returns for a final reunion.
• Key observations - Researchers assess the infant's behaviour during separation (distress levels), interaction with the stranger (stranger anxiety), and response to reunion (seeking comfort or avoidance).
• Classification - Based on these behaviours, infants are categorised into secure, insecure avoidant, insecure resistant, or insecure disorganised attachment types.

Strengths and limitations of the Strange Situation

• Strengths - Provides a standardised way to observe attachment behaviours under controlled conditions, allowing for reliable comparisons across individuals.
• Limitations - Conducted in an artificial setting, which may not reflect real-life interactions. Cultural differences in caregiving practices can also influence results, as behaviours considered secure in one culture may differ in another.

Consequences of attachment failure and related concepts

When attachment does not form properly due to separation or lack of consistent care, it can have significant short-term and long-term effects on a child's emotional and social development. Several key concepts and studies highlight these consequences.

Bowlby's key concepts on attachment failure

• Internal working model - Bowlby suggested that early attachment experiences create a mental framework for future relationships. A secure attachment leads to positive expectations of others, while insecure or failed attachments can result in distrust or fear of closeness in later life.
• Maternal deprivation hypothesis - Bowlby argued that prolonged separation from the primary caregiver, especially during the critical period, causes emotional and intellectual damage. This deprivation disrupts the child's ability to form healthy bonds.
• Short-term effects of maternal deprivation - Immediate consequences include distress, anxiety, and withdrawal when separated from the caregiver, often seen in hospitalised children or those in temporary care.
• Long-term effects of maternal deprivation - Later in life, individuals may struggle with forming trusting relationships, experience emotional instability, or exhibit delinquent behaviour due to early deprivation.

Bowlby's '44 juvenile thieves' research

• Method - Bowlby studied 44 juvenile delinquents who had been referred to a child guidance clinic, comparing them to a control group of non-delinquents. He assessed their early life experiences through interviews.
• Results - A significant number of the delinquents had experienced prolonged separation from their primary caregiver during early childhood, compared to the control group. Many showed 'affectionless psychopathy', a lack of empathy or guilt.
• Conclusions - Early maternal deprivation can contribute to antisocial behaviour and emotional difficulties, supporting the idea that secure attachment is vital for healthy development.
• Evaluation - The study relied on retrospective data, which may be biased or inaccurate. It also focused on extreme cases, limiting generalisation to the wider population.

Rutter's perspective on privation

• Distinction between deprivation and privation - Michael Rutter clarified that deprivation refers to the loss or disruption of an existing attachment (e.g., through separation), while privation describes the failure to form any attachment in the first place due to neglect or institutional care.
• Consequences of privation - Rutter argued that privation has more severe effects than deprivation, often leading to profound developmental delays, difficulty forming relationships, and conditions like reactive attachment disorder. Recovery is possible but requires early intervention and a nurturing environment.

Robertson's stages of separation behaviour

James and Joyce Robertson studied the effects of separation on young children, particularly in contexts like hospitalisation, identifying a predictable pattern of emotional responses when separated from their primary caregiver.

Stages of emotional response to separation

1. Protesting - Immediately after separation, children show intense distress, crying, screaming, and searching for their caregiver. This stage reflects a desperate attempt to reunite.
2. Desperation - As separation continues, children become quieter but remain deeply upset, showing signs of hopelessness. They may withdraw and lose interest in their surroundings.
3. Detachment - Over time, children appear to cope by emotionally detaching from the caregiver. They may seem calm and engage with others, but this often masks a lack of trust. Upon reunion, they may reject or ignore the caregiver, indicating lasting emotional impact.

These stages highlight the importance of minimising prolonged separations during early childhood to prevent long-term emotional harm.
