Caregiver-infant Interactions in Humans (AQA A-Level Psychology): Revision Notes

Caregiver-infant Interactions in Humans

What is attachment?

Attachment refers to a lasting, two-way emotional connection between two people, typically a parent and child, that develops gradually over time. This bond becomes evident when infants display stranger anxiety (becoming distressed around unfamiliar people) and separation protest (distress when separated from their primary caregiver).

Key types of caregiver-infant interactions

Communication between carers and infants is sophisticated and occurs in several distinct ways that help build and strengthen attachment bonds:

Interactional synchrony

Interactional synchrony involves infants coordinating their body movements to match the rhythm and pattern of their carer's speech and behaviour. This synchronised interaction, where both parties move in harmony, serves to reinforce the developing attachment bond. It's like a carefully choreographed dance between carer and infant.

Reciprocity

Reciprocity describes the back-and-forth exchange of similar behaviours between carer and infant. For example, when a carer smiles at their baby, the baby smiles back, which then triggers another smile from the carer. This mutual responsiveness helps both parties engage with each other and strengthens their emotional connection.

Bodily contact

Physical touch between carer and infant plays a crucial role in forming attachment bonds, particularly in the immediate period following birth. Skin-to-skin contact, cuddling, and gentle touch help establish the foundation for a secure relationship.

Mimicking

Infants appear to possess an innate ability to copy their carer's facial expressions and gestures. This biological capacity suggests that babies are naturally equipped with mechanisms that facilitate attachment formation from a very early age.

Caregiverese

Adults naturally modify their speech when communicating with infants, using what researchers call caregiverese (also known as 'motherese' or 'baby talk'). This involves speaking in a higher pitch, using song-like intonation, speaking slowly, and being repetitive. This modified communication style helps facilitate interaction between carer and infant and supports attachment development.

Research evidence

Condon & Sander (1974) - Interactional synchrony

Isabella et al. (1989) - Secure attachment and synchrony

Findings: Infants who had developed secure attachments showed greater evidence of interactional synchrony behaviour during their first year of life. Significance: This strengthened the link between synchronised interactions and strong attachment formation.

Klaus & Kennell (1976) - Physical contact study

Method: Compared mothers who had extended physical contact with their babies (several hours daily) with mothers who only had contact during feeding in the first three days after birth. Findings: Mothers with greater physical contact were more likely to cuddle their babies, made more eye contact, and these effects persisted even a year later. Significance: Demonstrated that increased physical contact leads to stronger and closer bond formation.

Meltzoff & Moore (1977) - Infant mimicry

Papousek et al. (1991) - Cross-cultural caregiverese

Findings: The tendency to use rising intonation when interacting with infants was observed across different cultures, including American, Chinese, and German mothers. Significance: This suggests that caregiverese is an innate, biological mechanism that facilitates attachment formation rather than a learned cultural behaviour.

Feldman & Eidelman (2007) - Development of reciprocity

Findings: Reciprocity becomes evident from three months of age, with interactions becoming increasingly frequent. Both infants and carers pay greater attention to each other's verbal and non-verbal signals. Significance: Illustrated the importance of reciprocal interactions in forming attachments and how this develops over time.

Evaluation

Strengths:

• Practical applications: Klaus & Kennell's findings led to changes in hospital practices, with mothers and babies now kept together in the same room after birth rather than being separated, encouraging attachment formation.
• Supporting evidence: De Chateau & Wiberg (1984) replicated Klaus & Kennell's findings with middle-class Swedish mothers, providing cross-cultural support for the importance of early physical contact.
• Research methodology: Frame-by-frame video analysis provides detailed, objective evidence of the subtle interactions between carers and infants.

Limitations:

• Cultural variations: Interactional synchrony is not found in all cultures, which weakens claims that it's essential for attachment formation. Le Vine et al. (1994) found that Kenyan mothers have minimal physical contact or interactions with their infants, yet these infants still develop secure attachments.
• Overgeneralisation of caregiverese: Adults use modified speech patterns with all infants, not just those they have attachments with, suggesting it may aid general communication rather than specifically forming attachments.

Stages of attachment development

Schaffer (1996) identified that infant attachment development follows a predictable pattern that can be divided into several distinct stages. Understanding these stages helps explain how the caregiver-infant interactions described above contribute to the formation of secure attachment bonds over time.
