Caregiver-Infant Interactions in Psychology

Caregiver-Infant Interactions in Humans: Reciprocity and Interactional Synchrony

• Research into caregiver-infant interactions looks at how social interactions between caregivers and infants contribute to the development of attachment.
• Researchers like Brazelton (1975) and Meltzoff and Moore (1977) used controlled observational methods to study reciprocity and interactional synchrony.
• Reciprocity is a two-way interaction where both caregiver and infant respond to and influence each other.
• Meltzoff and Moore found that infants as young as two weeks old mirrored facial expressions.
• Interactional synchrony is where caregiver and infant mirror each other's actions or emotions in a coordinated way.
• Isabella et al. (1989) found greater synchrony correlated with stronger attachments.

###Supporting and Contradictory Studies

• Feldman and Eidelman (2007) found that mothers notice and respond to approximately two-thirds of an infant's alert phases(crucial for reciprocity).
• Condon and Sander (1974) showed interactional synchrony from birth.
• Koepke et al. (1983), failed to replicate Meltzoff and Moore's findings, questioning the validity of those findings..

Evaluation of the Studies

• Strengths:
  • High inter-rater reliability of filmed observations.
  • Ethical methods protect infants.
  • Findings support Bowlby's theories.
• Limitations:
  • Difficulty in interpreting infant behaviour (movements may be random).
  • Cultural bias (interactional synchrony may not be universal).
  • Limited ecological validity (lab settings may not reflect real life interactions).

Application

• Findings inform interventions to improve parent-infant relationships(e.g., parenting programmes for postpartum depression).
• Findings help caregivers in orphanages enhance the likelihood of secure attachments, reducing long-term developmental issues.

Evaluation of Theories

• Interactional synchrony and reciprocity align with Bowlby's evolutionary perspective, suggesting these are biologically pre-programmed for survival.
• Contradictions with learning theory, as the findings emphasize emotional responsiveness over feeding.

Critical Thinking and Wider Issues

• Nature vs Nurture: Interaction between innate predispositions and environmental factors shapes attachment.
• Reductionism: Categorization may be too simplistic and overlook complexity of attachment.
• Ethics and Culture: Collectivist cultures may challenge the universality of the stages.
• Paradigm Influence: Reflects interactionist approach, integrating biological instincts with learned behaviour.

Stages of Attachment Identified by Schaffer, Including Multiple Attachments

• Schaffer and Emerson (1964) investigated the development of attachment and stages of attachment in 60 infants from Glasgow.
• They identified four stages of attachment: asocial, indiscriminate, specific, and multiple attachments.
• Asocial stage (0-6 weeks) : infants show similar responses to people and objects.
• Indiscriminate attachment (6-7 months) : infants prefer people to objects but accept comfort from any adult.
• Specific attachment (7-12 months) : infants form a strong attachment to a person, showing separation and stranger anxiety.
• Multiple attachments (12+ months) : infants develop secondary attachments to other caregivers, family, or friends.

Supporting and Contradictory Studies on Attachment

• Van Ijzendoorn (1993): Found cultural differences in the development of attachment, with collectivist cultures promoting earlier multiple attachments than individualistic cultures.
• Tronick et al. (Efe tribe): supports the idea of a universal sequence of attachment in communal care.
• Bowbly's Monotropic Theory (single attachment figure) is contrasted with Schaffer and Emerson's findings of multiple attachments.
• The study's longitudinal design allowed for the observation of genuine developmental changes but interviews with mothers may introduce social desirability bias.

Evaluation of Schaffer and Emerson's Study

• Strengths:
  • High ecological validity, which enhances the realism of the observed behaviours.
  • Practical applications, as findings informed childcare practices.
• Limitations:
  • Difficulty interpreting infant behaviours in the asocial stage.
  • Cultural bias, as the study was conducted in one specific culture.
  • Limited control over extraneous variables (limitations in interpreting findings).

The Role of The Father

• Historically, fathers were primarily seen as economic providers.
• Modern research highlights their role in emotional, social, and cognitive development.
• Fathers can act as both primary and secondary attachment figures.
• Fathers typically engage in playful and stimulating interactions, fostering exploration and risk-taking.

Supporting and Contradictory Studies on the Role of the Father

• Grossman et al. (2002): found that the quality of a father's play was related to adolescent emotional development and attachments.
• Field (1978): observed fathers as primary caregivers and found that they adopted behaviours similar to mothers.
• MacCallum and Golombok (2004), found that children raised in single-mother or same-sex households did not have significant differences compared to those with fathers.

Evaluation of The Role of the Father

• Strengths:
  • Flexible parenting roles, challenging traditional gender norms.
• Limitations:
  • Inconsistent findings on the father's role, with different studies emphasizing different aspects.
  • Cultural bias, as research is often conducted in Western societies.
  • Reductionism in focusing on specific father roles while overlooking the broader influences on child development.

Animal Studies of Attachment: Lorenz and Harlow

• Lorenz (1935): Studied imprinting in geese, suggesting an innate attachment mechanism.
• Harlow (1958): Investigated attachment in rhesus monkeys, demonstrating that comfort is more important than food in forming attachments.

Supporting and Contradictory Studies on Animal Attachment

• Guiton (1966): Studied imprinting in chicks, confirming the critical period for imprinting.
• Schaffer and Emerson (1964): Suggests attachment in human infants is based on responsiveness rather than feeding.

Evaluation of the Animal Studies

• Strengths:

  • Significant theoretical contribution, challenging learning theory and informing understanding of emotional security.
  • Practical applications in animal welfare and institutional care practices.
  • Relatively controlled methodologies when compared to human studies.

• Limitations:

  • Species differences make generalising findings to humans problematic.
  • Ethical concerns associated with causing distress in animals.
  • Reductionist views that ignore the influence of environmental and social factors.

Learning Theory of Attachment

• This theory suggests infants form attachments primarily through conditioning in response to feeding.
• Classical conditioning: associate caregiver (neutral stimulus) with pleasurable feelings (unconditional response), to produce a learned response.
• Operant conditioning: when an infant cries to reduce discomfort, feeding resolves the discomfort - this reinforces the behaviour (negative reinforcement)
• Drive reduction theory: hunger is a primary drive, and attachment is a secondary drive, learned through association with food.

Supporting and Contradictory Studies on Learning Theory of Attachment

• Skinner's research on operant conditioning in animals.
• Dollard and Miller (1950): estimated feeding frequency to support the theory.
• Harlow (1958) and Schaffer and Emerson (1964) findings contradict this theory.

Evaluation of Learning Theory

• Strengths:

  • Early contribution to attachment research.
  • Offers testable predictions applicable to parenting strategies.
  • Scientific credibility from behaviourist research.

• Limitations:

  • Overemphasis on feeding, overlooking the role of emotional responsiveness.
  • Reductionist view of complex attachment behaviours.

Bowlby's Monotropic Theory of Attachment

• Bowlby's monotropic theory suggests attachment behaviours are biologically pre-programmed to ensure an infant's survival.
• Monotropy: Infants form a primary attachment to one special person, which is typically the mother.
• Critical period: Attachment is strongest during a critical period (up to 2.5 years).
• Internal working model: Infants develop a mental representation of relationships based on early experiences that shapes their expectations of future relationships.
• Social releasers: Infants are born with behaviours like crying and smiling to activate caregiving.

Supporting and Contradictory Studies on Bowlby's Theory

• Lorenz (1952): Demonstrated imprinting in geese, supporting the role of innate attachment mechanisms.
• Harlow (1958): Demonstrated that emotional comfort was more important than food in forming attachments, challenging the cupboard love theory.
• Rutter et al.: (Romanian Orphanage studies) highlight that recovery from early deprivation is possible, questioning Bowlby's concept of a critical period.

Evaluation of Bowlby's Monotropic Theory

• Strengths:
  • Important theoretical contribution, challenging learning theory.
  • Influence on childcare practices (e.g., emphasis on parental presence and consistent care).
• Limitations:
  • Overemphasis on the mother as the primary attachment figure (criticised for potential gender bias).
  • Reductionist focus on the mother-infant dyad (overlooks other important influences).
  • Critics argue that the theory is deterministic (presuming attachment patterns are irreversible).

Ainsworth's Strange Situation and Types of Attachment

• Ainsworth's Strange Situation (1978) aims to investigate attachment styles by observing infant responses to separation from and reunion with their parent, and interaction with a stranger
• Secure attachment: infants use the caregiver as a secure base, showing moderate stranger and separation anxiety, and are easily comforted upon reunion.
• Insecure-avoidant attachment: infants show little distress upon separation, avoid the caregiver upon reunion, and show little stranger anxiety
• Insecure-resistant attachment: infants display high levels of stranger and separation anxiety, and show resistance or ambivalence upon reunion.
• Disorganized/disoriented attachment: infants display contradictory and unusual behaviours, often associated with neglect or trauma.

Evaluation of the Strange Situation

• Strengths:
  • Standardised procedure, enhancing reliability and comparability across studies.
  • Predictive validity, as attachment types in infancy are associated with later social and emotional development.
  • High inter-rater reliability.
• Limitations:
  • Cultural bias, as the procedure was developed in the US and may not be equally applicable in other cultures.
  • Low ecological validity, as lab setting can influence behaviour.
  • Ethical concerns, raising questions about the level of acceptable distress to inflict upon the infants.

Cultural Variations in Attachment

• Van Ijzendoorn and Kroonenberg's (1988) meta-analysis of 32 studies found variations in attachment types across eight countries, despite universal patterns.
• Significant variations within cultures were greater than variations between cultures.
• Individualistic cultures (e.g., Germany) show higher rates of insecure-avoidant attachment (reflecting culturally valued independence).
• Collectivist cultures (e.g., Japan) displayed a higher rate of insecure-resistant attachment (reflecting a greater emphasis on close caregiver proximity).

Romanian Orphan Studies and the Effects of Institutionalisation

• Studies by Rutter et al. (1998, 2007, 2011) and Zeanah et al.(2005) assessed the long-term impact of institutions on children.
• Early adoption significantly improved developmental outcomes (lower IQ and disinhibited attachments in children adopted after 6 months), compared to those adopted earlier.
• Later adoption still showed difficulties in emotional and social development (e.g., lower IQ and disinhibited attachments), but the effects tended to be less severe compared to those adopted earlier.

The Influence of Early Attachment on Later Relationships

• Bowlby's internal working model (IWM) suggests that early attachment experiences form a cognitive framework for understanding relationships, shaping expectations of trust, intimacy, and security.
• Hazan and Shaver (1987) : investigated how attachment in early life effects later romantic relationships, and found that secure relationships were linked to happy and trusting relationships, while insecure-avoidant and insecure-resistant relationships were linked to mistrust and difficulty in close relationships.
• Kerns(1994): secure attachment predicted strong, stable friendships, while insecure attachment was linked to difficulty in maintaining friendships
