One strength of caregiver-infant interactions
One strength is that the experiments were conducted under controlled conditions with detailed observations. Meltzoff and Moore filmed interactions between infants and caregivers to examine interactional synchrony. The use of video recordings allowed researchers to analyse the infants’ responses frame by frame, reducing the risk of observer bias.
-The high level of control ensures that findings are reliable and replicable, suggesting that caregiver-infant interaction studies provide accurate evidence about the role of early interactions in attachment formation.
One strength of caregiver-infant interactions
One strength is that it has led to real-world applications. Research on interactional synchrony and reciprocity has brought about parenting skills training, such as PCIT, whereby the caregiver and child have a 10-minute session that is shown to improve the quality of their bond. By applying the knowledge, caregivers can enhance the quality of attachment, leading to better social and emotional development in children. Therefore, research on caregiver-infant interactions has proven to have practical value.
One limitation of caregiver-infant interactions
One limitation is that infant’s behaviours may not be intentional or meaningful. For example, an infant sticking out their tongue or making facial expressions may not necessarily be a response to the caregiver, but could instead be random movements or reflexes. As researchers must observe this behaviour, it introduces the problem of subjectivity. Therefore, the validity of research on caregiver-infant interactions is reduced, as we cannot be certain that the behaviours observed are intentional social responses
One strength of stages of attachment
One strength is that it has high external validity. Most of the observations were made by parents during everyday activities. Babies were in their natural environment so they would not be anxious or behave differently based off their surroundings . This means their behaviour would be natural and researchers can therefore be sure that the findings are accurate and reliable.
One strength of stages of attachment
One strength is that it has good real-world application. It shows that babies in the asocial and indiscriminate stages can be cared for by any competent adult, but this is more difficult in the specific attachment stage. This helps inform parents/carers about when is the best time for babies to start day care, as starting at around 7 months (specific stage) can be very distressing for a young child. This can be used to help parents plan when to introduce their children to daycare, showing practical value.
One limitation of stages of attachment
One limitation is that it has poor generalisability. The children studied were a unique sample, in terms of cultural and historical context. They were all from Glasgow, of similar age, and from working class families. In other cultures, babies forming multiple attachments at a very early age is the norm, showing cultural variation in stages of attachment. This telling us little about stages of attachment in other eras or from other cultures, therefore lacking generalisability.
One limitation of stages of attachment
One limitation is there are issues with the mothers being the main observers. Mothers may find it difficult to be objective and clinical in their observations. They may have been biased in what they saw, have misremembered, or not noticed what their baby was doing. This means that even if the babies behaved naturally, their behaviour may not have been accurately recorded, reducing the reliability of the findings.
One strength of the role of the father
One strength is that understanding of the role of the father has practical applications for parenting. Research has influenced changed in parental leave policies, recognising that fathers play a crucial role in child development. Many countries now allow shared parental leave, enabling fathers to take a more active role in caregiving. Therefore, research into the role of the father has real-world benefits, influencing policies that encourage active father involvement in early childhood, which may benefit children’s emotional and social development.
One limitation of the role of the father
One limitation is lack of clarity over the question being asked. The question, ‘What is the role of the father?’ in the context of attachment is much more complicated than it sounds. Some researchers attempting to answer this question actually want to understand the role of fathers as secondary attachment figures, but others are more concerned with fathers as a primary attachment figure. This makes it difficult to offer a simple answer as to the ‘role of the father’. This is because it really depends what specific role is being discussed eg primary or secondary role.
One limitation of the role of the father
One limitation is that research into the father’s role may be influenced by social and cultural biases. Traditionally, Western societies have viewed mothers as the primary caregivers, which may have influenced early attachment research to focus more on the maternal attachment. This means that the research may reflect historical and cultural norms rather than biological differences in parenting roles. Therefore, findings on the role of the father may not be applicable universally.
One strength of animal studies
One strength is that animal studies have led to practical applications which improve the welfare of both humans and animals. Harlow’s research on maternal deprivation has helped inform workers in hospitals, orphanages and schools the importance of emotional care in early development. Including the introduction of ‘key’ worker systems in schools and nurseries whereby one worker is allocated to children, whom they are responsible for taking emotional care for and bonding with them. Therefore, showing how the findings from animal studies have led to a positive impact on human welfare, particularly in aiding early development.
One limitation of animal studies
One limitation is there are ethical issues and concerns when using animals. Harlow’s experiments, for example, caused severe distress to the monkeys and long-term psychological damage – of which influenced their ability to socialise, be parents and form relationships. While the findings of Harlow’s research were beneficial, the suffering caused to the monkeys raises conflict over the study. Therefore, although animal studies can be useful to understanding attachments today, it is questioned as to whether the ends justify the means.
One limitation of animal studies
One limitation is there are issues generalising animal studies to humans. For example, Lorenz’s study with geese showed that imprinting occurs over a critical period. But human attachment is far more complex than this as humans are far more cognitively developed. Whilst animal studies provide useful insights, they cannot be used to fully explain human attachment. Therefore, caution must be taken when applying findings like Lorenz’s study to humans.
One strength of the learning theory
One strength is support for the theory of operant conditioning resulting in formed attachments. Dollard & Miller argued that in a baby’s first year of life, they are fed 2000 times - generally by the main, consistent caregiver. This showing how the infant is given many occasions to associate the carer with the removal of the unpleasant feelings of hunger. This supports the idea that attachments are formed through operant conditioning, or through the process of ‘cupboard love’.
One limitation of the learning theory
One limitation is that behaviourist explanations are reductionist as they explain complex behaviours (like attachment) in a very simple way. The learning theory does not consider the internal cognitive processes or the emotional nature of attachments. They see babies as taking a passive role in attachment, rather than engaging in active roles such as reciprocity and interactional synchrony. This is a limitation as it does not take into consideration emotional factors in forming attachments in early life.
One limitation of the learning theory
One limitation is that the learning theory is not supported by animal research, such as that conducted by Harlow and Lorenz. Lorenz found that geese usually imprint before they are fed, and Harlow’s study showed that monkeys attached to the ‘mother’ that provided them comfort, rather than the one that fed them. These findings suggest that attachment is based on innate mechanisms and emotional security rather than food reinforcement, like the learning theory suggests. This shows how animal studies directly challenge the learning theory, weakening the theory that attachment is a learned behaviour based on reinforcement and association.
One strength of Bowlby’s monotropic theory
One strength is that there is support for the continuity hypothesis as correct. Bailey tested the idea that attachment can be passed down from one generation to the next. This was done by assessing 99 mothers’ attachment to their babies and comparing it to the mother’s attachment with their mother.
Findings showed that the mothers who reported poor attachments with their own mother, had a child who also developed a poor attachment. This is a strength for the internal working model as it proves that attachment types are passed down generations.
One strength of Bowlby’s monotropic theory
One strength is there is support for the theory of social releasers being crucial to a child’s ability to form attachments. Brazelton observed mothers and babies who showed interactional synchrony towards one another, resulting in the baby being content and communicative with their mother. It was also observed how babies react when the mother quits participating in interactional synchrony, resulting in the babies showing signs of distress and helplessness. This is a strength as it supports that mothers responding to the social releasers is crucial to forming a strong mother-child bond.
One limitation of Bowlby’s monotropic theory
One limitation is that Bowlby’s theories are socially sensitive. Monotropy is a socially sensitive idea as it has major implications for the lifestyle choices mothers feel they can make when their children are young. It has been pointed out that monotropy ‘sets women up to take the blame if anything goes wrong with their child’. This is a limitation as it suggests that the mother is at fault for anything that goes wrong with the child, or the attachment type developed.
One strength of types of attachment
One strength is that it has good inter-rater reliability. Researchers showed that different trained observers agreed on the attachment types found by Ainsworth 94% of the time – 80% being the minimum for inter-rater reliability to be valid. This is potentially due to the high levels of control in the experiment, and easily observable behaviours, making it more reliable. This is a strength because we can be sure the attachment types identified are not subjective, due to high inter-rater reliability.
One strength of types of attachment
One strength is that it has good predictive validity. Research has shown that a large amount of babies and toddlers assessed as type B tend to have better outcomes than others, particularly in childhood and adulthood. Such as, having better achievement in school, less involvement in bullying and greater mental health in adulthood. This suggests that the SS measures something real and meaningful in babies development.
One limitation of types of attachment
One limitation is that it is culture-bound. The SS was developed in Britain and the US. In a Japanese study, babies displayed very high levels of separation anxiety and so a disproportionate number were classified as type C. This is not because there are high rates of type C attachment in Japan, but because mother-baby separation is very rare in this particular culture. This meaning it may not be a valid measure of attachment in different cultural contexts.
One strength of cultural variations
One strength is that most of the studies were conducted by indigenous researchers. This means that the researchers came from the same cultural background as the participants.
This gives the study high validity as researchers and participants can communicate successfully. This is a strength because typical issues with cross cultural studies eg language barriers, are not a problem.
One limitation of cultural variations
One limitation is the impact of cofounding variables on findings. Studies conducted in different countries may not be matched for sample characteristics, such as using children of different ages or social class. As well as this, the environmental variables may differ also. This means that studies assessing attachment types carried out in different countries may tell us little about cultural differences in attachment .
