outline research that supports the idea of interaction synchrony
Isabella (1989) observed 30 mother and infant relationships, and found that high levels on interactional synchrony were associated with more secure mother-infant attachments, suggesting interactional synchrony is an important caregiver-infant interaction
outline research that contradicts the idea of interactional synchrony
Le vine et al (1994) found that Kenyan mothers had little physical contact or interactions with infants however a high proportion of infants formed secure attachments
- shows interactional synchrony is not seen in all cultures and is not necessary for attachments to form
give two weaknesses of research into caregiver-infant interactions
- infants cannot talk to researchers must make interpretations about their behaviour - subjective approach which may lead to inaccurate conclusions being drawn - for example some behaviours may be random and not intentional
- research is often correlational as it is not ethically possible to manipulate interactions between caregivers and their infants so it is difficult to conclude causeandeffect between attachment and caregiver-infant interaction (eg whether specific interactions lead to a secure attachment, or if a secure attachment causes specific interactions)
outline the method of Schaffer and Emerson's research into the stages of attachment
- they studied working class mothers and babies, observing them each month for the firstyear of the baby's life, and again at 18months
- attachment was measured by looking at separation protest, eg when the infant was left alone in its cot at night AND stranger anxiety when the researcher approached the child, levels of distress were recorded
- interviews were also conducted with the mothers, including questions like who the infant smiled at and what caused them distress
give 2 strengths for Schaffer and Emerson's research into the stages of attachment
- high mundane realism - researchers used observations and interviews which allows the infants and their mothers to be studied in their everyday life environments, increasing the ecological validity of the study
- longitudinal design allowed for the same infants and their mothers to be studied over a period of time, reducing individual differences which increases the internal validity of the study
give 2 weaknesses for Schaffer and Emerson's research into the stages of attachment
- lacks temporal validity - conducted in 1964 and the way babies are raised has changed greatly from the 20th to the 21st century, eg fathers are more involved, grandparents live further away and nannies/childcare facilities are more common outside of upper class families, attachment formation may have changed
- sample is unrepresentative of the general population - all the participants in the research were working class glasweigan mothers, the way in which infants were raised may vary between classes and environments
outline the traditional role of the father in attachment
- the father is the 'breadwinner' of the family, typically working full time whilst the mother provides care to the children
- the father was seen as less important in attachment formation, as the mother was the primary caregiver due to biological factors (eg mother would traditionally breastfeed)
outline Field's research (1978) on the role of the father in attachment
- studied 4 month old babies interacting with their caregivers
- found fathers who were the primary caregiver spent more time displaying attachment formation behaviours with the infant than fathers who were secondary caregivers
- suggests it is not the gender of the caregiver that affects attachment formation, but behaviour displayed AND sensitive response to infants is not an innate biological response in women only
outline Grossman's research (2002) on the role of the father in attachment
- performed a longitudinal study looking at both parents behaviours with the child and the relationship to quality of attachments in adolescence
- found that the quality of mother-child attachment was important when assessing the quality of attachment into adolescence, but this was not the case for father-child attachment, suggesting the role of the father is less important.
outline the procedure of Lorenz's (1935) study of attachment in animals
- lorenz randomly split a clutch of goose eggs into two conditions, naturally reared by their mother OR incubated, where the first large moving object seen was lorenz
- goslings were later marked to show which group they belonged to and placed under an upturned box
outline the findings of Lorenz's study of attachment in animals
- immediately after birth, the naturallyreared goslings followed their mother, and the incubated goslings followed lorenz
- once released from the upturned box, the same pattern was seen and this effect was irreversible
- imprinting only occurred within the 'critical period' between 4 to 25 hours
- showed that goslings would imprint on the first large moving object that they saw, and would try to keep close contact with this object, showing attachment is innate and irreversible
how can evolutionary theory be used to explain imprinting
- baby animals (often prey animals such as birds) imprint on the first large moving object they see
- in nature this is usually the mother, meaning they would constantly be in close proximity to their mother, who could protect them from possible danger such as predators
give 2 strengths of Lorenz's study of attachment in animals
+ supported by the idea of sexual imprinting (irreversible)
+ practical applications - eg in agriculture if a lamb is orphaned and another ewe has lost its own young, fur from the dead young can be tied to the orphaned lamb and imprinting/attachment can occur through scent, so the orphaned lamb will be raised by the ewe
give 2 weaknesses of Lorenz's study of attachment in animals
- attachment in geese may not be the same as in humans - lorenz' conclusion ignores the complexities of human cognition that may be more advanced than those of geese
- Guilton (1966) found that chickens who sexually imprinted with a rubber glove eventually showed a preference for mating with chickens, suggesting imprinting is not irreversible as lorenz said
outline the findings of Harlow's research of attachment in monkeys
- monkeys preferred the cloth mother over the wire mother, some staying there for up to 22 hours a day and clinging onto the cloth mother while feeding from the wire mother
- monkeys with ONLY the wire mother had diarrhoea which was a sign of stress
- when frightened by the machine, monkeys would cling to the cloth mother
- in the larger cage, monkeys raised by the cloth more were more explorative, using the mother as a 'safe base' to explore from
- this showed that the availability for comfort in rhesus monkeys was more important in forming attachments than the availability of food, and this comfort was associated with lower levels of stress
give 2 strengths of Harlow's research of attachment in monkeys
+ laboratory experiment used, meaning standardised procedures and a highly controlled environment allowed the experiment to be easily replicated, increasing the internal reliability
+ practical applications - as rhesus monkeys are similar enough to humans to generalise the findings to humans this research has been crucial in helping social workers understand child abuse or neglect, and intervene to remove children from harmful environments
give two weaknesses of Harlow's research of attachment in monkeys
- extraneous variables may have become confounding - the two surrogate mothers looked completely different facially, with the towelling mother looking much more natural, which may have caused the monkeys to prefer it
- ethical issues - extreme lasting psychological damage was seen in the monkeys (in adulthood were aggressive and neglectful towards their young, some even killing them) as a result of the severely cruel nature of the experiment, which may to some outweigh the practical applications
outline the learning theory of attachment (Pollard & Miller)
- infants do not have an innate tendancy to form attachments, however they are developed through classical and operant conditioning because of a need for food
OPERANT CONDITIONING - when the baby is hungry, caregiver gives the baby food which removes the negative stimulus of hunger (negative reinforcement) food is the primary reinforcer and the caregiver bringing the food is the secondary reinforcer
CLASSICAL CONDITIONING - baby learns to associate the mother (the neutral stimulus) with food (unconditioned stimulus) which provides an conditioned response of being happy when the mother is near
outline one weakness of the learning theory of attachment
— there is contradictory evidence from animal studies. For example, Harlow demonstrated that contact comfort was more important than food in the development of an attachment, where the baby monkeys formed a primary attachment to the cloth-bound mother, regardless of which mother was dispensing milk. This suggests that there is no unconditioned stimulus (of food) and even if there is, it has very little influence upon the formation of attachments.
give 2 strengths of Bowlby's monotropic theory of attachment
- Bailey (2007) supports IWM - observed 99 mothers and their 1 year old babies on quality of attachment - found mothers who reported their own attachment with their mother as poor showed poor attachment to their babies supporting IWM
- Lorenz (1935) supports evolutionary theory - found certain animals have an innate tendancy to respond to various stimuli immediately and consistently - often displayed by a parent - will follow anyone displaying such stimuli - attachment provides an evolutionary advantage as baby animals are protected from harm by following parents - adaptive attachments
give 3 weaknesses of Bowlby's monotropic theory of attachment
- evidence from schaffer and emerson (1964) contradicts monotropic theory - found in stages of attachment that multiple attachments are the norm BUT often one primary attachment figure
- sociallysensitive theory - idea of monotropy places pressure on mother to be primary caregiver, may feel guilty for returning to work
- disregards research into role of the father - field (1978) found fathers that spent more time with infants could be primary caregiver
what is meant by 'adaptive' in bowlby's monotropic theory
attachments give humans an adaptive advantage, making us more likely to survive - if an infant has an attachment to a caregiver they are kept safe, warm and given food
what is meany by 'social releasers' in bowlby's monotropic theory
babies have social releasers, which 'unlock' the innate tendency of adults to care for them - these can be either physical (the facial features of a baby) or behavioural (crying, cooing, gripping on to things)
- relationship between mother and baby is reciprocal
