= difference in norms and values that exist between people in different groups.
Van Ljzendoorn and Kroonenberg research
= looked at proportions of secure, insecure-avoidant,insecure-resistant attachments across a range of countries to assess cultural variation.
In all countries secure attachment was most common. But varied from 75% in Britain to 50% in China.
in individualist cultures rates of insecure-resistant were under 14% but in collectivist cultures rates where above 25%.
variations between results of studies within the same country were 150% greater than between countries. eg: in USA one study found 46% securely attached compared to one sample as high as 90%.
Italian study
Simonelli conducted a study to see whether the proportions of babies of different attachment types matches those in previous studies.
researchers assessed 76 babies using strangesituation, found 50% were secure, 36% insecure-avoidant. This is a lower rate of secure and a higher rate of insecure-avoidant attachment than in other studies.
suggests this is because increasing numbers of mothers of very young children work long hours and use childcare.
Korean study
=to compare the proportions of attachment types in Korea to other studies.
Overall proportions of insecure and secure babies were similar to those in most countries, with most being secure.
Distribution is similar to the distribution of attachment types found in Japan
Since Japan and Korea have quite similar child-rearing styles so this similarity might be explained in terms of child rearing style.
conclusions
= secure attachment seems to be the norm in a wide range of cultures, supporting Bowlby's idea that attachment is innate and universal and this type is the universal norm.
but cultural practices have an influence on attachment type.
Evaluation- indigenous researchers
strength= most studies were conducted by indigenous psychologists.
indigenous psychologists are those from the same culturalbackground as the participants.
So this means that many problems in cross-cultural research can be avoided, such as researchers misunderstanding of the language used by participants or having difficultycommunicatinginstructions to them. Difficulties also include bias and stereotypes.
so good chance that researcher and participants communicated successfully- enhancing the validity
Evaluation- counterpoint
However this is not true of all cross-cultural attachment research.
their data might have been affected by difficulties in gathering data from participants outside their own culture.
so data from some countries might have been affected by bias and difficulty in cross-culturalcommunication.
Evaluation- confounding variables
Studies conducted in different countries are not usually matched for methodology when they are compared in reviews or meta-analyses.
samplecharacteristics such as poverty, socialclass and urban/rural make up and age can confound results.
environmental variable eg: size of the room+ the availability of interestingtoys there- babies might appear to explore more in studies in small rooms with attractive toys rather than largebare rooms.Less visible proximity seeking because of room size.
don't tell us tell much about cross cultural patterns of attachment
Evaluation- imposed etic
limitation= trying to impose a test designed for one cultural context to another context.
Imposed etic occurs when we impose an idea or technique that works in one cultural context to another. Eg: use of babies response to reunion to caregiver. In Britain and USA, a lack of affection on reunion may indicate an avoidant attachment. But in Germany such behaviour would be interpreted as independence.
so behaviours measured by strange situation may not have same meanings in different cultural contexts and comparing them is meaningless.
