Insecure-Avoidant (Type A) attachment was found to be most prevalent in Western, individualist cultures. For example, Germany showed higher levels of avoidant behavior, which researchers attribute to cultural values that emphasize early independence and self-reliance.
Insecure-Resistant (Type C) attachment was more common in collectivist cultures. In Japan and Israel (specifically in Kibbutzim), infants showed higher rates of resistant behavior, likely because they are rarely separated from their mothers, making the Strange Situation particularly distressing.
These variations suggest that while the 'Secure' base is universal, the specific 'Insecure' adaptation depends heavily on what the local culture defines as competent or desirable behavior in a child.
One of the most significant findings was that intra-cultural variation (differences within a single country) was times greater than inter-cultural variation (differences between countries). This means that a single country like the USA might have sub-cultures with vastly different attachment distributions.
This finding cautions against over-generalizing about a whole nation's parenting style. It suggests that socio-economic status, urban vs. rural settings, and individual family dynamics often play a larger role than national identity.
Researchers concluded that it is more accurate to talk about 'cultural variations' rather than 'cross-cultural' differences, as the latter implies countries are homogenous units.
A major criticism of this research is the concept of Imposed Etic. This occurs when a technique designed for one culture (the American Strange Situation) is applied to another culture without modification, assuming the meanings of behaviors are the same.
For instance, in Germany, lack of proximity-seeking might be seen as 'independence' rather than 'avoidance.' In Japan, extreme distress upon separation might be a sign of a 'strong bond' rather than 'insecure-resistance.'
Furthermore, the samples used in the meta-analysis were often unrepresentative. For example, the data for China was based on a very small sample size, which may not accurately reflect the attachment patterns of over a billion people.
Focus on the 1.5x Rule: Examiners frequently test the distinction between intra-cultural and inter-cultural variation. Always remember that there is more variation within a country than between countries.
Link to Theory: When discussing why secure attachment is universal, link it to Bowlby's evolutionary theory (innate survival mechanism). When discussing variations, link them to environmental/cultural learning.
Use the Term 'Imposed Etic': This is a high-level evaluative term. Use it to explain why the Strange Situation might lack validity when used in non-Western contexts.
Check the Numbers: Be careful not to say 'all' Japanese children are resistant; instead, use phrases like 'higher proportions compared to Western samples.'
