Ainsworth's strange situation is a usefulresearchmethod which provides a lot of information about attachment. It had standardisedprocedure of fixedtimings for each stage and what occurred in each stage, making it easytoreplicate which led to a rapidincrease in the amount of research carried out into attachmentsvariations, within and between cultures. This increases the validity of the findings as supportingreplications can be done with similarresults each time. However, as it was a controlledobservation there may have been researcherbias.
Strange Situation: Cultural Bias
Ainsworth's strange situation was conducted in the USA and the following types of attachment were identified and constructed based on American cultural standards. Behaviour regarded as healthy in the USA may not be considered healthy in other cultures as they have different standards for child-rearing practices. For example, Japan has high levels of insecure-resistant infants due to high separation anxiety, but in this culture infants are not typically experienced in being separated. This means that it may be Eurocentric and subject to cultural bias.
Strange Situation: 4th Attachment Type
Ainsworth outlined 3 attachment types, however Main and Solomon later identified a 4th attachment type; the disorganised attachment type. It has also been criticised for oversimplifying attachment type, as in some cases infants have differed within a given category. This suggests that not all infants fit into the outlined attachment types by Ainsworth, questioning the validity.
