Judging other cultures by the standards and values of one's own culture. In its extreme form it is the belief in the superiority of one's own culture which may lead to prejudice and discrimination towards other cultures
The idea that norms and values, as well as ethics and moral standards, can only be meaningful and understood within specific social and cultural contexts
In 1992, 64% of the world's 56,000 psychology researchers were American. In Baron and Byrne's 1991 textbook on social psychology, 94% of the studies cited were conducted in North America
Despite having restricted their enquiries to particular parts of the world, many psychologists routinely claim to have discovered 'facts' about human behaviour that are 'universal'
Many argue that although psychology may claim to have unearthed 'truths' that say something about people all over the world, in reality, findings from studies only apply to the particular groups of people who were studied
Critics argue that mainstream psychology has generally ignored culture as an important influence on human behaviour, and by doing so, has mistakenly assumed that findings derived from studies carried out in individualist cultures can be straightforwardly applied all over the world
Classic social influence studies, originally conducted with US participants, revealed very different results when they were replicated in other parts of the world, for example Kilham and Mann (1974)
If the 'norm' or 'standard' for a particular behaviour is judged only from the standpoint of one particular culture, then any cultural differences in behaviour - that depart or deviate from this standard - will inevitably be seen as 'abnormal', 'inferior' or 'unusual'
A belief in the superiority of one's own cultural group. In psychological research this may be communicated through a view that any behaviours which do not conform to the (usually individualist) model are somehow deficient, unsophisticated or underdeveloped
Ainsworth identified the key defining variable of attachment type as the child's experience of anxiety on separation. She suggested that 'ideal' (or secure) attachment was characterised by the infant showing moderate amounts of distress when left alone by the mother-figure
This led to misinterpretation of child-rearing practices in other countries which were seen to deviate from the American 'norm' - for instance, German mothers were seen as cold and rejecting rather than encouraging independence in their children
Psychology has often been guilty of imposing an etic approach - arguing that theories, models, concepts, etc., are universal, when they actually came about through emic research within a single culture
The suggestion is that psychologists should be much more mindful of the cultural relativism of their research - that the 'things' they discover may only make sense from the perspective of the culture within which they were discovered - and being able to recognise this is one way of avoiding cultural bias in research
Critics have suggested, in this age of global communication and increased interconnectedness, that such a 'lazy' and simplistic distinction between cultures no longer applies
Yohtaro Takano and Eiko Osaka (1999) found that 14 out of 15 studies that compared the USA and Japan found no evidence of the traditional distinction between individualism and collectivism
Research (e.g. Ekman 1989) suggests that basic facial expressions for emotions (such as happiness or disgust) are the same all over the human and animal world
When conducting research in so-called 'Western cultures' the participants' familiarity with the general aims and objectives of scientific enquiry is assumed
Demand characteristics (always an issue within any investigation) may be exaggerated when working with members of the local population (Bond and Smith 1996) - and this may have an adverse effect on the validity of the research
