Do differences in behaviour imply a need for different psychologies?

Indigenisation movements are a most welcome development for two interrelate d reasons. The first is to make psychology relevant to non-Euroamerican soc ieties. The second reason is to show up the ethnocentricity in contemporary Euroamerican psychology, including cross-cultural psychology. The topics s tudied, the concepts and instruments used, and the inferences drawn in most behavioural research are centred on Western views and interests. However, it can be questioned whether the current literature on indigenisation serve s the societies for which it is intended much better than "traditional" cro ss-cultural psychology. The indigenisation literature seems to capitalise t oo much on cross-cultural differences in behaviour and to negate important invariances in psychological functioning across cultures. Such a one-sided emphasis is argued to be factually incorrect and theoretically misleading.
