Discipline: Psychology
Cross-cultural psychology is concerned with behavioral similarities and differences across groups which are rooted in some features of these groups’ cultures and ecologies. The sampling strategy therefore consists of choosing groups on the basis of differences, established or hypothesized, and of looking into cultural/ecological features of interest which are hypothesized to affect behavior across these groups differentially (or similarly, as the case may be, i.e., despite the apparent differences in hypothesized behavioral antecedents). Not at all surprisingly, the groups that are chosen for study in a cross-cultural psychological investigation usually come from different countries. Indeed, cultural/ecological dimensions of interest usually take different levels across geographical areas separated by country lines.
