Cross-cultural psychology is differentiated from cultural psychology, which refers to the branch of psychology that holds that human behavior is significantly influenced by cultural differences, meaning that psychological phenomena can only be compared with each other across cultures to a very limited extent. In contrast, cross-cultural psychology includes a search for possible universals in behavior and mental processes. Cross-cultural psychology "can be thought of as a type [of] research methodology, rather than an entirely separate field within psychology".[6][7]
