Cross-cultural research can provide a useful insight into cultural differences in gender roles and therefore the potential role that media has to play. Mead (1935) who found that within the same island of New Guinea, there were significant differences in the gender roles and temperaments of several tribes, such as the Arapesh and the Mundugumor. Therefore, gender may not entirely be biologically determined, but we are simply biologically predisposed towards identifying with one gender rather than the other, and this can be influenced by culture and media.
