Paul Rozin and Carol Nemeroff suggested that such thinking is not limited to traditional cultures but exists in some aspects of daily life in highly industrialized cultures as well. Cultural psychologists and cross-cultural psychologists tend to differ in their views about the usefulness of testing cognitive abilities across cultures. Cross-cultural psychologists have tended to believe that once adjustments are made to a cognitive abilities test it can be used effectively in a culture other than the one for which it was originally developed. Cultural neuroscience is a relatively new approach to studying culture and human behavior which became possible due to the mapping of the human genome and advances in brain imaging. A fascinating way to explore culture and perception is to examine aesthetic responses. A significant portion of cross-cultural psychology focuses on how to modify tests in order to make them cross-culturally appropriate.
