There are regional differences in how archaeologists conduct their research on the Archaic period. The rich array of techniques and approaches used to examine this period in the West include human behavioral ecology and other evolutionary perspectives, technological style and aspects of practice theory, neuropsychological theory, and more. Recent research in the Great Basin, Southwest, Great Plains, Columbia-Fraser Plateau, and coastal California is surveyed to highlight commonalities and differences in the questions asked of the archaeological data and in the techniques that are used.
