The term "mental template" has been used frequently by lithic analysts in recent years, especially in discussions of Lower Paleolithic bifaces and large cutting tools, of Middle Paleolithic stone tool typology, and of differences between Middle and Upper Paleolithic industries in Europe (e.g., Ambrose 1998; Ashton and White 2003; Barton 1990; Bisson 2001; Gowlett 1984, 1996, 2006; Marks, et al. 2001; McNabb, et al. 2004; McPherron 2000; Mellars 1996b; Monnier 2006, 2007; Nowell, et al. 2003; White and Dibble 1986). The concept is linked to a number of issues that are of special interest to Paleolithic archaeologists – modern cognitive abilities, style, symbolism, language, and the existence of cultural norms or emic categories.
