Experimental Design and Experimental Inference in Stone Artifact Archaeology

Lithic researchers rely heavily on experimentation to infer past behaviors and activities based on stone artifacts. This paper explores the analogical nature of archaeological inference and the relationship between experimental design and inference validity in stone artifact experimentation. We show that actualistic flintknapping lacks vital aspects of scientific experimentation, and thus has inherent inferential issues of analogical adequacy and confidence. It is argued that a greater emphasis on hypothesis construction and variable control is needed in order to establish sound referential linkages upon which constructive analogic inferences about the past can be built.     

Middle paleolithic scraper reduction: Background,clarification, and review of the evidence to date

The hypothesis that the principal varieties of Middle Paleolithic scrapers reflect varying degrees of resharpening and rejuvenation, rather than discrete emic types, has generated considerably controversy over the past decade. While there have been certain misunderstandings surrounding the proposed models of scraper reduction, this controversy also reflects different approaches taken by prehistorians in interpreting lithic artifacts. Placing the notion of scraper reduction in the context of lithic processes generally known as the Frison Effect, this article presents the background and intellectual context of this interpretation and attempts to clarify the models themselves and their test implications. It also reviews and summarizes data generated by several independent tests of the hypothesis and presents new data bearing on this question.
