Abstract

In this study we examine the interactions between lexical and semantic variables during lexical decision. We replicate findings that semantically ambiguous words with related senses (polysemes) have an advantage in lexical decision. However, we report a reversal of the traditional concreteness effect, such that there is a disadvantage for words high in concreteness. Furthermore, we report an advantage for words high in context availability but note that this advantage is qualified by both contextual diversity and orthographic neighborhood frequency. In contrast to past findings, ambiguity and context availability did not interact, although a novel interaction of ambiguity and contextual diversity is reported. We discuss the implications of these findings for the context availability hypothesis (Schwanenflugel & Shoben, 1983).
