Accessing lexical ambiguity: Effects of context and dominance

Abstract

The paper examines the effects of sentential context and frequency of meaning (dominance) on the lexical access of ambiguous words. Two experiments were carried out using Swinney's (1979) cross-modal paradigm. The sentential contexts were constructed in such a way as to make salient the most characteristic features of either the dominant (Experiment 1) or the secondary (Experiment 2) meaning of the ambiguous word. The claim was that if context is sufficiently constraining selective access of the congruent meaning can be obtained. Consistent with this prediction, context biasing the dominant meaning facilitated lexical decision only on target words related to the dominant meaning. When context biased the secondary meaning, both context and dominance produced a facilitation effect.
