This paper proposes a model of how working memory capacity constrains a reader's ability to maintain multiple interpretations of a lexical ambiguity during reading comprehension. The model predicts that readers with a large working memory capacity (high-span readers) can maintain multiple interpretations of an unresolved lexical ambiguity longer than those with a small working memory capacity (low-span readers). In Experiment I, subjects read sentences in which a homograph was preceded by neutral contexts and disambiguated much later, as in Since Ken really liked the boxer, he took a bus to the nearest pet store to buy the animal. Consistent with the model's prediction, when the target homograph had one highly frequent meaning, high-span readers showed little effect of ambiguity on encountering the disambiguation, irrespective of which interpretation of the homograph (dominant or subordinate) turned out to be correct, suggesting that they had both interpretations readily available. In contrast, low-span readers showed a large ambiguity effect when the disambiguation was in favor of the subordinate interpretation, suggesting that they had only the dominant interpretation available. Experiment 2 showed that even mid-span readers were able to maintain multiple interpretations provided that the disambiguation occurred soon enough, further illustrating working memory constraints on ambiguity resolution. @ 1994 Academic Press, Inc.
