Final answer:
The word "spy" was slower to be responded to in the second trial because, after the context clarified the meaning of "bug" to refer to insects, the activation of the related meaning ("ant") was maintained while the irrelevant meaning ("spy") was no longer activated leading to a slower response time for "spy".
Step-by-step explanation:
The lexical ambiguity study you're referring to investigated how context affects the processing of words with multiple meanings, such as the word "bug", which can refer to an insect (ant) or a covert listening device (spy). The reason why the word "spy" was not responded to as quickly in the second trial can be attributed to the context in which the ambiguous word "bug" was used. Initially, both meanings of "bug" were activated, hence the fast response time for both "ant" and "spy". However, once the context was clarified, only the meaning relevant to insects remained activated.
Option A is the correct explanation. During the first trial, the context had not been established, so the subjects responded quickly to both "ant" and "spy". By the second trial, the context made clear that 'bugs' referred to insects. As a result, the word "spy" was congruent with only one meaning of "bug" and was thus not activated. The activation of the contextually appropriate meaning ("ant") leads to faster response times for that word, while the now irrelevant meaning ("spy") led to slower responses.
