Comparing Global and Local Accommodation: Rating and Response Time Data

Abstract

This paper addresses the question to what extent global and local accommodation should be viewed as sharing the same underlying mechanism or whether they are distinct processes that only happen to share the same label. We present offline rating data and response times from a mouse-tracking experiment that directly compared global and local accommodation for five different triggers. The results show that globally accommodating a presupposition led to a larger decrease in acceptance than locally accommodating, and that response times for local accommodation were overall faster. While we take the results to be inconclusive with regard to the question about the underlying mechanism, we conjecture that the contexts tested here were more favorable for local accommodation, and that hence investigating how different contexts affect the relative ease of accommodation type is a promising avenue for future research.
