Background: Proficient speakers of a language often accommodate less proficient speakers during conversation to facilitate comprehension, but information about factors such as personality and language experience that may shape how speakers perceive accommodation is limited. Purpose: We developed an online questionnaire to clarify the use of speech accommodation in relation to individual differences in anxiety, personality, and English proficiency. Method: Using Qualtrics Panels for recruitment, we surveyed a representative sample of second-language (L2) English speakers (n = 201) and first-language (L1) English speakers (n = 192) across the United States. We report descriptive results in addition to correlations and a factor analysis to assess the perception of accommodation in L2 and L1 speakers. Results: Only a third of L2 participants reported that L1 speakers change their speech when talking to them, and more than half are frustrated when L1 speakers do not accommodate them. Indeed, a majority of our L1 participants reported that they do not change their speech when talking to L2 speakers. For both groups, measures of anxiety, personality, and L2 proficiency modify results, providing novel evidence on factors that influence L2 accommodation. Conclusions: Results suggest that L1 speakers accommodate L2 speakers less frequently than previously reported. The data are discussed under communication accommodation theory.
