In two studies, we propose, refine, and test a new model of inferred motive predicting of individuals' reactions to nonaccommodation, defined as communicative behavior that is inappropriately adjusted for participants in an interaction. Inferring a negative motive for others' problematic behavior resulted in significantly less positive evaluations of both the interaction and the speaker than inferring either a positive motive or a lack of intentionality. It was also found that underaccommodation is consistently evaluated less positively than overaccommodation, likely due to inferred motive. In light of this, important amendments to communication accommodation theory's principles are suggested, and implications for future research are discussed.
