 Complicating matters, Bott (2008, 2010) applied the same norming procedures, but did not find evidence of coercion cost in iterative point action verbs in German. With other types of aspectual coercion, however, there were clear indications of processing difficulty indicating that the underlying processes differ between coercion types. Furthermore, the study provided evidence that at least in some cases (achievement ⇝ accomplishment) coercion operations are not triggered by an aspectual mismatch, but can proceed smoothly by enriching the aspectual representation with additional eventualities. This was shown in an event-related potentials (ERP) study in which a double dissociation of ERP components was elicited by sentences with aspectual coercion as compared to sentences that contained an aspectual mismatch.
