Book excerpt: The encoding of motion event components is a central element in determining the nature of linguistic and conceptual representations underlying motion event construal. This work approaches the verbalization and conceptualization of motion events in German and English from a theoretical point of view and on the basis of a corpus study, an online survey, and an in-person experiment. The research focuses on the investigation of different factors determining motion event construal of native speakers and learners by examining cognitive variables – i.e., visual endpoint salience and cognitive cost caused by non-habitual aspect use – and grammatical factors – i.e., grammatical viewpoint aspect.
