摘要：In the context of the embodied cognition debate, an effect of motion verb associated speed information has previously been detected using eye-tracking, functional magnetic resonance imaging (fMRI), and reaction times (RT). The latter, for instance, was implemented by Wender and Weber (1982), who observed that participants were faster in detecting motion in sentences associated with fast motion compared to sentences associated with slow motion after having formed mental images of the sentences' content. It remains open whether the reported effects of speed are associated with automatic lexical-semantic retrieval processes or whether they reflect higher top-down cognitive processes. To answer this question, the paradigm by Wender and Weber (1982) was adopted and further elaborated in the present study. In Experiment 1 visualization instructions were eliminated. Additionally, the stimulus material was manipulated in regards to the agent of the described movement (human vs. object motion) in order to determine the representation's modality (visual vs. motoric). In Experiment 2, the task to detect motion was replaced by the task to judge sensicality. The results suggest that the prompt to perform mental imagery is not a precondition for the engagement of modal representations in this speed of motion paradigm and that the involved representations' modality is visual rather than motoric. However, the modal representations' involvement is dependent on the task. They thus do not seem to be part of the invariant semantic representation of manner of motion verbs.
