The experiential traces account claims that language comprehension in one's first language (L1) is based on the reactivation of experiential traces that stem from experiencing the corresponding objects, states, or events. However, it remains unclear to what extent this is transferable to second language (L2) comprehension. In the present study, we compared German L1 speakers with German L2 speakers whose L1 uses similar or different spatial terms as German. In an adaptation of the Stroop paradigm, participants were instructed to respond to the font color of German spatial prepositions (e.g., auf “on,” über “above,” and unter “under/below”) by either an upward or a downward hand movement, resulting in compatible or incompatible responses. We found significant compatibility effects for all speakers, but also clear differences between speakers of different L1s. The results thereby support the assumption that experiential traces built during L1 usage play an important role in L2 processing.

Embodied models of language comprehension are based on the assumption that words become associated with sensorimotor experiences during initial word learning. To test this hypothesis, adult participants learned artificial words as labels for novel objects in a multisensory environment. In a word learning phase, novel objects were located in the participant’s upper or lower visual field and participants learned the objects’ names by interacting with them. In a test phase, participants responded to the color of the words with either an upwards or a downwards directed arm movement in a Stroop-like paradigm. Responses were fastest when the movement direction was compatible with the word’s referent location (i.e., the location of the novel object in vertical space) during the learning phase. This finding suggests that sensorimotor experiences become associated with words during initial word learning. The results of the current study and implications for language learning are discussed.
