Abstract We know little about the factors influencing which words we choose during lexical selection. In two experiments we investigated whether (re)activations of experiential traces of space have an impact on language production. Participants performed up- and downward head movements while listening to sentence fragments describing situations (e.g. ‘You are at the beach and you see…’). When reaching the upward/downward head position they completed the sentence with a freely chosen noun. A different group of participants rated the spatial location of the produced word’s referents. We found that the head movements influenced participant’s lexical choices. After upward movements the produced words were rated to be located higher up in space compared to downward movements. Furthermore, higher scores in interoceptive sensibility as measured using the attention regulation scale from the Multidimensional Assessment of Interoceptive Awareness questionnaire (Mehling et al., 2018) lead to an increased effect of head movement on the spatial properties of the produced nouns. We conclude that sensorimotor activations are among the meaning facets that guide which words we chose when speaking. The tendency to verbally express embodied meaning is enhanced with higher levels of interoceptive sensibility, suggesting that interoception may be a key to understand interindividual differences in how we express our experiences and feelings when we speak.
