We explore the role of top-down information in language processing by investigating parallel language activation in bimodal bilinguals, who are fluent users of a spoken and a signed language. In an eye-tracking study, bimodal bilinguals showed activation of their signed language while receiving input in English only. Since spoken and signed languages do not share structure, the results suggest that linguistic information can be readily transmitted across modalities, and that parallel language activation can be driven by top-down processes.
