In communication, diverse forms of language combinations are possible for bimodal bilinguals, who employ a spoken and a signed language. They can either switch from one language to another (language switching) or generate a word and a sign concurrently (language blending). This inquiry explores language control mechanisms in language switching and simultaneous bimodal language production, comparing single-response (German or German Sign Language) and dual-reply trials (Blend of the German word and the German Sign Language sign). There were three pure blocks, one for each Target-response (German, German Sign Language, Blend), as well as mixed blocks, in which participants switched between all three Target-replies. The inquiry discerned language mixing costs, switch costs and dual-response costs. Farther, the data pattern displayed a specific dual-response benefit for switching into a Blend (i.e., a dual-reply trial), pointing out the specific nature of a blended reply in bimodal bilingual language production.
