ABSTRACT
This chapter presents a survey on what know about bimodal bilinguals, the linguistic competence and its evolution, about their monolingual production and their mixed production, both from a more experimental and psycholinguistic point of view and from a more theoretically oriented perspective. Since bimodal bilinguals code-switch, while unimodal bilinguals do, it is reasonable to assume that code-blending is what code-switching looks like when the usual articulatory constraint imposing just one channel is suspended. However, the independent types of blends that we have discussed in the preceding section are more difficult to analyze under this view, since they seem to involve more than just double vocabulary insertion. Bilingualism, referring to competence in two languages, is a widespread phenomenon, almost universal across language communities all over the world. Bilingual individuals and their linguistic competence have long attracted the attention of researchers in linguistics and in psycholinguistics.
