    Författare :Yulia Kashevarova; [2023]
    Nyckelord :trilingual speech processing; cross-linguistic competition; sentence context; BLINCS; BIA ;

    Sammanfattning : Persistent non-target language co-activation in spoken and visual language comprehension has been found both at the word-level and at the level of a sentence, although in the latter case, sentence bias has been observed to modulate the co-activation which can create lexical competition. In the case of trilingual speakers, both non-target languages may potentially compete with the third language (L3). LÄS MER
