You can raise your eyebrows, i don't mind: are monolingual and bilingual infants equally good at learning from the eyes region of a talking face?

In this study we investigate whether paying attention to a speaker’s mouth impacts 15and 18-month-old infants’ ability to process visual information displayed in the talker’s eyes or mouth region. Our results showed that both monolingual and bilingual 15 month-olds could detect the apparition of visual information appearing in the eyes/mouth region but only 15month-old monolinguals and 18-month-old bilinguals could learn to anticipate its appearance in the eyes region. Overall, we demonstrate that specific language constrains (i.e., bilingualism) not only influences how infants selectively deploy their attention to different region of human faces, but also impact their ability to learn from them.
