ManyBabies1: Quantifying sources of variability in infancy research using the infant-directed speech preference

Description

Research has shown that babies and young children pay more attention to speech with higher pitch and exaggerated intonation. This kind of speech is sometimes called child-directed speech, motherese, or baby talk. Evidence suggests that child-directed speech can help early language learning, e.g. by helping babies learn words and phrases, or by helping them realise that the speaker is talking to them, rather than to someone else in the room. The aim of the project is to understand the strength of this effect, how it might vary between babies, between languages and cultures, and how it might change as babies grow.
