Establishing neural representations for new word forms in 12-month-old infants.

During the first year of life, infants start to learn the lexicon of their native language. Word learning includes the establishment of longer-term representations for the phonological form and the meaning of the word in the brain, as well as the link between them. However, it is not known how the brain processes word forms immediately after they have been learned.

More efficient formation of longer-term representations for word forms at birth can be linked to better language skills at 2 years.

Infants are able to extract words from speech early in life. Here we show that the quality of forming longer-term representations for word forms at birth predicts expressive language ability at the age of two years. Seventy-five neonates were familiarized with two spoken disyllabic pseudowords.

Rhythmic structure facilitates learning from auditory input in newborn infants.

Rhythm and metrical regularities are fundamental properties of music and poetry - and all of those are used in the interaction between infants and their parents. Music and rhythm perception have been shown to support auditory and language skills. Here we compare newborn infants' learning from a song, a nursery rhyme, and normal speech for the first time in the same study.
