Infants exposed to language from utero
Babies show preference for previously read stories by sucking thumb
Infants prefer vocalisations to artificial sounds - (Voluloumanos et al., 2010)
Newborn infants (47 hours old) will prefer human sounds over synthetic voice sounds
Human voices and monkey vocalisations
By 3 months of age infants prefer human vocalisations

Specialisation in language
As children get older they can’t respond to phonemes to all languages and will specialise to their own language
Cry, cough, sneeze

Vocalisations vary with age and individuals
Number of vocalisations increase over time although there is variance within a group
Universality of babbling

- Deaf babies babble with sign language
Babbling predicts later language development
Oller et al. (1998) found late canonical babbling predicted developmental delay
