- In the last few months of pregnancy, a fetus can hear sounds (the mother's voice, music, etc.)
- After birth, infants responded in a certain way when mothers read them a story that they had read to them during the 6 weeks prior to birth.
- This finding suggests that the infants recognized the story's pattern and tone—something they'd only been exposed to prenatally.
- Infants can hear immediately after birth, but a sound must be louder to be heard by a newborn than an adult.
- As infants age from 8 to 28 weeks, they become more proficient in localizing sounds.
- Infants are born with the ability to discriminate speech sounds from any language, but without constant exposure, they lose the ability by their first birthday.
