At birth, children were viewed as blank tablets to be written on it by their life events. Investigation reveals that newborns have genetic tendencies. Some basic wisdom does occur within the womb. Most experts now have the same opinion that the basis for learning begins much earlier than the actual birth. In the first trimester, the fetus's neural tube is just commencing to develop, so the brain is not fully operational. But according to Doctor Makoto Shichida, the answer can be found in the right brain hemisphere, also called the image brain. Psychologist William Fifer from Columbia University stated that newborns prefer their mother's voice to voices of other women. Once they tried electronically altering the mother's voice, so it would seem as it did when the child was in the womb. This sound is more favored than the mother's voice as it sounds outside the womb. This showed that fetuses were able to commit to memory the sound and "learn" it was harmless. This analysis was one of the first to show that babies are born with both a short and a long term memory. This study does not relate to the father's voice. It is advantageous that a father be just as involved as a mother during pregnancy, whether they"re reading to the baby, or just talking. Newborns show evidence of no difference in response to their father's voices as contrasted to other men's voices. But research has shown that a baby of 32 weeks not only have a preference for the mother's voice to all voices, but also acts in response to familiar songs and stories. It's significant to speak your baby in ways that you feel contented, such as reading books or singing your favorite songs. This certain type of music needs to make the mother happy when listening to it, which ever type music it may be. Infants are easily soothed by a familiar lullaby or story heard frequently while in the womb of them by one that is just been introduced.
