Learning language as an infant also requires fetal memory. It is now known that the mother's voice is clearly heard from inside the womb and that the fetus can differentiate speech sounds, particularly the phonemes (a single segment of sound) in speech. This is evident in the baby when born, showing many signs of early language comprehension.
The presence of such chemicals as adenosine, pregnanolone, and prostaglandin-D 2 in both human and animal fetuses, indicate that the fetus is both sedated and anesthetized when in the womb. These chemicals are oxidized with the newborn's first few breaths and washed out of the tissues, increasing consciousness. [ 13 ]
Language development in humans is a process which starts early in life. Infants start without knowing a language, yet by 10 months, babies can distinguish speech sounds and engage in babbling.
Also, most low-frequency sounds (less than 300 Hz) can reach the fetal inner ear in the womb of mammals. [20] Those low-frequency sounds include pitch, rhythm, and phonetic information related to language. [21] Studies have indicated that fetuses react to and recognize differences between sounds. [22]
A study by Gathercole and Baddeley (1989) showed the importance of sound for early word meaning. [36] They tested the phonological memory of 4- and 5-year-old children, i.e., how well these children were able to remember a sequence of unfamiliar sounds.
Exposure to those toxins during pregnancy can create serious health issues in elementary school children that can affect their lives for years to come, a new study found.
New research suggests fluoride exposure during pregnancy could be linked to neurobehavioral issues in kids. But even the study’s authors — who were prompted to examine the issue based on ...
Children exposed in the womb to pesticides and synthetic chemical contaminants such as PFAS gain more weight during childhood, a new study says.
