Obstetric ultrasonography, or prenatal ultrasound, is the use of medical ultrasonography in pregnancy, in which sound waves are used to create real-time visual images of the developing embryo or fetus in the uterus (womb).
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]
Phonological development refers to how children learn to organize sounds into meaning or language during their stages of growth. Sound is at the beginning of language learning. Children have to learn to distinguish different sounds and to segment the speech stream they are exposed to into units – eventually meaningful units – in order to ...
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 ...
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.
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 . Some research has shown that the earliest learning begins in utero when the fetus starts to recognize the sounds and speech patterns of its mother's ...
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.
Environmental toxicants and fetal development is the impact of different toxic substances from the environment on the development of the fetus. This article deals with potential adverse effects of environmental toxicants on the prenatal development of both the embryo or fetus, as well as pregnancy complications .
