Hearing During Infancy and Toddlerhood
Hearing begins developing before birth. Fetuses respond to sounds in the womb through changes in brain activity, heart rate, and body movements, showing sensitivity to auditory stimulation. After birth, hearing continues to develop rapidly, supporting language learning and environmental awareness.Auditory Acuity and Sound LocalizationAuditory acuity refers to the ability to detect sounds. Newborns are especially responsive to human voices and can detect many speech sounds, although their...
Perceiving Language Sounds and Structure During Infancy
Infants are born with a predisposition to perceive and categorize basic linguistic sounds. Early in development, they can discriminate sounds from many languages and detect differences in rhythm and pattern. This sensitivity may begin before birth. Newborns exposed to two languages prenatally can recognize both, indicating that fetal language exposure influences later auditory discrimination.Recognition of Familiar SoundsBy five months, infants show preferences for familiar auditory stimuli,...
