Which statement describes a research finding that demonstrates the functional lateralization of the brain that is involved in language processing? a. three-month-olds show greater activity in the left hemisphere when listening to normal speech than when listening to reversed speech or silence. b. newborns suck pacifiers more intensely to hear their mother's voice read a story, rather than a stranger read a story. c. sixth-month-olds can differentiate speech sounds of all the world's languages, but adults cannot do so. d. 12-month-olds prefer to listen to their native language than to a foreign language.

The correct answer is option  a. "Three-month-olds show greater activity in the left hemisphere when listening to normal speech than when listening to reversed speech or silence".

Explanation:

The functional lateralization of the brain is defined as the inclination of using one side of the brain in particular for certain neural functions or cognitive processes. Researches focused in demonstrating the functional lateralization of the brain study the activity of the hemispheres of the brain in people performing particular neural functions or cognitive processes. Therefore, an example of a finding in this regard is the following: three-month-olds show greater activity in the left hemisphere when listening to normal speech than when listening to reversed speech or silence.

it's not c. i took the quiz and got it wrong. so my best guess is b.

have a great day, and hope this .

answer: substrate concentration. enzymes work best when there is a high enough substrate concentration for the reaction they catalyse.
