Question

At birth, we lack the ability to perceive, think, or use language because which area of our brain is not well developed?

a) Frontal lobe
b) Temporal lobe
c) Occipital lobe
d) Cerebellum

Answer 1

At birth, the frontal lobe is not yet fully developed, which affects the ability to perceive, think, or use language. The language function is primarily localized in the left cerebral hemisphere. Full development of the frontal lobes typically concludes by the age of 25.

Step-by-step explanation:

At birth, infants lack the ability to perceive, think, or use language because their frontal lobe is not well developed. The frontal lobe of the brain, which is responsible for actions such as reasoning, motor control, emotion, and language, including Broca's area that is essential for language production, continues its development after birth. In fact, the frontal lobes become fully developed by 25 years old. Additionally, the language function is predominantly localized in the left cerebral hemisphere for the majority of people. Hence, the lack of full development of the frontal lobe at birth restricts these cognitive abilities.
