Question

The growth of the human brain is more rapid during ________ than at any other time.

A) the first year
B) the first four years
C) the first three years
D) the first five years

Answer 1

The growth of the human brain is more rapid during the first few years than at any other time. During this period, the frontal lobes, associated with planning, reasoning, memory and impulse control, grow rapidly. The brain undergoes synaptic pruning, eliminating unused pathways and making it more efficient.

Step-by-step explanation:

The growth of the human brain is more rapid during the first few years than at any other time. By the age of six, the brain has already attained about 90% of its adult size. During early childhood, especially from ages 3-6, the frontal lobes, which are associated with planning, reasoning, memory and impulse control, grow rapidly.

This period of rapid brain growth is followed by a process called synaptic pruning, where unused pathways are eliminated, making the brain more efficient.
