AP PSYCHOLOGY

Detailed explanation-1: -In the first year, babies learn to focus their vision, reach out, explore, and learn about the things that are around them. Cognitive, or brain development means the learning process of memory, language, thinking, and reasoning. Learning language is more than making sounds (“babble”), or saying “ma-ma” and “da-da”.

Detailed explanation-2: -For the first month after birth, an infant is called a newborn. A newborn has a distinctive appearance. The head is very large, and the arms and legs are relatively short.

Detailed explanation-3: -The first year after birth is called infancy, after which childhood begins. Infancy is a period when the baby grows very fast. During the toddler stage, growth is still fast, but not as fast as it was during infancy. A toddler learns many new words.

Detailed explanation-4: -The term infant is typically applied to very young children under one year of age; however, definitions may vary and may include children up to two years of age. When a human child learns to walk, they are called a toddler instead.
