AP PSYCHOLOGY

Detailed explanation-1: -Physical, such as fine motor skills (holding a spoon, pincer grasp) and gross motor skills (head control, sitting, and walking)

Detailed explanation-2: -As infants and toddlers grow, their determination to master movement, balance, and fine-and gross-motor skills remains strong. Rolling and crawling occur as infants develop skill in using large-muscle groups. Grasping and picking up objects with fingers are part of small-muscle growth.

Detailed explanation-3: -Physical Development. Physical development is divided into two areas, growth and development. Growth is the physical changes of, the increase in size, height and weight. Development is how children gain control over their physical actions to do complicated and difficult activities more skilfully and easily.

Detailed explanation-4: -Physical growth is especially rapid during the first 2 years. An infant’s birthweight generally doubles by 6 months and triples by the infant’s first birthday. Similarly, a baby grows between 10 and 12 inches in length (or height), and the baby’s proportions change during the first 2 years.

Detailed explanation-5: -Developmental Milestones Children reach milestones in how they play, learn, speak, behave, and move (like crawling, walking, or jumping). In the first year, babies learn to focus their vision, reach out, explore, and learn about the things that are around them.
