Assignment on The Infant lifespan process development
Part A
Lifespan development process in an infant is not merely a physical development but also
psychological development. Humans change their form and grow through the stages of
childhood, adolescence and adulthood. The development is a lifelong process that is proved with
scientifically theories. It has three developmental areas—physical, cognitive, and psychosocial
development. Physical development is all about bodily growth and changes in the brain, and
motor skills. Cognitive development means the child will start learning, pay attention, increase
memory, mastering language, developing reasoning, and creativity. Psychosocial development
means emotions, personality, and social relationships development (Corbetta, & Santello, 2018).

waste in form of potty. In four months the baby gains double the weight. The infancy is from
first to the two and a half year. A new born develops a strong sense of hearing but the vision is

36 inches in two years. In the first year the develop the walking skills, their grip will become
stronger and they will be trying to speak by listening to their surroundings (Haywood, &

Cognitive Changes
Cognitive changes means the method that the baby is learning to think, imagine,
remember and organize information, critical thinking and able to solve problems. These are
