Child development and dating

This led to Piaget develop four important stages of cognitive development: sensorimotor stage (birth to age 2), preoperational stage (age 2 to 7), concrete-operational stage (ages 7 to 12), and formal-operational stage (ages 11 to 12, and thereafter).Piaget concluded that adaption to an environment (behaviour) is managed through schemes and adaption occurs through assimilation and accommodation.[2] Sensorymotor: (birth to about age 2) This is the first stage in Piaget's theory, where infants have the following basic senses: vision, hearing, and motor skills.Child development entails the biological, psychological and emotional changes that occur in human beings between birth and the conclusion of adolescence, as the individual progresses from dependency to increasing autonomy.It is a continuous process with a predictable sequence, yet having a unique course for every child.Some deficiencies in this stage of development are that children who are about 3–4 years old often display what is called egocentrism, which means the child is not able to see someone else's point of view, they feel as if every other person is experiencing the same events and feelings that they are experiencing.However, at about 7, thought processes of children are no longer egocentric and are more intuitive, meaning they now think about the way something looks instead of rational thinking.Some age-related development periods and examples of defined intervals are: newborn (ages 0–4 weeks); infant (ages 4 weeks – 1 year); toddler (ages 1–2 years); preschooler (ages 3–5 years); school-aged child (ages 6–12 years); adolescent (ages 13–19).Another influential factor in a child's development is the quality of their care.

Because these developmental changes may be strongly influenced by genetic factors and events during prenatal life, genetics and prenatal development are usually included as part of the study of child development.
