Young children are going through a tremendous amount of growth in a very short period of time. Some very exciting and critical changes are happening in the brain that can have a long-term effect on a child. Researchers call specific timeframes for the developing brain during the first five to six years of life the "critical periods," "prime times," or "windows of opportunity." Like other milestones in young children's lives, including learning to walk, talk, and play with others, these "critical periods" are thought to be the best times for certain senses and skills to develop normally. Early experiences definitely play a key role in school success, which in turn will determine the highest academic level the child can achieve and the career opportunities.
Children's ability to learn language is stimulated and developed during the very early years through interaction, such as being talked and read to. Children are encouraged to speak when asked open-ended questions: "What do you think will happen next in the story?" Children surrounded with a variety of print and art materials, like books, newspapers,and magazines will likely to pick up reading habit at the early age. With the early develop of language skill, the child would be able to understand the school subjects taught to him or her, and cope better, with lesser stress. For example in mathematic, before solving the equation, we have to understand the problems first. The problems are usually presented in written language rather then symbols. So without a grasp of the language, it will be difficult to solve the equation.
Children develop social attachments to the people in their lives and learn to trust, feel safe, and have control over their emotions. This is the groundwork for the ability to be caring towards others. We have witness that children who are love and supported by their parents turn out to be emotionally balanced teenagers and adult. On the other hand, children who were abused, absence of parental care, often developed anti-social behaviour such as vandalism, and causing harm to others.
Childhood years laid the foundation of who we are today, especially in term of language development and social behavior.
