Languages and developing language skills is very important for children and it will allow them to learn syntax of a native language and it helps to increase their vocabulary. Learning language are cognition seem to be strongly related to one another and if learning a language is delayed it could actually affect the ability of a child to learn concepts and develop spatial skills and other areas of cognitive development.
In one theory, it is thought that the environment will help to develop intellectual abilities and certain behaviors and how to make sense of how things work in the environment has huge influences on the development of the basics of thinking. So if there is no language in the environment the stages of cognitive development could be delayed and it might be hard for children to understand any kind of logical actions. Children as they grow older will start to learn through the operation of things or through logical manipulation like that of numbers, volume or the size of something.
Children will try and focus their attention on the sounds that surround them in their environment and language is one of those sounds that are around them. At an early age it is known that they can distinguish quickly between different languages and that is why it's a lot easier to teach a young child to be multi-lingual than it is an adult. It is their ability to use their cognitive skills of vision, touch and the sound around them that helps them with their linguistic development.
Children will learn their language or languages when they have interactions with their parents, other adults and other children. They will learn the correct inflections in the speech, changes in tone and the construction of speech all by listening to their environment. To develop language they need to be able to identify, sort and use memory skills. The are all cognitive areas that will all match when anyone starts to learn a language. When a child is able to build their linguistic skills, it will be far easier for them to interact with others.
When a child learns a language, which includes the words, they are also learning concepts. When a child use the word “dog” he also may point to that animal. But this does not mean the child has mastered their language it just means they are learning words because they may first start off calling everything a “dog” until they get it right.
Language is also needed when a child begins to orient themselves to a room through their spatial reasoning. Developing their language is going to help them with their spatial reasoning by helping them understand different spatial phrases like to the right or left or behind or in front of you. This is how your child can then figure out how to find their toy, or how far and in what direction they need ot go to reach the sofa or the table. All of these actions reflect upon how well the child has accomplished a cognitive task through the use of their language.
