Language and communication skills are critical to a child’s development. Good communication makes them better able to engage in socialization and to learn from their environment and from formal classroom instruction. When we talk about communication we are talking about both speech which is the verbal means of communication and language which is using shared rules to put words together to express thoughts and feelings as well has to understand the meaning of language through both spoken and written communication. Since parents are a child’s first teacher, knowledge of language development in children improves their ability to interact with their child to stimulate and guide them in their ability to understand and communicate with their environment.
There are four main components of language:
- Phonology involves the rules about the structure and sequence of speech sounds.
- Semantics consists of vocabulary and how concepts are expressed through words.
- Grammar involves two parts. The first, syntax, is the rules in which words are arranged into sentences. The second, morphology, is the use of grammatical markers (indicating tense, active or passive voice etc.).
- Pragmatics involves the rules for appropriate and effective communication. Pragmatics involves three skills:
- using language for greeting, demanding etc.
- changing language for talking differently depending on who it is you are talking to
- following rules such as turn taking, staying on topic
From birth on, children are programmed to develop speech and language. The first five years are most critical but language development continues throughout early childhood and on into adolescence. During the first five years stimulation of language development is important as the brain is both developing new nerve cells as well as multiple connections between nerve cells to serve the function of language both expressive and receptive. Lack of stimulation during this time could result in a child making slower progress or end up with poor communication skills. Later, we provide some tips for parents on how to help with language development but the basic suggestions are to spend lots of time talking, singing and reading to your child.
In the early stages of language development, the brain is programmed to attend to speech sounds and begin to mimic them. Early on babies like to make sounds up on their own. Later they attempt to repeat sounds/words that they are exposed to from their environment.
Children usually say their first words between nine and 18 months old. The most common first words are either “mama” or “dada’. What’s kind of interesting is no matter what language children are raised in, the first words usually reference either mother or father. By the age of 18 months a child usually has a vocabulary of 50 to 150 words.
By two they can probably use over 300 words and understand about 1,000 words. By about 18 months children begin to put a couple of words together to form a sentence sometimes referred to as “telegraphic speech” such as “Mommy ball” or “Mommy throw ball”.
Around 3 years of age, children begin to use language for all kinds of things. They are not only trying to get things by asking they are talking about past experiences and even beginning to use it to pretend. By preschool (4 ½) they are beginning to understand and use the rules of language to express possession of something, connect thoughts and quantify. There language is becoming more like that of adults.
In elementary school children continue to expand their use of oral language but are also learning to read a write. As children progress through middle school and high school they continue to expand their vocabulary and refining their grammatical skills and write in more complexities as well as continue to develop reading comprehension skills.
The tables below describe specific skill development for each stage of development through age 8. Below the developmental time line you will find information on how you can stimulate and encourage language development as well as information on how to recognize lagging development and what to do about it.
