Expressive Language - Speaking
A child may have difficulty using language. They may have trouble putting words together in the right form or order (grammar) or knowing the appropriate name for things (vocabulary).
Receptive Language - Comprehension
A child may have difficulty understanding language; they may not understand what certain words mean or how they go together. As a result, they have challenges following directions or answering questions appropriately.
“Late talkers” may present with expressive language delays and/or receptive language delays. In determining if a child has a language, it is important to consider other language development factors, including the rate of vocabulary growth, emerging grammar, speech sound development, language comprehension, social language skills, use of gestures, and symbolic play behaviours.
Scientific evidence indicates that "Late talkers" may be at risk for developing language and/or literacy difficulties as they grow up. These language difficulties are much less likely to resolve as time passes. Studies indicate that children who receive intervention from a Speech-Language Pathologist are far better than those who do not.
Language Delay is the term used when language development trajectories are below age expectations.
This can be in the areas of speaking and understanding.
