What are Brown’s stages?
These structures increase in complexity over time and are separated into stages, known as “Brown’s Stages.” Roger Brown identified these stages to help understand and predict typical expressive language development in children. Each stage has an age range (in months), an MLU range, structure types, and examples.
What are the final stages of Brown's model of language development?
The final stages of Brown's model are V and V+. The MLU ranges from 3.75 and up for children who are 41 months and over. Children in the last stages can use third person, contractions and indefinite forms such as "no one" and "nobody." Based in Pittsburgh, Erica Loop has been writing education, child development and parenting articles since 2009.

What is Roger Brown's theory of language development?
Roger Brown was an eminent social psychologist, best known for his studies in early linguistic development of children. He described five stages of language development, based on the mean length of utterance (MLU), which is the number of morphemes --- basic units of meaning --- toddlers can produce.
What is Brown's stage of language development?
Brown's Stages ("Brown's Morphemes") I to IV. As children's MLUm increases their capacity to learn and use grammatical structures of greater complexity increases. They move from Stage I into Stage II, where they learn to use "-ing" endings on verbs, "in", "on", and "-s" plurals. They then proceed to Stages III and IV.

The major conclusions drawn from the study were that most children, despite their retardation, acquired the majority of early morpheme rules. The first six rules in the sequence that Brown (1973) described, were also acquired first in the language of the children with Down syndrome.
What does Brown's research say about grammatical morphemes in children?
In a study of three children in the United States, Brown found that between the ages of 2 and 4 years, typically developing children gradually incorporated a variety of different morphemes in their speech.

How is Brown's MLU calculated?
Now, in order to find the mean length of utterance we take the total number of morphemes (17) and divide it by the total number of utterances (4). Thus, the mean length of utterance is 17/4 = 4.25.

What is a SLP?
A speech-language pathologist (SLP) will take a sample of a child’s expressive language and analyze it to determine the child’s MLU and will also refer to Brown’s Stages to identify where the child is in his or her language development.
