What is the relationship between MLU and chronological age?

There is a high correlation between MLU and chronological age of the child. This is partly due to the child’s increase in working memory (short term memory) as they get older allowing for sentences to be longer. A longer sentence has a better chance of having more morphemes.Click to see full answer. Accordingly, why is MLU important?MLU is important because if a child says “my toy,” that’s two morphemes. If the child says “my toys” then the child used three morphemes. If you were counting by the number of words the child used, they both used two, however the child who added the “s” made the utterance more linguistically complex.Beside above, how is Brown’s MLU calculated? Add the number of morphemes for all 100 utterances to give a total number of morphemes used. Divide the total number of morphemes used obtained in step 3 above by 100 to get the mean length of utterance. The -s plural marker (e.g. cat-s, dog-s). Count it even when used on irregular plurals (e.g. mouse-s). Similarly, how do you calculate MLU in words? Mean length of utterance (or MLU) is a measure of linguistic productivity in children. It is traditionally calculated by collecting 100 utterances spoken by a child and dividing the number of morphemes by the number of utterances. A higher MLU is taken to indicate a higher level of language proficiency.What are Brown’s stages 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.
