What is MLU speech?
Mean Length of Utterance (MLU) reflects the average sentence length in words for a language sample. Mean Clauses per Utterance (MCU) obtained by identifying each main and embedded or subordinate clause and determining the average number of clauses per utterance for the entire language sample.
What is a normal MLU?
MLU Norms. Thanks again to Roger Brown, we know what to expect of a typically developing child with regard to their utterance length at different ages: 12-26 months: average MLU is 1.75 morphemes, with a range from 1.0 to 2.0. 27-30 months: average MLU is 2.25, with a range from 2.0 to 2.5.
How do you calculate MLU speech?
One you have a document with just the child’s utterances, go to Tools —> Word Count. Step Three: Divide the number next to Words (113 in this example) by 50 (the total number of utterances). This calculation gives you an MLU of 2.26.
What is the average MLU for a 5 year old?
5.63
At 4 years old expected MLU is 4.4 morphemes, at 4 years 3 months expected MLU is 4.71, at 4 years 6 months expected MLU is 5.02, at 4 years 9 months expected MLU is 5.32 and at 5 years expected MLU is 5.63 (Miller & Chapman, 1981).
How do you explain MLU to a parent?
For example, when children are first learning to talk, their MLU is often 1 because they only use one word at a time: “ball?”, “mommy”, “mine”, “no”. If uses a single word like this about half of the time but puts two words together the other half of the time (like “my ball”), then we would say the MLU is 1.5.
What should a 6 year olds MLU be?
A 6-year old’s speech should be understood by a stranger 90%-100% of the time.
What is the MLU of a 10 year old?
Language development in children 10-11 years: Children at this age can prioritize, organize, plan, report, and summarize effectively. Their writing is more complex than their conversational language. They also tell jokes using more complex language and ideas.
What does low MLU mean?
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. Mean length of utterance is a good marker of language impairment.
What is the average MLU for a 7 year old?
Your child should also be producing sentences with an average length of 4.5 words/morphemes or more.
What MLU should an 8 year old have?
However, by age eight, kids should be coordinated enough to skip, jump rope, and ride a bicycle. Children should also be able to throw a ball and hit a target about 5 feet away fairly consistently. (Of course, it helps that their vision is now fully developed by this age!)
What is the average MLU for a 6 year old?
What does a high MLU mean?
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.
Why is MLU important?
MLU is also a valuable index in investigations of children with language impairments. In clinical applications, MLU is used to diagnose language impairments in young children, often defined as an MLU level one standard deviation or more below the mean for the child’s age level (Eisenberg, Fersko, & Lundgren, 2001).
Is MLU syntax or morphology?
Mean Length Utterance (MLU) is a quantitative measure for morpho-syntactic complexity. It indicates how many morphemes or words a child uses per utterance. In other words: a higher value of the MLU means that a child is capable of producing more complex sentences.
Does MLU measure morphology?
The results from the MLU sections will be analyzed together with the scores obtained in three more scales: vocabulary, nominal inflection, and verb morphology. In the vocabulary and morphology sections, informants were asked to tick the items their child had started producing.
Is MLU a measure of syntax?
MLU is a useful method of measuring syntax in children who have not yet acquired complex sentences. All these scales should be adapted before they can be used in other languages.
How do you use MLU?
If a child says “my ball”, that’s two morphemes (my and ball). But if the child says “my balls”, then we would say she used three morphemes (my, ball, and “s”). If you were counting by number of words, both children would have the same MLU.
