Hi, Diane,
<div><br>
</div>
<div>Repetitions and other types of "mazes" (false starts, interjections, self-corrections) are typically not included as countable utterance for MLU calculation, although it may be included in some types of analyses depending on your goal. There are some pretty
good papers that describe principled ways of chunking spoken language into analyzable units. Here is one (but there may be better ones - if you would like, I can take a look and send you more references): Foster, P., Tonkyn, A., & Wigglesworth (2000). Measuring
Spoken Language: a Unit for All Reasons, Applied Linguistics, 21/3, 354-375.</div>

<div dir="ltr">Dear all,
<div>I would be very interested in knowing how you treat self-repetitions for various types of analyses, especially MLU.</div>
<div><br>
</div>
<div>In particular, I'm thinking of both single word and phrase repetitions, such as a sequence of repeating the word 'ball' while playing with the ball; or repetitions of phrases such as 'want cookie', either immediate or with some intervening talk.</div>
<div><br>
</div>
<div>I know that immediate repetitions are generally not counted according to the criteria established by Brown. I believe that they would be included in the CLAN calculation of MLU unless they are specifically tagged and the command is set to exclude them.</div>
<div><br>
</div>
<div>If you work with MLU or other measures for which it is relevant, how do you treat such repetitions?</div>
<div><br>
</div>
<div>Many thanks in advance,</div>
<div>Diane</div>
