Perhaps you are working with some old version of the manual or perhaps some locally-prepared guideliness. Best to get new versions from the web.</div><div class=""> </div><div class=""> There are other ways, besides t-units, to look at syntactic complexity. MLU is not bad for children or aphasics, but I don’t yet know about AD. CLAN also includes the IPSyn and DSS programs, but again they are really targeted to studies of language development. Recently we introduced the CPIDR propositional density measure which played a big role in the Nun’s Study for AD. Perhaps that would be useful in your case. All of these measures require you to have first run MOR on your transcript to create a %mor line. </div><div class=""><br class=""></div><div class="">—Brian MacWhinney</div><div class=""><br class=""></div><div class=""><div class=""><div><blockquote type="cite" class=""><div class="">On Jun 12, 2015, at 10:13 AM, Kimberly Mueller <<a href="mailto:digglekim@gmail.com" class="">digglekim@gmail.com</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><div dir="ltr" class="">Dear All,<br class=""><br class="">Kimberly Mueller here from UW Madison, using CHAT/CLAN (thank you!!!) to transcribe 5-10 minute language samples from adults ages 40 - 80 who are at risk for developing Alzheimer's Disease.<br class=""><br class="">Would anyone (and/or everyone!) please provide guidance on measures you recommend to capture syntactic complexity?

example, in speech, we often start sentences with “because.” “Because”
is typically at the beginning of a dependent clause in written
communication; however, we use this to start sentences when speaking and

starting the sentence in a spoken utterance. </i></font></p><br class=""></div><div class=""><br class="webkit-block-placeholder"></div>
