Hello again, <br>
<br>
I am using the CHIP utility for a research project. I am interested in <br>
looking at how much mothers imitate and expand upon child utterances and <br>
whether that facilitates language development.<br>
<br>
I have a few questions about some of the summary measures included in CHIP. <br>
I plan to use %_Overlap and %_EXPAN in my analysis, but I am not sure I <br>
understand Avg_Dist, Rep_Index, and %_IMITAT. These are the descriptions <br>
included in the manual:<br>
<br>
“$DIST: the distance the response utterance is from the source”<br>
<br>
“Avg_Dist: The sum of the DIST values divided by the total number of <br>
overlapping utterances.” <br>
<br>
“Rep_Index: Average proportion of repetition between the source and <br>
response utterance across all the overlapping responses in the data.” <br>
<br>
“%_IMITAT: ?? The numerator is the number of imitations and the denominator <br>
is ???”<br>
<br>
My questions are: <br>
<br>
<br>
1. How is distance measured? Is this how many utterances there are <br>
between source and response?<br>
2. Is the Rep_Index how closely the source and response match (e.g. 3 <br>
out of 4 words match)?<br>
3. Does %_IMITAT measure percent of responses that exactly imitate the <br>
source? What is the denominator?<br>
<br>
Any further explanation you could provide on these measures would be very <br>
helpful. Thank you again for all of your help and for this wonderful <br>
program!<br>

Dear Jenna,<br>
Page 68 of the manual explains that the nature of the source and the target varies depending on whether the report is in the %chi, %adu, %csr, or %asr tier. On page 70, the manual explains that distance refers to distance in terms of utterances. Yes, the Rep_Index reflects the number of matching words. Regarding %_IMITAT, you might notice that I was a bit unclear about this index when I wrote the documentation in the manual and so I put question marks. I assume the denominator is the number of utterances. If this is important to you, we could set up a large test corpus to see exactly what this is doing. There is a chip.cha file in the /examples folder that we could extend to check on this.<br>
