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