Dear Brian,<br>I'm thinking types. I've got some data for one-year olds: their vocabularies look pretty idiosyncratic to me, but I'd like something to compare to...<br><br>Thanks for the lead to Jean's work: I didn't know about it!<br>
Much appreciated,<br>Elena<br><br><div class="gmail_quote">On Mon, Nov 19, 2012 at 4:57 PM, Brian MacWhinney <span dir="ltr"><<a href="mailto:macw@cmu.edu" target="_blank">macw@cmu.edu</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
<div style="word-wrap:break-word">Dear Elena,<div> Jean Berko-Gleason and Richard Ely worked things related to this issue. The children they studied were a bit older and the emphasis there was on different recording situations, but they found that there was a great deal of non-overlap across situations and also across children. Of course, this type of glass can be half full and half empty. Common function words are going to overlap; it is for the less frequent words that we find the strong non-overlap. Jean's corpora are in CHILDES and the papers are mostly from the late 1990s. Jean can provide more info. </div>
<div> By the way, when you talk about "percentage of words", I wonder if you mean types or tokens? I assume you mean types.</div><div><br></div><div>-- Brian MacWhinney</div><div><br><div><div><div class="h5">

I'm trying to find some sort of quantification of how idiosyncratic children aged 2-3 years are in terms of vocabulary. Has anyone, for example, attempted something as foolhardy as calculating the average percentage of words shared by all/most/some preschoolers?? <br>
