Hi, Ali,<div><br></div><div>Your question is apt and timely, but difficult to answer. I assume that 'sees' and 'reads' is just a slip (?read 'writes' for 'reads'?). Incidentally, I don't know offhand of any work on the following issue, but I assume (from the wording of yr question, I assume that you do too, actually) the crucial aspects of the answer are the *exposure* (hears, reads) rather than the use (writes, speaks), the latter being more practice than exposure (ok, it's also secondarily exposure, too). As many researchers have pointed out over the last half-century, especially, even the same person is exposed at different times to very different genres of the same language, and we know that changing genres may greatly affect the distribution of word frequencies. </div>
<div><br></div><div>That is, you can't really get a reliable picture of the *daily* exposure, even of an individual, and much less of a group, since unpredictable changes in (word) fashion, general interest stories on the news, etc., can affect frequencies (just one obvious example: the *total* frequency of 'HIV' plus its expanded version before about 1980 was *0*, while now it is fairly common). Likewise, there are well-known differences between aural and visual (spoken and read) reception, namely that, roughly, the spoken lexicon is smaller than the written one, with the more (respectively, less) common words even more (resp., less) common in speech than in writing. </div>
<div><br></div><div>I don't really have at hand any good references to answer your question, though I'm sure that others will answer you with concrete studies, which *do* exist. (eg, the answer you received while I was writing this).</div>
<div><br></div><div>One fairly well-established fact: of the very most common words (say, the first couple dozen or so), their relative distribution stays pretty constant over different genres (but note: even here, if you examine, say, headlines and billboards and the like, these 'function words' may drop drastically in frequency).</div>

Hi Guys,<br><br>I have a quick question. I'm wondering if anyone can point me towards studies which have looked at any one or combination of the average number of words that a person:<br><div style="margin-left:40px">
<ul><li>hears</li><li>sees</li><li>reads</li><li>speaks</li></ul></div>on a daily basis.<br><br>I'm generally interested in the overall word daily <i>exposure</i> (I don't care if the words have been processed, just picked up by the relevant auditory / visual cortices ), though if there are studies that focus on processed words that's fine.<br>
<br>The main "sources" I've found are via: <a href="http://www.boston.com/news/globe/ideas/articles/2006/09/24/sex_on_the_brain/" target="_blank">http://www.boston.com/news/globe/ideas/articles/2006/09/24/sex_on_the_brain/</a><br>
which focus on words spoken. And as that article notes (and I've
confirmed for the studies I've been able to track down), almost none of
those "sources" actually cite or indicate how the word count was
derived.<br><br>This question is motivated by the BNC's 100 million word corpus. How many months / years of word exposure is that for your "average" North American(?) adult?<br><br>Thank you kindly,<br>Ali Hashemi<br clear="all">
