Interesting. We plan to use the DirectIn Keyboard from Empirisoft at both sites. http://www.empirisoft.com/directinkb.aspx<br><br>On Monday, December 17, 2012 1:45:32 PM UTC-5, Roland Dardennes wrote:<blockquote class="gmail_quote" style="margin: 0;margin-left: 0.8ex;border-left: 1px #ccc solid;padding-left: 1ex;">Will you use response boxes or computer keyboards ?

<br>for each of the two colleges where she included volunteers. It
<br>happened that she had a systematic difference of 40 ms between the
<br>sites' means ... But I have non idea how to check this between two
<br>given keyboards. It may not be a problem if you are substracting RT in
<br>one condition from RT in another condition, but it may be if you are
<br>working with absolute RT.

<br>Good luck
