For the % of misses on no-signal trials you'll want to look at expressions.miss. In any case, you'll want to thoroughly review Verbruggen et al. (2008) as cited both in the script as well as on the download page, which covers the variables captured in great detail.</p> <p>Regards,</p> <p>~Dave</p>Thu, 21 Jun 2012 04:06:56 GMTDavehttps://forums.millisecond.com/Topic8267.aspx<p>Hi!</p> <p>I did not understand how to use the output file for this task!<br />Which column I have to look at in order to know how many errors the subject has done during the task?</p> <p>thank you much!</p> <p>Guglielmo</p>Thu, 21 Jun 2012 02:56:28 GMTGuglielmo
