Hi Michael and thank you for your reply.<br>The problem is that when I go back to the labelX the time that the subject "passes" on the slide1 starts again from 0. But when the subject presses the key (before the reward is available), I would be able to stay on the same slide, so the timer will keep counting the time. <br>I will explain myself better: <br><br>imagine that the random number is 2.34seconds. Now the subject press the key after 1 seconds. I would like to be able to have the subject to continue to see the same slide. So the subject waits another 1.5 seconds (and the total is now 2.5 seconds) before pressing the button. But now, when he/her presses it, the software goes to the next slide.<br><br>In you example the subject will always starts from 0. So using the same random number as before, if he/her presses the key after 1 seconds, he has to wait at least 2.34 seconds before pressing the key and getting the reward (whereas in the previous example, after the first pressing, he/her has to wait just a minimum of 1.34 seconds).<br><br> <br><br><br>On Friday, 22 March 2013 11:44:22 UTC, Michiel Sovijärvi-Spapé wrote:<blockquote class="gmail_quote" style="margin: 0;margin-left: 0.8ex;border-left: 1px #ccc solid;padding-left: 1ex;"><div link="blue" vlink="purple" lang="EN-US"><div><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d">Hi,</span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d">It’s not really that strange – I find that many people, but cognitive psychologists in particular, seem unaware of just how very small the world of their favourite paradigm can be </span><span style="font-size:11.0pt;font-family:Wingdings;color:#1f497d">J</span><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d"> In fact, I have not heard of this procedure and I suppose this is because it is more popular with those who’re more interested in the conditioning side of things, but I could be wrong there. </span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d">In any case, what’s wrong with </span></p><p><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d"><span>1.<span style="font:7.0pt "Times New Roman""> </span></span></span><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d">Inline: Accuracy = -1</span></p><p><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d"><span>2.<span style="font:7.0pt "Times New Roman""> </span></span></span><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d">LabelX</span></p><p><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d"><span>3.<span style="font:7.0pt "Times New Roman""> </span></span></span><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d">Slide, set .Duration to -1. </span></p><p><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d"><span>4.<span style="font:7.0pt "Times New Roman""> </span></span></span><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d">If Slide.RT < T then </span></p><p style="margin-left:72.0pt"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d">Accuracy = 0</span></p><p style="margin-left:72.0pt"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d">Goto LabelX</span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d">Etc?</span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d">Sorry, it’s Friday, difficult to think very straight, but to be honest, I cannot see what’s wrong with just going back to the moment just before the slide is presented. </span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d">Best,</span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d">Michiel</span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d"> </span></p><div style="border:none;border-top:solid #b5c4df 1.0pt;padding:3.0pt 0cm 0cm 0cm"><p class="MsoNormal"><b><span style="font-size:10.0pt;font-family:"Tahoma","sans-serif"">From:</span></b><span style="font-size:10.0pt;font-family:"Tahoma","sans-serif""> <a href="javascript:" target="_blank" gdf-obfuscated-mailto="mCQeXUTb6Y0J">e-p...@googlegroups.com</a> [mailto:<a href="javascript:" target="_blank" gdf-obfuscated-mailto="mCQeXUTb6Y0J">e-p...@googlegroups.<wbr>com</a>] <b>On Behalf Of </b>Valerio Biscione<br><b>Sent:</b> 22.

At the beginning of the slide a random number is generated. This random number indicates the number of milliseconds that the subjects has to wait to receive a reward. Let's call this random number T. The subject can press the key anytime he/she wants, but only if he presses the time AFTER the time T he will receive a reward and the software can go to the next slide. If he presses the key before T he receive a punishment, but can still try to "win" the reward in the slide.<br><br>I already solved the problem to record all the RTtime that the subject press the key during the slide. The problem is to make the software to go further ONLY if the key is pressed after T. T is recorded in a variable, but won't be a problem to use an attribute.<br>Do you have any idea?<br>Kind Regards<br>Valerio </p><p class="MsoNormal">-- <br>You received this message because you are subscribed to the Google Groups "E-Prime" group.<br>To unsubscribe from this group and stop receiving emails from it, send an email to <a href="javascript:" target="_blank" gdf-obfuscated-mailto="mCQeXUTb6Y0J">e-prime+u...@<wbr>googlegroups.com</a>.<br>To post to this group, send email to <a href="javascript:" target="_blank" gdf-obfuscated-mailto="mCQeXUTb6Y0J">e-p...@googlegroups.com</a>.<br>To view this discussion on the web visit <a href="https://groups.google.com/d/msg/e-prime/-/xIBEh-dbA3oJ" target="_blank">https://groups.google.com/d/<wbr>msg/e-prime/-/xIBEh-dbA3oJ</a>.<br>For more options, visit <a href="https://groups.google.com/groups/opt_out" target="_blank">https://groups.google.com/<wbr>groups/opt_out</a>.<br> <br> </p></div></div></blockquote>
