It works fine now =)<br/>Thu, 18 Jun 2015 01:20:17 GMTjuly1810https://forums.millisecond.com/Topic16523.aspx#1: It looks like you also present &lt;port&gt; stimuli via the /stimulustimes attribute. You *must* make sure to also reset all those raised bits to zero after a short amount of time in /stimulustimes. Otherwise the signal will *remain raised* and mask the &lt;port&gt; signals you are trying to send via /responsemessage. See e.g. this example:<br/><br/><a href="https://www.millisecond.com/forums/FindPost15055.aspx">https://www.millisecond.com/forums/FindPost15055.aspx</a><br/><br/>#2: You should set a sufficient minimum duration in your /responsemessage attributes. Otherwise the signal may not be raised long enough for your external equipment to detect it.<br/><br/>/responsemessage = (values.correctresponse, signal_response_correct, <strong>0</strong>)<br/><br/>#3: Also, the syntax in your /responsemessage attributes is wrong. You cannot use variables in it:<br/><br/>/responsemessage = (<span style="text-decoration: underline;">values.correctresponse</span>, signal_response_correct, 0)<br/><br/>The right thing to do is to use the /correct- and /errormessage attributes instead. I.e.<br/><br/>&lt;trial block1_congruent&gt;<br/>...<br/><strike>/responsemessage = (values.correctresponse, signal_response_correct, 0)<br/>/responsemessage = (values.errorresponse, signal_response_error, 0)</strike><br/>/ correctmessage = (signal_response_correct, 100)<br/>/ errormessage = (signal_response_error, 100)<br/>/responseinterrupt = trial<br/>/trialduration = values.iti_congruent<br/><br/>...<br/>&lt;/trial&gt;<br/>Wed, 17 Jun 2015 04:28:37 GMTDave
