My problem is that I think I made a mistake how to use the operator OR and inquisit does not what I want it to. As an example:<br/><br/>&lt;trial greencontrol_easy&gt; <br/>/ontrialbegin = [values.count_control.easy += 1]<br/>/ontrialbegin = [values.congruency = 3]<br/>/ pretrialpause = 250<br/>/ stimulustimes = [0= fixation; 500=greencontrol_easy]<br/>/ correctresponse = ("f")<br/>/ validresponse = ("d", "f", "j")<br/>/ timeout = 2000<br/>/ errormessage = true(x, 400)<br/>/ontrialend = [if (trial.greencontrol_easy.correct) {values.countcorrect_control.easy += 1; values.sumrt_control.easy += trial.greencontrol_easy.latency}]<br/>/ontrialend = [if (trial.greencontrol_easy.response == 0 ) {values.control_oe_easy += 1; values.sumrt_control_oe_easy += trial.greencontrol_easy.latency}]<br/>/ontrialend = [if (trial.greencontrol_easy.response == "j"|| trial.greencontrol_easy.response =="d" ) {values.incorrect_control_easy += 1; values.sumrt_control_incorrect_easy += trial.greencontrol_easy.latency}]<br/>&lt;/trial&gt;<br/><br/>The last bit [if (trial.greencontrol_easy.response == "j"|| trial.greencontrol_easy.response =="d" ) is supposed to count the wrong button presses to the incorrect trials but it doesnt work. Meaning, if the subject presses either "j" or "d", it is a wrong answer, thus it gets added to the values.incorrect_control_easy. BUt it doesnt work. Inquisit runs the entire, no question. But mistakes don't get counted.<br/>What did I do wrong?<br/>If you think you need the entire script, just let me know, I can send it to you as well.<br/><br/>Thanks.<br/>Regards,<br/>Ulrike Nestler<br/>Mon, 14 Dec 2015 08:51:01 GMTUlrike Nestlerhttps://forums.millisecond.com/Topic17975.aspxThe problem isn't the OR operator. The problem is that the response-property *does not* return the "literal" key (e.g. "d" or "k"). It returns the respective numerical keyboard scancode. Thus<br/><br/>if (trial.greencontrol_easy.response == "j" || trial.greencontrol_easy.response == "d")<br/><br/>ought to actually read<br/><br/>if (trial.greencontrol_easy.response == 36 || trial.greencontrol_easy.response == 32)<br/><br/>For details see the "Keyboard Scan Codes" topic in the documentation as well as Tools -&gt; Keyboard Scancodes...<br/>Mon, 14 Dec 2015 08:51:01 GMTDave
