Group: Forum Members Posts: 3, Visits: 15	Hi everyone. Apologies in advance for posting this if this is a duplicate. I am running an experiment and i am using inquisit 5. My issue is that i need a pause/delay before each stimuli. I have created a list of text items and between each text item i would like a 250ms delay. I searched through documentation and found this https://www.millisecond.com/support/docs/v5/html/viewer.htm#howto/howtocontroltiming.htm. I have tried using response as well as pretrialpause but neither gave the effect i was looking for. I believe numframes is what i need but im not exactly sure how to use it. I have an excerpt of the code i am using below and any help would be appreciated. Thanks in advance <text distractorLike> / items = distractorLike </text> <item distractorLike> / 1 = "Mexican food" / 2 = "Victory" / 3 = "Wheat" / 4 = "Dairy Queen" / 5 = "Peanut butter" / 6 = "Watching TV" / 7 = "Roses" / 8 = "Eating pizza" / 9 = "Candy" /10 = "Welfare reform" </item> <text distractorDislike> / items = distractorDislike </text> <item distractorDislike> / 1 = "Doing homework" / 2 = "Large lecture classes" / 3 = "Lice" / 4 = "Tuition increases" / 5 = "Blisters" / 6 = "Election reform" / 7 = "Spiders" / 8 = "Jazz" / 9 = "Capital punishment" /10 = "Pass/fail grading" </item> <trial distractorlike> / validresponse = ("z", "/") / correctresponse = ("/") / stimulusframes = [1=distractorLike] </trial> <trial distractordislike> / validresponse = ("z", "/") / correctresponse = ("z") / stimulusframes = [1=distractorDislike] </trial> <block practice> / trials = [1-20 = noreplace(distractorLike, distractorDislike)] / bgstim = (likereminder, dislikereminder) / preinstructions = (practicepage) </block>

What the code as posted will do is present a blank screen for 250ms (per /pretrialpause), display a stimulus, the stimulus will remain on-screen until you give a response. Then the trial terminates, and the next trial starts with a 250ms blank screen (per /pretrialpause). In other words, I'm not sure what "I have created a list of text items and between each text item i would like a 250ms delay" is supposed to mean -- it can be interpreted in a number of very different ways. So: Could you clarify what effect you're aiming for precisely? Edited 8 Years Ago by Dave

Though would there be a way to put a "Get Ready" as the text during a pause? Sorry for the confusion, so the delay would be a small window allowing participants to pause before they see the next stimuli. Otherwise they could click through the entire stimuli list without actually making any judgments. My ideal setup would be to do the following: Instructions Get Ready (Blank Screen) Stimuli Get Ready (Blank Screen) Stimuli ....

You would use the trial's /stimulustimes instead, i.e. <trial distractorlike> / validresponse = ("z", "/") / correctresponse = ("/") / stimulustimes = [0=getready; 250=clearscreen, distractorlike] </trial> where getready is a simple <text> element <text getready> / items = ("Get Ready") </text>
