+x+xHi Dave, Thank you for all your help previously! The code works, but in some cases (see screenshot below) for the cupcake stimuli, we have three boys appearing on screen. However, this error is not consistent - it turns up randomly. When I test run the code, it goes okay but when we try it on a participant, sometimes it fails to cover the third boy/girl. We find this error in both cpc_boys.iqx file and cpc_girls.iqx file. ![](../Uploads/Images/3f3ee2e5-fbd0-4eb9-9d48-aa49.png) The link - https://drive.google.com/drive/folders/15fCD0N9K7Wwm9FLY5IExBLd6jrJVMFy_?usp=share_link Figure out in which blocks this happens by looking at the data, then work backwards from there to locate the mistakes in your scripts. The type of mistakes to look out for: For example, in test5a_intro, you're not actually inserting the white rectangle into the test5a_intro trial's stimulus presentation sequence. You're inserting it into an entirely different, irrelevant trial's stimulus presentation sequence, test5_intro. So, nothing will be covered up in test5a_intro. <trial test5a_intro> / ontrialbegin = [ trial.test5a_intro.resetstimulusframes(); // resets the trial's stimulus presentation sequence to its initial state picture.lightblue_circle_right.hposition = 75%; // sets circle of left boy to its normal position picture.lightblue_black_circle_left.hposition = 25%; // sets circle of right boy to its normal position if (picture.activity_group.currentitem == "cupcakes.png" || picture.activity_group.currentitem == "airplanes.png") { // if current activity is either cupcakes or airplanes values.x = replace(75%); trial. test5_intro.insertstimulusframe(shape.whiterect, 1); // cover up the randomly picked boy with white rectangle }; ] /stimulusframes = [1=continue] / validresponse = (continue) </trial>

<trial test1_speech> / stimulusframes = [1=continue, green_speech_right] / validresponse = (continue) </trial>
Hi Dave, thank you for all your help previously. I was trying to remove the randomization and run this code to only cover the left side. But when I run this and click on continue, all the screen goes blank and i can only see the speech bubble. Previously I was seeing the boys and the speech bubble. Could you please correct me with where I might be going wrong
Please take another close look at the code I gave you. Everything in there is important, including the /erase = false settings for the various stimuli.

+xThank you, this is very helpful! Could you please explain what each line of code is doing, so that I can make changes to the other blocks in the experiment accordingly? <trial test1_intro> / ontrialbegin = [ trial.test1_intro.resetstimulusframes(); // resets the trial's stimulus presentation sequence to its initial state picture.blue_circle_left.hposition = 25%; // sets circle of left boy to its normal position picture.green_blue_circle_right.hposition = 75%; // sets circle of right boy to its normal position if (picture.activity_group.currentitem == "cupcakes.png" || picture.activity_group.currentitem == "airplanes.png") { // if current activity is either cupcakes or airplanes values.x = replace(25%, 75%); // pick left or right boy position at random trial.test1_intro.insertstimulusframe(shape.whiterect, 1); // cover up the randomly picked boy with white rectangle if (values.x == 75%) { // if we have to cover up the right boy picture.blue_circle_left.hposition = 75%; // flip the left and right boys' circle positions picture.green_blue_circle_right.hposition = 25%; }; }; ] /stimulusframes = [1=boy_d, boy_e, boy_f, blue_circle_left, green_blue_circle_middle, green_blue_circle_right, continue] / validresponse = (continue) </trial>
All of these things are avaialbe for you to look up in the language reference: https://www.millisecond.com/support/docs/current/html/language/languagereference.htmhttps://www.millisecond.com/support/docs/current/html/language/attributes/ontrialbegin.htmhttps://www.millisecond.com/support/docs/current/html/language/express.htmhttps://www.millisecond.com/support/docs/current/html/language/functions/resetstimulusframes.htmhttps://www.millisecond.com/support/docs/current/html/language/attributes/hposition.htmhttps://www.millisecond.com/support/docs/current/html/language/elements/values.htmhttps://www.millisecond.com/support/docs/current/html/language/properties/currentitem.htmhttps://www.millisecond.com/support/docs/current/html/language/expressions/functions.htmPlease study the programmer's manual: https://www.millisecond.com/support/Inquisit%20Programmer's%20Manual.pdf

+xMy apologies if I am being unclear, but this is my first time seeking help online on the forum so please bear with me. I meant to say that I want to ensure that the two boys that remain (after the white rectangle covers the third one), each have two circles of different colours (just as you mentioned, one green and one blue). I appreciate your help and prompt responses but I am also learning on how to use this software. <trial test1_intro> / ontrialbegin = [ trial.test1_intro.resetstimulusframes(); picture.blue_circle_left.hposition = 25%; picture.green_blue_circle_right.hposition = 75%; if (picture.activity_group.currentitem == "cupcakes.png" || picture.activity_group.currentitem == "airplanes.png") { values.x = replace(25%, 75%); trial.test1_intro.insertstimulusframe(shape.whiterect, 1); if (values.x == 75%) { picture.blue_circle_left.hposition = 75%; picture.green_blue_circle_right.hposition = 25%; }; }; ] /stimulusframes = [1=boy_d, boy_e, boy_f, blue_circle_left, green_blue_circle_middle, green_blue_circle_right, continue] / validresponse = (continue) </trial>

+xThank you! Could you help me out by also making sure that when the cupcakes or airplane stimuli appear, both boys that are presented on the screen have two different colour over their head? Right now it shows one with one coloured circle and the other with two different coulour circles What? I'm sorry, but you're not very clear regarding what you want. What is "[r]ight now it shows one with one coloured circle and the other with two different coulour circles" supposed to mean? That's not even correct; it depends on whether the left boy or the right boy is not shown. And what is "two different colour over their head" supposed to mean? In your script, as it exists, the colors aren't different. Left boy has a single blue circle, middle & right boy have a green & blue circle each.
