I think this is going much better now that the sequence generator is not involved. My remaining issues are: 1) How to add repetitions to the trials so the participants see each photo in each format 6 times without the sequence generator 2) Adding breaks every 96 photos (trial: "instructions2") - would I do this by having something such as: trials 1-96 = noreplace(AAT_1, AAT_2, AAT_3, AAT_4), 97 = instructions2; 98-194 = noreplace(AAT_1, AAT_2, AAT_3, AAT_4) 3) Is this something I delete from the block now that I don't have the sequence generator? "on blockbegin = [values.index = 0]" Here's what I have so far: <block practice_AAT> / trials = [1-2 = instructions; 3-12 = noreplace(practicetrial_A, practicetrial_B)] </block> <block assessment1untrained_AAT> / onblockbegin = [values.index = 0] / trials = [1 = instructions; 2-33 = noreplace(AAT_1, AAT_2, AAT_3, AAT_4)] </block> <block assessment2trained_AAT> / onblockbegin = [values.index = 0] / trials = [1 = instructions2; 2-33 = noreplace(AAT_5, AAT_6, AAT_7, AAT_8)] </block> <expt> / subjects = (1 of 1) / groupassignment = groupnumber / onexptbegin = [ values.expcondition = 1; values.format1 = "PORTRAIT"; values.format2 = "LANDSCAPE"; values.startheight_A = parameters.Startheight_ratioAvalues.Maxheight_px; values.startheight_B = parameters.Startheight_ratioB values.Maxheight_px; ] / blocks = [ 1 = practice_AAT; 2 = assessment1untrained_AAT; 3 = assessment2trained_AAT; ] / postinstructions = (End) / onexptend = [values.completed = 1] </expt> > 1) How to add repetitions to the trials so the participants see each photo in each format 6 times That is no different than running the requisite amount of trials.

"on blockbegin = [values.index = 0]" You can leave that in, it does not make any difference. Hi Dave, Thank you again for your help. I deleted "values.index = 0 in the block" because the script wouldn't run with it and now it will run. To show each image 6 times, I made 6 identical blocks but now realize they will go in order of the blocks and not randomize across blocks. The photos from all categories below should all be shown 6 times but in random order. And also, not sure how to make sure the break is in there every 96 photos. It feels like instead of what I have tried, I need to be making one large block with all 192 photos and somehow specifying to randomize but show all participants each photos 6 times - could you please let me know the command for this and if this makes sense to you? Then I will repeat the procedure for the second half of the assessment, which is identical but with different photos and 288 trials. Thank you again! main category 1 (threat, untrained) landscape (trial is AAT_1): indices 1-8 main category 1 (threat, untrained) portrait (trial is AAT_2): indices 9-16 main category 2 (neutral, untrained) landscape (trial is AAT_3): indices 17-24 main category 2 (neutral, untrained) portrait (trial is AAT_4): indices 25-32 <block practice_AAT> / trials = [1-2 = instructions; 3-12 = noreplace(practicetrial_A, practicetrial_B)] </block> <block assessment1untrained_AAT_1> / trials = [1 = 33 = noreplace(AAT_1, AAT_2, AAT_3, AAT_4)] </block> <block assessment1untrained_AAT_2> / trials = [1 = instructions; 2-33 = noreplace(AAT_1, AAT_2, AAT_3, AAT_4)] </block> <block assessment1untrained_AAT_3> / trials = [1 = instructions; 2-33 = noreplace(AAT_1, AAT_2, AAT_3, AAT_4)] </block> <block assessment1untrained_AAT_4> / trials = [1 = instructions; 2-33 = noreplace(AAT_1, AAT_2, AAT_3, AAT_4)] </block> <block assessment1untrained_AAT_5> / trials = [1 = instructions; 2-33 = noreplace(AAT_1, AAT_2, AAT_3, AAT_4)] </block> <block assessment1untrained_AAT_6> / trials = [1 = instructions; 2-33 = noreplace(AAT_1, AAT_2, AAT_3, AAT_4)] </block> / blocks = [ 1 = practice_AAT; 2 = assessment1untrained_AAT_1; 3 = assessment1untrained_AAT_2; 4 = assessment1untrained_AAT_3; 5 = assessment1untrained_AAT_4; 6 = assessment1untrained_AAT_5; 7 = assessment1untrained_AAT_6; The way your images are sampled has nothing to do with the order of the blocks. The code you posted is not relevant to that. You'll want to sample your image items -- i.e. the various indices / item numbers you indicated -- without replacement. If <trial AAT_1> samples indices 1 to 8 from a <list> without replacement, and you run <trial AAT_1> a total of 48 times, then you have 6 repetitions of those 8 images. The same is true for the other categories / indices. As for running all 192 trials in a single block with a break in-between, see my previous response to your question #2: / trials = [1-96, 98-193 = noreplace(AAT_1, AAT_2, AAT_3, AAT_4); 97 = instructions2] Thank you again! I have changed the code by making just two blocks, one for the first half of assessment which is 192 trials (4 groups of 8 images, each image shown 6 times), and one for second half which is 288 trials (4 groups of 12 images, each shown 6 times). My remaining question about this aspect of the experiment is how can I guarantee that each of the images is shown 6 times each within the randomization scheme? Or can I be assured of this based on the code I do have?

Group: Administrators Posts: 13K, Visits: 107K	+x inquisituser22 - 7/9/2019 +x Dave - 7/8/2019 +x Dave - 7/8/2019 Thanks for the file. The code as-is does not make use of the generated sequence, so -- right now -- it doesn't really make sense to run the sequence generation block at all. The freezing / blank screen occurs because, as I suspected, the generator runs into an unrecoverable state or endless loop because it cannot create a suitable sequence. Some of that is due to misconfiguration of the various <values>. /totaltrialcount ought to specify the desired length of the sequence, that is the total amount of trials you want to create a sequence for. /count1 to /count8 ought to reflect the desired number of trials for each respective category (it's 10 per category in the original); neither /totaltrialcount nor the /count1 to /count8 values may all be set to zero as in your modification of the sequence generator. Also note that, if you do change the values for /count1 to /count8, you need to modify the reset logic in <trial selectnumber> accordingly, otherwise they'll end up being reset to the default 10: /ontrialend = [if (values.reset == true) { values.sequence = ""; values.index = 0; values.count_comparecat = 0; values.count_compareformat = 0; values.runcount_1 = 0; values.runcount_2 = 0; values.runcount_3 = 0; values.runcount_4 = 0; values.runcount_A = 0; values.runcount_B = 0; values.count1 = 10; values.count2 = 10; values.count3 = 10; values.count4 = 10; values.count5 = 10; values.count6 = 10; values.count7 = 10; values.count8 = 10; list.stimcats.reset() }] As I've said before, I don't necessarily think relying on the sequence generator is recommendable in your case, especially since you effectively seem to want two separate / distinct sequences (one for the trained, another for the untrained part) with different parameters. I don't see a straightforward way to extend the generator to create such a thing in one go. I've coded up a stand-alone version the sequence generator that displays the generated sequence and its various parameters on-screen as it occurs in real time. It will alert to you resets as well as successful sequence generation and display the results on the monitor for review. This should make it easier to understand its mechanics, toy around with different settings and modifications and then examine their effects on sequence generation. Dave, Thank you so very much for all of this help!! Since you don't recommend the sequence generator for my particular experiment, please let me know if this is the way you would recommend I proceed. I could put the threat and neutral images into 2 categories, then change "values.targetformat = "l";" to generate whether its landscape or portrait, not using the sequence generator for this? I would need 50% to be landscape and 50% to be portrait however, and am not randomizing across participants but within the trial 50/50. So not sure how to modify that. And since you said I should change the values, since my experiment is 6 repetitions and 480 trials overall, would "totaltrialcount" be 6 here, or 480? also not sure if I would change any of the other values. Thank you so much for your patience with me as I learn this! My experiment is: a. First half of assessment:8 threat photos in landscape - 6 times. 48 photos. 8 threat photos in portrait (same ones) - 6 times. 48 photos. 8 Neutral photos in landscape - 6 times. 48 photos. 8 Neutral photos in portrait (same ones) - 6 times. 48 photos. There is break every 96 photos b. Second half of assessment: 12 threat photos in landscape - 6 times. 72 photos. 12 threat photos in portrait (same ones) - 6 times. 72 photos. 12 Neutral photos in landscape - 6 times. 72 photos. 12 Neutral photos in portrait (same ones) - 6 times. 72 photos. There is break every 96 photos. ******************************************************************************************************************************** <values > / totaltrialcount = 0 / nextstimulus = 0 / selectstimulus = 0 / targetcategory = 0 / targetformat = "" / repeat = 0 / selectpracticepicture = 0 / starttime = 0 / endtime = 0 / expcondition = 0 / format1 = 0 / format2 = 0 / startheight_A = 0 / startheight_B = 0 / Maxheight_px = display.canvasheight / joystick_y = 0 **** <trial AAT_1untrained> / ontrialbegin = [ values.selectstimulus = list.category1.nextvalue; values.targetcategory = 1; values.targetformat = "l"; picture.targetstimulus.height = values.startheight_A; values.starttime = script.elapsedtime; values.endtime = 0; values.completeRT = 0; values.changedirection = 0; values.finalresponse=""; / completeRT = 0 / changedirection = 0 / joystick_change = 0 / trialcode = 0 / RT = 0 / correct = 0 / stimulus = 0 / initialresponse = "" / finalresponse = "" / completed = 0 </values> If you don't use the sequence generator, you can ignore values.totaltrialcount. Otherwise it should be set to the value reflecting the length of the sequence you want to generate, i.e. the number of trials the sequence is supposed to encode. You'll want to set up separate <trial> elements for your various conditions, i.e. one <trial> for threat/landscape, one <trial> for threat/portrait, one <trial> for neutral/landscape, one <trial> for neutral/portrait, for the 1st half (a) of the assessment. Sample them in the desired proportion as needed via a <block>'s /trials. Do the same for the 2nd half (b), run the blocks in the desired order via your <expt>.

The code as-is does not make use of the generated sequence, so -- right now -- it doesn't really make sense to run the sequence generation block at all. The freezing / blank screen occurs because, as I suspected, the generator runs into an unrecoverable state or endless loop because it cannot create a suitable sequence. Some of that is due to misconfiguration of the various <values>. /totaltrialcount ought to specify the desired length of the sequence, that is the total amount of trials you want to create a sequence for. /count1 to /count8 ought to reflect the desired number of trials for each respective category (it's 10 per category in the original); neither /totaltrialcount nor the /count1 to /count8 values may all be set to zero as in your modification of the sequence generator. Also note that, if you do change the values for /count1 to /count8, you need to modify the reset logic in <trial selectnumber> accordingly, otherwise they'll end up being reset to the default 10: /ontrialend = [if (values.reset == true) { values.sequence = ""; values.index = 0; values.count_comparecat = 0; values.count_compareformat = 0; values.runcount_1 = 0; values.runcount_2 = 0; values.runcount_3 = 0; values.runcount_4 = 0; values.runcount_A = 0; values.runcount_B = 0; values.count1 = 10; values.count2 = 10; values.count3 = 10; values.count4 = 10; values.count5 = 10; values.count6 = 10; values.count7 = 10; values.count8 = 10; list.stimcats.reset() }] As I've said before, I don't necessarily think relying on the sequence generator is recommendable in your case, especially since you effectively seem to want two separate / distinct sequences (one for the trained, another for the untrained part) with different parameters. I don't see a straightforward way to extend the generator to create such a thing in one go. I've coded up a stand-alone version the sequence generator that displays the generated sequence and its various parameters on-screen as it occurs in real time. It will alert to you resets as well as successful sequence generation and display the results on the monitor for review. This should make it easier to understand its mechanics, toy around with different settings and modifications and then examine their effects on sequence generation. Dave, Thank you so very much for all of this help!! Since you don't recommend the sequence generator for my particular experiment, please let me know if this is the way you would recommend I proceed. I could put the threat and neutral images into 2 categories, then change "values.targetformat = "l";" to generate whether its landscape or portrait, not using the sequence generator for this? I would need 50% to be landscape and 50% to be portrait however, and am not randomizing across participants but within the trial 50/50. So not sure how to modify that. And since you said I should change the values, since my experiment is 6 repetitions and 480 trials overall, would "totaltrialcount" be 6 here, or 480? also not sure if I would change any of the other values.

I have been attempting to address this from your comments as well as prior threads' comments, but my script doesn't seem to be loading properly as I have to do control B to get past the first (blank) page. If you are able to provide me with any feedback as to where I went wrong, that would be greatly appreciated. I've reduced the number of trials in my experiment's methods since previously posting and here is what I am trying to achieve now. I have a feeling it relates to "values.index" but I have had trouble following how to modify it correctly. Thank you so very much in advance. 2 Parts of my experiment to be run sequentially: Part 1: 2 categories of ("untrained") images x 8 images x 2 formats (landscape/portrait - same for all participants, not randomizing who sees which format) x 6 repetitions = 192 trials Part 2: 2 categories of ("trained") images x 12 images x 2 formats x 6 repetitions = 288 trials There will be instructions telling participants to take a break every 96 trials.

Of note, these are just placeholders for the images as we are currently working on preparing them. In an ideal world, we were going to use the sequence generator for semi-randomization, but if it becomes too complicated I am okay with eliminating it and having simple randomization through just the main script instead.
