  • Hi, What kind of puzzle do you have in mind? Basically what you can do is create a custom form that consists of labels and text inputs, but setting this up will be a pain. You could draw a grid on a canvas with small text in some fields, but that …
  • http://forum.cogsci.nl/uploads/109/C6P3QOOEBFYA.osexp Hi, Sorry for the long delay. I cannot figure out how I can repeat the whole sequence (that is: the seven different sequences) in a random order A loop item has a field called repeats, set this …
  • Hi, That is a weird error, I don't know how to solve it, honestly. It seems to be related to the mousetrap plugin somehow. To be not entirely useless, I modified your script a little to make it a little clearer. Sorry, Eduard http://forum.cogsc…
  • Hi Mollie, The attached file is updated to make sure no stimuli are repeated. http://forum.cogsci.nl/uploads/249/68UJDQ7UZTKF.osexp
  • you can add an inline_script to the add of your sequence (after the response item), that increments the number of responses, and the number of correct responses. In the end of the experiment, you can then compute accuracy by dividing correct trials …
  • Hi, Can you start the video, and after that add a loop/sequence construct that repeatedly loops a keyboard response item and a logger. Also, don't forget to define a break criterion that the loop will be terminated, once the video is over. Hope t…
  • Hi Nicole, I can only check whether the b-item should be displayed after the first item was executed and the participants chose their answer. In this case, you are right. You will need to first execute one form without the b-item, once the partici…
  • Hi Yanwei, You can use the variable "var.subject_nr" in combination with the modulo (%) operator. So for every block loop, put in the run if field something like "(1+var.subject_nr%4)=1" (or 2, 3, 4). Does that make sense? Eduard
  • Hi Mollie, I finally got to implement something that might be useful to you. The exciting things happen in the inline script "counterbalancing", in which the trial sequence is implemented. In the inline_script "selectTrialItem", the item per trial …
  • Hi Nicole, I think the easiest solution is to abandon the sequence structure and have all the elements within a single inline_script (that is within a single trial, across trials you can still use an inline_script) Like you already do, prepare all …
  • Sorry Molly, I am having a look at your script right now, but I have a hard time understanding what is supposed to happen exactly. Could you maybe summarize again super briefly your final goal and your current approach to achieving (incl. which vari…
  • Hi Dror, You can make the experimental file read-only with the regular commands of your Operating system (e.g. https://www.wikihow.com/Make-a-File-Read-Only) Not sure whether the files can then still be opened with Opensesame, though. Eduard
  • Hi, You can use Python to set up the sequences before you enter them, like this (simplified example): import random # example for 4 videos, but same logic applies for 18 videos videos = ['1.flv','2.flv','3.flv','4.flv'] random.shuffle(videos) # cha…
  • Hi Omer, I wouldn't expect any problems with 3 keyboards, but still it would make sense to extensively test the procedure. Implementing point 3 shouldn't be very hard. Put an inline_script with the line: `var.start_time = clock.time()`before the …
  • To add to Lucie's response, if you use a regular keyboard response item, the line would be: [response]=None Eduard
  • HI, That is also a little hard to understand without more information. What code do you use? What is your experimental structure? Maybe you can upload your experiment, or at least upload some screenshots. Without more information it will be diffic…
  • No, It is not about Expyriment. Corinne, the link that I send you is quite clear on that and even gives an example how to add underlines to text. You should try more to figure out things by yourself based on manuals and such. On the long run, you wi…

  • Well, the error message means that the file false.jpg has not been found in the file pool, but I can see it there, so it is a little confusing why the error occurred. Have you added the variable to the file pool? So drag and drop the entire folder …
  • Hi Mollie, Can you share your experiment here. I think it might be quicker if I directly edit there. Another thought that I have (maybe nonsense), but if your main concern is to control the side at which the target appears, it would make more sense…
  • Hi, It seems the experiment has been written for an old version of Opensesame. Once you open the script you can see that the text display item are not supported anymore. You can replace them with form_text_display items. And add the text informatio…

  • Hi Corinne, You can use HTML tags to edit text. See here: https://osdoc.cogsci.nl/3.2/manual/stimuli/text/#html-formatting Good luck, Eduard

  • Hi Jasper, Not sure why (maybe intentional, maybe a bug), but the size keyword doesn't do anything if you use a gaussian envelope on your grating. To manipulate the size, you have to instead change the "stdev" keyword. For Gaussian Gabors, size is …
  • Hi, How consistent is that error? Does it always occur, or only sometimes? And always with the same error? Does the problem occur also on different computers? eduard
  • Hi So So, What is your approach? What have you tried? there are several ways to do that. It depends on your structure what would be the "best" way. Eduard
  • Hi, I don't like this solution as it is rather hacky and probably produces messy logfiles, but see for yourself whether it helps you. Basically, I make the last word appear in a special sketchpad linked to a special mousetrap item, lasting only fo…
  • Hi, This sounds like the maximum x and y position are hardcoded to the window size. If you go to the settings of the experiment and change the width and height of the experiment to the one of your screen, the slider should work in its completeness…
  • Hi, Both are perfectly fine options. Randomization is easier if everything is in the same block loop, but having 3 different loop also works. If you have everything in one loop, you have to make sure that the right things are presented at the right…
  • Hi Daniel, Unfortunately, I don't have much knowledge about parallel ports and such. However, to increase the changes that you get help here on the forum it might be useful, if you could provide more information on how exactly does not work. Is the…
  • Hi, You can try to browse the forum for examples, or some other online resources (e.g. https://osf.io/d2ecb/). However, I don't think the problem is very hard. You should be able to implement it yourself. You just need a sequence with sampler (pl…
  • Hi Johannes, Yes, that is very possible (I recommend the drag and drop option). I could try to make you a little script that brings you towards your solution, but I think the mousetrap plugin could make your life much easier, and I haven't worked …
