Hi Eva, Set the duration of the sketchpad to 0 and it should work. Eduard

Hi, You can add somewhere a little script that does something along the line: if current_response == None: # if there was no response on that trial response.add() Do get the gist? Eduard
-
Hi, What if you add a video playback item at the end of the stimuli_sequence? Then, it would be shown after all of the images (there are only 4 in your script?) have been shown. Does this make sense? Eduard

Hi, Sorry for not having gotten back to you before you solved it yourself (credits to yourself!). Sounds like a nice paradigm. Once it is finished, you can upload it to https://osf.io/d2ecb/. This is soft of a repository for Opensesame experiments.…

Hi Tyler, That is very possible. If you use Pygaze to design your entire experiment, you probably start with an example experiment from their website (ww.pygaze.org). Then, you add step-by-step the gaze-contigent-functionality (see for example th…

Hi, In the loop_table of your block loop, you can have a variable called block_type that can have the values noise, no_noise. Next, in the loop table of your trial_loop you add a variable trial_type with the values noise or no_noise. Finally, in th…

Hi, Yes, that is possible. Eduard

Hi Kara, I'm not sure, but I would say as long as those files are only read, it should work. Editing, that is writing to, a file would cause problems, but reading should work (I guess). eduard

Hi, Choose the code that works. The script is simple enough that computation time and efficiency don't matter. And if the code does what you want, your settled. #variable fixation durationvar.fix_bottom = 250var.fix_top = 750f = range(var.fix_bott…

Hi Paul, If you say "delete", do you mean to remove an item from the experiment? If so, then, Spanne's ideas will do. However, if you mean, to present them on the screen and then hide a subset of stimuli from the screen, you need to do s…

Hi Christina, You have to give more detail on your implementation. What you want to do is definitely possible, so probably you made a mistake somewhere. Without knowing what exactly you did, it is hard to say how to fix it. So, please upload your e…

Hi Anna, I've no idea. But luckily google seems to know more: http://stackoverflow.com/questions/42987383/friedmans-test-in-r-gives-different-results-from-spss Hope it helps you, Eduard

Hi, Are these links maybe helpful? I think there were quite a few discussion on the RSVP paradigm, if you use our search function, you might find all the information you need in older discussions. http://forum.cogsci.nl/index.php?p=/discussion/168…

hI, I adapted your script a little, it should do now what you expect it to do. Note, I didn't solve the issue that you described (collecting 2 keyboard responses), instead it is possible to look at the responses afterwards and decide based on resp…
-
Hi, First of all, you could have a look at our tutorials. Getting familiar with the software is the first step to make your own experiment. Once you have a better understanding of Opensesame, you can give it a try and see how far you get. Once you…

Hi Mariana, Could you upload your experiment? It's a little tedious trying to think what could be going wrong without seeing your code. Thanks, Eduard
-
Hi Lucy, Check out the beginner's tutorial. It gives a great start into Opensesame, including also the solution to your problem (point 5 or 6, if I remember correctly). Good luck, Eduard

HI Silvia, According to this paper you can increase the sampling rate to 60 Hz and get samples every 16.7 ms. However, 1ms precision is not possible with the eye tribe. Unfortunately, I don't use the eye tribe myself, so I can't tell how to adjust …

Hi, Osmose: (Quote) Jarik: (Quote) Spot the difference... Eduard

Alright. Well, what you need eventually is a full path to the video file of yours, that you can put into the plugin with which you're going to play back the video. So, maybe coding it in a permanent way, would suit you? Before every time you load/pl…

Hi, (Quote) Yes, you can. See here: http://osdoc.cogsci.nl/3.1/manual/stimuli/sound/ (Quote) Yes, this is also possible. See here: http://osdoc.cogsci.nl/3.1/manual/forms/widgets/text_input/ Good luck, eduard

Hi Hanne, Did you try adding your files to the filepool and see what the performance is? It is true that a big pool can cause trouble, but this doesn't have to affect you much. If the performance issues are too severe, we can try to fix it. Eduard
-
Could you upload your experiment? It sounds like you moved your script too deep, but I'd need to have a look to be sure. Edaurd

Hi, Can you try to use following code in your script? ms = mouse()ms.show_cursor(True)# From then on, use the ms as response collection item (see here) Eduard

HI Amanda, Have you checked older discussions? Questions how to adapt a slider come up rather often. See for example these ones: * http://forum.cogsci.nl/index.php?p=/discussion/40/solved-implementing-a-slider * http://forum.cogsci.nl/index.php?p…

Hi, We need a little more information. What do you mean when saying "to input 'correct' answers?" Eduard
-
Did you try my code? It should work I think... kb = keyboard(timeout = 0) # initializes a keyboard response item with a timeout of 0 my_canvas = copy_sketchpad('my_sketchpad') # makes an empty canvasvar.correct_response = ['q','m'] # define what yo…

HI Christina, Your sequence is not part of your loop but is just called afterwards. You see what I mean? Make the sequence be part of the loop and you should be set. See also here for more infromation: http://osdoc.cogsci.nl/3.1/manual/prepare-run…

(Quote) That's exactly it. key presses that were pending from earlier, were triggering a response instantly when the experiment reached the keyboard_response item. (Quote) Probably.

Hi Robin, Why don't you just try? If it doesn't work, you can always move to inline_script. There you can do the same (actually even more) things and are more in control of the flow of your experiment: http://osdoc.cogsci.nl/3.1/manual/python/sampl…
