Hi, Could you share your experiment with us? The tutorial should work even with the most recent version of Openseame, so I suppose something is going wrong. Eduard

Hi Shaked, Could you share your experiment with us? I don't have experience with that particular problem, so I'd need to try it, in order to figure out what is going on. Eduard

Hi Matanel, Is this question here different from the one you asked in a separate discussion? If not, I'd like to discuss it centrally in the other discussion instead of in both. Let me know. Eduard

Hi, In theory, you can simply build your experiment from within an Opensesame inline_scipt, relying completely on PsychoPy, e.g.: import psychopy# do psychopy stuff But that's probably not what you want, because you basically don't use Opensesame…

Hi matanel, Would you mind giving a little more detail on what exactly it is that you want to accomplish? In particular, what is Scales supposed to mean? Maybe uniform coordinates could be useful to you. Eduard

Hi Agata, Unfortunately, I can't really help here. I have never worked with Emotiv and Test Benches. Are you using Psychopy directly, or did you program your experiment in Opensesame with the psychopy backend? Did you try ask at the support of Emo…

Hi, Can you maybe elaborate a little what exactly it is you need? The first line in the logfile will contain the time of the first stimuluation, provided that you store the time stamp of that occurrence. Eduard

Hi Jessica, Check out this file. Page 30 and 31 should give you the information you need. Good luck, Eduard

Hi Cathi, Could you upload your experiment? Then, I can help you quicker. Thanks, Eduard

Hi Sadek, In the first item in the overview area (usually called Experiments), you can specify foreground and background color. Can you check whether you selected the right colors there? If this doesn't solve the problem, could you upload your expe…

Hi, Opensesame used to have a Staircase plugin, but I don't think it still is maintained. Implementing it shouldn't be too difficult though. Maybe this discussion provides you with a nice starting point: http://www.cogsci.nl/forum/index.php?p=/dis…

Hi, Does the variable response have the information yo need? I bet the data is somewhere, just look through your file and see whether you can find it. Eduard
-
Really? It does happen when I do it. I have no idea what could be the reason for that. Btw. I used the legacy backend. In case that matters. Sorry.

Hi Marina, Regarding your first issue, if you set the duration of the sampler to 0, you get the corresponding action for each keypress. (the tone is still presented for 300 ms). Aside of that, I recommend you use the same (linked copy) of your keyb…

Hey, Maybe that is a little more feasible, but the current answer stays the same: Not possible at the time. But I encourage you, to put it on the wishlist, or even make a feature request on github. It could be a useful addition to Opensesame. Edua…

Hi, To get a working var.correctvariable. You have to change the line: correct_response = 2,3 to correct_response = [2,3] and add the line var.correct = last_response.correct at the end of the inline_script. Hope this helps, Eduard
-
Hi Thorsten, Yes, you are absolutely right. If the delay is bigger than the desired ITI, you can't have a dynamic prep time. So probably, you will have to prepare your trials in advance (moving all preparations into an earlier sequence and just in…
-
Hi, If you have no other variables that you manipulate systematically within a block, you can create a variable called feedback_presence and set it to no 43 times and to yes 5 times. Inside the block loop, you would then pop from a list of possible…
-
Hi Marina, (Quote) I suppose you present the second image contingent on a correct response? So, in no_response trials, the correct response is no response, not one of the response keys, right? If you specify that on no_responsetrials the second ima…

Hi Boris. You are looking for a Text input form Good luck, Eduard
-
Hi Cluu, As a starting point, you can try to follow the step-by-step-tutorial. Presenting sounds and images are covered there. The procedure with forms, you can look up here. And audio recording here. This should get you started, but if you get s…

Hi Amir, @labovich has set up an OSF repository for Opensesame experiments (http://forum.cogsci.nl/index.php?p=/discussion/2888). Is this what you had in mind? Eduard
-
Hi Amir, I think what you describe is implemented in PsychoPy. There you can graphically design your experiment and the python code accompanying it, is produced on the fly. However, as far as know, this is not possible in Opensesame. If you really…

Hi, Could you upload your experiment? Then I'll have a quick look at can check what is going on there. Thanks, Eduard
-
Hi Neon, It depends. In my experiments, it took usually around 450 ms to start/stop a recording. Other people found other delays. But if you are interested in the exact numbers, you should test it yourself (take the time before and after starting/s…

Hi Michele, Maybe there are easier solutions, by actually manipulating the video presentation, but what comes to my mind first, is making a screenshot, and present that screenshot in a sketchpad together with the buttons. To get the screenshot, yo…

Hi, That will definitely quite a bit of python coding. Check out this discussion here on the forum: http://forum.cogsci.nl/index.php?p=/discussion/3069/drag-and-drop-feature-for-os There are probably many pygame examples out there: This here for …
-
The consequence of not changing them depends on how you analyze the data. For example, if you define regions of interest, based on degrees of visual angle, you will have incorrect regions when the screen parameters are off. Perhaps, it might also af…

Hi Thorsten, Have a look at the first few paragraphs of the documentation. There the reasons for your delay is explained. In short, Opensesame assumes everything within a sequence is time-critical and tries to minimize the delay between items in i…
