Hi @hulya, Thanks for reaching out, and congrats on starting a PhD! From what I know (but @sebastiaan would be able to confirm or correct me), the Android runtime is no longer available because it was based on third party software that is no long…

Hi @bssengul, It is not clear frmo your description what the issue may be (not sure what you mena by lists, or example). You may want to check that the jpg filename you are calling is spelled exactly as the filename (case sensitive). Can you upload …

Hi @hwon, Thanks for clarifying your question. To asnwer you question, the "time_" variables correspond to the time stamp for different objects (see https://osdoc.cogsci.nl/3.3/manual/variables/#experiment-variables). You can think of it a…

Hi @noob768, Not sure I understand your question. The example I provided above presented two blocks in counterbalanced order across participants. So, you can use it to present a difficult and an easy block to participants, with half the participants…

Hi @hwon, I'm not sure I understand your question. If you want to measure a response time for a mouse click after a sound has played, you simply need to set the duration of the sampler to the sound's duration and place the mouse response object just…

Hi @noob768, You can find a simple solution to this problem in the forum: https://forum.cogsci.nl/discussion/8562/counterbalancing-blocks-for-participants Hiope this helps, Fabrice.

Hi @Pari, I'm no expert on that sort of issue but I wonder whether if you got any error message during the installing of pylink in the OS Console. You could try running the following in the OS console: pip install --no-cache-dir pylink Does that hel…

Hi @sflu, You could try that method, but the "Break if" method runs full trials and then examines whether the loop should be interrupted. So if you have a long sound, pressing a key would not stop the sound right away. If you want to use a…

Hi @T_Q, From OpenSesame, just paste and execute the following code in the console: import pip pip.main(['install', 'opensesame-plugin-audio_low_latency']) Then close OpenSesame and reopen it. The plugin should now be visible. Best, Fabrice.

Hi @sflu, Indeed, the sampler's keypress or mouseclick end event is not operational when you run the experiment in the browser. This makes it a little tricky to stop a actively sound, but I could think of at least one way around that problem. It doe…

Hi @Orimflow@Orimflow, Only had a glance at your code but the logic is correct, yes. It might introduce some variability in the timing accuracy because of the code and loops involved, but the general idea for the method makes sense. Something like t…
-
Hi @Orimflow, Based on your description, I think you can achieve this using a co-routine like this. https://forum.cogsci.nl/uploads/528/NGJSN5NFYB7F.png You'd need to use the response_time and response variables for the individual keyboard events to…
-
Hi @noob768, That depends on your design and what you're trying to achieve. The simplest way to fix the issue you posted earlier is to include details for all stimuli in your loop but to either use a jpeg that simply consists of a picture filled wit…
-
Hi @noob768, I believe that the problem is that you're trying to draw things that you have not specified. Here's what you are drawing in your sketcphad, for every trial: https://forum.cogsci.nl/uploads/785/DSB8D6A2D4ZG.png 8 objects in total, pullin…

Hi @Siyang, I'm no Javascript expert myself. I usually do basic searches in Google. the W3school website can be a good place to start (https://www.w3schools.com/js/). Best, Fabrice.
-
Hi @Siyang, One solution would be to chage the resolution of your experiment to match your screen's resolution. n my case, my screen is set to 4K, so the following settings will make the whole screen black after I press F11 in the browser: https://f…

Hi @m.vel, I haven't used it myself, but you may find the following thread useful: https://forum.cogsci.nl/discussion/1772/detecting-voice-onsets-voicekey/p1 Best, Fabrice.

Hi @Lajov, @eduard is right ("No, it isn't. It will work just as well with randomized sequences."). Have you tried it? Just change the loop to random and you'll see that it stops for a break after 5 trials. As Eduard pointed out, whether t…

Hi @jennysimps, I think there's some confusion. This forum is about OSWeb, not website design... Fabrice.
-
Hi @Pari, One simple way of achieve that is to include both of your blocks (color_block and shape_block) into a higher-level loop with 2 rows, and to use some code to store identifiers for the two conditions in an order depending on the subject numb…
-
Hi @Lajov, The simplest way to do this is to insert the sketchpad or events you want to use as the break into the sequence of your trial, and use the "Run if" function of these objects to condition them to run under certain conditions. In …
-
Hi @anth , Tasks don't run the same way in OS and through the browser. My advice is to use Javascript to print variables to the console in your browser to try debugging it in the browser first, making sure each variable is logged properly, then chec…
-
Hi @anna_st, If you don't want participants to skip a response without providing some response, you should place the form insde a seuqence inside a loop, set the loop to repeat say 10 times, and set a "break if" condition so that the loop …
-
Hi @Jordan, Not entirely sure I follow your description. When you're referring to "words", are you referring to what appears under the "Stim_word" variable or under "Stimulus"? I'm gonna assume that you meant the second…
-
Hi @anna_st, I'm not experienced with this, but you can achieve it by using the inline_html object (information on how to use it here: https://osdoc.cogsci.nl/3.3/manual/forms/html/ and searching the internet for information about HTML forms). https…

Hi @sflu, From your screen shot it appears that you're using a Python inline_script, but Python is not supported in OSWeb. You need to use Javascript instead. Youo can modify your program without upgrading to version yet. Fabrice.
-
Hi @sflu, I just saw your post (when replying to a message, it is best to user handles: @sebastiaan so that your correpondent receives a notification). Yes, the sound will carry on beyond the 400ms of the sampler. I believe that the error you mentio…
-
Hi @thescentofhoney, The procedure described in the tutorial is working. Could it be that you made some error copying it? Are you using a feedback object instead of a sketchpad? (only the feedback object is put together on the fly during the trial; …

Hi @DTG, Thanks for upoloading your task. I had a look but the RTs I get with it seem correct. I did the task roughly controlling my RTs and the values displayed fitted. When I responded extremely fast, I got extremely fast RTs. It is possible to pr…

Hi @DTG, It looks as if somehow the task is picking up something else then the response to the dot, but it's difficult to pinppoint the problem without examining the task. I've done a quick simulation of your design and got it to work and produce RT…
