  • Hi Scroon, Sounds like a nice idea, I send you an email Roelof
  • update: when upgrading scipy to latest version (1.1.0) the experiment runs psycho backend fine, in both opensesame versions 3.1.9 and 3.2.5, the exact change that lead to the solution is still obscure, but it is working atm
  • Hi Sebastiaan, Thanks for the response, after we were able to reset the policy groups we got access to the graphic card settings and its seems as if something was wrong with the v-sync settings there (on auto instead of simply 'on'), when we switc…
  • Hi Sebastian, Thanks for the advice, I tried upgrading scipy to version 0.12 or version .19, but to no avail. I did discover that python was executing in 64 bit, which I changed to 32, but it did not solved the problem, although the systems on w…
  • Perhaps also of importance: the error occurs only on a specific desktop, the same standalone opensesame version (ran from usb) works fine on my own laptop
  • Hi Sebastiaan, Thank you for the response and suggestion, importing the module on its own (import scipy) gives no errors, but importing the specific module gives: from scipy import optimize ImportErrorTraceback (most recent call last) in () …
  • Hi Marton, The log needs a list of strings with variable names, like so: var.bropper = 1 log.write_vars(['bropper']) I agree the documentation is somewhat unclear, hope this helps though Roelof
  • Hi Marton, you could probably use a coroutine, but this would also have to be customized, so it would not necessarily make life a lot easier, I also have not worked with co routines before, so I cannot provide clear insights here. And as far as I u…
  • there's a reply in the original thread, thank Eduard for the heads up
  • Hi Marton, I've been away from the forum for a while, hence the tardy response. Your experiment still makes use of timings that loop over the sequence item. All the recall canvases and button responses should be prepared in advance and be shown i…
  • Hi Matanel, If you only want to check the first block after practice, you could set up three loops 1.practice, 2.check block, 3.rest of the blocks, and then only run the third loop if the accuracy for the check block was high enough, if you want…
  • Right, but just to check again; you changed the fullscreen in the backend settings to yes? And you are starting the experiment using the run full screen (green single arrow) button? Lastly, what would you like the behavior to be? I think indeed fu…
  • Hi Cogexp, would it be possible to have a look at the actual code instead of an image, otherwise we would have to retype all the lines to check what is going on. Roelof PS: I am also not sure what " selecting a ** red circle** from a base of pixel…
  • Hi Ad, I think if you reduce the spacing to zero it should work, Roelof
  • Hi Anita, I personally don't know much about this topic but maybe @sebastiaan knows more? Roelof
  • Hi Ad, The form is actually not slow as far as I can see, but the radio buttons for the questions are not active everywhere, since there are a lot of questions the buttons get bunched together, which means you are only able to click on the top part…
  • Right, that is somewhat odd; just to check; you changed the fullscreen in the backend settings to yes? And you are starting the experiment using the run full screen (green single arrow) button? (Also, which operating system are you using? and which…
  • Right, I am not sure I understand, you do not want the participants to view the questionnaire full screen, but present a specific pop up window in a specific location?
  • The way to place the items on the screen are determined by these two lines: set rows "1;1;6" set margins "50;50;50;150" # --> top:left:bottom:right The first line sets the relative spacing of the different items, the second line sets the marg…
  • Hi Patricia, There is a way to set a standard background image; but this only works smoothly in 3.2: http://forum.cogsci.nl/index.php?p=/discussion/3531/forms-widgets-image-as-background-for-form For the moment it seems much easier to just a…
  • Dear Patricia, Apologies, I was not aware of the template, the template does indeed use a 'text_form input'. The "Open question" comes from [question_text] this refers to the variable 'question text' in the loop table, you can either delete this t…
  • Dear Patrica, As far as I know there is no questionnaire plug in, however there is a plug in for text called "form_text_input", and I am guessing you are using this. If this is the form you are using, then the stub can be changed by clicking on th…
  • Hi Jane I cannot help you with the problems unless we have some more information: The code looks pretty solid (there is a superfluous indent on line 4 though), I assume that ResponseEffect is somehow connected to the feedback sketchpad, if so in wh…
  • Hi Stef, If you put the names of the video in the blockloop as a variable, you can use the notation [name] in the mediaplayer and it will recognize the video name, the attachment an example, good luck, Roelof
  • Hi ocraneri, I am not sure I understand the structure of your experiment, are there multiple responses for a single trial? In that case it might make sense to create multiple response variables and log of of these at the end of the trail, this w…
  • Hi oasistree, I think your idea was very good, in attached an example of how it could work, not sure if this looks anything like your experiment, to give more precise advice it'd be handy to have a look at the script. But in general using an 'i…
  • Hi Athann, Using the code from the other forum thread you posted I made a little example of how it could be implemented, you have to be a little careful with the names of your loggers since when they are customized the subject number is not autom…
  • Okay, the git example makes thing a lot clearer: "timing can only be accurately controlled within a sequence" The structure you have here always runs into preparation time since every sequence will need to be prepared. What needs to be done is put e…
  • If I understand correctly, you need the response window to be limited to 30 seconds, always, regardless of individual participant, but in order to achieve this limit you check the average response time in training phase: and use this as an indicat…
  • I do not know how development on android is developing, however, I know there are some simple measures to separate images between eyes, e.g. the mirror stereoscope (used here: https://www.researchgate.net/publication/269820348_Reinforcement_of_perce…
