  • 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 t…
  • 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 margin…
  • 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 add 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 way…
  • 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 'if …
  • 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 automat…
  • 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…
  • Hi Marios, Non-latin alphabets can be problematic and text input in forms is notoriously slow. A couple of questions -is it possible to have a look at the experiment (or a simple example experiment that demonstrate the issue) that would make any …
  • Hi Marton, Would it be possible to have a look at your experiment? It is difficult to understand how it is set up by just reading how all the items are put together. As I understand it the sequence for a single trial it as follows: 1 list of wor…
  • Hi Anna, I think the document is recovered, and saving it with a legacy backend seems to solve the bug on my windows set up, not sure if you are using windows or mac. Images are now separate, if you put them in the same folder as the experiment it…
  • Hi Amir, That looks great, and it works quite smoothly for me, even with xpyriment backend. Kind of odd that the widgets work slower though, since the plug in seems to make use of the same package, but via a different route. Perhaps one thing that…
  • Hi Vatsal, 1. If you want to avoid errors that relate to the prepare phase that is mandatory in the sketchpads, inline scripts would solve it, but this needs more coding. 2. Yes, the if-else is not clear; use brackets, or split in multiple lines …
  • Hi Vatsal, The printscreen looks like it is from opensesame 2.0, since it has the 'old look', however, the experiment you attached works now, and I get indeed an index error. What is happening is that tar sometimes remains empty: [8] [] this is t…
  • Hello Vatsal, In your experiment I see everthing in the unused items area, like this are you sure this is the right version? (otherwise something is wrong on my end) As for the error: it'll be handy to see the error message; but I guess that wo…
  • Hi Inakigil This should work: [count_new_sequence]=0 where new_sequence is the name of you sequence item, also turn 'evaluate on first cycle off' since the variable does not exist on the first run. There is also another way, in which you create …
  • Hi Kevie, there are several ways in which you can log the variables. I guess since timing is important, it might be best to record all the key presses in one while loop and then set the responses to be logged afterwards, since logging a variable du…
  • Something like this might work: timeout = 5000 c = canvas() c.text('test here some keypresses for %s seconds' %timeout) from openexp.keyboard import keyboard import pygame kb = keyboard(exp, keylist = [],timeout…
