Hi Elizabeth, Are you using the PsychoPy back-end for your experiment? I forgot to mention that with PsychoPy (0,0) is at centre for the mouse coordinates. But in contrast to the sketchpad item, coordinates above centre are negative. If you're not…

Hi Dror, To upload your experiment you could do the following: * Open the "General properties" tab, click "Script editor" and copy the whole script, * go to pastbin.com or gist.github.com, upload your script there (simply paste…

Hi Dror, Of course. By adding an additional if-statement (see line 6 in the script below) you can apply the remainder of the inline code only to certain items, in this case a sketchpad called "reversed": [pastebin:eRffgRbP] For the comp…

Hi Thijs, A happy new year to you too! Glad to hear that the experiment is almost working. With regard to your log file, could it be that you placed the logger item somewhere else than at the end of your trial sequence? For example before rather …

Hi Mark, Welcome to the forum! If I understand correctly your trial sequence is as follows: * Firstly, you present a stimulus (a pair of eyes). * Secondly, participants rate this pair of eyes on a 1-5 rating scale. * This is followed by a blank i…

Dear Guido, The fact that right-shift key presses are coded as 'lshift' is a known issue, see this previous thread. Like you mentioned, this occurs only with the PsychoPy back-end (and solely when running experiments on Windows, on Ubuntu right-sh…

Hi Dror, I would like to refer you to a previous post where Ezer asked the same question: * http://www.cogsci.nl/forum/index.php?p=/discussion/70/solved-hebrew-text In this thread Sebastiaan provided a piece of Python inline code which you could …

Hi Elizabeth, Will these be the same as seen on the sketchpad? No. Mouse coordinates have their origin (0,0) at the top left corner, whereas for sketchpads (0,0) is the center. Do they change depending on screen resolution? The size one pixel (t…

Hi Thijs, Welcome to the forum! Yes, you can certainly create your experiment by using OpenSesame. If I understand correctly, your trial sequence is as follows: * Firstly, a still frame is presented containing a number of stimuli. Which of the s…

Hi Masoud, If I understand correctly, your trial sequence should be as follows: * Firstly, you have a sketchpad that contains a fixation dot and a pair of words, one presented to the right and one presented to the left. * Next, you have second ske…

Hi Michel, Would it perhaps be possible to upload your experiment? Although your explanation is very clear and obviously rules out some possibilities, it is still a bit difficult to find out what might be causing the delay without seeing the experi…

Hi Sylvia, You're welcome! And good to know that your experiment is finished! Feel free to ask any more questions in the future! Lotje

Hi Masoud, You're right! I forgot to mention that setting system fonts is possible from OpenSesame 0.27 onwards. For OpenSesame 0.27, a lot of effort has been put into making OpenSesame friendly to non-western alphabets. I would therefore recommend…
-
Hi Masoud, If rectangles instead of letters are displayed this indicates that the font is not correctly set. As you probably already know, you can change the font like so: Click the font-family combo box and choose "other ...". Next, sele…

Hi Sylvia, Some variables in your log file have the value 'None' since you log them before the corresponding question is shown, and therefore before the participant gave a response. This is because you set the run-if statement of the form_base item…
-
Hi Jákup, What is the item you want to count? And when do you want to reset it? If, for instance, you want to count the number of trials and reset this counter at the beginning of every new block, I think the code Sebastiaan posted above should wo…
-
Hi Sylvia, Did you already obtain the latest pre-release (currently 0.27~pre26) as described here, to see whether this solves your problem? If updating did not help, you could perhaps upload your experiment here. Then we can have a closer look at …
-
NOTE: the answer was edited after being posted. Hi Michel, There are three problems with the if-then statements in your script: Firstly, note the following general rule: When assigning a value to a variable, use =, the assignment operator, like …
-
Hi Jakúp, OpenSesame interprets values in the simplest possible way: * Firstly, if the value could be treated as an integer (the most simple type), OpenSesame does so. * Secondly, if the value cannot be an integer, but it could be a floating point…

Hi, Although your solution works, you could achieve the same result in a simpler way, too. You could use the set() function (like all experiment functions) in a Python script in the same way as you used set_subject(). Like so: # Determine the va…

I'm glad to hear your script works! :) Don't hesitate to post any further questions you may have!

Hi, You can import (functions from) Python modules in several ways. How to call a module's function in your script depends on the way you've imported it. If you imported the function shuffle from the module random by using the 'from ... import' sy…
-
Hi Anna, You will need a little bit of Python inline coding to have a random rather than a fixed stimulus duration. This can be achieved very easily as follows: * Append an inline_script item to your trial sequence and place it before the sketchpa…
-
Hi Dirk, Keyboard presses are not always identified exactly the same across back-ends. The 'List available keys' button in the keyboard_response item therefore contains a list of all available keys adapted to the back-end you're using. To start wi…

Hi Johannes, I'm glad to hear the sound problem and even the other problem are solved! The idea behind Expyriment back-end is to replace the legacy back-end with a new one that is just as light-weighted and simple, but in addition has timing prope…
-
Hi Johannes, You're not doing anything wrong! What you're describing is a known problem with OpenSesame 0.26 and should be fixed in 0.27. I would therefore recommend to download the latest pre-release, which should be fairly stable at this point. …

Hi Boo, Thanks for the script. When I run your experiment on Ubuntu it works perfectly. However, when running it on Windows, right-shift responses are indeed detected as "lshift". This occurs only with the PsychoPy back-end and probably h…
