Basically what Josh says. But one thing to be aware of with the EyeTribe is that it's quite prone to losing the eye if you move the head a bit, and this an all-or-nothing deal. A good trick is to tell participants that they should be able to see the…

Hi Nikkie, The DataMerger is quite outdated by now. Below is a simple script that allows you to do more or less the same thing. The way it works: * Add all .csv files that you want to merge to the OpenSesame file pool * Add this script as an inlin…

Hi Dirk, If you select the multiprocess runner (Menu → Tools → Preferences), at least OpenSesame shouldn't crash entirely. The experiment will probably still crash, but maybe you'll get a more informative error message. If so, could you post that h…

I doubt that the Cedrus box will work with the SR Box plug-in, because that would mean that they have emulated the protocol used by PST (and why would they?). So if you want to use it, which is possible, you'd probably have to write an inline_script…

How about a joystick? I think joysticks/ gamepads are fine response devices. Of course they don't have the temporal precision of a dedicated response box, but in most cases that doesn't matter anyway. (Because the extra variance introduced by the re…

Hi Asma, Thanks for pointing this out. You probably have a column named length, right? Renaming this column to say _length, for example by opening the experiment in an older version, should fix the issue. This is clearly a bug, and I opened an iss…

Hi Asma, The crucial part of the error message is always at the bottom, so it's not visible in your screenshot ;-) You'll also find the stacktrace (i.e. the error message) in the debug window (Ctrl+D). Could you copy the entire error message from …

Hi Sazzy Babe, If you're having a meltdown, I would start by taking a moment to cool down. That's always a good start. ;) And then take a moment to walk through the beginner tutorial. This will explain the basics of OpenSesame, and it sounds like…

Hi Aaron, (Quote) As you can see on the page below, support for Tobii is labeled as experimental. And neither me nor @Edwin actually have a Tobii ourselves, so we cannot provide much support. On the other hand, there are quite a few forum users tha…

Hi Josh, It took me a while, but I've seen this problem too now. On Ubuntu 16.10. On Ubuntu 16.04 or 17.04 things work fine for me. Are you running 16.10 as well? I don't think you'll be able to properly find the cause of this crash. It's a low-le…

That would be really cool! Let me know if I can help in some way. Here's the Python script. I doubt it's very useful, if only because I wrote it as a chain of lambda expressions (brushing up on functional programming). But just in case. * https://…

Hi Moreno, It's a long discussion (which I haven't read entirely), but there are few fairly straightforward ways to implement counterbalancing. Both options below require OpenSesame ≥ 3.1. Selecting a source file based on subject number In the lo…

(Quote) It took me (as usual) a while to arrive at this insight, but: if I understand correctly, in the case of linear regression (or any set of models without interactions) the inclusion BF is the Baws Factor. It's just when interactions come in th…

Hi, This depends on how the plugin works. Plugins can have their own variables, for example to set plugin-specific controls. You can access these like this: items['my_item_name'].var.my_variable_name But plugins can also set experimental variable…

(Quote) Yes, that's correct. (My own example a few posts back was actually incomplete.) Below is what my script does. Say that we have an A×B×C design. Models with: * + contain the term of interest and are therefore included in the numerator * - a…

I noticed those posts, yes. For me OpenSesame install fine on Windows 10, and I'm not sure what it could be. (Quote) If find that unlikely, at least if you don't get an error message. I think it's more likely that it's copied to an unusual location…

I quickly looked into the two Baws Factors that don't seem to match the p values. (In the process I also corrected a bug, so I updated the table above. The difference is small, though.) For congruency×emotion, the Baws Factor is at least consistent…

Hi Jonathan, This looks like a compatibility issue with OpenSesame 3.0. But it also looks like you're running an old version of the plug-in. Could you see if simply updating to the latest version solves the issue? * https://github.com/dev-jam/open…

(Quote) Great, and thanks for letting us know!

(Quote) Yes, and each extension corresponds to a folder in (if I remember correctly) Lib\site-packages\share\opensesame_extensions. If you don't want an extension, you can simply delete its folder.

(Quote) There are three extensions that do network stuff. All three can be disabled through Tools → Plug-in and extension manager. * OpenScienceFramework. However, this extension doesn't go online unless it remembers that you were logged in (right …

(Quote) It took me a while to figure out what you meant, but I think I got it. If I understand correctly, it's simply this: B) = sum(P[M|data] for each A-model) / sum(P[M|data] for each non-A-model) Because there are just as many A-models als non…

Hi Nora, (Quote) Yes, with a short inline_script. Say that your variable is response, and you want to re-execute the form (my_form_item) until this variable has the value 'yes'. Then you could do this by inserting the following into the run phase o…

It sounds like your browser is blocking the download for security reasons. There's probably an option somewhere to disable that. Or simply try a different browser. I assure you: You can download the newest version!

(Quote) (From this discussion.) Well, to paraphrase the creationists, probability theory is just a theory ;) No, but of course: I'm sure inclusion Bayes Factors have a valid interpretation in terms of probabilities. But this interpretation, or so i…

You're running Ubuntu 12.10 (Quantal Quetzal)! This is a very old distribution for which support ended in 2014—official support by Ubuntu, I mean. I would definitely upgrade your system, because right now you're not even receiving security updates …

Hi Kat, This plugin, the media_player_vlc, requires that you have VLC player installed in the default location. You can get VLC player from here: * http://www.videolan.org/vlc/index.html My recommendation would be, though, to figure out how to in…

(Quote) You would think so. I actually started writing a book about it; it had a cover and everything. But when developing it into a full-length story, I found that the theme is a bit limited after all. And also some trouble with my muse, etc. You k…

Hi Erwin, The easiest workaround is probably to run the experiment in a window, but have the window cover the entire display so that it's effectively full screen. You can do this as follows: * Select the legacy backend, and click on Backend Settin…

Hi Tyler, Installing OpenSesame just from the PPA is fine! Pip installing it as well doesn't hurt in principle—but it can make things very confusing. OpenSesame should run straight away, so something is funky here. What distribution and version of…
