Hi Sylvia, As far as I can see, you cannot specify a time duration after input until the end of the item. However, you can circumvent this issue, by adding an inline_script after your text_input item in which you sleep for the desired amount of tim…

If it is really entirely random, the name doesn't matter. For simplicity sakes, you could go for ['image1.png',..,'image84.png']. Then just randomly pick one and load respective image. If the category should be still retrievable, you could still hav…

Hi, If you have the rights to write on that server, you can simply install Opensesame there. Depending on the operating system of the server, the procedure will vary slightly. Probably, it is best if you used a portable version of Opensesame. Once…

Hi, Which opensesame version and which operating system are you using? I can't reproduce the error. Maybe you could also upload your experiment? Thanks, Eduard
-
Hi Anna, Would you mind uploading your experiment? Then I can check whether this is really a weird bug, or whether something else is going wrong. Thanks, Eduard

When he dragged a sketchpad into the overview area, it appeared there twice, each of them with the same label.

Hi Ellot, This video indeed helped. When I tested it, I only tried to change the variable names in the title, not really inside the body of the sequence. Now, I could reproduce the error, quite reliably actually. It seems it occurs only for some it…

Hi, Nope, I can't reproduce it on Ubuntu 14.04. Later today, I will try on a Windows machine.

Hi, I think this link might be useful to you: http://osdoc.cogsci.nl/3.1/visualangle/ (VIsual angle and eccentricity are the same) Good luck. Eduard

Hi Xeonen, If you need to do on the fly computations, you need to use the run phase. If this doesn't work, there must be an error in your implementation. Unfortunately, I can't help if you don't provide more information. What would be the error mes…

Hi Jonathan, The error message is right. -1 is indeed not a valid variable name, because python variables are not permitted to begin with numbers. What you meant to do is this: var.set('valid_side',var.valid_slide*(-1)). However, an easier and more…

Hi neon, I don't really get your distinction between "putting an image in the sketchpad" and "selecting an image" . However, I don't think this problem is unsolvable. Could you provide more information on how you call the images…
-
Hi, To quickly point you towards the correct answer, you can have a variable in your loop table, called e.g. cue_identity which can have the values circle and rect. Then later you present the cue in a sketchpad by drawing a rectangle and a circle a…

Hi Moreno, I hope I haven't misunderstood you. Attached you can find an example of the structure that I had in mind. Let me know whether you like it or not (and sorry for the late response). Eduard

Hi, For one, I think your loop table is a little convoluted. You have three independent variables: 1) target location : left vs. right 2) Target congruency: valid vs. invalid 3) Cue type: left, right, no, both Together you have 2 x 2 x 4 = 16 uni…
-
Hi Stephan, How about you put your code into a while loop and in which you keep on sampling key presses e.g., kb.get_key(timeout=10) (After which you flush the keyboard, to get rid of pending key presses). For every key press you append the key to …
-
Hi, This experiments sounds nice and is perfectly compatible with what Opensesame can do. ALso, I think it is rather easy to program it yourself. So, if you give it a try, browse through forum and/or the documentation, look at some examples, or jus…
-
Hi, Did you have a look on the beginner's tutorial? It describes a cueing paradigm that is quite similar to yours. If you add 4 times more valid trials than invalid trials to the loop table (just by adding lines), 80% of your trials will be valid a…
-
Hi Laurie, First, yes, it is possible to have a dot - probe task in Opensesame. Please have a look on the documentation site and the beginner tutorial first. The explanations there how to get images on the screen are rather straightforward and I a…
-
Hi Arturo, Probably you want to save the variable as var.response_moment = self.time() - start_time. This should make sure that the variable is written to the logfile properly. Eduad
-
Hi Mike, Can you upload the experiment or give more details on the structure of your experiment? From the information you gave it is hard to tell what is going wrong. Thanks, Eduard
-
Hi Moreno, Depending on the details of your experiment, it could work for you if you had only one generic loop, in which you present condition 1 through 4. In the beginning of your experiment you could have your lists hard coded and use the subject…
-
Hi, (Quote) This information you can access with var.subject_nr (Quote) That's a little trickier. Most importantly, I don't really understand what you mean with "items in the sketchpad". In general, you could do following: orig_list = …
-
Hi, It's never too late to start learning how to code. There are plenty of nice Python tutorials online. Your mistake, is that you don't adhere to Python's indentation rules and that and else is always followed by a colon. Also, your code is a lit…
-
Hi Charlotte, This is a little tricky, but not impossible. At any rate, you would need to use inline_scripting. The general idea would be something like this: * draw two squares that are fixed on a canvas * in a loop the following steps:* copy th…
-
Hi Evans, This is indeed a bug. However, there is good news. This error was reported on Github and has already been fixed. So your options are: 1) Update Opensesame to the most recent version (3.1.3) 2) use non-numeric responses Hope this helps.…
-
Hi Margriet, the error message does not say that a file called "slider" is missing, but that an item in your experimental structure is missing. This sounds a little weird, though. Would you mind uploading the experiment, so I can have a c…
-
Hi, This could be an option. Assuming that you have a variable that keeps track of the number of correct responses, something like that (in the break_if field) will work: [no_correct = 12] Of course, if you have nested loops (e.g. a trial loop in…
-
Hi, First of all, I am not familiar with Tobii eye trackers. Assuming that the works in a similar way as Eyelink eyetrackers, the following advice might be useful to you: (Quote) Yes, you can recalibrate a subject, every time your experiment is ex…

Which OpenSesame version do you use? Could you post the entire code you're using right now(e.g. uploading it on pastebin.com) or even the entire experiment? Thanks, Eduard
