Hi ke, You could place a logger after each individual questionnaire item? Cheers Josh
-
Hi, sorry about that, I forgot that response_time should be in brackets: [response_time] Cheers
-
Hi, You want to place the keyboard item in between two blank screen sketchpads. The first sketchpad has a duration of 0 ms, the keyboard item has a timeout of 1600 ms, and the second sketchpad has a duration of 1600 - response_time. That should wo…

Hi, You may want to have a look on this page: http://osdoc.cogsci.nl/3.1/manual/eyetracking/pygaze/ You have to use the pygaze components to make your eye-tracker work with OpenSesame. How your datafile will look depends on the type of eye-tracker…

Hi Carine, Within the trial sequence, you'll want to have 5 keyboard response items, all with an infinite timeout duration. It would be best to intersperse these keyboard items with inline scripts, wherein you add the latest response to a string of…

Hi Boris, are you using inline scripting? Cheers Josh
-
Hi Christophe, Are you planning to make an experiment that uses sounds? In that case, a sound card would be a useful thing to insert in the experiment computer. Alternatively, it could be that you get this error message when starting up OpenSesame …

Hi Titus, Since OpenSesame is python-based, things such as writing data to a file should work in a manner similar to how it's done in a regular python environment. Might it help to include the full path when initiating your df file? Cheers Josh
-
Hi, It seems as if you're trying to use a string (line of text) somewhere in your experiment where you're missing a quotation mark. Are you using text in your experiment? Cheers Josh
-
Hi, A few things: firstly, your start time variable is called t, but further on you're using t0; this could be your problem. Secondly, it seems that you want to count all clicks, with i+1. Do you have i initiated somewhere? You could for instance a…

Hi Mikael, So if I understand correctly, you've already put the inline_script before the Image sketchpad? In the picture it's still placed after the sketchpad. Cheers, Josh
-
Hi Neon, There are multiple ways to implement these things. With regard to the first question, you could simply split your loop item in two - as in, you'd use two loop items instead of one. The first loop item would contain numbers 1-5 and the seco…

Hi Candice, As far as I know this is still not possible, unfortunately! Cheers, Josh
-
Hi Mimi, You say you have watched several tutorials. Have you also actually done one? I suggest you do the Cats Dogs & Capybara's tutorial. It works with sound samples and may have a structure similar to the one you envisioned. Cheers, Josh
-
Hi Michel, If you haven't defined a variable whilst trying to call it in a break-if or run-if statement, the experiment should definitely not run and you should get an error message that states that your variable does not exist. It seems that some…
-
Hi Agnès, The keyboard response is stored in a variable named response. You could place a sketchpad item right after your keyboard item, and insert text in it. Clicking the middle icon out of those three icons in the top-right corner of the sketchp…
-
Hi, I think this will inevitably involve a small degree of programming. You have to create a list variable to which you append every completed sentence, so that those sentences can later easily be called. To do this you'd put an inline_script right…
-
Hi Maria, It seems as though you have no complete filename. You're trying to call '.png', but I doubt that's name of your file? Are your pictures in the filepool? Cheers Josh
-
Hi, As OpenSesame is python-based, being able to run python would be a prerequisite. A google search suggests that chromebook users may want to install 'Crouton' (e.g. https://www.reddit.com/r/learnprogramming/comments/2qay0a/programming_with_pytho…
-
Hi Vatsal, What's your question exactly? I don't think you need inline code. Touch responses are logged with the touch response item. In order to be able to log anything (e.g. your anticipatory response) from the moment the stimuli are presented un…
-
Hi Joanne, Could you copy-paste the notification in here? We'll also need more details, e.g. your python code, and structure of the loop item. Cheers Josh
-
Hi, What kind of image are you using, and how did you insert it? (Extension, file pool, etc). Some more details would help. Cheers Josh
-
Hi, Pygaze doesn't have this functionality I'm afraid (pygaze is for gathering eye position coordinates with an eye-tracking camera). This will thus require some programming. Maybe somebody on the internet happens to have a decent algorithm for thi…
-
Hi Arpit, There's the possibility to log eye-tracker data in regular logfiles, by just creating variables that contain those data (make sure your logger logs every variable though). This would be fitting if you need coordinate data fot specific tim…
-
You will need a loop either way. If your trial consists of e.g. a circle in a certain color, then another circle in a certain color, and then a response, you'll need two sketchpads and a response item in a sequence item. That sequence item can be pl…
-
Hi, By default, the feedback item resets feedback variables. This needs to be turned off (in the trial sequence) if you want to have feedback at the end of your experiment I think. Cheers Josh
-
Hi Emma, I've just answered this question in your other post, so I'm closing this one
-
Hi Emma, you'll have to use the inline_script item, and include the lines of code as indicated by the manual (and in the example I gave above). You thus build your screen using that code, and then you actually show the canvas by inserting my_canvas…
-
Hi Alice, you could insert a sketchpad somewhere, with keypress as the duration. In the sketchpad you can insert something like a break instruction. You can place this sketchpad between blocks (if you have multiple blocks and you want to break in be…

Hi, If I understand correctly, you first want to show a circle in one color, and then in the other color? You'll need to use two sketchpads for this. Out of curiosity, why would it be problematic to use two sketchpads? Cheers, Josh
