Sorry I am a complete newbie at psychopy/pavlovia. I have create a survey in Qualtrics which randomly assigns a participant ID, but would response ID work better if the data can be transferred from pavlovia to qualtrics? I am aiming to then embed the Pavlovia link with in qualtrics. I have seen that…

I am still having some issues with psychopy. I have imported an already made Simple Reaction Time Task (by Deary & Liewald, 2011) into psychopy, but it does not look to be measuring in milliseconds on the excel data sheet…nor do I understand which is the actual reaction times and if an average is be…

By default, reaction times are in seconds. What I’ve done recently for a Stroop task is: Begin Experiment in JS only code median = function (values){ if(values.length ===0) return 0; values.sort(function(a,b){ return a-b; }); var half = Math.floor(values.length / 2); if (values.l…

Is there any way to change it to milliseconds in the psychopy builder? My knowledge of coding is non-existent.

I don’t know a way of changing the settings for PsychoPy components, but it’s easy enough to save an extra column in milliseconds. thisExp.addData('RT',round(key_resp.rt*1000)) The -500 in my previous code was use to a .5 second fixation at the start of the routine.

Unfortunately when I add the code in the beginning and change the key_resp appropriately, it won’t run and generates this error code: thisExp.addData(‘RT’,round(mouseResp.rt*1000)) AttributeError: ‘Mouse’ object has no attribute ‘rt’ Experiment ended. This is the same for when I insert this code: …

Have a look at this thread for mouse reaction time code. [image] Timing Accuracy Variable Builder Hi guys! I’m new on PsychoPy and new some of your help slight_smile What my experiment does? My experiment shows 2 images for the participant and 2 response op…

Would I include that code as well as the other codes mentioned above? Or just that one?

I added that code in and it is recording in milliseconds, hurray, thank you! Now the question is how to add coding to specifically average 12 T to 31 T on the excel document to transfer in the custom URL to Qualtrics (the “Main” reaction time task, where as the smaller data collection is the practic…

Ive tried to add some coding to generate an average from the mainTrials specific loop, but it keeps coming up with an error stating that mainTrails is not defined. I have had a look at the other forums, but I am still not sure why this error code is appearing. Here is my code, with the new average r…

I am still stuck on this and cannot seem to get it resolved. I need to start collecting data as soon as possible as I am conscious of the time left to do so. Any help would be much appreciated.
