Is there a way to disable the play/pause key on the keyboard for video stimuli. I'm trying to avoid that my participants pause the video.
I have auto-play enabled and there are no clickable buttons visible. But pressing the play/pause button on the keyboard still pauses the video.

I was running through my experiment and when I got to trial 76 (my trials are hard coded, not randomized) I got an error that "The file 205_frog_shove_monkey.mp3 is either missing or in an incorrect format. Please fix the problem and preview again."
I checked and saw that that file did indeed exist; but just for kicks, I decided to upload a new file (205_frog_shove_monkey_copy.mp3) and updated the audio stimuli for trials 76 to reflect the new filename in "content".
I ran the experiment again, but this time I got the error "The file 205_frog_shove_monkey_copy.mp3 is either missing or in an incorrect format. Please fix the problem and preview again."

So the "missing file" did not seem to be the problem.
Next, I went into Procedure and deleted trials 1-74 from the experimental block to see if I could get trial 76 to play at all.
I ran the experiment again, and trial 76 played perfectly, no error message.
So why would there be an error message when I started with trial 1 and went to 76, but not when I started from trial 75?
Next, I put back trials 1-74 so the block was complete again. Now I wondered, could this have something to do, not with the fact that there's something wrong with trial 76, but there is something buggy going on when this block reaches the 76th trial position in the block.
To test this, I deleted just trial 76 from the block, so now the trials would proceed from 1-75 and then 77. My hypothesis was that if there is something wrong with the 76th position, I would get an error message about trial 77's audio file. . . .and that's exactly what happened.
Any idea what's going on?

Is there any way of adding metadata columns to results?
For instance, I am using audio stimuli of sentences that are either "active" or "passive" syntactic voice. I tried to do this by coding "voice":"active" my active audio stimuli; and coding "voice":"passive" in my passive audio stimuli. Although this coding was accepted as grammatical in the stimuli section, none of this information shows up in the results.
I would also like to include other information about the stimuli as well -- is there any way of doing this? (I know that as long as trials are uniquely identified I could just join my results file with a separate metadata file in R, but this seems like an extra step and an extra opportunity to introduce errors!)

Dear Researchers,

Thanks to a timely report from the LEAP lab at University of Arizona, we have discovered a new bug in the latest version of Google Chrome (v.92) that has impacted some of FindingFive's functionalities. Studies featuring many audio and video stimuli, including audio recordings that result from the audio responses, may become stuck at certain point, with an error message from FindingFive warning about missing stimulus file or incorrect format. Since this is a browser-level bug, your currently active sessions may be affected as well.

The cause
This is a new bug introduced by Google. Google is already working on a fix (https://bugs.chromium.org/p/chromium/iss...144736#c27).

Actions on FindingFive's end
We are also working to identify a workaround. However, since this is a browser-level bug, a fix might not be trivial. We will update everyone as soon as we have more insights into this issue.

What you can do
If your study features many audio and video stimuli, or use audio recording responses, please preview them immediately to see if you are impacted. If so, you can ask participants to use Firefox instead of Google Chrome to complete your study until either Google or FindingFive implements a fix.

Thanks for your patience and understanding!

I've been slowly building my study today, and after adding each bit of code, I've been testing and everything's been fine.
Then I added quite a bit of new code, and tried running the study. I got the error message: Your study contains coding errors that we cannot automatically detect yet. Please refer to the Study Grammar Reference for help.
So, I took out all of the new code I had added and tried to run again, thinking it should work since this is the same code I started with. Instead, I got the error: Your study contains coding errors that we cannot automatically detect yet. Please refer to the Study Grammar Reference for help.
So I looked at the FAQ #4 -- Syntax Error post. I highlighted all of my text in both trial templates and Procedure and hit tab -- looks good, but still get the error.
So I also C&P'd both trial templates and procedure into an online JSON validator -- it is valid JSON.
I am at my wits end! Two hours ago, this code worked fine -- now I can't run it and get the same syntax error: Your study contains coding errors that we cannot automatically detect yet. Please refer to the Study Grammar Reference for help 
even though this is the same code I ran earlier. 
What else can I try?

Dear Researchers,

We are happy to announce a minor feature addition to FindingFive's study grammar: it is now possible to set "barrier" on text and image stimuli! 

What's Barrier?
If you haven't heard of barrier and its function in building adapative experiments yet, please check out this tutorial: https://news.findingfive.com/2019/04/23/...-barriers/

A hypothetical setup: display two text stimuli in order
Imagine that you are displaying two text stimuli on the same trial, where the first text stimulus should stay on the screen for 3 seconds, and then the second stimulus will show up. 

This can already be done without this new barrier support for text stimuli, but it comes with some hassle and inflexibility. Essentially, you'll need to set a duration of 3 seconds to the first stimulus, which controls how long the first stimulus is visible, AND a delay of 3 seconds for the second stimulus, which tells the second stimulus not to show up when the first stimulus is visible. This is a little clumsy - we had to modify two stimuli to achieve this functionality. Moreover, if the duration of the first stimulus is variable across trials, this will get out of control: we would need to create many duplicate versions of the second stimulus, each with a different delay setting to accommodate the duration of the first stimulus!

Barrier solves this problem
Now with the newly introduced barrier support for text and image stimuli, this can be easily done. All you need to do is to add to the first stimulus a barrier setting in addition to the duration one, like this:

Hello! :-) 
I have a question about the "continue" button. I see on the study specification grammar website that FF will automatically determine when a trial gets a "continue" button based on whether the trial duration is set to 0sec or more. i.e a study that has a duration of more than 0 won't (necessarily) get a "continue" button, but one with no duration or defined responses will. 
In my study I have trial templates with three stimuli all of which need to have different durations. The first needs to be 2000ms, the second 1000ms, and the third 500ms. None of the stimuli can have responses or buttons/button presses because they're meant to serve the same function roughly as fixations. In blocks they're yoked together with corresponding trial templates of three critical stimuli; essentially, one trial, composed of two trial templates, would be 2000ms pause >> critical stimulus >> 1000ms pause >> critical stimulus >> 500ms pause >> critical stimulus. 
I've found that I can avoid the stimuli requiring responses or button presses when I define the trial duration. However, if I keep the trial duration, then each stimulus can't have an individual duration of its own (or it can, but it would disappear before the whole trial template moves on leaving a blank screen). I have also tried to set each individual stimulus duration to its own respective duration. However, when I go to comment out the whole trial duration, the "continue" button automatically appears again. 
I'm wondering if there is a way to keep my code so that each stimulus can appear for its respective duration time (2000ms, 1000ms, and 500ms) without defining a trial duration and without the "continue" button automatically appearing? 
Thank you so much!

Hi! I wanted to find out if it was possible to make the choice text bigger and to change their color from orange to something else?

I would like to save in the response data file the content and condition specified for each stimuli. How can I do this?


I can only see the name of the stimuli given in Finding Five.  See the attachments below:


   

   

I have recorded audio files as a part of my experiment. I am now trying to listen to the .ogg files on my computer. Some of the files can be opened by normal audio players. However, some of the files are not opening with any audio player. I get an error saying that the file type or codec is not supported. What can we do about that? Thank you!
