  Support for setting "barrier" on text and image stimuli
Posted by: Ting - 07-22-2021, 11:11 AM - Forum: New Study Grammar Features - No Replies

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:

"barrier": true,
"duration": 3

This tells FindingFive to display the first stimulus for 3 seconds, and bars all subsequent stimuli or responses from showing up until the duration is over. In other words, the barrier function allows you to avoid changing the definition of all following elements, stimulus or response, on the same trial. Overall, such a setup offers a cleaner flow and more predictable trial behavior.

Documentation page is updated
You can find the new entry on "barrier" for the text stimulus and similarly for the image stimulus.

  "continue" button and trial duration
Posted by: gdemeurisse@ufl.edu - 07-09-2021, 09:22 PM - Forum: Study Grammar & Management - Replies (10)

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!

  Change color and text size of choice buttons
Posted by: rkorpan - 07-07-2021, 01:26 PM - Forum: Study Grammar & Management - Replies (2)

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?

  Saving content and condition in the results file
Posted by: santinmike - 07-06-2021, 07:37 AM - Forum: Experimental Design - Replies (1)

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:

  Playback of recorded audio files
Posted by: jwright8 - 07-05-2021, 02:23 PM - Forum: Platform Improvement - Replies (1)

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!

  collaboration from different countries
Posted by: aczyp - 07-05-2021, 08:23 AM - Forum: Study Grammar & Management - Replies (2)

Hello FindingFive,
I am trying to collaborate with someone who is currently based in China, while I am based in the EU and work on the EU server. My (intended) collaborator seems to be having trouble accessing FindingFive, setting up an account, and generally using the platform.
We are wondering what the trouble may be. Should they be logging in to another non-EU server? Is FindingFive simply not accessible from China? If yes, would there be any kind of workaround, short of collaborating via screenshare from my account only? 
Any help will be much appreciated. Thank you, and best wishes, Anna

  Access to Qualtrics while participating in FF study
Posted by: Hyeonah - 07-01-2021, 08:32 PM - Forum: Experimental Design - Replies (2)

I wonder whether it is possible for participants to access the Qualtrics survey while they participate in the FF study.
Specifically, after reading the text in the FF, participants can see a screen where the Qualtrics link appears so if they click it, they might be prompted to move on to the Qualtrics survey.
Would this design be possible? 
Thank you!

  Link FF experiement to Prolific
Posted by: haoyunzhang89@gmail.com - 06-23-2021, 03:32 PM - Forum: Experimental Design - Replies (3)

Has anyone integrated their FF experiment to Prolific before? I wonder if, 1) Participants' prolific ID could be carried over to findingfive so they don't have to put in a participant ID, and 2) If participants have to create a findingfive account if they are from Prolific.

  Auto-advance and feedback for keypress
Posted by: haoyunzhang89@gmail.com - 06-21-2021, 05:52 PM - Forum: Study Grammar & Management - Replies (4)

Dear FF team,
For the keypress type, could it be auto-advanced? That is, whenever participants make a response, the current trial will end and advance to the next trial?
A second question, could correct responses/targets be set for keypress type so participants can get a feedback about right or wrong after each trial?

  Templates for common paradigms
Posted by: haoyunzhang89@gmail.com - 06-21-2021, 01:12 PM - Forum: Experimental Design - Replies (1)

Dear FindingFive Community,
I wonder if there are some templates that can be used for common cognitive psychology paradigms such as Stroop, Digit Span, etc. I believe it would be a great benefit for the community. Smile
