I'm working on a forced choice experiment, where participants are presented with a sentence including a pronoun and then choose which of two names they think the pronoun referred to. That all works with my current code. However, I also want to follow some of the trials with a comprehension question (also a forced choice response) after participants have made their response. The problem I'm having is that the comprehension questions have to occur after specific items. I tried to use catch-trials, but that doesn't seem like the right approach, given that each comprehension questions can only follow one specific trial.  
I also tried to set up as a separate trial template containing the trials to be followed by comprehension questions plus the comprehension questions themselves. By keeping the stimulus_pattern in a fixed order, I can make sure the appropriate comprehension question follows its intended stimulus + response. But then I could not figure our how to create a block consisting of N regular trials followed by exactly two of these separate trials, i.e.  1) a stimulus followed by its forced choice response, followed by 2) a comprehension question asking about something in the preceding stimulus sentence, followed by a forced choice response).
Does anyone know a way to do this?

Hi there! I am wondering which time zone FF adopts in recording and presenting the start and completion time. Thank you!

Hi administrators and directors!
I'm setting up a study on FF about bilingual perception, and my PI and I don't want English to show up in the experiment so I changed the content of the "choice" stimuli into Mandarin, but I can't find a way to change the content that's below the choices (e.g. "Press J" or "Press F"). I was wondering if there's a way to simply not show it since the participants will be asked to put there fingers on top of the keys before every ACF block starts.
Thank you!

I am having a hard time being able to launch the mouse tracking sample study that is under the tutorial. I wanted to know if that is currently the intention or if there may be a problem with either my browser or how I am accessing it. 

More specifics: 
- Under "Tutorial: Mouse-tracking Study Example", when I click on where it says "Click here to see a finished version" it takes me to the home screen of the study displaying the option to read the consent form. 
- When I click the [2. Participate] button it doesn't initiate the study. 

Thanks! 

Taking research online presents challenges. In the lab we know participants are using a mouse and headphones for our audio + mouse tracking paradigm, but online how do we know? We have them agree at the beginning to use these things, but at the end we ask how they took the study and half of them did not use a mouse. So, we do not give them credit for the study. Here is the problem: we have to see their answers to determine if they get credit. Our human subjects pool wants us to award credit within 24 hours. Right now I can't see the responses until the FindingFive session is over, right? So, what do I do. I feel stuck. I can't open a new session every day. I need to open a session once a week and have it run for a week to collect participants. But I also need to award credit to participants for taking the study within 24 hours, but I can't do that if I can't see their responses. Am I missing something that would allow me to see individual responses while the session is open? If not, then, as a researcher, I feel this is a major flaw in the platform that should be addressed as soon as possible. I hope I am just missing something. Thanks.

Hi! Is there a way to put a link into my FindingFive study so that participants just need to click it to go into a new window (ex. if they need to take a survey in Qualtrics)?

Paying Participants Made Easier

Together with building a participant pool, we have now also opened our payment system for a public beta test! As a researcher, you can now pay participants directly on FindingFive, without having to arrange your own payments. We charge a low flat fee of 15%, and participants will get paid the very next day. Read our blog post here to learn more.

I've noticed some typos in the API and the tutorials and thought you might want to know  I thought I could start listing them here and then other users can add to this if they find them too.
In tutorial https://news.findingfive.com/2019/05/29/...of-trials/
In 'Adjust the time between trials (inter-trial intervals)', in the final line, you write: By setting the delay to 2, each trial will start with 2 trials of a blank screen
But I think you mean: By setting the delay to 2, each trial will start with 2 seconds of a blank screen

With what browsers are FF experiments compatible?

A new feature has been added to the “stimulus_pattern” property in trial templates! The new “limit” feature allows researchers to sample a subsection of their stimuli listed in a trial template. 

A common implementation of the feature is to set “stimulus_pattern”: {“order”: “random”, “limit”: K} so that K (where K is an integer) stimuli randomly sampled from the trial template are presented to the participant. This setup is useful for researchers running large numbers of participants who want to show a random sample of stimuli to each participant. 

“limit” can be combined with other stimulus pattern orders, as well. Read more in our grammar reference here: https://help.findingfive.com/api/trial-t...s-patterns Questions? Reply in this thread and we will answer!
