I am building an experiment with stimuli set with definitions that look like this:

Dear FF team,

I'm setting up a norming study for which i would like to have participants listen to an audio stimulus (e.g. a1, a2, a3...), then be presented with two text options on screen (a1_1 vs a1_2, a2_1 vs a2_2...) and use the keyboard only to select whether they choose the left option or the right option. I'd like to record that they chose a1_1 or a1_2 regardless of where on the screen they were presented. At first i had my audio and text options on different trials and tried using a choice type response with key_mapping "L" and "R" and a key_only response, but that gave me L and R buttons, as well as additional text instructions telling ppts to make a choice. Now i have the audio and the text options on the same trial, however i get a continue button and the fixation cross that's supposed to be in the middle is shifted left. I thought i could use "location" but that's only for responses, and my text options are stimuli - i don't want to make a different response for each audio stimulus. Ideally i'd like to have my fixation cross centered (location 5) and once the audio is done (this bit is fine, the text options appear after the audio) have the text options appear in locations 1 and 3.

Thanks a lot for your help!

Hi Ting, 

I hope you're well! 

I have a question about providing participants with feedback on their responses, as well as with some demographic questions. 
I am using keypresses for responses to my stimuli, so participants will see the stimuli and have to press either the 'F' or 'J' keys. However, I'd like to add in feedback, so if they press the 'F' key when they should have pressed the 'J' key they will get feedback (maybe something like 'error' and a reminder of S-R keypress mappings). With choice responses, participants can get said response feedback, but the two keypress choices are displayed at the bottom of the screen. I'd like to avoid this if possible. Do you have any advice on how to give response feedback while still using keypress responses? 

I've also been working on adding in my demographic questions, but I've hit a bit of a roadblock. I've defined my stimuli and the associated responses, built the trials in "Trial Templates", and built the demographic trials into "Procedure", including the trial sequence. However, no matter the type of response defined, the "continue" button shows up. For example, I have a question asking about gender identity, and the response is a choice response as follows: 
{
  "type": "choice",
  "choices": [
    "female",
    "male",
    "non-binary",
    "prefer not to answer"
  ],
  "key_mapping": [
    "F",
    "J"
  ],
  "target": "YES"
}

The whole code is: 
"DemographicGender": {
  "type": "basic",
  "stimuli": ["DemographicGender"],
  "response": ["DemographicGenderResponse"]

When I run the study, instead of any of the available choices popping up, only the "continue" button is displayed. So, the question will ask "what is your gender identity" and instead of the choice responses, only "continue" will display. This is the same for text box responses. (And actually right now the choices that should be displayed in the example above are "YES", "NO" because I was testing this out with previous response code that has run fine in previous studies). 

Thank you so much!

As I'm extracting reaction time for one of my experiments run on FF, I have the following question about the onset detection feature of audio responses. If I have the setting of "delay": 0.3 for the test trials in my trial template, does the detected reaction time include the "0.3"? In other words, is the reaction time calculated from only the start of my stimuli till the point at which the participant first starts to speak, or is it calculated from the start of the trial till the point at which the participant first starts to speak?

Thank you so much!

Dear Researchers,

The FindingFive Study Grammar has been updated to include the following new features, bugfixes, and other minor changes.

New Features

• It is now possible to assign the key corresponding to the "continue" button to a key other than the space bar, or just disable it altogether. https://help.findingfive.com/api/trial-t...html#basic
  

• No bug fixes in this update
  

• If a study features audio recording or other actions that require microphone access, the way that participants are asked to share their microphone access is now more intuitive to participants. 
  
• If a participant uses a keyboard with media control keys like "Play" and "Stop", pressing those keys will no longer have an effect on audio and video stimuli.
  

Greetings,

The study is about English grammar and the treatment consists of 99 fill-in-the-blank sentences. Half of the sentences are untimed, i.e. participants move at their own pace but the other half are timed meaning that each sentence is shown for 27 seconds and it automatically moves to the next sentence which is untimed. All the sentences must show feedback but feedback for the timed sentences must be displayed for 3 seconds before moving automatically to the next sentence which is untimed.

Here are my questions below:

1. How do I underline text stimuli? The stimuli are underlined "stimuli bank" but it doesn't show up in the preview.
   
2. How do I display some individual sentences for exactly 27 seconds as well as the feedback for each of these timed sentences? In other words, sentence1 is shown for 27 seconds followed automatically by the feedback for 3 seconds before it moves on automatically to sentence2, along with its feedback, which are not timed.
   
3. I need to use fill-in-the-blank responses but how do I display "correct" and "incorrect, the correct answer is..." feedback for each sentence? How would I go about displaying the feedback for some of the sentences for exactly 3 seconds before it automatically moves on to the next sentence?
   
4. How do I upload several images all at once? 
   
5. How do I place three sentences on their on their individual line instead of having them follow each other like sentences in a paragraph? I know how to create paragraphs but I just some sentences to be next to each other on their own line. 
   
6. I have two experimental groups and one control group. Do I need to create three separate experiments?
   

Is it possible to mute video stimuli in Finding Five?

I am working on a comprehension experiment where participants see video recorded sentences and choose their response to the sentence with a button press. I would like to keep track of whether the response they choose is on the left of right side of the screen. 
Right now, I have button location randomized automatically. I can of course undo that and instead create pseudo randomization in my stimulus list by hand. But before I go that route, I thought I'd ask if there is a way keep the randomization and obtain information about response choice locations in the output?
Thanks!

Is there a way to do this? I find that when an instruction follows a self-paced reading trials (where participants have been clicking the spacebar rapidly), it risks being skipped unintentionally. So for certain trials, I would like to require the a mouse click to advance to the next trial.

Has anyone experienced long video stimuli crashing? I have one video that keeps crashing at 5:42. It seems to be a feature of the file somehow, because the same thing happens in an experiment where the only trial is the video. I have tried setting a fixed duration and leaving duration unspecified, and it doesn't seem to make a difference. The video plays without issues outside of the experiment (i.e. when i play it from Resource files). I have another video of the same duration that plays just fine in the same experiment - both videos are .mp4. Any advice is appreciated!
