  Help setting up a study with a special design.
Posted by: LSydell0628 - 01-18-2021, 03:04 PM - Forum: Experimental Design - Replies (1)

Hello,

I am a journalist, most well known for my work reporting on technology and culture for National Public Radio(NPR). As part of my research for a story on cyber bullying I am working with two post-doctoral students. We all met and began our work together as part of a fellowship with the Diverse Intelligence Summer Institute ( https://www.diverseintelligencessummer.com/
 We are looking at the effect of using the voice to respond to a provocative story on social media.

We think that Finding Five is the right platform for our research. But we have some questions about capabilities on the platform and whether you might be able to help us use the platform for the study.

The basic idea of the study is to set up a page that looks a lot like Facebook with a story from a user that is designed to provoke anger and controversy. We then want to see what happens if people have to use voice to text software to respond and therefore have to hear themselves speak versus simply writing their response in text. The question is whether hearing yourself speak makes you less inclined to bully?

We also would like to add other possibilities to our control groups. For example we want to make it possible for people to record themselves using voice to text and then to hear it played back to them before they send it. Instead of simply hearing their own voice, we wonder if it’s possible for it to be read back by some kind of computer voice.  We would also like it if they could erase what they heard and re-record. Finally, we would like to enable the people who did voice to text to make any corrections by simply fixing the text itself.

I’m writing to you because I want to see whether or not we will be able to set up a system on Finding Five that would allow this? If Finding Five is not currently set up to do this would it be possible to work with someone there to create this kind of interface? Lastly I’m wondering what the costs of this study would be?

We look forward to hearing from you. 

Kind Regards,

  Centering crosshair when played multiple times
Posted by: aweson - 01-08-2021, 12:10 AM - Forum: Study Grammar & Management - Replies (4)

Hi, I've been working on designing a study where a sound is played, a crosshair flashes, a sound is played, a crosshair flashes, a third sound is played, and a final crosshair flashes on the screen. The participant should press F if the third sound is the same as the first one, and they should press J if the third sound is the same as the second one. 
The issue that I'm having is that I want the crosshair to appear in the center of the screen each time, but instead it has been appearing from left to right even after the crosshair disappears. 

This is an example of my current setup:
Trial template: 
"MainTrialStimuliA":{
  "type": "AFC",
  "auto_advance": true,
  "delay": 0.1,
    "stimuli":  [["audioStim1", "crosshair", "audioStim2", "crosshair", "audioStim1", "crosshair2"]],
  "responses": [["ResponseF"]]
},

audioStmi1 (audioStim2 has the same setup):
{
  "type": "audio",
  "content": "dent retr 1 vcls vcng 0 aCa.mp3",
  "visible": false,
  "delay": 1
}


crosshair:
{
  "type": "text",
  "content": "+",
  "alignment": "center",
  "duration": 1,
  "size": "24px",
  "delay": 1
}

crosshair2:
{
  "type": "text",
  "content": "x",
  "alignment": "center",
  "duration": 1,
  "size": "24px",
  "delay": 1
}

  possible to branch based on combination of two Responses?
Posted by: screel@ucsd.edu - 01-06-2021, 04:09 PM - Forum: Study Grammar & Management - Replies (7)

I'm trying to set up a study in which participants must 'pass' the training trials with a criterion accuracy score to continue. I'd like to branch to repeat training iff the initial training block score is too low. I get that I can use the "iterations": feature, which is cool. But the problem is that I need to compute the score based not on one response but based on two responses. This is necessary because, half the time, the answer "same" is correct and half the time "different" is correct, and the total score is a combination of the two.
Am I missing a simple solution here, such as coding same and different as a single response somehow?  Huh Or combining two different triggers? Thanks for any suggestions!

  Multiple prerequisites
Posted by: rmp - 01-05-2021, 05:39 PM - Forum: Study Grammar & Management - Replies (2)

Hi, I am currently trying to launch a study where only people who have participated in one of two prior studies may be eligible. As I understand it, selecting multiple studies as prerequisites in "Step 4: Prerequisites and anti-prerequisites" means participants have to have completed both studies selected. Is there a similar way to set the prerequisite such that participants are eligible if they have completed either/any one of the studies selected?

If not, my workaround was to manually enter the worker IDs of eligible participants in Step 4.1 under "Allow only the following participants in this session." But, I just wanted to check if there was an easier way I may be missing before doing this. [Also, as a note, the timing of this session is important, so I can't launch two sessions on two different days/times with each of the two different prerequisites]

  Perception study/Phonology
Posted by: mkostantinov@ufl.edu - 01-05-2021, 12:06 PM - Forum: Experimental Design - Replies (6)

I am new using FindingFive and I am practicing how to use this platform by setting up an experiment for a perception study I need to conduct, and I was wondering if you happen to have more detail tutorials (e.g., videos) on how to set it up. I believe that the syntax I am using has an error. When I try to run it, it says line 183 has an error, but I don’t see this line numbered anywhere. I wonder if the error might be coming from a discrepancy between the trial templates/procedure and/or responses? I also uploaded the audio files in wav. format. In the “stimuli” grammar reference guidelines for “audio”, it does not specify other type of audio formats. I tried also to upload them in mp3 files, but it would not allow me.
So, if you have more specific guidelines for a phonology study that includes an identification and discrimination tasks, I would appreciate it.
Looking forward to any suggestions!
Andreína.

  Audio files batch uploading
Posted by: Sousou - 12-30-2020, 03:20 PM - Forum: Experimental Design - Replies (2)

Hello, 
My experiment uses audio stimuli. I want to know if there is a way to upload the stimuli at once and not have to do it one by one. I added the stimuli definitions via CSV batch uploading. However, I still have to upload the audio files manually one by one, which is tedious. The CSV included the the name of the files and the content as "filename.mp3" but when uploaded, the files are all red and ask that I upload the files. If this shouldn't be the case, I wonder why I am having this issue. 
Thanks,
Sousou

  "Response received"
Posted by: alejandraraisman8@gmail.com - 12-21-2020, 01:15 PM - Forum: Study Grammar & Management - Replies (2)

Hi,
I have designed a task that requieres participants to "say" a word out loud. Everytime they do that, a "response received" little blue sign appears at the top of the screen. It's really distracting. How can I avoid that from happening?
Thank you!

  Sequence of images as stimuli + formatting
Posted by: jchough1 - 12-17-2020, 12:56 AM - Forum: Experimental Design - Replies (3)

Hello!  I am continuing my work on my same experiment, which involves presenting sequences of images with strictly timed settings and formats (see my previous thread for more context).
I am wondering how to present stimuli in this way: 
1. Maintain a single image at the top center of the screen. 
2. Flash several images consecutively below and to the left (or right) of this fixed image without requiring any prompting from the participant.  
3. Close the entire stimuli without participant interaction.  
I was unable to figure out how to maintain the fixed image throughout the entire stimulus (this solution would be extremely helpful for other parts of the experiment as well!).  However, I was able to flash the stimuli using the "duration" category, but the issue lies with the fact that it forces a "continue" button to progress, even after the stimulus duration has elapsed (the button waits on a blank screen).  
Please let me know what you come up with.  Thank you for your help!

  Trials displaying longer than their set time?
Posted by: amiefairs - 12-14-2020, 10:59 AM - Forum: Study Grammar & Management - Replies (5)

Hi FindingFive, I have a study I am coding up but have noticed when I preview the exp that some of the stimuli stay on screen longer than they are supposed to. I have fairly rapid presentation of words and blank screens which alternate, and after a stream of words/blank screens, there is a question mark and an exclamation mark. The words should be on screen for 0.7 seconds and the blank screens display for 0.3 seconds, and then the question mark for 0.5 seconds and the exclamation mark for 1.2 seconds. As an example:
Blank screen -> words -> blank screen -> words -> blank screen -> words -> question mark -> exclamation mark
However, the final words screen (the third instance above) is always displayed for longer than 0.7 seconds and the exclamation mark is also displayed for longer than 1.2 seconds.
Originally I had background audio recordings on the question mark and exclamation mark trials, but whether I record a response or not makes no difference. Bizarrely, even though I have removed the responses, on these longer trials in the preview the little green 'response recorded' box comes up at the top of the screen.
I have the timings set at the trial level with no timings set at the stimulus level, and I originally had submission_point=FALSE set on all trials except the exclamation mark (assuming then I might have longer responses on the exclamation mark only). I've since removed submission point but this now makes each trial take longer (which doesn't surprise me) but I still have these extended trial lengths on some trials even if it is set to FALSE.
Do you know why the timings sometimes aren't respected?

  Audio Skipping in Simultaneous Audio Presentation and Recording
Posted by: CarsonGMR - 12-11-2020, 04:24 PM - Forum: Platform Improvement - Replies (3)

I've been collecting data in a study that simultaneously collects audio using

Code:
background_audio
and presents audio using
Code:
audio
.  Things seem to be working well overall, but I happened to notice that for at least one participant, the audio stimulus seems to skip in several trials -- in this case the stimulus is also picked up in the audio recording, and I noticed that small sections of the audio stimulus repeated.
My best guess is that this is an issue with doing simultaneous audio output and input that is outside the scope of the SSG, but thought I'd check if anyone else has noticed audio skipping in other studies?
Before diving in to deep, I thought I'd also just check if there are known issues with using audio (which I think uses a standard js audio object) and the background_audio recorder (which I think is implemented here)?
Thanks FF team for putting together this great system!! I've been incredibly impressed with how flexible it has been!
