  "Response received"
Posted by: [email protected] - 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 (17)

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!

  Timing out
Posted by: aczyp - 12-11-2020, 05:19 AM - Forum: Platform Improvement - Replies (2)

Hello,

the studies on FindingFive (EU-server) seem to be unavailable. The trouble started around 10 pm (Berlin/Amsterdam time) yesterday evening.

FindingFive will let me log in and out. Yesterday evening I was able to see an overview of my studies and open them, but then it timed out when I tried to look at the materials. A bit later, it wouldn't open at all. Today, it is opening again, but it won't load the overview of the studies available for participation, and neither my own study list. Resource files and help pages are available though.


Currently I have no active studies, and am collaborating on three inactive studies. So far, my collaborators have not been complaining about the same problem. I have tried logging out, logging in, restarting the browser etc., but it doesn't seem to do the trick.
Sometimes, an error message will appear:
DataTables warning: table id=all-experiments - Ajax error. For more information about this error, please see http://datatables.net/tn/7 


I would be very grateful for any recommendation, best, Anna

  language in the "continue" button
Posted by: [email protected] - 12-08-2020, 01:21 PM - Forum: Study Grammar & Management - Replies (5)

Hi,
I've noticed that the first screen one gets when running a task (informed consent, etc.) as well as the continue buttons that appear along the task, are in Spanish. How can I change them to English? I usually have two versions of each task, one in each language.
Thanks

  Retry study after dropping out
Posted by: CarsonGMR - 12-07-2020, 04:39 PM - Forum: Platform Improvement - Replies (2)

I am currently running sessions with the option to allow past participants turned off, but the option to allow past 'dropouts' to retry turned on. However, I've heard from participants that they haven't been able to retry the study. Specifically, I think participants are opening the study on one device, switching to another device, and attempting to reopen.
It may be that participants simply aren't actually closing the page on the first device, which would be a whole other issue. However, before starting to investigate those options, I thought I'd check if there are other common issues with implementing the retry options or any suggestions for things to check here?
Thanks!

  Internet speed/bandwidth limiting
Posted by: amiefairs - 12-07-2020, 07:45 AM - Forum: Platform Improvement - No Replies

Hi FindingFive devs - an idea for a future feature may be to introduce an internet speed check/limit, such that participants with a download (or upload) speed lower than a certain value cannot take part in a specific study. This would be a value that researchers could set, and the bandwidth of a participant would be checked before they begin the study, and could screen them out. I don't know if this is hard to implement, but for myself I know I would find it useful. Just a potential idea.
Thanks for all the great work!

  Multiple sessions open
Posted by: jwright8 - 12-01-2020, 02:17 PM - Forum: Platform Improvement - Replies (2)

It seems that it is not possible to have multiple sessions open at the same time. If that is possible, how do we do it? If it is not possible, I would like to recommend that it be changed so that it is possible. Many people are interested in my experiment and want to check it out for learning or seeing how it works. So, I would like to leave a public facing session open for those people and then run my controlled experiment in another session. It would be nice to be able to do that.

  stimuli of pictures with a random prob sequence
Posted by: cynthiayu316 - 11-23-2020, 04:09 AM - Forum: Experimental Design - Replies (7)

Hi, I am working on designing an online experiment. There are three stimuli and the probability of winning the reward from the stimuli is fixed. But for each trial, the probability of which ice hold corresponds to which fixed probability will be randomly assigned. So is there a way when designing the experiment, I could randomly generate sequences for different prob and assign them to different stimuli? For example: for the first trial, 30% for left stimuli, 50% for the middle one, 80% for the right one. Then the next trial, 30% for middle, etc) I check the documentation but did not find a parameter that could solve the question mentioned above. I was wondering id there any way I could achieve that? Thank you!
