  Technical problems with logging using google account
Posted by: Paweł Stefański - 05-13-2022, 04:09 PM - Forum: Platform Improvement - Replies (4)

Good morning.
My experiment is running, but the participants cannot log into the platform with their google account (gmail box). They report that their screen turns white, and the platform is not working. Is there any technical issue with the platform?
Kind regards.

  background audio not recording fully
Posted by: bisserai - 05-13-2022, 06:37 AM - Forum: Experimental Design - Replies (4)

Hi FF team,

I have a study in which i present pictures for 5 seconds and people have to say a sentence while i'm recording the background audio. When i listen to the recordings they are cut off - i can hear only half of my sentence, and i'm certain i finished speaking before the picture disappeared. I then tested by counting out loud until 5 so that 5 would come just around the end of picture presentation, and indeed the recordings only last until four or sometimes even three. I tried on chrome (i was using firefox before) and the same rhythm of counting this time had the picture disappear already at four (so this is also unexpected in itself, although  i know you recommend chrome and so request participants use that) and then the recording has me counting until three. 
I've already set up the background audio to last +1s to stimuli from group1 (that is the pictures)* and it still doesn't do it. Any advice? We definitely need the entirety of whatever was said during picture presentation recorded. In case you wanted to have a look at the study i've made a copy and titled it "study with audio not recording as long as specified".

Best,
bissera

* i've only done it for one of my blocks, to test, the practice block, which only has a few trials.

  image in portrait orientation
Posted by: bisserai - 04-27-2022, 09:17 AM - Forum: Study Grammar & Management - Replies (3)

Hi FF team,

I have many many images as stimuli, some of which are in landscape, others in portrait orientation. Those in landscape present ok, but those in portrait are halfway cutoff. When i try to have image "width": "50%" that makes lanscape images fill half the screen ok, but portrait images now stretch from the top to the bottom of the screen. In effect this means all my lanscape images are kind of small and all the portrait ones are what would be perceived as "full size" even though they are technically 50% smaller than without the width specification. Is there any way i can address this without having to manually go through all my images and find which ones are portrait and which landscape?

Many thanks,
bissera

Looks like there is some sort of problem on the Studies page of the website today. My list of studies won't load and after a few seconds I get the popup: "DataTables warning: table id=all-experiments - Ajax error. For more information about this error, please see http://datatables.net/tn/7". Same result in all browsers I've tried.

  trial limit
Posted by: bisserai - 04-26-2022, 05:31 AM - Forum: Study Grammar & Management - Replies (3)

Hi FF team,
I'm getting an error that my blocks are exceeding the number of trials allowed. The message says i have 329 trials when only 150 are allowed, but i'm not sure how this is calculated, because i thought i had only 36 trials per block...? I assume this has to do with the following piece of code, as 36 trials times 9 trial templates per trial is 324 (and then some additional cover and end trials i guess). The reason why i have so many "BS" templates is because when i was using durations of stimuli vs trials to get a blank screen this was messing with the trials proceeding properly and so adding a blank screen in between instead worked much better.

Code:
"BL1": {
          "trial_templates": ["BS","Vprime1","BS", "prime1","BS", "Vtarget1","BS", "target1", "catch"],
          "pattern": {"order": "alternate_random"},
          "fetching_point": true,
          "cover_trials": ["fixation"],
          "end_trials": ["break"]
        },
The issue is this means i'll have to more than half the amount of actual trials i have per block, which i really would rather not do and so i was wondering if this trial limit is something that can potentially be increased? 

Thanks,
bissera

  csv stimulus definitions
Posted by: bisserai - 04-25-2022, 08:19 AM - Forum: Study Grammar & Management - Replies (2)

Hi FF team,

I'm trying to upload the stimulus definitions for my study with a csv batch upload, but i've been waiting for more than 20 minutes and it still hasn't uploaded. I tried using a different browser - same thing. I checked the crash course and couldn't find any limitations i should be respecting (like with the zip stimuli batch upload for example). Any idea what the problem might be?

Best,
bissera


Hi FF team,

I've now isolated the issue to a few rows with very texty stimuli definitions (i've managed to upload everything else). I've tried using the exact same csv file that i downloaded from the builder (i always do that in case of an error) and it doesn't want to re-upload. Any ideas?

Best,
bissera

  Is there a way to have a speaker icon (audio stimuli)?
Posted by: yilmazdozlu@email.arizona.edu - 04-23-2022, 10:41 PM - Forum: Study Grammar & Management - Replies (3)

Hi Everyone,
I hope everyone is well! I have a specific question about audio stimuli. Is there any way to add a speaker icon to the audio stimuli as in the picture while the audio stimulus is playing?
 The default audio stimulus has a speaker icon. Nevertheless, it gives a control panel for the participant. There, a participant pauses and runs the stimuli. We do not want these, participants to have control over the stimulus as every participant should be receiving the same audio stimulus. We cannot know if they have control over the stimulus such as pausing and running it again.
Is there a way only to have a speaker icon on the screen? I cannot find a way to code it in the grammar reference. Without the icon, participants are receiving a blank white screen. It seems litte surprising and confusing. It is not an important problem, but if there is a way to avoid it, we would really appreciate it.
Thank you very much for your time and consideration!
Best,
Dogukan

  Multiple participant group selection window
Posted by: HF2021 - 04-18-2022, 08:08 PM - Forum: Platform Improvement - Replies (1)

Hello, Our program uses 4 participant groups.  Previously when we ran the preview option we would be asked to select which group (A through D) we would like to select.  Currently, when running the preview option, a blank tab/screen appears.  One would have to click on the prior tab to see the group selection option.  This may be very minor but it could be helpful if the group selection window would be the active screen when the preview button is pressed so that one does not miss it. Thanks!

  multi_select functionality + follow_up_response not working
Posted by: stellestrellaj - 04-14-2022, 10:36 AM - Forum: Experimental Design - Replies (1)

Hi,

I tried using the multi_select functionality in choice response type and also include the "other" option, with the possibility for participants to type in their own answer. When used separately, both functions work fine but they don't seem to work together. The follow_up_response thing no longer appears. Could you please help me on that?

Thank you for your help!
Best,
Stella

  carryover responses used more than once elicit errors
Posted by: stellestrellaj - 04-14-2022, 10:32 AM - Forum: Experimental Design - Replies (2)

Hi,

I have another issue regarding the carryover response functionality. I would like to use one carryover response as the next stimulus more than once because I want my participants to evaluate their response on more than one question. But I seem to run into errors when I do that. Could you please look into it?

    "type": "basic",
    "stimuli": [
      {"which": ["1a", "%r:TestingBlockA|main_absurd_1|text_response",

    ],

    "stimulus_pattern": {"order": "random"},

Thank you in advance!
