Response options before stimuli appears |

Hi All,
I am setting up a 4AFC study with four images as choices for the response and the stimuli is an audio file corresponding to one of the four images. I would like the images to appear on the screen before the audio plays. Is it possible to present the response choices before the stimuli of the trial?
Thank you!

branching changes |

About 8-12 months ago I ran several studies that used branching. I need to run another condition now. The branching is no longer working. It seems things have changed that have resulted in my branching code to no longer work. Can someone help point out what needs to change now?
Here is the branching block:
"matchAFCblock": {
"trial_templates": ["MouseCheck1"],
"branching": {
"method": "match",
"triggers": [
{"trial_template": "MouseCheck1", "response": "MouseChoiceResponse1"}
],
"branches": {
"YesBranch": ["I have the right equipment"],
"NoBranch": ["I do not want to participate"]
}
}
},
"matchedYes": {
"trial_templates": ["YouClickedYes"]
},
"matchedNo": {
"trial_templates": ["YouClickedNo"]
},
Here is the block sequence:
"block_sequence": ["intro", "mouseintro", "headphoneintro",
"matchAFCblock", {
"NoBranch": ["matchedNo"],
"YesBranch": ["matchedYes",
"InstrBlock", "TrainBlock1", "TrainBlock2", "TrainBlock3", "TrainBlock4", "Test1Block", "Test2Block", "Test3Block", "OvertQuestionsBlock1", "OvertQuestionsBlock2", "OvertQuestionsBlock3", "LanguageBackgroundBlock"]
}
]
Thank you in advance for your help!

trial template with no-response and required-response trials |

Hi FF team,
I'm trying to make an experiment in which i play audios and only collect a keypress response after some of them. To that end i've set up my procedure to show the "audio", "response" and "submit" trial templates in this sequence (last one is just a blank screen where the response is submitted). "audio" just plays the audio, and then "response" i'm not sure how to set up because i want to collect a response only on some trials. Here's what i have at the moment, where "blank1" is a blank screen for 1s and bague is an image to which i want the ppt to give a keypress response:
Code: "responses1": {
"type": "basic",
"stimuli": ["blank1", "bague", "blank1", "bague", "blank1"],
"responses": ["X","key","X","key","X"],
"auto_advance": true,
//"duration": 3,
"submission_point": false
},
So i've set up two responses: "X" and "key" the former being a key response which i don't look at and the latter a key response which i've set to be "required": true. However, unless i have my trial duration set, i don't advance from the "response" to the "submit" screen even though i have the "auto_advance":true. The duration of "blank1" is 1s, and the stimulus itself appears for 1s, but then i don't proceed to submit, because there's nothing to tell it that i want to get to the next trial. That's the case even if i press a key to give a response. When i //"responses":["X","key","X","key","X"], i get a smooth running audio presentation, response time, submit time, repeat. So it's something to do with the response, but i can't figure out what. I've tried setting the duration of the response to be the same as the stimulus by using the ,"duration": "%sgroup:group2" feature, but it didn't work.
One option i see is to leave the trial duration set, but then this needs to be overriden by the response "key" which MUST be given before the exp can proceed and i'm not able to find a way to do this (i.e. it's already set to "required":true, but that doesn't do it.)
Thanks for your help!

Participant unable to enter study |

Hello!
I am currently collecting data and I had a participant reach out to me telling me that after reading the consent form and hitting the "participate" button they were taken to the bottom of the screen with no way to proceed to the study. They tried entering the study using both Firefox and Chrome. They are eligible for the study and were specifically included using the "allow only..." feature when setting up study sessions. I have not had any other participants contact me about this issue. Besides switching browsers, is there another way to go about helping this participant?
Thank you!
Grace

"credit granting" |
Posted by: sten_knutsen - 02-14-2022, 11:59 AM - Forum: Platform Improvement

Our university uses Sona Systems to manage participants. It has an "external study credit granting" feature that allows participants to be granted credit as soon as they complete an external study. On their website, Sona has instructions on how to implement this feature on many online experiment presentation platforms, but Finding Five is not listed: https://www.sona-systems.com/help/
Is there any way of implementing this feature with Finding Five?
