I would like to present videos in different length sequences. That is, on one trial, participants see one video before they respond. In another, they see 2 or 3 or 4 before responding. I tried grouping the vide stimuli within the trial template (e.g., [[vid 1, vid 2], [vid 3, vid 4, vid 5]], but then the first video stays visible when the next starts to play, which I would like to avoid. What other ways are there of achieving this?

Hello,
I am trying to show image stimuli(i.e. a big scene image) that are superimposed by another image(i.e. smaller face image) in each trial.
Since I am planning to randomize scene-face pairs, making superimposed images in advance and uploading those images may not be available.

Could you suggest any useful grammar or method for this?

Thanks,

An experiment that was working 5 months ago (when last I tried to run it) is now freezing at the first block of trials. The instruction page is presented correctly, but when it moves on to the section when stimulus images are to be presented, nothing happens. 

This study was working perfectly fine 5 months ago. Any ideas what might have changed?

Hello!

I am running into an error on Finding Five where it tells me that unsuccessful branching occurred with an error message on the screen right after I finish the headphone check. I have blocks before that load with no issues but once I try to advance after the end of the initial headphone check I get the error message, regardless of whether I branch into eligible or not eligible. Any ideas as to what's causing this or how to fix it?    

Thank you!

I've been trying to run some sessions on MTurk and I've gotten some participants saying that they get an error when they try to load the study "There is no content to display at this URL. In some cases you may see this page because your cookies are too restrictive"
I got a few participants to complete the study, so it's working for some people, but it also gave me the error in Sandbox mode (see attached screenshot).
Does anyone know what is going on or how to fix it?

Dear Ting!
I am not sure whether you have read my last message, so I am writing one more time. My research is aready running (4 pieces), but some of the participants report the problem with creating an account on the platform. Firstly they receive the error message. They continue proceeding and manage to input the data concerning the name and password, but when they try to log in to the platform for the first time they encounter the message on "invalid recaptach data". I have advised to change the web browser or use other email adress, but it still does not work.
Please find attached three jpeg files with the screenshots of the problem. I have erased the data concerning login and password, but I am quite sure they have been entered correctly by the participants.
I would be grateful for your assistance in that matter.
Yours sincerely.

Hi!

I wonder if FF allows us to randomly select from a pool of sentences and administer them to each subject?

For example, for Block A & Block B, we have 36 items in total, and we'd like the program to randomly administer 12 sentences (6 go to Block A, 6 go to Block B, and we don't want repetition within these randomly chosen 12 sentences). 

Please let me know if any of this doesn't make sense to you!

Thank you so much,
Yuting

Hi Ting,

For my study, participants first listen to an audio sentence, at the offset of the sentence,  a visual target will appear on the screen, participants need to press a key to indicate if the visual target and the final word of the heard audio sentence is a match or mismatch.

When I looked at the data, I found that the actual RTs should equal to "trial_duration" minus the length of the audio file but not the values in the column "response_rt". Is there a way to directly log the actual RTs that I want onto the FF results spreadsheet? 

Thank you!

Hello All. 
I am working on a new study and I need to change the size, or colour, or make bold only a one word/phrase of the response sentence. For example, in the following response: 'to beat around the bush' , I would like the word 'bush' to be bold, and the other words to have 'regular' font. As an alternative, it can have different colour or size. I know the program allows a researcher to adjust the size of the whole response, but is it possible to change the part of it to be bold? (or change its colour or?).
If yes, how should I create a particular command? 
Thank you in advance! 
Kind regards
Paweł

Hello!

I wonder how I could counterbalance the order of "test_noise" and "test_accent" for a between-subject design? Subjects should be randomly assigned to Group 1, 2, or 3, but they will complete both noise test and accent test, and I wish to counterbalance the order of these 2 test blocks. Here's my code:


"block_sequence": [
                    "General_Instruction", "Subject_ID", "Sound_check",
                    {"Group1":["c_practice", "c_exposure_1", "c_exposure_2", "c_exposure_3", "c_test_noise", "c_test_accent", "c_baseline"],
                    "Group2":["n_practice", "n_exposure_1", "n_exposure_2", "n_exposure_3", "n_test_noise", "n_test_accent", "n_baseline"],
                    "Group3":["a_practice", "a_exposure_1", "a_exposure_2", "a_exposure_3", "a_test_noise", "a_test_accent", "a_baseline"]}
                    "Survey"] 


Thanks!
