I have branching in my study. Roughly 5-10% of the time, during a preview or when a participant is doing the study, when either one of the branching choices is chosen, the study freezes and does not continue at all. This is fairly problematic. I suppose it is happening for other researchers as well.

I have been running 2 studies for a couple months and just started a third one. They all have a similar design. Today I received some complaints from a participant that the experiment was getting stuck on the first trial. After checking all three experiments, I found that it is happening for all of them. Was there an update that might be causing this to happen? The trial has a text stimulus and response type is RecordResponse. The text disappears from the screen after the typical duration but the trial does not move on from there. I also noticed that there is a rectangle appearing below the text now that wasn't there before. 

Hello,
I need to randomize the order of all of my stimuli.
I have 6 conditions. There are two response options, "ACCEPTABLE" and "UNACCEPTABLE".
I have randomized the order of the 6 conditions/blocks and randomized the stimuli within each block. 
However, I would like the participants to see a random order of the stimuli, from all 6 blocks. 
Im hoping that explanation makes sense! I've copied some of my code below.

In Templates:
"TestTrialsQC":{
    "type": "basic",
    "visible": "true",
    "stimuli": ["1063QC", "1064QC", "1065QC", "1066QC", "1067QC", "1068QC", "1069QC", "1070QC", "1071QC"],
    "stimulus_pattern": {"order": "random"},
    "responses": ["ACCEPTABLE", "ACCEPTABLE", "ACCEPTABLE", "ACCEPTABLE", "ACCEPTABLE", "ACCEPTABLE", "ACCEPTABLE", "ACCEPTABLE", "ACCEPTABLE"]

},
  "TestTrialsQI":{
    "type": "basic",
    "visible": "true",
    "stimuli": ["1072QI", "1073QI", "1074QI", "1075QI", "1076QI", "1077QI", "1078QI", "1079QI", "1080QI", "1081QI"],
    "stimulus_pattern": {"order": "random"},
    "responses": ["UNACCEPTABLE", "UNACCEPTABLE", "UNACCEPTABLE", "UNACCEPTABLE", "UNACCEPTABLE", "UNACCEPTABLE", "UNACCEPTABLE", "UNACCEPTABLE", "UNACCEPTABLE", "UNACCEPTABLE", "UNACCEPTABLE"] 

In Procedure:
"TestTrialsQC": {
      "trial_templates": ["TestTrialsQC"],
      "stimulus_pattern": {"order": "random"}

"block_sequence": [{"$randomize": ["PracticeBlock", "TestTrialsCC","TestTrialsCI", "TestTrialsNC", "TestTrialsNI", "TestTrialsQC","TestTrialsQC"]}]

Is there any way to query the participant's device? For example, can we play audio and automatically determine whether they used headphones or computer speakers? Or can we automatically determine whether they used a touchpad, touchscreen, or external mouse to respond?

Hi!
I'm testing a study aimed at native Spanish speakers. I noted that the language of the browser determines the language of the instructions; however there are several misspellings in the translations.
Can I help to improve that translations for Spanish? I understand maybe is a browser translation function, but if it is possible change that error, I will be happy to help.

Hello world!
I'm creating a word association task. Participants must write a word in response to a cue word. I´m using the response option"keypress" because it is important to evaluate the first key press and the interval between each key press; however, it is laso important to me that participants can see what they write.
I tried to combine two resposes "keypress" and "text" as explainned in the tutorial Recording participant responses, but F5 ignore the "keypress" response and only record the "text".
I'm not shure that this is the best approach to solve my problem.
My current code is:
"test_trials":{
  "type": "basic",
"stimuli":["w01","w02","w03","w04","w05","w06","w07","w08","w09","w10","w11","w12","w13","w14","w15","w16","w17","w18","w19","w20","w21","w22","w23","w24","w25","w26","w27","w28","w29","w30","w31","w32","w33","w34","w35","w36","w37","w38","w39","w40","w41","w42","w43","w44","w45","w46","w47","w48"],
  "stimulus_pattern": {"order": "random"},
    "responses": [["k_resp","t_resp"]]
},

Thanks to everyone

I remember seeing an email from FindingFive late last year saying that FF has a beta version of voice activated reaction time as a kind of response for experiment. I wonder if there's an API I can refer to set up to test the voice activated reaction time in my experiment? Thank you!

I'm working on a forced choice experiment, where participants are presented with a sentence including a pronoun and then choose which of two names they think the pronoun referred to. That all works with my current code. However, I also want to follow some of the trials with a comprehension question (also a forced choice response) after participants have made their response. The problem I'm having is that the comprehension questions have to occur after specific items. I tried to use catch-trials, but that doesn't seem like the right approach, given that each comprehension questions can only follow one specific trial.  
I also tried to set up as a separate trial template containing the trials to be followed by comprehension questions plus the comprehension questions themselves. By keeping the stimulus_pattern in a fixed order, I can make sure the appropriate comprehension question follows its intended stimulus + response. But then I could not figure our how to create a block consisting of N regular trials followed by exactly two of these separate trials, i.e.  1) a stimulus followed by its forced choice response, followed by 2) a comprehension question asking about something in the preceding stimulus sentence, followed by a forced choice response).
Does anyone know a way to do this?

Hi there! I am wondering which time zone FF adopts in recording and presenting the start and completion time. Thank you!

Hi administrators and directors!
I'm setting up a study on FF about bilingual perception, and my PI and I don't want English to show up in the experiment so I changed the content of the "choice" stimuli into Mandarin, but I can't find a way to change the content that's below the choices (e.g. "Press J" or "Press F"). I was wondering if there's a way to simply not show it since the participants will be asked to put there fingers on top of the keys before every ACF block starts.
Thank you!
