I'm trying to launch my study. When I click on Sessions, I see Active and Finished but I don't see New Session. If I click on Active and Finished, nothing is there. How do I launch my study?

  judgments of learning
Posted by: kolenorberg - 08-26-2023, 10:35 AM - Forum: Study Grammar & Management - Replies (2)

I need to have participants make judgments of learning (JOLs) after they answer each question. Ideally, they would answer a question and on the next screen they would get a JOL which asks them about their confidence in their answer on the previous screen. My question blocks look like the ones below. Basically, they see the passage above the question, then the question below the passage, and then the response choices. I would like to have a JOL occur after every question, but I still need to keep the questions in a random order.  Is there a way to accomplish what I want without setting up a question block for every question?

This is my current question block that doesn't include the JOLs between questions:

    "Acupuncture_e_questions": {
  "type" : "basic",
  "stimuli": [{"which":["Acupuncture-Easy-Manipulation","A_E_C_1"],"location":[2,8]},
  "duration": 60,
  "countdown_visible": true,
  "stimulus_pattern": {"order": "random"}

This would do what I want, but I'm really trying to avoid coding this for 135 questions (3 conditions, each with 3 sets of 15 questions):

"Acupuncture_A_E_C_1_question": {
  "type" : "basic",
  "stimuli": [{"which":["Acupuncture-Easy-Manipulation","A_E_C_1"],"location":[2,8]},
  "duration": 60,
  "countdown_visible": true

  randomizing blocks and response choice display
Posted by: kolenorberg - 08-21-2023, 02:59 PM - Forum: Study Grammar & Management - Replies (4)

I have a study with three passages which fall in one of 4 conditions. I want participants to see each passage in one of the conditions but I want whether or not they receive all conditions across passages to vary randomly. Something like the below code which doesn't seem to work. How can I accomplish something like this? Specifying a condition for all possible combinations here is a little unwieldy and wouldn't replicate a prior experiment well. 

"block_sequence": [{"$randomize":[
        "A_C": ["A_full_control"],
        "A_E": ["A_only_easy"],
        "A_H": ["A_only_hard"],
        "A_HE": ["A_full_manip"]
        "C_C": ["C_full_control"],
        "C_E": ["C_only_easy"],
        "C_H": ["C_only_hard"],
        "C_HE": ["C_full_manip"]
        "D_C": ["D_full_control"],
        "D_E": ["D_only_easy"],
        "D_H": ["D_only_hard"],
        "D_HE": ["D_full_manip"]

The other issue I'm having is more minor, but I'd like to have a passage and a comprehension question with answer choices on the same page. I want the passage below the question but that means I need to get the choice to appear between the two stimuli. Is there a way to do that? 
Thank you

  2023 Fall Study Grammar Update
Posted by: Ting - 08-12-2023, 10:28 AM - Forum: New Study Grammar Features - No Replies

Dear Researchers,

The 2023 Fall Study Grammar Update is almost here! This update contains quite a few new features and improvements that we are really excited about!

Please note:

  1. Do you use the Keypress Response type? If so, please pay special attention to item #1, as it may affect any scripts you have for processing reaction time data.
  2. As always, you MUST preview your study in full to update to the latest grammar version in order to use these features.

FindingFive servers (US and EU, in their respective local times) will be updated on the early morning of August 14, 2023 to include the following changes:

1. Reaction time data for Keypress Responses now calculated from previous keypress!

Previously, reaction time data for all keypresses recorded in a Keypress Response were calculated from the onset of the response (when the response is rendered on the trial). Based on feedback, we have decided to instead calculate the reaction time of each successive keypress relative to the preceding keypress, with the first keypress reaction time calculated from response onset.

In other words, if a participant were to strike a key every 500ms, the old reaction time data would look like this: 500, 1000, 1500, etc. It will now look like this: 500, 500, 500, etc.

2. Choice Responses now support dropdown selection!

It is now possible to organize the options of a choice response in a dropdown menu by setting the “mode” property to “dropdown”. Dropdown mode supports feedback and resetting of the choice response, but does not presently support the “multi_select” parameter (this will be made available in a future release).

A big thank you to Dr. Ming Xiang of University of Chicago for requesting this feature!

3. Tokenized Text Stimuli now support bidirectional self-paced reading!

It is now possible for participants to move both forward and backward through tokenized text stimuli. Simply set the new “bidirectional” property to true. This feature is particularly useful for backward-masked and singleton self-paced reading setups.

Please note: This feature is only possible if “self_paced” is set to true. In addition, please see the new “key_reverse” property which supplements the “key_advance” property to support custom key bindings.

A big thank you to Dr. Jeffery Green of BYU Dept. of Linguistics for requesting this feature!

4. Changes to Tokenized Text Stimulus instructions

With the addition of bidirectional tokenized text stimuli, we are deprecating the old “key_advance_instruction” property in favor of a new “hint” property. This aligns key advance instructions across tokenized text and audio stimuli.

Please note: Studies employing the old property should continue to work for now, but we do not actively support deprecated features.

5. A bug fix affecting the recording of Response Mode in the results CSV

A bug affecting how “response_mode” was recorded in the results.csv file of a completed session or study preview from grammar version 3.5.0 has been fixed. The response mode is now correctly recorded.

If you have any questions regarding this grammar update, please leave your comments below. Thanks!

  Multiple stims on trial but presented sequentially
Posted by: atfrederiksen - 08-11-2023, 05:09 PM - Forum: Study Grammar & Management - Replies (2)

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?

  Image overlay onto the another image
Posted by: sykim21 - 08-10-2023, 04:25 AM - Forum: Study Grammar & Management - Replies (3)

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?

  Experiment Won't Show Images
Posted by: NateHHeller - 08-05-2023, 03:20 PM - Forum: Study Grammar & Management - Replies (8)

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?

  Branching issue
Posted by: ytgu - 08-03-2023, 11:33 PM - Forum: Study Grammar & Management - Replies (2)


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!

  Study Not Loading on MTurk
Posted by: finley - 07-09-2023, 02:54 PM - Forum: Platform Improvement - Replies (3)

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?

  Problems with creating an account - RECAPTACH
Posted by: Paweł Stefański - 06-25-2023, 07:02 AM - Forum: Study Grammar & Management - Replies (3)

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.
Paweł Stefański
