Space between two phrases |

Hello!
I was wondering whether I could make some space between two phrases.
For instance, I want to create a stimulus that shows "a key to lock".
However, when I made some space manually between the two phrases using a spacebar and run a preview, the two phrases were adjacent without any separation.
So instead, I used dashes and this is how I coded for this stimulus:
{
"type": "text",
"content": "a key----------------------------------to lock",
"alignment": "left",
"size": "50px"
}
However, I'd like to know whether there is a way to make some space between the two phrases without using dashes.
Thanks!

Problem uploading zipped audio files |

I've uploaded several sets of zipped audio files to "Files" and while these uploads were "successful" none of the files are showing in the list of files, and none of the files available for use in stimuli, they're missing. However, with each "successful" upload, the "memory meter" shows space has been taken up by the no-show files.

Prolific ID Missing |

Hello, I am piloting a study in which participants are redirected from Prolific to Finding Five. In order to match their FF study data with their Prolific demographic data, the first thing I have them do when they start the FF study is enter their prolific ID into a text response.
Unfortunately, 3 out of the first 10 pilot subjects did not have that response recorded! That row in their data is simply missing.
What are some reasons why that response isn't being saved?
This is a pretty crucial step in my study, so any help you can offer in sorting the issue out would be much appreciated!
Best,
Nate

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

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]},
{"which":["Acupuncture-Easy-Manipulation","A_E_C_2"],"location":[2,8]},
{"which":["Acupuncture-Easy-Manipulation","A_E_C_3"],"location":[2,8]},
{"which":["Acupuncture-Easy-Manipulation","A_E_P_1"],"location":[2,8]},
{"which":["Acupuncture-Easy-Manipulation","A_E_P_2"],"location":[2,8]},
{"which":["Acupuncture-Easy-Manipulation","A_E_P_3"],"location":[2,8]},
{"which":["Acupuncture-Easy-Manipulation","A_M_C_1"],"location":[2,8]},
{"which":["Acupuncture-Easy-Manipulation","A_M_C_2"],"location":[2,8]},
{"which":["Acupuncture-Easy-Manipulation","A_M_C_3"],"location":[2,8]},
{"which":["Acupuncture-Easy-Manipulation","A_H_C_1"],"location":[2,8]},
{"which":["Acupuncture-Easy-Manipulation","A_H_C_2"],"location":[2,8]},
{"which":["Acupuncture-Easy-Manipulation","A_H_C_3"],"location":[2,8]},
{"which":["Acupuncture-Easy-Manipulation","A_H_P_1"],"location":[2,8]},
{"which":["Acupuncture-Easy-Manipulation","A_H_P_2"],"location":[2,8]},
{"which":["Acupuncture-Easy-Manipulation","A_H_P_3"],"location":[2,8]}],
"responses":["A_E_C_1_R","A_E_C_2_R","A_E_C_3_R","A_E_P_1_R","A_E_P_2_R","A_E_P_3_R","A_M_C_1_R","A_M_C_2_R","A_M_C_3_R","A_H_C_1_R","A_H_C_2_R","A_H_C_3_R","A_H_P_1_R","A_H_P_2_R","A_H_P_3_R"],
"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]},
"Post-JOL-Q"],
"responses":["A_E_C_1_R","JOL-Post"],
"duration": 60,
"countdown_visible": true
}
Thanks!

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

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