Shane T Mueller posted a comment on ticket #23
Hi, this is the old launcher and no longer is supported. I'm not sure exactly how you ran it, so maybe I had something in the standalone package misconfigured. There should be a pebl-launcher.exe in the bin/ directory that allows you to run the new launcher, but I'll need to check out how to access it.

I think the pursuit rotor instructions are very limited and progress as soon as you hit a key. You might edit the file and after the MakeWindow() line add a MessageBox("instructions here", gWin). This will add a new instructions page and you can add whatever text you want. I am nearing release of PEBL 2.2, and have files staged for release at https://sourceforge.net/projects/pebl/files/pebl/2.2/ You may have better luck with these, although there have been a massive amount of changes, updates, and...

Hello, I have created an experiment chain with the Pursuit Rotor Task and n-Back Task for an upcoming neurodevelopment study my lab is running. My current issue is that anytime I launch the experiment, which I do from the launcher, the instructions associated with the PR task do not appear. I have no issues with the instruction functionality for the n-Back task, so I have been unable to identify the root cause of the problem. I am quite new to PEBL and coding in general, so any guidance would be...

I don't know what the anticipation test is, so I don't think so. I'm about to release a new release in the next month and I'm removing the nag screen on the launcher--we will have a comprehensive on-line system which will be a better way of supporting PEBL development. Email me at my mtu.edu account if you'd like the current password.

What is the syntax error? Did it give a line number? I'm not seeing an error like that when I run it. I've added a beep stimulus that gets played when the 'x' appears. Note that you will need to edit the instructions to specify that they need to hit the 'x' key, although you can change the parameters to use another key using the edit parameters dialog. I guess if they are blind, you don't need to change the instructions on-screen, you just need to show them which key to press. You can update the...

Dear Mueller, I am writing to seek assistance regarding an issue I am encountering with the PEBL software. Among other measurements, i also conduct Stroop test. As I am working with Slovenian participants, it is essential for the Stroop Test to be translated to the Slovenian language. I have reviewed the PEBL manual and several forums to guide me through the process of translating the test. Specifically, I translated the english .csv file, added the abbreviation sl for the language, and saved the...

Hello, I am analyzing the data found here: https://www.nature.com/articles/s41597-021-01046-y, which contain ptracker files. The files consist of several columns (see attachment).

By reading https://sourceforge.net/p/pebl/discussion/281130/thread/f220064d/ and looking at my files I think that "posX and "posY" correspond to the x and y coordinates of the ball in regard to the center of the circle.

Shabina Hawaldar posted a comment on discussion Experiments
Thank you for your suggestions, I will consider using other tests.
-
You might want to consider something like the continuous performance task (PCPT) modeled after conner's CPT; or another go/no-go task like TOVA or the oddball task. The tempo of those tasks is a lot faster (1/sec or so instead of 1/minute). You get more data, and it is probably a better measure of general sustained attention and vigilance decrement than PVT which is really designed to catch people literally falling asleep after sleep deprivation.
-
Sir, Thank you for your response. As I would be comparing sustained attention by using PVT reaction time in binocular vision anomalies in my research, I would like to know if the PVT reaction time measured by this test will provide with an accurate measure of sustained attention? Eagerly waiting for your response Thanking you Shabina

I am extremely new to this program. When I open an experiment and hit run test, the participant number changes every time but it comes up with an error message and I can't actually run the test. I have closed it, restarted it, restarted my computer, etc. The error says the problem is within a file but we can't find it or even know what we are looking for. Any tips?
-
Shabina, PVT is normally used to test sleepiness/sleep deprivation, so the metrics reported are usually specifically about that (sleep lapses, etc.). The raw data has the following columns: sub,block,trial,ISI,ISIbin,abstime,rt,type ISI is the inter-stimulus interval, and ISIBin is the bin (there is some randomness). There are four categories of response: 1=too fast, 2=correct, 3=lapse 4=sleep attack, where lapse is a response longer than 500 ms and sleep attack is one longer than 30 s. These are...

This may be a bit more of a theoretical question than a question specifically about PEBL, but for the Simon task, how should circles that show up at position 0 (center) be counted in terms of congruency?

The summary stats saved to the report are pretty minimal, and should be computable easily via excel or R or Python code. I just keep track of, for single and switch trials separately: Number of targets (The more the better) RT (should not even differ because there is a 20 second time limit in both conditions) Clicks (counts extra clicks, probably not useful; essentially the same as targets) overclicks (even less useful probably) Here is a sample file: --------------------------------------- Mode:...

BTW, this isn't C++. You can hard-code trials by either calling 'MismatchTrial()' or 'MatchTrial()'. Assuming you want a couple match trials at the beginning of a block, you can pick a random row from the stimulus table stimAll and use that. These get recorded to the data file so you need to print the first columns of the CSV too. The following code will handle it: ## do a practice trial i <- Sample(stimAll) FilePrint_(gFileOut, gSubNum + ",Practice,0,") MatchTrial(First(i), Nth(i,2),Nth(i,3),Nth(i,4))...

Hi Leanna, Since Shane has made all codes open source, you may use the IAT source codes to create your modified task. As I have not looked into the IAT specifically, I can't tell you what exactly to do. But you may try figuring out how the number of trials and its stimuli have been specified in the original code, use the same information at the beginning, and change the number of trials and stimuli type for the practice. Of course, differentiating instructions between practice and actual task will...

Thank You sooooo much Shane you are a HUGEEEE help. Now unfortunately my professor is wanting a practice trial to be at the beginning of the first trial? again I am stumped I wish I was better at C++ language. could you by any chance point me in the right direction on the syntax of how I would go about doing that? If that is too much to ask I completely understand :) and thanks for your swift response !
-
There are a couple additional tweaks needed to get the coding correct. See attached--this should work except for any additional instructions you may have added.

To fix this, you just need to go into the IAT.pbl file using a text editor like notepad++. Change two lines (474 and 525) from: response <- WaitForListKeyPress(["1","2"]) to response <- WaitForListKeyPress(["I","E"]) and at line 482: if(ToNumber(lgoodness)==1) { corrResp <- 2 } else { corrResp <- 1 } to if(ToNumber(lgoodness)==1) { corrResp <- "I" } else { corrResp <- "E" } and if(type != lgoodness) { corrResp <- 1 } else { corrResp <- 2 } to if(type != lgoodness) { corrResp <- "E" } else { corrResp...

Hello, I'm having problems with the n-back task. Actually, I just don't know how to change the task.

Dear Prof. Mueller, This query is with reference to the way reaction time is calculated in color stroop task in PEBL.

For the SRT task, the file below contains the code to allow use of the mouse button. You will also need to update the translation .json file and the parameters file, which I'll attach to subsequent comments. To make it work, you will need to set the 'responsekey' parameter to 'mousebutton' from 'X'. The json file goes in translations\ and the .schema file goes in parameters\

Jack, Neither of this is too difficult, but both are written to look specifically for key presses and the function needs to be replaced to handle mouse events. This is complicated in both cases by the fact that these are done with a timeout, so you need to be able to handle the condition that a response is not made. For the tapping task, you need to replace line 184 with some code to look for the mouse keypress instead of keyboard. Note that because the physical switch is different, the results would...

I have several alternative fonts that support a range of asian characters (like fireflysung and wqy-zenhei and UnbBatang), but I believe Devanagari is right-to-left, and PEBL doesn't really support that--it requires a special text renderer that PEBL does not incorporate. It might be possible to fake it by typing the stimuli backward, but I'm guessing spacing and ligatures might be all wrong. To try this, you need to change the default font. One way to do this is to set the language in the launcher...

Alphan, Just edit the dexterity.pbl file in a text editor like notepad++. Go to line 107 and change Show(tb.text) to Show(tb) And that should fix it.

I've updated the sourceforge repository and it should be fixed in the next release.

Hi, Is it possible to use two different languages in the Lexical Decision Task? I.e. instead of words/nonwords, English/Devanagari letter strings? I have tried creating a new .txt file with Devanagari letter strings and saved it in UTF-8, but when the test is run, PEBL just shows boxes for those words. (Devanagari characters are not supported by DejaVu)
