stroop | A console-only Github Issues board inspired by Waffle.io | Command Line Interface library

Hi i am running an experiment which has 120 trials. i want to add a break in the loop every 30 trials and wait for the participants to press a key when they are ready to continue. my code for the loop looks like this

I am using a custom excerpt in my blog post, but I got an empty output if the length of excerpt is too long.

If I reduce some words in excerpt, then it worked. Do you have any ideas how to fix it?

Thank you

My post configuration:

I need to develop a simple interface for Stroop test using Python, but I don't know how to start it in Python.

The interface would be like:

10 seconds in a blank screen, the 10 seconds with a colored word on the center of the screen. This would repeat like 10 times, then finish the application.

The problem is: I don't know if I have to use Tkinter + anothe lib (timed events), or if Tkinter provides the methods to use timed events.

Could anyone enlight me,please?

Thank you very much!

I'm working on a small C# Winforms application that replicates several visual experiments concerning cognitive psychology. Instead of using premade images, I was trying to create them programmatically to train my skills.

Now I'm working on the Stroop Effect and I'm attempting to reproduce the following image:

I prepared two distinct arrays, one containing the colors and one containing the name of the colors:

I created a Stroop-like reaction time task in MATLAB and looking at pilot results suggests there might be something wrong with my code (the congruency effect is much bigger than expected). I suspect I may be recording RTs wrong, so could anyone help me out with whether the following setup is okay?

On any given trial, two events happen (following a fixation cross): first, the target stimulus is presented for a max of 3 seconds (or until response), then the participant has to press a button to start the next trial. RT for both buttonpresses (target and trial-start button) is recorded. Here's my code:

Below is some background information about my dataset if you want to understand where my question comes from (I actually want to merge datasets, so maybe somebody knows a more efficient way).

The question: How to replace only the final character of a variable name in R with nothing (for multiple variables)?

I tried using the sub() function and it worked fine, however, some variable names contain the character I want to change multiple times (e.g. str2tt2). I only want to 'remove' or replace the last '2' with blank space.

Example: Suppose I have a dataset with these variable names, and I only want to remove the last '_2' characters, I tried this:

This is a simple script that is used to calculate Z scores of some neuropsychological tests.

But recently the code seems to be running on the background even after exiting the program. This problem didn't exist before, I use the following startup piece to ensure program is running with elevation, and is correct size for the display.

Program can be shut down using a "exit" command that raises SystemExit or just by pressing the X button on the top bar. Program keep running on the background regardless.

Where did I go wrong?
