Flanker Task
Introduction
The flanker task, also known as the Eriksen flanker task, was designed in the early 1970s by Eriksen and Eriksen. Like most of the paradigms in this library, it is popular and there are many variants of the original.
The basic effect is that when you need to respond to stimuli "flanked" by irrelevant stimuli, the irrelevant stimuli can still affect your response. There is a similarity between other paradigms in which this type of interference from an irrelevant stimulus or stimulus feature occurs (like the Stroop task or the Simon task).

About this implementation
The flanker task here is slightly different from the original flanker task from Eriksen and Eriksen (1974) for various practical reasons (this version is just a bit easier). For example, in the original study, the spacing between the letters was varied, and in addition to compatible and incompatible letters, there were neutral letters. Of course, you can extend the code to add those features of the original study.
In this task, you need to respond with the A or L key of your keyboard. This matches the original task’s left or right lever press (A and L are left and right on the keyboard, respectively).
Frequently Asked Questions
What is the Flanker task?
The Flanker task is a cognitive psychology test to assess attention and the ability to suppress responses to distracting stimuli.
Trial Flow:
Each trial presents a row of letters. Focus on the center letter and press the correct key as quickly and accurately as possible. Ignore the surrounding letters (flankers).
Feedback:
After each response, you will receive feedback indicating whether your answer was correct or incorrect.
