In this video you learn how to create a Flanker task using the Python package Expyriment. If you don’t know Expyriment it is an open-source library. You can program your experiments and run on Linux, Windows, and OS-x computers and Android devices.
In the tutorial you will get familiar with Expyriment and get to create a commonly used task in Psychology – the Flanker task. In this task, you are to respond in the direction of an arrow surrounded by distractors (arrows pointing in either the same or the other direction). It shows how hard it can be to ignore irrelevant information (arrows pointing in the wrong direction).
