Neuroscience programming with psychopy/python: Line Bisection Task (Video 5) - GUI interface

Описание: In this series of videos we will be using Psychopy and Python (version 3) to create the line bisection task. If you would like to know how to go about creating and designing a working Neuroscience experiment using Python programming language, then this is a nice and gentle introduction.

The line-bisection task can be used to probe visual-spatial attention / visual neglect in people with impaired parietal lobe function. More specifically, in this task we present our subjects with a transected line and ask them to decide if the left (or the right) side of the line is longer or shorter. In some of the trials, we will present a line that is perfectly bisected (so left and right are the same). We will base our experiment off a previous paper (Kim et al., 2005 Neuroscience Letters) and build a working program from scratch.

In this particular video we will use psychopy to create some GUI (graphical user interfaces) that will help organise our experimental data files and save file names. Up until now we have ‘hard-coded’ the save file path names and subject information. By making some GUI elements, we automate a lot of this work and help ensure our data files are standardised. The way that I create the save file names may not be appropriate for your research lab or institute, and therefore I suggest you find out how you need to name your files.

All of the code is written on the screen at a speed that should be easy to reproduce. All programs are open-source and all you will need is a working Python3 installation and working Psychopy Installation.
