Guide to OpenSesame
OpenSesame is an open-source software package for building and running psychology experiments. It's written in Python and is available for Windows, OS X, and Linux systems.
Using a button box with OpenSesame
The File:SRBoxexample.opensesame.tar.gz provides a demonstration of how to collect button presses in an OpenSesame experiment.
In this example the basic pattern of presenting a stimulus and waiting for a response proceeds in three steps. Take a look at the experiment overview:
First, text is displayed to the subject by the 'intro' text display item. By default items of this type wait for a keypress, but we change the default 'keypress' value of the Duration property to '0' to cause the script to immediately execute the following item.
The next item is the intro_response srbox item, which is the interface to the button box. The script will wait here until an allowed response is provided. In this case only button 3 (the middle button) is allowed. The semicolon-separated list '1;3;5' indicates that button lights 1, 3, and 5 will illuminate.
