Perform basic interactions with your data acquisition device
After installing Psychtoolbox and the DATAPixx toolbox, launch MATLAB. After a brief overview of important DATAPixx toolbox functions, you will be prompted to open a pre-existing MATLAB script containing a basic stimulus loop.
This file is included in the downloaded materials from this session, and is called IntroRPx_StimulusSetup.m.
If you run the script before completing the tutorial, you will only see a static grey image, visible for a short period of time.
When you execute IntroRPx_StimulusSetup.m before completing the tutorial, the white and black squares alternate too rapidly to be individually perceived. At this stage, you will only see a static grey image, visible for a short period of time.
