Example masks and stimuli from Wilson et al (2011)
I was a post-doctoral research fellow for a year at the University of Warwick, using masked priming tasks to investigate action selection with Friederike Schlaghecken and James Tresilian. To run the experiments we needed, I wrote a Matlab toolbox using the PyschToolbox-3 that presents various kinds of masked stimuli and records responses from keyboards (for reaction time), as well as tablets (for 2D kinematics) and one kind of force transducer. It handles all aspects of stimulus presentation, data analysis (including an extensive set of kinematic analyses), and is freely available for researchers to use under a liberal Creative Commons license. I only ask that if you tweak or add anything to the toolbox, that you send me a copy so I can keep an up to date version available here.
