Research Software

Software written by Andrew Wilson
I mostly use Matlab to run experiments and analyse my data. I use the Psychtoolbox to control my stimuli; this is a free third party Matlab toolbox that provides tight control over graphics timing and a variety of methods for producing stimuli.

Masked Priming Toolbox v1.1
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 PTB-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.

Tracker Video Analysis and Modelling Tool: Tracker is a free video analysis and modelling tool built on the Open Source Physics (OSP) Java framework. It's a great way to do simple motion analysis, and to introduce students to the principles of kinematic analysis. If you're interested in what it can do, have a look at this post on Wired about the physics of the yellow Angry Bird.
