PsychToolboxhas resisted the upgrade to a 64-bit codebase for some time. The recent 3.0.9 update introduces 64-bit support on Linux only, and Mario Kleiner promises that in this version, […] the extra bits provide you with 50% higher effect sizes, higher d’ and greater levels of significance with less subjects, whatever you’re measuring. Well maybe … More Psychtoolbox – Now available for 64-bit Linux
There’s a new project for coordinating large scale psychophysics and neurophysiology in Matlab called Snow Dots. It uses PsychToolbox as a presentation layer and builds a framework around it to automate experimental flow, do GUIs, move data around, etc. It’s a little too Java-ish for my tastes (I’m a lightweight, convention over configuration kind of … More Snow Dots project for psychophysics, neurophysiology in Matlab
Although PsychToolbox is very easy to get up and running, implementing a full experiment takes time. PsychToolbox is a toolbox, not a framework; there are no constraints on how you should organize your programming. If your programming is well-organized, it’s easy to modify your experiments, understand how a program works after you haven’t touched it … More A case study in PsychToolbox
Another PsychToolbox tutorial, this one from Keith Schneider at Rochester U. Included are code for a binocular rivalry task with anaglyph glasses support, a flickering checkerboard fMRI stimulus for retinotopy mapping and random dot fields. If I have time I’ll package these into .m files and add to the PsychToolbox code.
Ariel Rokem at Berkeley has a beginner-level PsychToolbox tutorial with sample matlab code. Most interesting is a ready-made face adaptation experiment. Nice work.
