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.

Snow Dots project for psychophysics, neurophysiology in Matlab

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
