Open Source Cognitive Science

A new site with the self-explanatory name of "Open source cognitive science" has an interesting opening post about Tools for Psychology and Neuroscience, pointing out that:

Open source tools make new options available for designing experiments, doing analysis, and writing papers. Already, we can see hardware becoming available for low-cost experimentation. There is an OpenEEG project. There are open source eye tracking tools for webcams. Stimulus packages like VisionEgg can be used to collect reaction times or to send precise timing signals to fMRI scanners. Neurolens is a free functional neuroimage analysis tool.

It also has this information about the increasingly fashionable open source statistics package R that was news to me, and may be of interest to others:

R code can be embedded directly into a LaTeX or OpenOffice document using a utility called Sweave. Sweave can be used with LaTeX to automatically format documents in APA style (Zahn, 2008). With Sweave, when you see a graph or table in a paper, it’s always up to date, generated on the fly from the original R code when the PDF is generated. Including the LaTeX along with the PDF becomes a form of reproducible research, rooted in Donald Knuth’s idea of literate programming. When you want to know in detail how the analysis was done, you need look no further than the source text of the paper itself.
