This web page presents information about the research going on in our laboratory. To make it useful we have several programs you can run and a couple of movies to demonstrate the diffusion model for simple two-choice decision (is this a word or not, is this line long or short, is this display bright or dark, did I study this word or not, etc.). A description of the model is presented in the research topic "Diffusion Processes" and programs take parameters of the model as input and produce predictions of the model as output.

Demonstrations, etc.
