Release of our Bayesian Causal Inference Toolbox

Dear colleagues,

I would like to announce the beta release of Bayesian Causal Inference toolbox (BCIT), developed at the UCLA Multisensory Perception Lab:

BCIT is a MATLAB toolbox developed for learning and using the Bayesian Causal Inference Model of multisensory perception. This NSF-sponsored toolbox was developed for two aims: a) serving as a pedagogical tool for learning and understanding how the model works, and b) for adapting and using the model to explain experimental data in a variety of experimental paradigms. The toolbox is designed for use by researchers of any background, and does not require any computational training or skills.

This is a beta release and we welcome feedback on the existing functionality, as well as suggestions for additional functionality to be added in future releases. Please email the lead developer Dr. Majed Samad ( or the assistant developer Kellienne Sita ( with any questions. Please cc me ( on your emails.

We look forward to your feedback.

Best regards,

Ladan Shams

Shams Lab featured on TV

As part of its “Myth or Science” series, the Canadian TV show The Nature of Things aired an episode on sensory perception. The episode featured a segment on our lab that included an interview with Prof. Shams and a demonstration of the rubber hand illusion by our own Majed Samad.

A trailer for the episode can be seen here.
Viewers in Canada can watch the full episode here.
