What We Do

UC Berkeley Researchers conduct a variety of experiments and studies at Xlab. These may involve decision-making tasks, surveys, games, interviews, and group activities. Many experiments are held in the Hearst Gymnasium, but we also offer online and mobile experiments that you complete remotely. Studies compensate your participation on average with $15 per hour.

You must be 18 years or older and a UC Berkeley Student or Staff to participate.

Please note that berkeley.sona-systems.com, used by Xlab to post studies, includes paid studies from Behavioral Lab and Psychology Department. Different labs may operate under different rules, policies, and procedures. Please refer to their websites to be informed and take careful note of the location when signing up for experiments: Behavioral Lab websitePsychology website.
