If you are interested in taking the test for yourself now, go to either the brief demo or to the full online version of the test. You can also download the full version to customize and use Panamath on your own computer or in your own research. The downloadable version of Panamath is a free, self-standing software that can run on Windows, Mac, or Linux. There are default settings in the program that you can change according to your subjects. Upon completion of the test, Panamath generates two output files: a reader-friendly PDF that explains the subject's results and an XLS file containing trial-by-trial accuracy and response time data and stimuli parameters. The results files will be saved to your own computer. You retain all rights to any data that you collect, and we cannot access your data.
