Using customisable staircases or MOCS, the researcher can control presentation of any stimuli that can be precomputed as PNG image files, including movies. Features include participant accounts, up to 4 response buttons, comprehensive log files, and remote test configuration using the PsyPad server. A demo mode with access to a public gallery of tests also makes PsyPad useful for teaching.
