Paradigm's unique Event Sequence interface enables you to quickly build your experiment by adding stimulus events from the toolbox. You can copy and paste a single event or an entire block of events anywhere in your experiment. Create complex visual stimuli presentations using Paradigm's designer surface. The designer surface supports rich text, images, videos, self-paced reading and rating scales. Paradigm's built-in mouse selection allows subjects to click on any visual stimulus as a response making it ideal for identification, visual-world paradigms and rating scales. Take the tour...

Distribute "stand-alone" experiments over the web or in your lab without the need to buy additional licenses. With one click, Paradigm will package up your experiment, stimuli and the Paradigm runtime into a Windows installer for easy distribution. Experiments distributed as stand- alones do not require a Paradigm license, so you can build once and run anywhere.

Paradigm has undergone rigourous testing to ensure millisecond accurate stimulus presentation and response time measurement. All of our timing tests are done with the Black Box Toolkit to ensure objective and reproducible measurements. View timing measurements...

The vast majority of Paradigm experiments will not require script at all but sometimes a little script is the easiest way to achieve the experiment design your after. Paradigm gives you complete access to every event in your experiment through its scripting interface. Using the popular Python scripting language you can change event and device properties as well as experiment flow.

Present text stimuli in any language. Paradigm supports all international fonts including Cyrllic, Arabic and Chinese.
