What is Inquisit?

Inquisit is general purpose psychological measurement software that can be programmed to administer almost any psychological measure or experimental paradigm. You can download any of the ready-to-use tests from our task library, modify those tests, or create innovative new measures.

Collect data in the lab or online

All tests are executed by the Inquisit Test Engine, a flexible, high performance platform that provides millisecond precision timing of stimulus presentations and responses. The engine can be installed as a traditional desktop application for use on dedicated PCs. It can also run experiments over the web without sacrificing functionality and performance. (Note - Inquisit currently runs on Windows only. It does not yet run on Macs.)

How do web licenses work?

A single web license enables you to have one experiment online at a time, with no limits to the number of participants who can run the experiment simultaneously or in sequence. When an experiment is complete, it can be replaced with a new experiment. Additional web licenses can be purchased to support multiple studies online at once. You can run any Inquisit script, whether it came from our task library, a colleague, or you created it yourself.
