Inquisit 3 Overview

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. Click here for a comprehensive feature list.

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.

How do PC licenses work?
A single desktop license is required for each PC on which you wish to install and register Inquisit. The license enables you to collect unlimited amounts of data on a registered PC. If a PC is replaced, the license can be easily transferred to the new one. Desktop licenses do not expire; you can use them as long as you want. You can run any Inquisit script, whether it came from our task library, a colleague, or you created it yourself.
