Inquisit is a psychological experiment software product developed by Millisecond, designed for research applications in psychology and related behavioral sciences. The software is available in two versions, with the current release being version 7.3.1, and falls within the category of scientific research and experimental psychology tools. Its primary component, Inquisit Lab, transforms a Windows or Mac computer into a local psychological testing platform, enabling researchers to administer and program psychology experiments directly on standard desktop hardware. A key characteristic of the platform is its local data handling approach: experimental data is saved directly to the device on which the test is run, which supports controlled, on-premises research environments. Inquisit Lab supports the creation of custom tests, allowing researchers to design experiments tailored to their specific study requirements rather than being limited to prebuilt paradigms. Beyond standard computer-based testing, the software offers integration with external research hardware, including EEG systems, fMRI equipment, and eye trackers, making it suitable for neuroscience and cognitive science studies that combine behavioral measures with physiological or neuroimaging data. Typical use cases include academic and institutional research settings in which investigators need to program experimental tasks, present stimuli to participants, record responses, and collect synchronized data from connected measurement devices. Because it runs on conventional Windows and Mac computers, Inquisit Lab can be deployed in laboratory environments without requiring specialized proprietary hardware for the testing platform itself. The product's combination of local experiment administration, customizable test programming, local data storage, and compatibility with EEG, fMRI, and eye-tracking technologies positions it as a flexible tool for researchers conducting psychological and neuroscientific investigations. With version 7.3.1 representing the current release among its two available versions, Inquisit continues to serve as a dedicated solution for building and running psychology experiments in research contexts.
