Stimuli present in various monitors

Input and response

Support for touch devices such as iPads, iPhones, and Windows Surface devices.
Measurement of millisecond accuracy response time for mouse, touch screen, keyboard, serial and parallel port devices, and response boxes.
Gauze point logging and contingent task paradigms with Tobii eye trackers with the Inquisit 5 Tobii Plugin.
Provide response feedback using any kind of stimulus.
Support for response times and response windows that can be adjusted according to integrated or customized performance metrics.
Provide rich performance feedback based on latency and response accuracy.
Record, track, and report custom or integrated performance metrics.
Support for voice key response measurement using a standard PC microphone and sound card.
Support for tasks that involve drawing on screen, such as trail making test
Use speech recognition to measure the accuracy and latency of spoken responses.
Record the spoken response for manual or automatic analysis using speech recognition.
Program tasks that use drag/drop.
Use any DirectX-compatible joystick (Windows only).

Task Flow, Conditional Branching, User-Selected Stimulus Sets

Easily create dynamic tasks that adapt based on a wide variety of variables, including sophisticated performance metrics, elapsed time, test counts, randomly selected values, and more.
Create stimulus sets based on user responses and performance metrics. Allow participants to select from stimulus matrices displayed on the screen. Continuously add and change stimulus items during the course of an experiment.
Define custom variables and update their values at the beginning or end of assessments, blocks, or experience.
Support for a wide variety of experimental designs, randomization schemes, and task paradigms, including reaction time measurements, game tasks, memory tasks, behavioral economics tasks, learning tasks, and more.
Design adaptive tasks with sophisticated jump, repeat, and branch algorithms based on subject performance, elapsed time, test and stimulus count, and more.
Powerful demonstration capabilities for presentations and lectures. Ability to selectively perform individual tasks, assessments, blocks, search pages and stimuli.
Random or predetermined attribution of participants to the conditions between the subjects.
Group multiple scripts and measures.

Web Resources

Easy-to-use, browser-based tools for uploading scripts to the web.
Easily and securely monitor and download data files from a password-protected account.
Support for all major browsers, including Chrome, Internet Explorer, Firefox and Safari.
Interoperate with third-party web products such as Mechanical Turk, Qualtrics, Unipark, and Survey Monkey.
Support for administering a given test in multiple languages, depending on the locale of the participant's operating system.
Easily redirect participants to other web pages at the end of an experiment

Data recording

Data is saved in a non-proprietary tab-delimited text format that can be easily imported into Excel, SPSS, or any data analysis package.
Save data files to the local computer, network sharing, web sites, ftp site.
Select any of the internal Inquisit variables and statistics to record in the data file, or calculate and record your own custom metrics.
Save raw data from each test, as well as performance statistics ready for analysis.
Assign numeric or non-numeric identification codes to participants.
Password encrypt your data files to protect sensitive information.
Record survey and survey data in a simple line by subject format.

Productivity features

Inquisit is based on a declarative, easy-to-use scripting language similar to HTML. Simply set the properties of your stimuli, tests, try blocks, and experimental sessions, and Inquisit takes care of the entire flow of the program.
Inquisit's rich script editor includes colorization, autocomplete, syntax validation, error reporting, help integration, and script visual navigation, making it easier than ever to find and use Inquisit commands.
Data editor to view data files with a spreadsheet UI, sorting, and filtering
Help system, tutorials and samples. Get quick contextual help in the Inquisit scripting language by pressing the F1 key in the text editor.
Visual designers to select font styles and colors.
Inquisit supports previous versions so you can run all your old scripts without changing them.
Easy methods to obtain informed consent
Start experiments from the command/terminal prompt directly or from other software applications.
Define commonly used elements (for example, stimuli, evaluations, how-to pages) in shareable script files that can be imported by other scripts.

Surveys and questionnaires

Displays multiple questions per page.
Support for a wide variety of question formats, including radio buttons, check boxes, listboxes, sliders, and open text input.
Allow users to navigate back and move through pages, or enforce only forwardnavigation.
Text entry with valuable validation rules covering almost any input format. Use built-in validation rules for common data, such as dates, phone numbers, postal codes, email addresses, or create custom validation rules using regular expressions.
Gather classifications along continuous scales (also known as Visual Analog Scales) in which responses are made by moving a slider back and forth or up and down along a continuum.
Conditionally add or skip pages based on previous responses, elapsed time, random selection, and a wide variety of other variables.
Embed stimulus sequences in a survey, including text signals, images, video, sound, and port.
Perform standalone or seamlessly integrated searches for performance measures.
