Tatool

Tatool Web is an open-source, browser-based platform for designing, running, and managing behavioral and cognitive psychology experiments. It is built to support researchers, instructors, and students who need a flexible, easy-to-deploy solution for reaction-time tasks, cognitive training paradigms, and online behavioral studies—without requiring advanced programming expertise. Because Tatool Web runs entirely in the browser, participants can complete studies remotely on any modern device.

Key Features

Experiment Builder

Tatool Web provides a visual and modular experiment builder, allowing researchers to create trials, blocks, feedback routines, stimuli presentations, and timing-dependent tasks without writing code. You can mix text, images, audio, and interactive elements using prebuilt components.

Custom Task Programming

For more advanced users, Tatool Web allows custom task logic through JavaScript modules. This enables implementing classic paradigms such as Stroop tasks, N-back, task-switching, working-memory tests, and more complex reaction-time–sensitive workflows.

Cloud-Based Data Collection

All experiments can be deployed online via the Tatool Web server or a self-hosted instance. Participant data—including responses, reaction times, and metadata—is recorded automatically and can be downloaded in structured formats for analysis.

User & Participant Management

The platform includes built-in tools for:

• Managing participant accounts
• Assigning specific training or testing modules
• Monitoring progress and completion
• Running longitudinal cognitive-training studies

Open-Source & Extensible

As an open-source project, Tatool Web encourages researchers to develop their own modules, extend existing tasks, and share paradigms with the broader community.

Use Cases

• Cognitive psychology experiments (attention, memory, executive function)
• Reaction-time-based behavioral tasks
• Online training studies and longitudinal cognitive interventions
• University teaching labs that need easy-to-run cognitive tasks
• Remote behavioral research where installation-free deployment is essential
