The Psychomotor Vigilance Test (PVT) is a widely used cognitive test designed to assess sustained attention and reaction time. It is the de-facto gold standard for objectively assessing behavioral alertness and very sensitive to sleep loss and circadian misalignment. Furthermore, due to its simplicity, the PVT is not affected by aptitude or practice effects like the majority of other, more complex cognitive tests.

How it works?

The PVT measures response times to stimuli that are presented at random inter-stimulus intervals. The precise measurement of these response times is of critical importance for the validity of the PVT. The test records reaction times, lapses, false starts, etc.

Key Advantages

• Sensitivity to Subtle Changes:

The PVT can detect even small impairments in attention and alertness.

• Minimal Practice Effects:

Repeated testing with the PVT does not significantly affect performance, allowing for reliable longitudinal assessments.

• Ease of Administration:

The PVT is a simple and straightforward test that can be administered in various settings.

Applications of PVT

• Sleep Research

• Occupational Settings

• Medication Research

• Aging Research

• Sports and Exercise Science

Web-based PVT by NeuroUX

‍NeuroUX offers a web-based version of PVT which ca be administered on a smartphone web browser, enabling participants to perform the test on their devices without the need for app installation. The test can be accessed through a simple text message link.

Available Versions:

• PVT (Standard Version):

This version replicates the traditional PVT with a 10-minute testing duration. It offers comprehensive data on sustained attention and reaction times, making it ideal for in-depth studies.

• PVT-B (Brief Version):

Our PVT-B condenses the traditional format into a quick 3-minute assessment. While more compact, it retains the core features necessary for meaningful insights, offering a balance of efficiency and precision.

Both versions are accessible via our web-based platform, ensuring seamless integration into remote or in-lab studies.
