The VRLAT is a research tool that enables quantification of the severity of left hemispatial neglect in a virtual environment that places realistic demands on attention, visual search, and ability to multi-task.
The VRLAT allows participants to name objects as they navigate (or are navigated) along a winding virtual path. The VRLAT is easy to administer, demonstrates strong sensitivity and specificity, minimal practice effects, and strong validity, and outperforms traditional paper-and-pencil tests in the prediction of real-world collisions.
A shortened version with a five-minute administration time has many of the desireable psychometric properties of the original full-length task.
