One of the tests that make up the NAB Spatial Module, the NAB Visual Discrimination Test now is available as a stand-alone assessment. The task evaluates deficits in visual perception using stimuli that are not easily verbally encoded. Administration of the assessment is relatively brief and straightforward, incorporating a match-to-target paradigm that is commonly used to measure visual perception.
- Eighteen-item task requires the examinee to match a target visual design from an array of four similar designs.
- Colourful abstract designs maintain examinee engagement.
- A detailed Record Form guides you through the measure, making it quick, efficient, and easily portable for use in a variety of settings.
- Equivalent, parallel forms allow for ease of retesting and reduce the likelihood of practice effects
