Department of Psychology: Faculty Publications

Although deficits in visual attention are often postulated as an important component of many declines in cognitive processing and functional outcomes in older adults, surprisingly little emphasis has been placed on evaluating psychometric instruments with which individual differences in visual attention ability can be assessed. This article reports the development and beginning psychometric evaluation of DriverScan, a change detection measure of attentional search for older adults. A constrained graded response model is used to approximate response speed and accuracy with categories of immediate, delayed, or no response. DriverScan items are shown to have excellent reliability over the studied sample, and …
