title: The role of processing speed in the Brief Visuospatial Memory Test - revised.
abstract: The Brief Visuospatial Memory Test - Revised (BVMT-R) is a commonly used, commercialized, assessment tool to measure visuospatial learning and memory abilities across research and clinical settings. In this study we evaluated the influence of processing speed and executive functioning on BVMT-R learning, memory, and percent retention scores. A total of 141 cognitively healthy older adults completed the BVMT-R along with measures of visuoconstructional abilities (BVMT-R copy), speeded processing (Symbol Digit Modalities Test-oral), and executive function (FAS). After controlling for age and visuoconstructional abilities, hierarchical regression models showed that the processing speed measure was a unique predictor of both BVMT-R learning and memory performances, while the executive function measure was not. The visuoconstructional measure was the only unique predictor of BVMT-R percent retention. The findings suggest that, when interpreting the BVMT-R learning and memory scores of patients who exhibit speeded processing deficits, the impact of slowed processing speed on performance should be considered.
