      function: the Virtual Library Task.

AB  - Virtual reality (VR) assessment paradigms have the potential to address the 
      limited ecological validity of pen and paper measures of executive function (EF) 
      and the pragmatic and reliability issues associated with functional measures. To 
      investigate the ecological validity and construct validity of a newly developed 
      VR measure of EF, the Virtual Library Task (VLT); a real life analogous task--the 
      Real Library Task (RLT); and five neuropsychological measures of EF were 
      administered to 30 patients with traumatic brain injury (TBI) and 30 healthy 
      Controls. Significant others for each participant also completed the Dysexecutive 
      Questionnaire (DEX), which is a behavioral rating scale of everyday EF. 
      Performances on the VLT and the RLT were significantly positively correlated 
      indicating that VR performance is similar to real world performance. The TBI 
      group performed significantly worse than the Control group on the VLT and the 
      Modified Six Elements Test (MSET) but the other four neuropsychological measures 
      of EF failed to differentiate the groups. Both the MSET and the VLT significantly 
      predicted everyday EF suggesting that they are both ecologically valid tools for 
      the assessment of EF. The VLT has the advantage over the MSET of providing 
      objective measurement of individual components of EF.
