Abstract:
The assessment of executive functions is an integral task of neuropsychological assessment. Traditional measures of executive function are often based on hypothetical constructs that may have little relevance to real-world behaviours. In fact, some traditional tests utilised today were not originally developed for clinical use. Recently, researchers have been arguing for a new generation of "function-led" neuropsychological assessments that are developed from directly observable everyday behaviours. Although virtual environments (VEs) have been presented as potential aides in enhancing ecological validity, many were modelled on construct-driven approaches found in traditional assessments. In the current paper, we review construct-driven and function-led VE-based neuropsychological assessments of executive functions. Overall, function-led VEs best represent the sorts of tasks needed for enhanced ecological validity and prediction of real-world functioning.
