Sources of error in computerized neuropsychological assessment.
Computerized neuropsychological assessment has integrated slowly into research and practice since the introduction of the personal computer. Though initial integration of technology to the laboratory and clinical setting utilized specialized hardware and software, newer generation assessment tools are integrated with "off-the-shelf" operating systems. Further, neuropsychological assessment is beginning to find Internet-based application for remote assessment. As these applications are more broadly applied, it is essential to understand potential errors that can be created both in test administration and in reaction time measurement due to hardware and software interactions. In this article, user considerations are specifically addressed for resident and Internet-enabled assessment software. Potential hardware and software conflicts are defined and potential remediation is suggested. Computerized assessment is a valuable tool for neuropsychologists as long as it is used responsibly with an understanding of the potential technical complications.
