Summary

This chapter considers the role of neuropsychology in the diagnostic process. It covers who can undertake a neuropsychological assessment, when to undertake an assessment, and some of the assumptions underlying neuropsychological assesssment. Basic psychometrics are covered, using the premise that undertanding a few basic concepts is sufficient for most practioners as more complex ideas are developed from these basics. This includes the normal distribution, different types of average, the standard deviation, and the correlation. Next, the relationship between different tyes of metrics is discussed, focusing on IQ/Index scores, T-scores, scaled scores, and percentiles.
