Significant new insights and research findings about brain-behavior relationships, neurological disorders, neurodiagnostic issues, and neuropsychological assessment procedures are incorporated into the third edition of _Neuropsychological Assessment_. Preliminary chapters present the principles necessary for a patient-oriented, personalized, hypothesis-testing approach to neuropsychological assessment. The subsequent chapters contain nearly all of the tests and assessment techniques covered in the previous editions plus many additional ones, including newly developed neuropsychological tests, tests from other branches of psychology, research techniques that have only recently been introduced into clinical neuropsychology, tests originating in Europe and elsewhere, and a few measures as yet untried by neuropsychologists. In a reorganization designed to meet current thinking and assessment procedures, tests originally offered in prepackaged batteries are now presented within their appropriate functional domains. For example, individual memory tests -- whether developed singly or for use in a commercial battery -- are discussed in the chapter on memory tests, while a new chapter deals with memory batteries, questionnaires, and inventories. A separate chapter reviews prepackaged and commercial test batteries used for general-purpose neuropsychological assessment, but the individual tests from these batteries are treated elsewhere according to the salient functions they examine. Following chapters on observational measurement techniques and on measures of personality and emotional status, the concluding chapter presents an array of techniques that have been used to identify motivational problems and malingering.
