The Scientific Foundation Of Neuropsychological Assessment

Neuropsychology is a specialized branch of psychology which focuses on the relationship between the brain and human functions including cognition, behaviour, and emotion. With an emphasis on a scientific approach which includes analysing quantitative data, neuropsychology follows an information processing approach to brain activity using standard assessments to evaluate various mental functions. This book examines the standardized battery of tests in neuropsychology, with a particular focus on forensic applications of these tests, suggesting that a united theory of assessment needs to be established. Bringing together multiple articles related to forensic neuropsychology, this book offers an exploration of the neurological and psychometric theoretical basis for standardized batteries as well as a comparison between flexible and standardized batteries. Ultimately, it is argued that a standardized battery of tests need to be used and explains the justification for the reliability of this approach, especially in relation to expert witness testimony. While doing this, formal procedures, including advanced mathematical procedures such as formulas and decision tree algorithms, are presented to be utilized in assessments. With its thorough examination of the theoretical and practical applications of a standardized battery in neuropsychological assessment, this book will prove helpful to clinical practitioners and attorneys using assessment for their cases. Provides a unified theoretical basis for a standardized neuropsychological assessment battery Shows the justification for using neuropsychological assessment in forensic applications Offers practical examples which can be used to create a standardized assessment battery

With the emergence of clinical neuropsychology as one of the fastest growing specialties in psychology comes the need for current and future practitioners to stay abreast of the most recent research. A number of professional journals more than adequately meet this need. But, there is also a need to stay up to date on the current thinking about important problems. Drawing upon the expertise of leaders in the field, the editors' intent in this book was to provide the practitioner with a source for discussions of topics that are vital to their ongoing development as clinical neuropsychologists but that generally are not addressed in the literature to any great degree.

In the last decade, neuropsychology has grown from a small subspecialty to a major component in the practice of clinical and medical psychology. This growth has been caused by advances in psychological testing (such as the Halstead-Reitan neuropsychological battery, as discussed in Chapter 5) that have made evaluation techniques in the field available to a wider audience, by advances in neuroradiol ogy and related medical areas that have enabled us to better understand the struc ture and function of the brain in living individuals without significant potential harm to those individuals, and by increased interest by psychologists and other scientists in the role that the brain plays in determining behavior. Many disorders that were believed by many to be caused purely by learning or environment have been shown to relate, at least in some cases, to brain dysfunction or damage. With the growth of the field, there has been increased interest in the work of neuropsychologists by many who are not in the field.

Evidence-based practice has become the benchmark for quality in healthcare and builds on rules of evidence that have been developed in psychology and other health-care disciplines over many decades. This volume aims to provide clinical neuropsychologists with a practical and approachable reference for skills in evidence-based practice to improve the scientific status of patient care. The core skills involve techniques in critical appraisal of published diagnostic-validity or treatment studies. Critical appraisal skills assist any clinician to evaluate the scientific status of any published study, to identify the patient-relevance of studies with good scientific status, and to calculate individual patient-probability estimates of diagnosis or treatment outcome to guide practice. Initial chapters in this volume review fundamental concepts of construct validity relevant to the assessment of psychopathology and cognitive abilities in neuropsychological populations. These chapters also summarize exciting contemporary development in the theories of personality and psychopathology, and cognitive ability, showing a convergence of theoretical and clinical research to guide clinical practice. Conceptual skills in interpreting construct validity of neuropsychological tests are described in detail in this volume. In addition, a non-mathematical description of the concepts of test score reliability and the neglected topic of interval estimation for individual assessment is provided. As an extension of the concepts of reliability, reliable change indexes are reviewed and the implication of impact on evidence-based practice of test scores reliability and reliable change are described to guide clinicians in their interpretation of test results on single or repeated assessments. Written by some of the foremost experts in the field of clinical neuropsychology and with practical and concrete examples throughout, this volume shows how evidence-based practice is enhanced by reference to good theory, strong construct validity, and better test score reliability.

Neuropsychological assessment is a difficult and complicated process. Often, experienced clinicians as well as trainees and students gloss over fundamental problems or fail to consider potential sources of error. Since formal test data on the surface appear unambiguous and objective, they may fall into the habit of overemphasizing tests and their scores and underemphasizing all the factors that affect the validity, reliability, and interpretability of test data. But interpretation is far from straightforward, and a pragmatic application of assessment results requires attention to a multitude of issues. This long-awaited, updated, and greatly expanded second edition of the Clinician's Guide to Neuropsychological Assessment, like the first, focuses on the clinical practice of neuropsychology. Orienting readers to the entire multitude of issues, it guides them step by step through evaluation and helps them avoid common misconceptions, mistakes, and methodological pitfalls. It is divided into three sections: fundamental elements of the assessment process; special issues, settings, and populations; and new approaches and methodologies. The authors, all of whom are actively engaged in the clinical practice of neuropsychological assessment, as well as in teaching and research, do an outstanding job of integrating the academic and the practical. The Clinician's Guide to Neuropsychological Assessment, Second Edition will be welcomed as a text for graduate courses but also as an invaluable hands-on handbook for interns, postdoctoral fellows, and experienced neuropsychologists alike. No other book offers its combination of breadth across batteries and approaches, depth, and practicality.

Minority and cross-cultural psychology is more relevant now than ever in our diverse world. Given the dramatic local and global changes occurring daily with regard to demographics, population changes, and immigration issues, minority and cross-cultural psychology is fast becoming a respected and critical area of scientific study. Pair that with the fact that people of all cultures and racial groups are living longer and experiencing age-related diseases and disorders, one can easily see the need for additional work on issues related to neuropsychological assessment. This new edition brings to the forefront recent developments by seasoned experts in the field. They offer up their newest projects in minority and cross-cultural aspects of neuropsychological assessment and are joined by new, up-and-coming professionals across a wide array of disciplines including psychology, medicine, and neuropsychology. Like the first edition, this updated collection sheds light on the ever-growing need for adequate neuropsychological assessment to a wider subset of individuals, crossing many cultural and minority barriers in the process. Continuously pushing the boundaries of neuropsychological assessment, this collection is essential reading for cognitive and clinical psychologists, and neuropsychologists, and a model text for advanced courses dealing with minority and cross-cultural issues.
