In most discussions about intellectual development and assessment, the focus is on children. Rarely do assessment practitioners focus on cognitive impairments and other intellectual development issues pertaining to adults. On the cutting edge of assessment issues, Gregory's book includes adults as his primary focus, attempting to answer such important questions as: When is an intellectual assessment appropriate? How do professional and ethical standards inform the practice of assessment? This book responds to a void in the field of assessment following the recent release of the WAIS-III (Wechsler Adult Scale) test, which is now the cornerstone for adult intellectual assessment. Until the publication of this book, there has been no extensive information available about the effective use and interpretation of this and other important assessment tests. This single volume contains comprehensive information, including test norms and standards for effective use of the WAIS-III and many other tests (mental status, attention/concentration, sensory/perceptual, psychomotor, memory, language, drawing, higher cognitive functions, intelligence). Readers will understand the context of psychological assessment, the importance of personal background and mental status in assessment, and the shifting professional standards and ethics of today.
