This book has been authored by two senior figures in clinical neuropsychology. There has long been considerable debate over localization. How widespread is it? Are some functions more localized than others? By the mid-20th century, a formidable amount of evidence seemed to strongly support the ""modularity hypothesis"" that psychological functions such as language and memory reside in specific neuroanatomical areas.Within neuropsychology, localization refers to the relationship between the anatomical structures of the brain and their corresponding psychological or behavioral function. The book's ""big picture"" perspective on a long running debate will usefully counterbalance current research that emphasizes imaging studies to the exclusion of other useful techniques.
