Neuropsychology of Learning Disabilities

Book excerpt: Building upon earlier attempts to create a scientific basis for subtypes of learning disabili~ties, this volume continues to examine the extent to which various subtyping schemes are valid. Like its predecessor, Neuropsychology of Learning Disabilities: Essentials of Subtype Analysis, it seeks to define such subtypes within an explicitly neuropsychol~ogical framework. Following an insightful over~view of the dimensions and clinical applications of validity to learning disability subtypes, it reports on a wide-ranging series of investigations designed to designate the content, concurrent, predictive, construct, and clinical validity of various subtyping efforts.
