Language and communication problems have long figured prominently in the definition of mental retardation. Volume 27 of the International Review of Research in Mental Retardation focuses exclusively on these language and communication issues. The pace of research on language learning and use in mental retardation has increased in recent years and taken new direction. This revitalization has been fueled by three factors: 1) advances in genetic technologies allowing investigation of the behavioral phenotypes of well-defined syndromes, 2) an increased emphasis on maximizing abilities of individuals with mental retardation to live and succeed in a broader range of contexts and settings, and 3) theoretical debates concerning the mechanisms of language development and the nature of the human mind. Contents in Language and Communication in Mental Retardation include syndromes (e.g., Down syndrome, Williams syndrome), domains of language skill (e.g., reading), and intervention strategies. - Contains the most current research on genetic syndromes, including Williams syndrome, Down syndrome, and fragile X syndrome - Outlines the most current research on language and communication intervention for persons with mental retardation - Authors consider the implications of the research reviewed for both theory and clinical practice - Authors bring state-of-the-art knowledge of cognitive science, developmental science, linguistic, and behavioral genetics to bear on important questions about language and mental retardation - Includes new research on long-studied conditions (e.g., Down syndrome) and disorders that are of only recent interest to child language researchers (e.g., fetal alcohol syndrome) - Includes a consideration of nonverbal, as well as verbal, communication

This book celebrates two triumphs in modern psychology: the successful development and application of a solid measure of general intelligence; and the personal courage and skills of the man who made this possible - Arthur R. Jensen from Berkeley University. The volume traces the history of intelligence from the early 19th century approaches, to the most recent analyses of the hierarchical structure of cognitive abilities, and documents the transition from a hopelessly confused concept of intelligence to the development of an objective measure of psychometric g. The contributions illustrate the impressive power g has with respect to predicting educational achievement, getting an attractive job, or social stratification. The book is divided into six parts as follows: Part I presents the most recent higher-stream analysis of cognitive abilities, Part II deals with biological aspects of g, such as research on brain imaging, glucose uptake, working memory, reaction time, inspection time, and other biological correlates, and concludes with the latest findings in g-related molecular genetics. Part III addresses demographic aspects of g, such as geographic-, race-, and sex-differences, and introduces differential psychological aspects as well. Part IV concentrates on the g nexus, and relates such highly diverse topics as sociology, genius, retardation, training, education, jobs, and crime to g. Part V contains chapters critical of research on g and its genetic relationship, and also presents a rejoinder. Part VI looks at one of the greatest contemporary psychologists, Professor Emeritus Arthur R. Jensen as teacher and mentor.
