This two-volume set contains over 250 articles of varying lengths dealing with all aspects of human intelligence.

Argues that a significant part of the gap between rich and poor countries is due to differences in national intelligence.

According to the CDC “about one in six, or about 15%, of children aged 3 through 17 years have one or more developmental disabilities,” such as ADHD, autism spectrum disorders, cerebral palsy, intellectual disability, and learning disability. Intellectual disorders are characterized by significant limitations in both intellectual functioning and in adaptive behavior, which covers many everyday social and practical skills, impacting learning, reasoning, problem solving, and other cognitive processes. These disabilities originate before the age of 18 and continue across the life span. Developmental disorders are chronic disabilities that can be cognitive or physical or both. The disabilities appear before the age of 22 and are likely to progress across the lifespan. Some developmental disorders are largely physical issues, such as cerebral palsy or epilepsy. Some individuals may have a disorder that includes a physical and intellectual disability; for example, Down syndrome or fetal alcohol syndrome. Intellectual and developmental disorders are significant and growing issues that are studied across a number of disciplines. The SAGE Encyclopedia of Intellectual and Developmental Disorders is aimed at students interested in psychology, counseling, education, social work, psychiatry, health sciences, and more. This encyclopedia will provide an in-depth look at a wide range of disorders, alongside interventions, the latest research translated for an undergraduate audience, historical context, and assessment tools for higher-level students. We will take a truly interdisciplinary approach by also covering sociocultural viewpoints, policy implications, educational applications, ethical issues, and more.

It's hard to conceive of a topic of more broad and personal interest than the study of the mind. In addition to its traditional investigation by the disciplines of psychology, psychiatry, and neuroscience, the mind has also been a focus of study in the fields of philosophy, economics, anthropology, linguistics, computer science, molecular biology, education, and literature. In all these approaches, there is an almost universal fascination with how the mind works and how it affects our lives and our behavior. Studies of the mind and brain have crossed many exciting thresholds in recent years, and the study of mind now represents a thoroughly cross-disciplinary effort. Researchers from a wide range of disciplines seek answers to such questions as: What is mind? How does it operate? What is consciousness? This encyclopedia brings together scholars from the entire range of mind-related academic disciplines from across the arts and humanities, social sciences, life sciences, and computer science and engineering to explore the multidimensional nature of the human mind.
