No feature of the mind is as important, controversial, and mysterious as intelligence. It is the epitome of brain function, and it has a powerful influence on success in life. And thanks to decades of research, we are closer than ever before to understanding it. Now in The Intelligent Brain, taught by one of the world's foremost researchers on intelligence, Professor Richard J. Haier of the University of California, Irvine, you'll trace the fascinating history of intelligence testing and its leading thinkers, as well as what brain imaging studies and the most recent research findings reveal about this most complex of human phenomena.
The Intelligent Brain
Plunge into a myriad of thought-provoking issues with a pioneer professor and researcher in psychology to better understand what intelligence is and how it works.
Overview
About
Dr. Richard J. Haier is Professor Emeritus in the School of Medicine at the University of California, Irvine, where he has been teaching and conducting research since 1984. He earned his B.A. in Psychology from the State University of New York at Buffalo, and his Ph.D. in Psychology from Johns Hopkins University. Before his appointment at Irvine he was on the faculty of Brown University's Alpert Medical School. Professor Haier's main research interest is the structural and functional neuroanatomy of higher cognitive processes, especially intelligence. In 1988, he and his colleagues conducted the first modern functional brain imaging study of intelligence with positron emission tomography (PET) and proposed a hypothesis linking good performance on an intelligence test to efficient brain function. Professor Haier's more recent research with magnetic resonance imaging (MRI) has identified specific brain areas where gray and white matter features correlate to the g factor of intelligence and other intelligence factors. In 2012, he received the Distinguished Contributor Award from the International Society for Intelligence Research. In addition to his many professional publications, Professor Haier's research has been featured on NOVA scienceNOW, NPR, CNN, and CBS Sunday Morning, and in numerous newspaper and magazine articles.

01: What Is Intelligence?
Probe the nature of intelligence by looking first at the phenomenon of savants-individuals who excel at a narrow mental skill. Does this qualify as intelligence? Examine how intelligence is defined, and explore its connection to IQ and a variable called g, which is the conjectured general factor of intelligence....

02: Assessing Intelligence
What does an IQ test measure? Study the history of intelligence tests, including the Stanford-Binet test and the Wechsler Adult Intelligence Scale. Consider typical questions used to measure intelligence, and learn how they are designed to avoid bias. Also look at the SAT for college admission....

03: General Intelligence in Everyday Life
Survey the importance of intelligence in 10 areas of everyday life, from school success to managing money to making medical decisions. What does the g factor predict about the ability to cope in these situations? Finally, consider the implications of such predictions for public policy....

04: To g or Not to g-Is That the Question?
Analyze a model of intelligence that incorporates two special factors: fluid intelligence and crystallized intelligence. Then explore alternatives to the g concept, including Robert Sternberg's theory of practical intelligence and Howard Gardner's theory of multiple intelligences. What is the evidence for these ideas?...

05: Intelligence and Genius over the Life Span
Follow the careers of geniuses throughout their lives in three classic studies that began in California in the 1920s, Scotland in the 1930s, and Baltimore in the 1970s. Each study started when the test subjects were children, testing their mental abilities and successes at various intervals....

06: Early Childhood Experience and Intelligence
Do early childhood experiences affect intelligence? Look at the value of compensatory education, which was evaluated in what may be the most controversial article in the history of psychology. Then examine the impact of environmental elements, such as culture, birth order, and family size....

07: Genes and Intelligence
Are there intelligence genes? Delve into the connection between genes and intellectual capacity, focusing on the search for relevant genes and environmental triggers that may govern gene expression. Also examine the history of intelligence research on identical twins, particularly those reared apart....

08: Can We See Intelligence in the Brain?
Brain imaging technology may be the most important development in intelligence research in the last 40 years. Explore positron emission tomography, or PET, which highlights areas of the brain that are working hardest. Learn that these data correlate in an unexpected way with intelligence....

09: What Brain Imaging Reveals about Intelligence
Turn to magnetic resonance imaging, or MRI, a technique that can measure brain structure and changing brain activity. Among other findings, MRI scans suggest that men and women may have different brain areas related to the g factor. Also investigate a new brain imaging technology called magneto-encephalogram, or MEG....

10: Intelligence and the Brains of Children
Examine research about intelligence and the brains of children and adolescents. Focus on three questions: What aspects of brain development are related to intelligence? Are these developmental factors essentially the same for everyone? Is there a critical period when these factors can be influenced?...
29 min
11: Sex and Intelligence
Survey average differences between the sexes in specific mental abilities, such as verbal fluency, fine motor skills, and mathematical and scientific reasoning. Do different performances in these spheres relate to sex differences in the brain? Do these differences help explain the disparity of men and women in certain professions?...

12: Race and Intelligence
Tests such as the SAT show a persistent performance gap connected to race. This is one of the most volatile issues in the social sciences. Use the information developed in the course so far to analyze the issues and possible causes and remedies for closing the gap....

13: Are We Really Getting Smarter?
Delve into the controversy over the Flynn effect, named for psychologist James R. Flynn, who was one of the first to study the phenomenon of worldwide rising IQ scores. Is each generation really smarter than the last? If so, does this trend disprove a major role for genetics in intelligence?...

14: The Mind in Milliseconds
Scores on intelligence tests are only meaningful compared to those of other people. In this lecture, explore a simple and easy way to estimate intelligence in absolute terms. Also, learn about the concept of "mental chronometry" to measure intelligence as proposed by the prolific and controversial researcher, Arthur Jensen of the University of California, Berkeley....
