Intelligence and the Brain

ABOUT Dennis Garlick

Dennis Garlick
Dennis Garlick received his Ph.D. in psychology from the University of Sydney in 2003. His Ph.D. focused on using the recent advances in the brain sciences to provide a new approach to explaining human intelligence. This approach was accepted for publication in The Psychological Review, of More...


Presenting a breakthrough new explanation of human intelligence—one rigorously based on the latest scientific discoveries—this book turns the corner and finally provides a resolution to the hot debate over intelligence. Intelligence and the Brain does this by rejecting some of the most common beliefs about intelligence, including that intelligence should be defined by behavior or that intelligence is just memory. Instead, it argues that intelligence reflects the ability to understand. It then uses recent scientific findings about the brain to show how changes in the brain lead to understanding. Readers will find that this book contains many revelations that will profoundly change their perception of how their own brain works.

This book will also explore the startling implication of a "sensitive period" for developing intelligence, arguing that children can learn differently to adults. It will also refute common misconceptions about the brain, including the idea that the first five years of life are the most critical and having more neurons and connections are better. It turns out that late childhood can be the most important for future success and having fewer neurons and connections can be better than more!

It’s all here… for every caring parent, educator, and general reader interested in how the brain works, why people differ in intelligence, and how a child can be a genius.

In this book, I challenge some of the fundamental assumptions that psychologists make about intelligence. By rejecting these assumptions, I show how findings from psychology and recent brain science can be used to provide a new explanation of human intelligence. This explanation has important implications for childhood education, as well as understanding just how our brains work.

Intelligence and the Brain is a fascinating and important work that offers new information about intelligence and, just as important, makes it available to the public at large in a digestible form. Dennis Garlick’s extremely well-written book will provide much to ponder for experts and for anyone with an interest in the latest research on intelligence and genius.”

“In this highly readable yet scientifically grounded book, Garlick takes the increasingly complex notion of intelligence and makes it simple again—directly relating the concept to the questions that most concern us as students, parents, and educators.”
—James W. Stigler, Professor of Psychology, University of California, Los Angeles

“If you are curious about IQ, this book is for you. It has everything that you wanted to know about IQ, but were afraid to ask.”
