A revealing insider’s account of the power—and limitations—of functional MRIThe ability to read minds has long been a fascination of science fiction, but revolutionary new brain-imaging methods are bringing it closer to scientific reality. The New Mind Readers provides a compelling look at the origins, development, and future of these extraordinary tools, revealing how they are increasingly being used to decode our thoughts and experiences—and how this raises sometimes troubling questions about their application in domains such as marketing, politics, and the law.Russell Poldrack takes readers on a journey of scientific discovery, telling the stories of the visionaries behind these breakthroughs. Along the way, he gives an insider’s perspective on what is perhaps the single most important technology in cognitive neuroscience today—functional magnetic resonance imaging, or fMRI, which is providing astonishing new insights into the contents and workings of the mind. He highlights both the amazing power and major limitations of these techniques and describes how applications outside the lab often exceed the bounds of responsible science. Poldrack also details the unique and sometimes disorienting experience of having his own brain scanned more than a hundred times as part of a landmark study of how human brain function changes over time.Written by one of the world’s leading pioneers in the field, The New Mind Readers cuts through the hype and misperceptions surrounding these emerging new methods, offering needed perspective on what they can and cannot do—and demonstrating how they can provide new answers to age-old questions about the nature of consciousness and what it means to be human.

An essential introduction to statistics for students of psychology and the social sciencesStatistical thinking is increasingly essential to understanding our complex world and making informed decisions based on uncertain data. This incisive undergraduate textbook introduces students to the main ideas of statistics in a way that focuses on deep comprehension rather than rote application or mathematical immersion. The presentation of statistical concepts is thoroughly modern, sharing cutting-edge ideas from the fields of machine learning and data science that help students effectively use statistical methods to ask questions about data. Statistical Thinking provides the tools to describe complex patterns that emerge from data and to make accurate predictions and decisions based on data. Introduces statistics from a uniquely modern standpoint, helping students to use the basic ideas of statistics to analyze real data Presents a model of statistics that ties together a broad range of statistical techniques that can be used to answer many different kinds of questions Explains how to use statistics to generate reproducible findings and avoid common mistakes in statistical practice Includes a wealth of examples using real-world data Accompanied by computer code in R and in Python—freely available online—that enables students to see how each example is generated and to code their own analyses

The neuroscience of why bad habits are so hard to break—and how evidence-based strategies can help us change our behavior more effectivelyWe all have habits we’d like to break, but for many of us it can be nearly impossible to do so. There is a good reason for this: the brain is a habit-building machine. In Hard to Break, leading neuroscientist Russell Poldrack provides an engaging and authoritative account of the science of how habits are built in the brain, why they are so hard to break, and how evidence-based strategies may help us change unwanted behaviors.Hard to Break offers a clear-eyed tour of what neuroscience tells us about habit change and debunks “easy fixes” that aren’t backed by science. It explains how dopamine is essential for building habits and how the battle between habits and intentional goal-directed behaviors reflects a competition between different brain systems. Along the way, we learn how cues trigger habits; why we should make rules, not decisions; how the stimuli of the modern world hijack the brain’s habit machinery and lead to drug abuse and other addictions; and how neuroscience may one day enable us to hack our habits. Shifting from the individual to society, the book also discusses the massive habit changes that will be needed to address the biggest challenges of our time.Moving beyond the hype to offer a deeper understanding of the biology of habits in the brain, Hard to Break reveals how we might be able to make the changes we desire—and why we should have greater empathy with ourselves and others who struggle to do so.
