Book excerpt: Wilson provides a thorough, engaging introduction to the underlying principles of biological psychology in 16 manageable chapters. Going beyond the typical boundaries, Wilson includes cutting-edge research from molecular biology, neuroscience, psychobiology, and neuropsychology to give the reader a more complete--yet accessible--understanding of the biological bases of human behavior. Wilson also offers a special focus on human behavior and physiology. This focus makes the text unique in the market, as most of the competing books emphasize animal models and include only limited human examples. This new text features an outstanding art program, carefully developed to clarify core concepts. Readers will find that each of Wilson's 16 chapters offers current research findings, an excellent use of everyday examples to make difficult concepts understandable, and pedagogy crafted to help students master the material.
