This book is a unique and comprehensive introduction to psychology. It consists of short modules that keep students engaged with humor, a narrative style, and hands-on activities that facilitate interactive learning and critical thinking. Each stand-alone module focuses on a major topic in psychology, from the brain, sensation, memory, and cognition to human development, personality, social psychology, and clinical psychology. The modular format also allows a deep dive into important topics that have less coverage in other introductory psychology textbooks. This includes cross-cultural psychology, stereotypes and discrimination, evolutionary psychology, sex and gender, climate change, health psychology, and sport psychology. This truly modular format - ideal for both face to face and virtual learning - makes it easy for instructors to customize their readings and assign exactly what they wish to emphasize. The book also contains an abundance of pedagogical features, including numerous hands-on activities and/or group discussion activities, multiple-choice practice quizzes, and an instructor exam bank written by the authors. By covering both classic and contemporary topics, this book will delight students and instructors alike. The modular format also makes this a useful supplementary text for classes in nursing, medicine, social work, policing, and sociology.
