Book excerpt: Introductory Psychology in Modules: Understanding Our Heads, Hearts, and Hands is a unique and comprehensive textbook that offers an accessible, engaging introduction to the key topics of psychology through thirty-six modules that facilitate more focused, interactive learning. Each of the thirty-six modules features an essay on a specific psychology topic--including memory and cognition, human development, clinical psychology, and applied psychology--that stimulate focused critical thinking. Augmenting the essays are supplementary hands-on activities and group discussion proposals, and the modules conclude with multiple-choice practice quizzes for students. These, along with the heavy use of anecdotes, will engage students in active, participatory learning and encourage them to understand and interact with the content of the essays. The modular format allows for instructors to personalize the order of topics covered, as well as skip certain topics and custom-build their own courses on introductory psychology. By covering the classic theories, research, and contemporary findings that every student in psychology should study in digestible, focused modules, Introductory Psychology in Modules is an essential core textbook for all students taking introductory psychology courses. Additionally, the specified modular format allows for this text to be used for supplementary reading where critical thinking is required to aid students in related areas, including nursing, medicine, social work, policing, and sociology.
