Intended for beginning graduate or advanced undergraduate students, our book Principles of Research in Behavioral Science (4e, Routledge) provides a comprehensive review of research methods used in psychology and related disciplines. It covers topics that are often omitted in other texts including correlational and qualitative research and integrative literature reviews. Basic principles are reviewed for those who need a refresher. The focus is on conceptual issues; statistics are kept to a minimum. Featuring examples from all fields of psychology, the book addresses laboratory and field research. Chapters are written to be used independently, so instructors can pick and choose those that fit their course needs. Reorganized to parallel the steps of the research process, tips on writing reports are also provided. Each chapter features an outline, key terms, a summary, and questions and exercises that integrate chapter topics and put theory into practice. A glossary and an annotated list of readings are included.
