"Some readers of this book will be interested in earning the credential of Board-Certified Behavior Analyst (BCBA). This credential is granted by the Behavior Analysis Certification Board (BACB) and it is the gold-standard credential of practicing and applied behavior analysts. The BACB's Fifth Edition Task List outlines the Foundational principles and concepts that students must master before beginning an internship as a behavior analyst, and before earning the BCBA credential. The Appendix of this textbook provides the BACB's list of Foundations and indicates the chapter in which each topic is discussed. This book discusses many different categories of human behavior. Behavior analysts and psychologists are asked to help people who suffer from a myriad of difficulties. This includes anxiety, depression, and post-traumatic stress disorder. So that students will have the opportunity to see the utility of behavior analysis in the treatment of these disorders, this book will discuss them. Examples will be provided. If you believe an unexpected encounter with descriptions, or visual depictions of these disorders would be unnecessarily stressful for you, we recommend that you share your concerns with your instructor. They will take care to let you know in advance where these sensitive topics are discussed in the book, and in lectures."--
