This volume unveils the untold personal narratives behind the scientific study of human language and cognition from a behavioral perspective. Moving beyond the formal record of published research, it captures the passion, debates, failures, and moments of discovery that have shaped this transformative field over the past seventy years and beyond. Through these stories, readers gain a deeper understanding of the human experiences that drive the quest to build a natural science of human behavior.
Structured as a compelling historical narrative, the book traces the evolution of the field from Skinner’s Verbal Behavior to groundbreaking developments in areas such as rule-governed behavior, stimulus equivalence, relational frame theory, and naming theory. Contributors, ranging from foundational figures to contemporary innovators, share candid accounts of intellectual rebellion, collaboration, mentorship, and the challenges of translating complex science into practice. These narratives highlight the pivotal role of global exchange, persistence, and the lived experiences of scientists in advancing the field.
This book is an essential resource for scholars, students, researchers, and practitioners in behavior analysis and psychology, as well as historians and philosophers of science. Its engaging and personal storytelling makes it ideal for graduate and undergraduate courses, while offering invaluable insights for anyone curious about the history of science and the people who shape it.
