Psychology is shaped by a rich history of ideas, debates and discoveries that continue to influence the discipline today. Historical and Conceptual Issues in Psychology explores the key historical, philosophical and scientific developments that have shaped modern psychology, helping students understand how the field has evolved and why its foundational questions remain relevant. By connecting historical perspectives with contemporary issues, the text encourages a deeper appreciation of psychology as both a science and a way of understanding human behaviour. Drawing on original sources, influential thinkers and real-world examples, this resource examines major developments in psychology, philosophy and science from ancient Greece to the present day. Updated to reflect current research and debates, including the replication crisis and the growing importance of open science practices, it helps students develop critical-thinking skills and engage thoughtfully with the conceptual foundations of psychological knowledge. Who It's For Ideal for undergraduate and postgraduate students studying psychology and related disciplines who want to understand the historical, conceptual and philosophical foundations of psychological science.
