Donald A. Norman investigates how the design of modern technology fundamentally alters human cognition and argues for a shift toward human-centered machine development. Drawing on his extensive background in cognitive science and engineering, Norman examines the historical and psychological ways humans utilize tools to extend their mental capabilities. He posits that current technological design often forces human thought to adapt to machine logic, and he proposes a framework for creating systems that align with natural human cognitive processes.

Experts in the field of human-computer interaction frequently cite this work as a foundational text for understanding the intersection of psychology and engineering. Readers often note the accessibility of the prose despite the academic depth of the subject matter.
