{ "item_title" : "From Cognitive Load to Cognitive Distance", "item_author" : [" Izaias Cavalcanti "], "item_description" : "People can finish a task and still not understand what just happened.For decades, usability and accessibility have been judged by effort: clicks, time, memory load. Yet people often fail not because a system asks too much of them, but because its logic is foreign to them. They pass every usability test and still call the help line. They meet every accessibility standard and still feel lost.This book introduces cognitive distance: the mismatch between the conceptual structure a system requires and the mental model a person actually builds while using it. Distance is relational, it accumulates across an interaction, and it can be high even when effort is low. That is why compliant, efficient systems still leave people behind.Drawing on Human-Computer Interaction, cognitive psychology and public administration research, and on cases from healthcare portals, government services, banking and AI products, the book shows: why task success can hide failed understandinghow systems quietly hand interpretive work to users, from file conversions to unexplained status codeshow to measure distance with the Cognitive Distance Index, and what the Everyday Services Study founda practical framework for diagnosing and closing distance across a product's lifecycleWritten for UX designers, researchers, product teams, accessibility specialists and anyone who builds public digital services, From Cognitive Load to Cognitive Distance offers a new language for an old problem, and a way to design systems people can understand, not merely operate.", "item_img_path" : "https://covers4.booksamillion.com/covers/bam/9/79/816/001/9798160019079_b.jpg", "price_data" : { "retail_price" : "19.99", "online_price" : "19.99", "our_price" : "19.99", "club_price" : "19.99", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
