Psychology of Speed: A Guide to Perceived Performance

Perceived performance refers to how fast or responsive a website or app feels compared to how fast or responsive it is. Factors affecting perceived performance include emotional state, age, complexity of task, input mode, and interface feedback. Optimizing actions people perform most frequently and providing appropriate feedback can improve perceived speed. Attention spans are categorized based on response time, and appropriate loading indicators can be chosen based on wait time. Strategies for preventing sudden page movements and unresponsive pages are also discussed. Design rooted in behavioral psychology can contribute to better performance and user experience.
