Cognitive limit refers to the maximum amount of information that an individual can process and retain at one time. This concept is often associated with the Miller's Law, which suggests that the average person can hold about seven pieces of information in their working memory. When this limit is exceeded, it can lead to confusion, errors, and difficulty in decision-making. Understanding cognitive limits is important in various fields, including education and user experience design. By recognizing these limits, educators and designers can create more effective learning environments and interfaces that accommodate the natural constraints of human cognition, ultimately enhancing comprehension and usability.
