Everyday forgetfulness—missing phone digits, skipping items on a shopping list—stems from the brain's limited working‑memory capacity of about 7±2 chunks, a constraint that can be mitigated by grouping information into meaningful chunks, a principle widely used in UX design.
This article surveys the mathematical modeling of memory and forgetting, tracing the classic Ebbinghaus exponential decay curve, power‑law refinements, the Memory Chain Model, ACT‑R activation equations, and their extensions toward personalized and physiologically informed forgetting models.
The article examines the widespread “knowledge hoarding syndrome”—the habit of buying and bookmarking endless courses and articles without using them—by citing MOOC dropout rates, cognitive‑psychology research, and a simple information‑processing model, then offers concrete steps to break the cycle.
This article introduces a practical "Predictive Learning" method—guess first, verify seriously, adjust prior—explaining how proactive prediction, grounded in Bayesian reasoning, enhances cognition, memory, and decision‑making across any subject.
Drawing on the book “Learning Power Revolution,” this article categorizes four types of carelessness, outlines a five‑module ideal learning system, and reveals how elite Tsinghua students use multi‑layer verification and proactive error‑warning strategies to dramatically reduce simple mistakes.
This article summarizes a cognitive‑psychology book that reveals how the brain’s learning mechanisms—story, emotion, memory, background knowledge, and practice—shape effective thinking and lasting education, offering practical advice for both teachers and learners.
The information processing theory, emerging in the 1950s‑60s, likens human cognition to computer operations, detailing how perception, attention, memory, conceptual knowledge, reasoning, and feedback mechanisms transform sensory input into mental representations and guide behavior, influencing cognitive psychology, education, and HCI.
This article explores essential visual psychology concepts for designers, covering how we observe, read, remember, think, focus, and make decisions, and offers practical design guidelines such as leveraging optical illusions, peripheral vision, pattern recognition, color‑blind accessibility, cultural color meanings, and the proximity principle to create more intuitive user experiences.
The article explains why popular mobile payment platforms like WeChat and Alipay use six‑digit numeric passwords, discussing brute‑force attack complexity, the rapid growth of computing power, human short‑term memory limits, and additional authentication layers that together make six‑digit passwords a practical balance of security and usability.
The article explains how understanding user psychology—such as perception, reading, and memory—can guide industrial design to create more satisfying experiences, improve retention, and increase software activity by aligning design elements with users' mental expectations.
This article explains how an IP smart image library was built to automate pattern creation, outlines the evolution of its generation rules, and shows how aligning implementation and mental models leads to an intuitive interface that satisfies both novice and advanced users.
This article explores how the dual‑process theory of human cognition—System 1’s fast, intuitive thinking and System 2’s slow, analytical reasoning—affects user experience design, offering concrete design principles and a case study of the WeChat "Watch" feature to illustrate practical applications.
The classic Miller’s 7±2 principle, which states that short‑term memory can hold about seven items, offers practical guidelines for UI designers: limit choices, group information hierarchically, chunk long data, and streamline navigation to improve app usability and reduce user error.
The article explains how modular design leverages cognitive psychology—highlighting the brain's limited information‑processing capacity—to simplify complex products, improve user comprehension, and reduce development costs, using real‑world examples from everyday life and product development.
The article explores the concept of mental models as described by Peter Senge, reflecting on how these internal cognitive frameworks shape our interpretation of the world, and discusses personal insights on standardizing human thought processes.
The author shares a personal journey into memory research, reviewing four influential books on mind mapping, right‑brain photographic memory, comprehensive memory systems, and the “memory box” technique, highlighting how visual cues and structured repetition can dramatically improve learning and retention.
This article explains how positioning important information at the beginning and end of a presentation, using focused attention drills, complement‑set memorization, self‑talk, visual aids, and intuitive language can dramatically improve recall and learning efficiency.
The article explains that beyond our conscious awareness lies implicit memory, a hidden form of long‑term memory that influences decisions without us realizing it, illustrated by examples such as anesthetized patients recalling Shakespeare and everyday choices shaped by unnoticed past information.
This article introduces key psychological theories—including cognitive psychology, Gestalt principles, color psychology, and flow state—that interaction designers should understand to create more intuitive, engaging, and effective user experiences.
This article explains how cognitive and visual information processing theories show that minimalist, prototype‑based UI designs reduce mental load, increase user fluency, and dramatically boost conversion rates, supported by real‑world e‑commerce case studies and statistical evidence.
