"When my order arrived, I kept wondering how I could've missed something so obvious. The answer? Selective attention - our brain's way of focusing on what seems most important in the moment, while filtering out the rest. Cognitive principles like selective attention shape every user interaction - what people notice, remember, learn, and even the mistakes they make. Apply them thoughtfully, and you can reduce mental effort, guide users' attention, ease recall and retention, and even motivate users."
"Reducing mental effort Cognitive load theory This theory states that our working memory can only handle a limited amount of information at any given time. To avoid cognitive overload, designs must stay within users' natural processing limits. When crafting UX content and layout, you can reduce cognitive load by: Keeping interfaces simple Limiting decision points Using clear, concise copy Breaking complex tasks into manageable steps"
People form early mental models from simple patterns, and those models continue to shape interactions with systems. Cognitive principles are fundamental patterns that guide thinking, learning, memory, and decision-making. Designers can predict and influence user behavior by aligning interfaces with these principles. Selective attention causes users to focus on perceived priorities and miss other details, producing predictable errors. Limiting cognitive load preserves working memory: keep interfaces simple, reduce decision points, use clear concise copy, and break complex tasks into manageable steps. Applying cognitive principles can reduce mental effort, guide attention, improve recall, and motivate users.
