100 Things Every Designer Needs to Know About People

What you think people are going to see on your Web page may not be what they do see.

What you think people are going to see on your Web page may not be what they do see. Pattern recognition: The brain is wired to recognize patterns and shapes, often filling in missing information or creating meaning where none exists. This phenomenon, known as pareidolia, explains why we see faces in clouds or objects in random patterns. Selective attention: Our visual system is designed to focus on specific elements while filtering out others. This selective attention can be manipulated through design choices, such as color, contrast, and placement. For example, people tend to notice movement in their peripheral vision, which is why blinking advertisements can be both effective and annoying. Key visual processing facts: The brain processes visual information in parallel, not sequentially Peripheral vision is crucial for understanding context and gist Color perception can vary significantly between individuals and cultures Faces are processed differently and more quickly than other visual stimuli

Short-term memory is limited. Working memory capacity: The average person can only hold about four items in their working memory at a time. This limitation affects how we process and retain information in the short term, influencing everything from user interface design to educational strategies. Long-term memory formation: To move information from short-term to long-term memory, repetition and meaningful association are crucial. The brain creates stronger neural connections when new information is linked to existing knowledge or experiences. This is why analogies and storytelling can be powerful tools for learning and retention. Memory enhancement techniques: Chunking: Grouping information into manageable units Spaced repetition: Reviewing information at increasing intervals Elaborative rehearsal: Connecting new information to existing knowledge Visualization: Creating mental images to represent concepts or data

Attention is selective. Attentional filters: The brain constantly filters incoming information, focusing on what it deems important or novel. This filtering process is influenced by personal relevance, emotional impact, and contextual cues. Designers and marketers can leverage this by creating experiences that stand out from the noise and align with users' interests and goals. Multitasking myth: Despite popular belief, true multitasking is a myth. The brain rapidly switches between tasks rather than processing them simultaneously. This task-switching comes at a cognitive cost, reducing efficiency and increasing the likelihood of errors. Understanding this limitation is crucial for designing interfaces and workflows that minimize cognitive load and maximize focus. Factors that capture attention: Novelty and surprise Personal relevance Emotional content Movement and contrast Narrative structure
