Three Perceptual Processes • Human Factors Guidelines
A Model of Working Memory • Limits of Working Memory • Capacity • Time • Confusability and Similarity • Attention and Similarity
HF Implications of WM Limits • Minimize working memory load • Provide visual echoes • Provide placeholders for sequential tasks • Exploit chunking • Minimize confusability • Avoid unnecessary zeros in codes to be remembered • Consider WM limits in instructions
Basic Mechanisms • Strength • Associations • WM and LTM • Forgetting
Organization of Info in LTM • Schemas and Scripts • Mental Models • Cognitive Maps • LTM Implications for Design • Episodic Memory for Events • Prospective Memory for Future Events
Mental Effort and Resource Demand • Structural Similarity • Confusion • Task Management and Interruptions • Addressing Time-Sharing Overload
