Study Notes
Cognitive Ergonomics
- Focuses on optimizing human cognitive performance, well-being, and productivity through the design of systems, products, and environments.
- Considers human abilities and limitations, aiming to enhance user experience and reduce errors.
- Significant benefits include improved overall well-being and increased productivity.
Key Cognitive Processes
- Perception: Interpretation of sensory information.
- Attention: Selective focus on stimuli; important for behavior and mental processing.
- Types include selective, divided, alternating, and sustained attention.
- Memory: Ability to encode, store, and recall information; crucial for daily functions and interactions.
- Memory types: sensory, short-term, long-term, declarative, procedural, and episodic memory.
Cognitive Load
- Refers to the amount of mental effort needed for a task.
- The goal of cognitive ergonomics is to minimize cognitive load in design.
Recent Advancements
- Neuroscience research enhances understanding of cognitive processes, informing neurologically compatible designs.
- Applications of AR and VR, alongside AI, allow real-time adaptation to user behavior, lowering cognitive load.

Types of Attention
- Selective Attention: Focusing on one stimuli while ignoring others.
- Divided Attention: Processing multiple stimuli simultaneously (multi-tasking).
- Alternating Attention: Shifting focus between tasks with different demands.
- Sustained Attention: Maintaining focus on a task over time without distractions.
Memory Processes
- Recall: Actively retrieving learned information.
- Recognition: Identifying previously learned material.
- Relearning: Assessing the time saved when relearning material.
Memory Types
- Sensory Memory: Briefly holds sensory information.
- Short-term Memory: Temporary storage for currently processed information.
- Long-term Memory: Storage for information over extended periods.
- Declarative Memory: Recall of facts and events.
- Procedural Memory: Unconscious memory of skills.
- Episodic Memory: Personal experiences linked to specific times and places.
Metacognition
- Involves awareness of one's cognitive processes.
- Helps in monitoring thoughts and adjusting learning strategies, enhancing problem-solving and effective learning.
Mind Mapping and Visualization
- Techniques to visually organize complex information.
- Aid in recognizing relationships and patterns, improving understanding and memory.
Signal Detection Theory (SDT)
- Framework to distinguish between signal (stimulus) and noise (background stimuli).
- Key Components:
- Signal vs. Noise: Every decision includes a target and irrelevant stimuli.
- Outcomes categorized as hit, miss, false alarm, and correct rejection.
