📚 Quick Study Guide: Understanding Attention
- 🎯 Definition: Attention is the concentration of mental effort on sensory or mental events. It's a limited cognitive resource.
- 🧠 Selective Attention: The ability to focus on one stimulus while ignoring others. Think Cocktail Party Effect.
- 🔍 Divided Attention: The ability to perform multiple tasks at once, requiring attention to be split between them. Often leads to performance decrements.
- ⏱️ Sustained Attention (Vigilance): The ability to maintain attention over an extended period, crucial for tasks like air traffic control.
- 🚧 Attentional Bottleneck: Models (e.g., Broadbent's Filter Model, Treisman's Attenuation Model) describe how much information we can process at once.
- 🔄 Change Blindness: Failure to notice obvious changes in a visual scene.
- 🦍 Inattentional Blindness: Failure to notice an unexpected stimulus that is in plain sight, often due to focus on another task (e.g., the "gorilla" experiment).
- 💡 Automatic vs. Controlled Processing: Automatic processes require little to no conscious effort, while controlled processes require significant attention.
