====Summary====                   
{{$demo.summary}}



====Procedure====  
  - Have participants focus on a primary task, such as counting passes in a ball game video or following a moving object.  
  - While they are concentrating, introduce an unexpected but obvious element into the scene, such as a person in a costume walking through.  
  - After the task, ask participants whether they noticed the unexpected event.  
  - Discuss how attention can filter perception and lead to missing information.

====Variations====
  * Use live demonstrations in a classroom with staged events.  
  * Replace visual tasks with auditory tasks, such as focusing on one conversation while another unusual sound occurs.  
  * Vary the complexity of the primary task to see how it affects attention.



====Safety Precautions====
  * No specific safety risks, but ensure the staged events are safe and non-threatening.  
  * If using a live demonstration, avoid startling participants excessively.




====Questions to Consider====
  * Why do people fail to notice something that is directly in their line of sight? (Because attention has limited capacity and filters incoming information.)  
  * How does attentional control help us in everyday life? (It allows us to focus on important tasks and filter distractions.)  
  * Can inattentional blindness be reduced? (Yes, with practice, training, or by reducing task difficulty, but it cannot be fully eliminated.)  
  * What real-world consequences might inattentional blindness have? (Examples include missing safety warnings, traffic hazards, or important announcements.)
