Study Notes
Inattentional Blindness
- Inattentional blindness refers to the phenomenon where individuals fail to notice an unexpected stimulus in their visual field when focusing on a different task.
- This cognitive lapse occurs even when the object is in plain sight, highlighting limitations in attention and awareness.
Simons & Chabris Study Findings
- Approximately 50% of participants miss the gorilla when watching a video focused on counting basketball passes.
- A significant disconnect between intuition and actual awareness can be seen in similar experiments.
Change Blindness in Real Life
- Change blindness involves failing to notice substantial changes in a visual scene, often due to shifts in attention or visual memory.
- Everyday examples include failing to recognize changes in the layout of a room or modifications in a person's appearance after a brief distraction.
Expectations vs. Reality
- Around 70% of people predict they would notice the gorilla, but in reality, many fail to do so, demonstrating a disparity between expectations and outcomes in attentional awareness.
Expertise and Detection
- Familiarity with a task tends to increase the likelihood of detecting changes in scenes, as relevant knowledge enhances attentional focus and processing efficiency.
- Individuals with experience in a specific environment are more adept at recognizing inconsistencies or alterations.
