cocktail party effect
You are constantly filtering conversations you are not hearing.
A 1953 study by Colin Cherry established the cocktail party problem, demonstrating the brain's strong tendency to filter out unattended audio streams.
The original study focused on the inability to recall content from unattended channels, rather than a successful parallel-processing of salient background information.
You are never actually ignoring your surroundings.
Where this comes from
- Study
- Colin Cherry, 1953
- What the check found
- Cherry's 1953 study demonstrated the limitations of attention (the 'filter' model). The ability to maintain awareness of salient information in the background is a nuance added by later researchers like Treisman.
- Confidence
- Solid, with limits
