Headspace: can our brains get full?

The Conversation · · 808 words · By Michelle Spear
Cognitive Science/Memory Function

The article discusses the nature of human memory, arguing that memory is not a perfect recording device but rather an active process of selection and reconstruction. It explains that the feeling of having a 'full' brain is a misunderstanding of cognitive function, as the brain filters and reorganizes information rather than storing it like a fixed file system. Ultimately, memory recall depends on reinforcement and attention, rather than simply being a perfect retrieval of past events.

“Instead, the brain relies on selection.”
SINGLE SOURCE
The web search results discuss how the brain processes information based on likelihood or differing inputs (e.g., 'Neuroscientists think it bets on what’s the most likely version of reality' or 'Autistic brains take in information differently'), suggesting reliance on selection, but no single source explicitly states 'the brain relies on selection' as a general principle confirmed by multiple independent sources.
