The brain may learn about the world the same way some computational models do

New studies support the idea that the brain uses a process similar to a machine-learning approach known as 'self-supervised learning.' This type of machine learning allows computational models to learn about visual scenes based solely on the similarities and differences between them, with no labels or other information.

Why all languages have words for 'this' and 'that'

Researchers have found that languages around the world have words for 'this' and 'that'.
