While this study focused on numerical quantity, similar mechanisms may also underlie other quantitative concepts, such as size and time. Investigating whether the brain represents these concepts in a ...

Waltham, Mass. – A Brandeis University researcher has shown that an African grey parrot with a walnut-sized brain understands a numerical concept akin to zero – an abstract notion that humans don't ...

Although the actual number of items differs, the brain exhibits similar activity patterns when focusing on an extra-small (XS) quantity among packs with few items (small set) and when focusing on an ...

Behavioural studies have revealed that the processing and representation of numerical magnitude are qualitatively similar across species and across human development. Reliable effects such as the ...

A Brandeis Univesity researcher has shown that an African grey parrot with a walnut-sized brain understands a zero-like concept -- an abstract notion that humans don't typically understand until age 3 ...
