“In effect, we discovered how the brain’s dictionary is organized,” said Just, the D.O. Hebb Professor of Psychology and director of the Center for Cognitive Brain Imaging. “It isn’t alphabetical or ordered by the sizes of objects or their colors. It’s through the three basic features that the brain uses to define common nouns like apartment, hammer and carrot.” … The three codes or factors concern basic human fundamentals:
- how you physically interact with the object (how you hold it, kick it, twist it, etc.);
- how it is related to eating (biting, sipping, tasting, swallowing); and
- how it is related to shelter or enclosure.
The three factors, each coded in three to five different locations in the brain, were found by a computer algorithm that searched for commonalities among brain areas in how participants responded to 60 different nouns describing physical objects.
