Crows can evaluate visual info twice as fast as mammals
Summary
Recent scientific findings show that crows process visual information at double the speed of mammals. Researchers discovered this by observing how brains accumulate visual evidence during movement-tracking tasks. This reveals significant differences in how avian and primate brains make decisions.
Much of what we know about how a brain makes decisions comes from studying monkeys watching dots. in a task known as a random-dot-motion task, a cloud of flickering specks drifts weakly in one direction while the subject tries to determine whether—and in which direction— it’s moving.
