Study: Rats Weigh Cost and Benefit

Rats, like humans, contemplate problems by carefully weighing the costs and benefits of a situation before making decisions, according to a new study on Wistar rats, a rodent developed for research.

The study is the first to demonstrate that a non-human animal creates a desired ratio, or standard, to decide between options requiring varying levels of effort and that yield different rewards.
