Rats & Tests

From "Smart, Curious, Ticklish. Rats?" by NATALIE ANGIER, New York Times:

In the Georgia study, rats were asked to show their ability to distinguish between tones lasting about 2 seconds, and sounds of about 8 seconds, by pressing one or another lever. If the rat guessed correctly, it was rewarded with a large meal; if it judged incorrectly, it got nothing.

For each trial, the rat could, after hearing the tone, opt to either take the test and press the short or long lever, or poke its nose through a side of the chamber designated the, “I don’t know” option, at which point it would get a tiny snack. During the trials, the rats made clear they knew their audio limits. The closer the tones were to either 2 or 8 seconds, the likelier the rats were to express confidence in their judgment by indicating they wanted to take the lever test and earn their full-course dinner. But as the tones edged into the ambiguous realms of 4 seconds, the rats began opting ever more often for modest but reliable morsels of the clueless option.

Goddamn I love animal science, esp. animal ethology (Lat., lit. "why we do stuff-ology"). I'm going to train rats to write blog posts about rats, and then I'll be out of pseudo-work and finally able to enjoy this giant spinning wheel I built. Joy!
