...lsive choices: preferring small but immediate food rewards even when waiting leads to more food over the same time interval. Why would evolution engineer animals to choose smaller benefits? The traditional answer is that delay reduces, or discounts, value in the same way that $10 today is worth more than $...

At the beginning of a session, both rewards were delivered immediately after the choice was made, but the delivery of a large reward was increasingly delayed as the session progressed. At first, pigeons preferred the large reward, but once the preceding delay exceeded a critical threshold of d...

Love's all in the brain: fMRI study shows strong, lateralized reward, not sex, drive

... parts of the brain. Moreover, different kinds of rewards (in this case, the "rush" of romantic love, compared with the pleasing experience of looking at a pretty or handsome face) is also lateralized. These results give us a lot to think about how the normal human brain learns and remembers and functions i...

After removal of the earplugs, ferrets made errors reflecting a small bias toward the previously plugged ear: they initially processed the cues as if the ear was still plugged. This aftereffect, though transient, indica...
