The rats in the experiment were trained to run a maze in search of a food reward.

One mom reports that her child's preschool teacher uses a small food reward to encourage students to use the potty.

An electric shock indicates a wrong action, while a bit of food rewards success.

"If bears find food rewards near homes, they can become habituated and lose their fear of humans."

For example, food rewards, or "baiting", may work well for some individuals, but not all.

No food rewards or physical corrections are allowed at any time while competing.

Specifically, rats are able to generalize causal cues in order to gain new food rewards.

The coin, which was being reinforced with food, began to be perceived as the food reward itself by the animals.

When the rats first begin their training, they learn to associate a "click" sound with a food reward of banana or peanuts.

However, only those who didn't think they needed immunity would go to the food reward while the others played for immunity.
