A group consisting of eight male Hooded rats was tested for risk-sensitive foraging preferences in an eight station operant arena, under conditions of open and closed economies. The group could choose to forage at either ...

Theories of resistance to extinction such as the generalized decrement theory (GDT) have been largely based on research involving isolated individuals. In the natural environment however, extinction, like acquisition ...

In two separate experiments, an 8 rat 8 station operant arena was used to study resistance to extinction to test learning and optimal foraging theories of behaviour. The learning theory, called the generalized decrement ...
