Rats used in psychology experiment

This footage shows rats that have received 2 days ad libitum access to beer and water. They are observed over several days in glass cages.

They have been separated into two groups - 50% may press a lever to receive beer old (40 calories / 100 ml beer), the other 50% may press a lever for access to sucrose water (10% sugar/41 calergories/100 mls water).

At the end of the tutorial the students present their data to see how many lever pressings occurred to obtain each substance.

The aim of the experiment is to observe behavourial patterns - an objective that can easily be achieved by using a number of non-animal alternatives.
