Extrapolation escape test is used for studies of cognitive function in stressful conditions. A cylinder of small diameter is partially submerged in water. A rat is put into the cylinder and it has to find a way out. In the beginning it mostly jumps upwards, many times, until it realizes that it can duck, and as soon as it ducks the test is finished and the rat is put out of water. Many substances dramatically affect the ability of rats to solve the test. The number of jumps and the time spent in the cylinder is calculated.
