A method and system for automatically measuring an animal's response to his environment in a behavioral test that is indicative of the animal's mental or emotion state. For the behavioral test known as the Porsolt Forced Swim test, a pair of spaced electrodes is positioned in a tank of water in which an animal is placed. A current is applied to the electrodes to generate a voltage across the electrodes that varies with the height of the water at the electrodes and to thus provide an indication of the animal's movement in the water. The electrode signal is processed to determine the energy of the perturbations in the water caused by the animal's movement. This data is used to provide a graphical representation of the animal's activity over time. The data is also compared to one or more thresholds to distinguish various types of behavior, such as floating, swimming and climbing.
