Pairs of rats received grid shock in a conical enclosure. Each shock elicited the stereotyped fighting posture. An omnidirectional pole, which was always between the rats, was accidentally operated whenever the rats fought. The number of pole hits, and the number of observed fight bouts, increased with current intensity. The number of pole hits served as a reliable and objective measure of shock-induced fighting in rats.
将成对的大鼠置于锥形围栏中接受电网电击。每次电击都会引发刻板的战斗姿势。一根始终位于大鼠之间的全向杆，在大鼠打斗时会意外启动。随着电流强度的增加，杆被撞击的次数以及观察到的打斗回合数也增加。杆被撞击的次数可作为大鼠电击诱发打斗的可靠且客观的衡量指标。
