Fighting responses were elicited by response-independent shocks delivered to pairs of rats. Food pellets were presented following different non-fighting responses to shock: some pairs of rats received pellets dependent upon a specific non-fighting response to shock; others received pellets dependent upon any non-fighting response to shock; and control pairs never received pellets. The mean probability of an elicited aggressive response to shock was reduced to 0.2 by food reinforcement for a specific non-fighting response, and to 0.5 by food reinforcement for any kind of non-fighting response. These values contrasted with the 0.8 probability of elicited aggression when pairs of rats received no food reinforcement. Consistent findings were obtained when treatment conditions were changed for individual pairs of rats.
通过对成对大鼠施加与反应无关的电击来引发打斗反应。在对电击做出不同的非打斗反应后给予食物颗粒：一些成对大鼠根据对电击的特定非打斗反应获得颗粒；另一些根据对电击的任何非打斗反应获得颗粒；而对照对则从未获得颗粒。通过对特定非打斗反应给予食物强化，对电击引发的攻击反应的平均概率降至0.2，通过对任何类型的非打斗反应给予食物强化，该概率降至0.5。这些值与成对大鼠未接受食物强化时引发攻击的0.8概率形成对比。当改变单个成对大鼠的治疗条件时，获得了一致的结果。
