Normal mice and mice with septal lesions were trained on a differential-reinforcement-for-low-rates-of-responding (DRL 8-sec) schedule for the reinforcement varying in incentive value. Dilution of diet increased the number of reinforcements received by mice with septal lesions. In Experiments 2 and 3 the effects of septal lesions on resistance to extinction and continuous reinforcement training and the strength of secondary reinforcement were investigated. Changes in reinforcement value modified the septal lesion effects in both cases. All three experiments demonstrated the alteration of the septal lesion effect through a change in the appetitive value of the reinforcement. The results suggest that one of the mechanisms by which septal lesions impair DRL performance is an enhancement of reinforcing properties of food.
正常小鼠和患有隔膜损伤的小鼠接受了不同强化价值的低反应率差异强化（DRL 8秒）训练。饮食稀释增加了患有隔膜损伤的小鼠获得的强化次数。在实验2和实验3中，研究了隔膜损伤对消退抗性、连续强化训练以及二级强化强度的影响。在这两种情况下，强化价值的变化都改变了隔膜损伤的效应。所有三个实验都证明了通过改变强化物的食欲价值来改变隔膜损伤效应。结果表明，隔膜损伤损害DRL表现的机制之一是食物强化特性的增强。
