Rats with either control operations or lateral, medial, or complete septal lesions received 600 trials of leverpress training using an autoshaping procedure, i.e., food delivery followed a 10 s illuminated lever presentation, or occurred immediately after a leverpress. Rats with complete septal lesions acquired the leverpress faster than controls and had more food-tray entries per minute during the first 100 trials than the other groups. Rats with lateral or medial septal lesions had leverpress and food-tray entries equivalent to controls. The facilitation of autoshaping a leverpress may partially be explained by the general increase in motor reactivity to stimuli found following septal lesions.
接受了对照手术或外侧、内侧或完全性隔区损伤的大鼠，采用自动成型程序进行了600次杠杆按压训练，即杠杆亮起10秒后给予食物，或者在杠杆按压后立即给予食物。完全性隔区损伤的大鼠比对照组更快学会杠杆按压，并且在最初的100次试验中每分钟进入食物托盘的次数比其他组更多。外侧或内侧隔区损伤的大鼠的杠杆按压和进入食物托盘的次数与对照组相当。隔区损伤后对刺激的运动反应性普遍增加，这可能部分解释了自动成型杠杆按压行为的促进作用。
