Squirrel monkeys pressed a lever to produce food on several fixed-ratio schedules; they could also bite a rubber hose. Biting attack occurred during the postreinforcement pause and in early portions of the ratio response run. Also, biting attacks increased after transitions to higher values of the fixed-ratio requirement and in extinction. The results show that extinction-induced aggression effects occur in primates.
松鼠猴在几种固定比率的实验安排下通过按压杠杆获取食物;它们也可以咬橡胶软管。咬的攻击行为发生在强化后的停顿期间以及比率反应过程的早期阶段。此外,在转换到更高的固定比率要求值以及消退过程中,咬的攻击行为会增加。结果表明,消退诱导的攻击效应在灵长类动物中会出现。
