Squirrel monkeys' lever pressing produced by response-independent shock was measured before, and for an extended period following, exposure to a shock-avoidance procedure. Following avoidance training, the frequency of responding increased by multiples of 10 to 50 across subjects and evidence little or no decrement for up to 6 months of postreinforcement testing. Manual responding produced by intense environmental stimulation may be substantially strengthened by a brief history of reinforcement, such that it is sustained over long periods without reinforcement.
在松鼠猴接触回避电击程序之前以及之后的很长一段时间内,测量了由与反应无关的电击引发的杠杆按压行为。经过回避训练后,不同个体的反应频率增加了10到50倍,并且在强化后长达6个月的测试中几乎没有或没有出现反应减少的情况。由强烈环境刺激引发的手动反应可能会通过一段短暂的强化历史而得到显著增强,从而使其在没有强化的情况下长时间持续。
