RA Rescorla（2002）开发的程序用于研究大鼠重复获取和消除头部进入食物杯反应的影响。在每4个20个会话阶段，食物提供在特定的30秒听觉和视觉刺激结束时，但不是在不同的30秒听觉和视觉刺激结束时。基于对单个刺激和复合刺激的反应率，获得反应率的增加比消退反应率的减少更快。在获得和灭绝之间的连续转变之后，获得而不是灭绝发生得更快。响应的时间梯度在采集过程中发展，并在灭绝过程中保持。基于平均缓解率、时间梯度和转移试验的结论是一致的。
The procedure developed by RA Rescorla (2002) was used to study the effects of repeated acquisitions and extinctions of head entry responses into a food cup by rats. In each of 4 20-session phases, food was delivered at the end of particular 30-s auditory and visual stimuli, but not at the end of different 30-s auditory and visual stimuli. Based on response rates to individual stimuli and compound stimuli, the increase in response rate in acquisition occurred more rapidly than the decrease in extinction. Acquisition, but not extinction, occurred faster after successive transitions between acquisition and extinction. Temporal gradients of responding developed during acquisition and remained during extinction. Conclusions based on mean response rate, temporal gradients, and transfer tests were consistent.
