80只雌性白化大鼠，在一个新的刺激面板面前进食时受到一次电击，在1-40秒的停电期后暴露于一个复杂的刺激对象，另外40只作为对照。第二天分别进行休克部位、前向条件刺激和后向条件刺激的差异回避实验。基于5种不同的行为类别，1秒、5秒和10秒停电组的神经反应者避免了后序神经反应，而不是休克位置或前序神经反应。这种关联似乎并不主要基于时间序列或巴甫洛夫条件反射中涉及的信号关系。相反，这种联系似乎依赖于刺激的特定性质，可能反映了一种进化的学习能力，将有害的外感刺激与捕食者样的物体联系起来。（22 ref）（PsycINFO Database Record (c) 2016 APA，版权所有）
80 female albino rats, shocked once while eating in the presence of a novel stimulus panel, were exposed to a complex stimulus object after a blackout period of 1-40 sec. 40 other Ss served as controls. The next day Ss were observed in a test for differential avoidance of the shock location, the forward-order conditioned stimulus (CS) and the backward-order CS. On the basis of 5 different classes of behavior, Ss in the 1-, 5-, and 10-sec blackout groups avoided the backward-order CS rather than the shock location or the forward-order CS. The association does not appear to be based primarily on temporal sequence or the signaling relationship involved in Pavlovian conditioning. Instead, it appears that the association is dependent on the specific nature of the stimuli, possibly reflecting an evolved learning capability for associating noxious exteroceptive stimuli with predatorlike objects.(22 ref)(PsycINFO Database Record (c) 2016 APA, all rights reserved)
