The nictitating membrane response of rabbits was conditioned at a 200 msec interstimulus interval (ISI) with either circumorbital (C) or paraorbital (P) shock as the unconditional-stimulus locus. After 3 acquisition days half of each group was shifted to a 700 msec interstimuls interval. Results indicated: (1) more rapid acquisition for Group C, (2) postshift response decrements for both groups, (3) more rapid and stable, as well as complete return to preshift performance levels for Group C. Results were discussed in terms of the response-shaping hypothesis and the contiguity-substitution hypothesis in explaining both conditional response emergence and subsequent modifications of CR topography.
以眶周（C）或眶旁（P）电击作为无条件刺激部位，在200毫秒的刺激间隔（ISI）条件下对家兔的瞬膜反应进行条件反射训练。在3天的习得期后，每组中的一半家兔被转移到700毫秒的刺激间隔。结果表明：（1）C组习得更快；（2）两组在转移后反应均下降；（3）C组恢复更快、更稳定，且完全恢复到转移前的表现水平。从反应塑造假说和邻近替代假说来讨论这些结果，以解释条件反应的出现以及随后条件反应特征的改变。
