Three experiments employed aversive or positive subcortical electrical stimulation in an unconditional stimulus (US) role in rabbit eyelid conditioning. Conditional response (CR) development to a tonal conditional stimulus (CS) was examined when the intracranial stimulation was combined with a conventional cheek-shock US (Experiment 1) or with a lightflash US (Experiment 2). Our findings were consistent with previus observations that the affective impact of the US is important in the development of an overt motor CR. The complex pattern of our results, however, implies that intracranial stimulation has multiple effects on conditioning and argues against any unidimensional interpretation of these outcomes. Our analysis of CR-contingent intracranial stimulation presentation in Experiment 3 indicated that such stimulation does not act as a Thorndikian reward or punishment in rabbit eyelid conditioning.
三项实验在兔眼睑条件反射中，将厌恶性或阳性皮质下电刺激用作无条件刺激（US）。当颅内刺激与传统的脸颊电击无条件刺激（实验1）或闪光无条件刺激（实验2）相结合时，研究了对音调条件刺激（CS）的条件反应（CR）发展情况。我们的研究结果与之前的观察结果一致，即无条件刺激的情感影响在明显的运动性条件反应的发展中很重要。然而，我们结果的复杂模式表明，颅内刺激对条件反射有多种影响，并且反对对这些结果进行任何一维的解释。我们在实验3中对与条件反应相关的颅内刺激呈现的分析表明，这种刺激在兔眼睑条件反射中并不起桑代克式奖励或惩罚的作用。
