实验研究差异非条件刺激（UCS）的预期在恐惧相关（准备）和恐惧无关（无准备的）刺激显示：（a）在条件反射之前，UCS预期偏差是明显的，（B）尽管有指示告知Ss没有UCS呈现，但最初的差异UCS预期出现，（c）差异UCS预期与恐惧相关和恐惧无关的刺激消散，持续非强化，（d）不同的某些条件，（e）UCS预期和SCR措施显示出类似的行为模式，在传统的准备范式，和（f）经历CS-UCS配对似乎恢复UCS预期偏差后，它已经熄灭。 这些结果进行了讨论，作为实验室准备效果的预期模型的支持。
Experiments investigating differential unconditioned stimulus (UCS) expectancy during fear-relevant (prepared) and fear-irrelevant (unprepared) stimuli revealed that (a) a UCS expectancy bias is apparent before conditioning, (b) initial differential UCS expectancy appears in spite of instructions informing the Ss of no UCS presentations, (c) differential UCS expectancies to fear-relevant and fear-irrelevant stimuli dissipate with continued nonreinforcement, (d) differential certain conditions, (e) both UCS expectancy and SCR measures show similar patterns of behavior in the traditional preparedness paradigm, and (f) experiencing CS-UCS pairings appears to reinstate a UCS expectancy bias after it has extinguished. These results are discussed as support for an expectancy model of laboratory preparedness effects.
