人们逐渐认识到，线索的联想强度在缺乏线索的情况下会发生变化，尽管这很难用现有的巴甫洛夫条件反射理论来解释。为了研究时间对学习缺失提示的表征的影响，氯化锂 (LiCl) 或之前与 LiCl 配对的风味在之前与中性目标风味配对的独特环境中呈现。无论 LiCl 是在暴露于环境之前 10 分钟还是之后立即出现，前一种处理都会产生对目标味道的厌恶。然而，仅当在初始训练期间 LiCl 10 分钟后呈现目标风味时，呈现 LiCl 的风味关联才会产生对目标风味的厌恶。这种结果模式不能用简单的计时账户来解释，并且建议解释需要在同时和连续的训练计划中运行不同的关联规则。
It is becoming accepted that the associative strength of a cue can change in its absence, despite this being difficult to explain using existing theories of Pavlovian conditioning. To investigate the influence of timing on learning about the representation of an absent cue, lithium chloride (LiCl) or a flavour previously paired with LiCl was presented in a distinctive context that had previously been paired with a neutral target flavour. The former treatment produced an aversion to the target flavour whether the LiCl was presented 10 min before, or immediately after, exposure to the context. However, presenting the flavour associate of LiCl created an aversion to the target flavour only if it had been presented 10 min after LiCl during initial training. This pattern of results cannot be explained in the terms of a simple timing account, and it is proposed that an explanation will require different associative rules operating in simultaneous and successive training schedules.
