意识的作用及其对学习条件性眨眼反应的影响在年轻和老年参与者的跟踪和延迟辨别眨眼条件反射中进行了调查，有 4 个范式：延迟 750、延迟 1250、跟踪 500 和跟踪 1000。参与者同时观看一部无声电影，随后接受询问。无论年龄大小，追踪和延迟辨别任务的习得都与条件刺激意外事件的意识相关。在痕迹辨别中观察到年龄依赖性缺陷，但在延迟辨别中未观察到。跟踪间隔越长，缺陷就越严重。研究还发现，年轻人口中意识到这一点的参与者比例高于老年人口。这些结果表明，对刺激意外事件的认识或了解可能是成功习得高阶辨别任务的重要因素。
The role of awareness and its impact on learning the conditioned eyeblink response was investigated in both trace and delay discrimination eyeblink conditioning in young and aging participants, in 4 paradigms: delay 750, delay 1250, trace 500, and trace 1000. Participants concurrently watched a silent movie about which they were questioned afterward. Acquisition in both the trace and delay discrimination task was correlated with awareness of conditioning stimulus contingencies, regardless of age. Age-dependent deficits were observed in trace discrimination but not in delay discrimination. with more severe deficits appearing at the longer trace interval. The percentage of aware participants was also found to be greater in the young population than in the aging population. These results indicate that awareness or knowledge of stimulus contingencies may be an important contributor to successful acquisition in higher order discrimination tasks.
