TEMPORAL DISCRIMINATION LEARNING

这个项目的长期目标是确定 时间知觉。区分时间间隔的能力是 决策、联想、记忆和其他基本技能所需 心理过程。 拟议的研究的具体目的是确定是否有一个 有充分的经验基础相信振荡过程，而不是 而不是标量计时理论通常假定的累加过程， 参与秒到分钟范围内的计时刺激。 两个系列的实验将在老鼠身上进行；一分为二 程序中，S将探索从25ms到25.6ms的时间范围 时间感知准确性的局部不连续性；具有随机性 加固间隔计划，时间范围为12.8次至51.2次 S将探索搜索模式中的规律性。 在短期内，结果最有可能的应用是 一些简单的非侵入性神经精神病学时间测试的研究进展 这种感觉将有助于诊断几种精神疾病 精神错乱。从长远来看，这样做的价值可能是增进理解 几种生物基础之间的相互关系 精神障碍。

The long-term objective of this project is to identify the mechanism of time perception. The ability to distinguish between time intervals is required for decisions, associations, memories, and other basic psychological processes. The specific aim of the proposed research is to determine if there is a substantial empirical basis to believe that oscillatory processes, rather than the accumulation process normally assumed by Scalar Timing Theory, are involved in timing stimuli in the second-to-minute range. Two series of experiments will be conducted with rats; with the bisection procedure, the range of times from 25 ms to 25.6 s will be explored for local discontinuities in the accuracy of time perception; with a random interval schedule of reinforcement, the range of times from 12.8 to 51.2 s will be explored for regularities in the search pattern. In the short term, the most likely application of the results is in the development of some simple noninvasive neuropsychiatric tests of time perception that will serve as an aid to diagnosis of several psychiatric disorders. In the long term, the value may be to increase understanding of the interrelationships between the biological bases of several psychiatric disorders.
