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.

本项目的长期目标是确定 时间知觉 区分时间间隔的能力是 决定、联想、记忆和其他基本的 心理过程。 拟议研究的具体目的是确定是否存在 大量的经验基础，相信振荡过程，而不是 比标量定时理论通常假设的累积过程， 参与了秒到分钟范围内的定时刺激。 将用大鼠进行两个系列的实验; 程序，将探索25 ms至25.6 s的时间范围， 时间感知准确性的局部不连续性;随机 强化间隔时间表，时间范围为12.8 ~ 51.2 将在搜索模式中探索% s以查找错误。 在短期内，最有可能应用这些结果的是 开发一些简单的非侵入性神经精神测试的时间 这将有助于诊断几种精神疾病 紊乱 从长远来看，其价值可能是增加了解 几种生物学基础之间的相互关系 精神疾病
