TEMPORAL DISCRIMINATION LEARNING

一个定量的标量计时模型现在可以用来解释 时间歧视性能在试验和试验中汇总 研究对象。本研究的一个目标是开发一种 适用于个人试验的标量计时理论 动物。 每组10只大鼠将在四个不同的时间进行训练 需要在修复后生成单个响应的任务 时间，以固定间隔产生的重复反应， 对单一刺激的持续时间的辨别 对刺激之间重复间隔的辨别。 第一个主要问题是，时间的模型是否 歧视适用于个体动物，而不是任务。 如果是这样的话，某些参数值应该是恒定的 任务，但每个人都是一致的。 第二个主要问题是描述 用于时长辨别的内部时钟。一次尝试 将进行以确定是否存在最佳起搏器速率， 确定影响这一比率的变量，并确定是否 时间间隔或周期时钟用于在 秒到分钟的范围。

A quantitative Scalar Timing Model is now available to explain temporal discrimination performance aggregated over trials and subjects. An objective of the present research is to develop a scalar timing theory that applies to individual trials of individual animals. Groups of 10 rats each will be trained in four different timing tasks that require the production of a single response after a fixed time, the production of repetitive responses at fixed intervals, the discrimination of the duration of a single stimulus or discrimination of the repetition interval between stimuli. The first major question is whether or not the model of temporal discrimination applies to individual animals rather than to tasks. If so, some of the parameter values should be constant across tasks but consistent across individuals. The second major question is to describe the characteristics of the internal clock used for duration discrimination. An attempt will be made to determine if there is an optimal pacemaker rate, to identify variables affecting this rate, and to determine whether an interval or periodic clock is used for duration discrimination in the second to minute range.
