The empirical goals were to describe the behavior of rats trained on multiple temporal discriminations and to use these descriptions to predict behavior observed under new training conditions. The theoretical goals were to fit a quantitative theory to behavior from one training condition, estimate parameters for the intervening perception, memory, and decision processes, and use these parameters to predict behavior observed under new conditions. Twenty-four rats were trained on a multiple-peak-interval procedure with two stimuli that were presented individually (Stimulus A and B), or in compound (Compound AB); either different responses (Experiment 1) or the same response (Experiment 2) were reinforced during the presentations of Stimulus A, Stimulus B, and Compound AB. The patterns of correct and stimulus-error responses during Stimulus A and Stimulus B (Experiment 1) were used as elements that, with summation rules, predicted behavior under new conditions (Compound AB, Experiment 1; Stimulus A, Stimulus B, and Compound AB, Experiment 2). A comparison of the success of the empirical and theoretical goals supported the use of a quantitative theory of behavior to explain the data.
实证目标是描述接受多种时间辨别训练的大鼠的行为，并利用这些描述来预测在新训练条件下观察到的行为。理论目标是将一种定量理论与一种训练条件下的行为相拟合，估计中间的感知、记忆和决策过程的参数，并利用这些参数来预测在新条件下观察到的行为。24只大鼠接受了多峰间隔程序训练，有两种刺激，分别单独呈现（刺激A和B）或复合呈现（复合刺激AB）；在刺激A、刺激B和复合刺激AB呈现期间，强化不同的反应（实验1）或相同的反应（实验2）。刺激A和刺激B（实验1）期间正确和刺激错误反应的模式被用作元素，通过求和规则来预测新条件下（复合刺激AB，实验1；刺激A、刺激B和复合刺激AB，实验2）的行为。对实证目标和理论目标成功程度的比较支持使用行为定量理论来解释数据。
