随着（一维）信号数量及其范围的增加，绝对识别中传输的信息很快达到其上限。对这一现象有几种解释，但都是这样或那样的。在这里，我们提出了一个“记忆”或“排练”的解释。在绝对识别实验中，每个信号的基本（心理）表征被假定为相当准确，并且独立于实验中使用的其他刺激。然而，在特定试验中呈现的刺激的识别是相对于“框架”（通常是该实验中的刺激范围）的，受试者必须使用固定容量的排练系统“排练”。在特殊情况下，该模型简化为早期的建议，但其一般动机似乎比早期的想法少一些，而且它也很容易应用于多元信号的绝对识别和幅度估计。
The information transmitted in absolute identification quickly reaches its upper limit as the number of (one‐dimensional) signals, and their range, is increased. Several explanations have been given of this phenomenon, but all aread hocin one way or another. Here we present a ‘memory’ or ‘rehearsal’ interpretation. The basic (psychological) representation of each signal in an absolute identification experiment is assumed to be quite accurate, and independent of the other stimuli used in the experiment. However, the identification of the stimulus presented on a particular trial is relative to a ‘frame’ (usually the range of stimuli in that experiment) that the subject must ‘rehearse’ using a fixed capacity rehearsal system. In special cases, this model reduces to earlier suggestions, but its general motivation seems somewhat lessad hocthan that of earlier ideas, and it is also easily applied to the absolute identification of multivariate signals and to magnitude estimation.
