当比较两个字母时，通常会得到比不同判断更快的相同判断。然而，当比较两个可能仅在频率上不同的音调时，相同的判断通常比不同的判断慢。一个单处理器，一维模型，克鲁格的噪声算子理论的基础上，满意地拟合数据从四个已发表的研究音调比较。由于差异的异质性，该模型预测不同判断的反应时间更快。因为一对中的第二个音调通常在频率上可以高于或低于第一个音调，所以在不同的对上比在相同的对上存在更大种类的感知差异计数。结果，大的差异计数将是决定性的，并且将导致立即的“不同”响应，因为它只能由不同的对产生，而小的差异计数将不是如此决定性的，因为它可以由相同或不同的对产生。因此，通常对相同对的重新检查比对不同对的重新检查多，并且因此对相同对的RT更长。
Faster same than different judgments typically are obtained when two letters are compared. When two tones that might differ only on frequency are compared, however, same judgments typically are slower than different judgments. A uniprocessor, unidimensional model, based on Krueger's noisy-operator theory, was fitted satisfactorily to data from four published studies of tone comparison. The model predicts faster response time on different judgments because of heterogeneity of difference. Because the second tone in a pair typically may be either higher or lower in frequency than the first, there will be a greater variety of perceived difference counts on different pairs than on same pairs. As a result, a large difference count will be decisive and will lead to an immediate "different" response, because it can be produced only by a different pair, whereas a small difference count will not be so decisive because it can be produced by either a same or a different pair. Consequently, there generally will be more rechecking on same than different pairs, and thus longer RT on same pairs.
