N. Stewart, G. D. A. Brown, and N. Chater presented a relative judgment model (RJM) of absolute identification, in which the current stimulus is judged relative to the preceding stimulus. S. Brown, A. A. J. Marley, and Y. Lacouture found that the RJM does not predict their finding of increased accuracy after large stimulus jumps, except at the expense of other effects. In fact, the RJM does predict both the core effects and increased accuracy after large jumps (although it underestimates this effect) when better constrained parameters are estimated from the trial-by-trial raw data rather than from summary plots. Further, a modified RJM, in which the stimulus from two trials ago is sometimes used as a referent, provides a better fit.
N. 斯图尔特、G. D. A. 布朗和N. 查特提出了一种绝对识别的相对判断模型（RJM），其中当前刺激相对于前一个刺激进行判断。S. 布朗、A. A. J. 马利和Y. 拉库蒂尔发现，RJM无法预测他们在大刺激跳跃后准确性提高的发现，除非以牺牲其他效应为代价。事实上，当从逐次试验的原始数据而非汇总图中估计出更好约束的参数时，RJM确实能预测核心效应以及大跳跃后的准确性提高（尽管它低估了这种效应）。此外，一种经过修改的RJM，有时将两个试验前的刺激用作参考，能提供更好的拟合。
